Known Issues

Issues Related to VoIP

  1. If a speed-dial number is selected as the transfer target, the transfer will complete immediately as a blind
    transfer.
  2. Pushing a Composer Site file to the device generates a VoIP card log message saying that the location is
    USA, even if it is not. This log message is harmless.
  3. When a local conference on a line is active and DTMF digits are pressed locally, the DTMF signals are sent
    only to the call appearance that most recently joined the conference. When establishing a conference using
    two call appearances, if it is important for one call appearance to receive DTMF digits (for example,
    a conference bridge) then add that call appearance last.
  4. There may be log messages in the VoIP card Telnet session that are categorized as ERR (error) but do not
    indicate real errors.
  5. If a local conference is using the two call appearances on line 2 and the call on the first appearance is
    ended by pressing that Call/End button, the call on the second appearance is put on hold. Press the
    appearance 2 Call/End or Hold button to resume this call leg.
  6. If the DTMF Relay type is changed to SIP INFO (default value is ‘Out of Band’), the SIP INFO messages
    are sent using the configured Transport Type for the line instead of the transport type used for a SIP dialog
    session for a call, if that is different.
  7. If the default DTMF Relay type of ‘Out of Band’ is used, and the DTMF On Time setting is increased from
    the default value of 150 ms, then rapid digit presses can result in dropped digits in the transmitted stream.
  8. When the Country parameter is set to Australia, the “ringback” and “busy” call progress tones played in the
    local room differ from the expected tones for that country. When the Country parameter is set to Germany,
    the “ringback” and “reorder” call progress tones played in the local room differ from the expected tones.
    When the Country parameter is set to the UK, the “reorder” call progress tone differs from the expected
    tone. This does not affect any call signaling, it only affects the locally generated sound effects that are
    played into the local room.
  9. If the Auto-answer feature is enabled via the Web Admin Page and there is an active call on one call
    appearance, this call is not placed on Hold when the second call is received on the other call appearance
    and automatically answered. The original call remains active with two-way audio and the second call has
    no audio. For conference room applications Symetrix recommends leaving Auto-answer turned off.
  10. If the Auto-answer feature is enabled via the Web Admin Page and a call is manually answered and placed
    on hold within the Auto-answer time window, for example before the call is auto-answered, then this held
    call is resumed automatically.
  11. If the Reset Web Admin Password button is pressed to set the Web Admin password back to its default
    value, the setting is not immediately saved. If the system is rebooted it will boot up with the old password.
    To work around this, modify a setting in the Web Admin to force files to be saved to flash memory after
    resetting the password.
  12. A consultative transfer performed by the remote party who called Line 1 of the VoIP card to Line 2 of the
    same VoIP card will not transfer the call and the initial call will be dropped.
  13. The VoIP card can indicate that it has registered successfully before the Line 1 or Line 2 “Server Address”
    field is populated. However, this field is required to place and receive calls.
  14. The Blind Transfer function where the user completes the transfer without waiting for ringback or an answer
    from the transfer target is in fact handled similarly to a semi-attended transfer. If the transfer target does not
    answer the call, the transferee remains on hold.
  15. A non-standard port number cannot be specified in a direct URI dial string, for example when dialing
    1001@10.4.0.156:8325 the destination port of 5060 is used instead of 8325.
  16. In rare cases, the HTML files used by the Web Admin may not load. Should this happen, refresh the
    browser to view the Web Admin.
  17. If the DTMF Relay type is changed to ‘In Band’ (default value is ‘Out of Band’), the duration of transmitted
    DTMF tones does not match the configured ‘DTMF On Time’ parameter in the Web Admin when the G.722
    codec is used for a call. The actual duration is shorter so the configured duration may need to be increased
    to work with certain far ends.
  18. If a firmware upgrade is performed and later a VoIP card is added or swapped, the VoIP card may not
    contain the correct Web Admin files. After adding or swapping the VoIP card, a manual firmware upgrade
    for that unit should be performed.

Other issues

  1. T-5 and T-5 Glass cannot be downgraded from 8.2 or later to 8.1 or 8.0. Attempting to do so may result
    in a screen showing only the Symetrix logo on the device. Simply upgrade to 8.2 to restore full operation
    of the device. If you need to downgrade a T-5 or T-5 Glass from 8.2 or later, contact Tech Support for
    special instructions.
  2. Units may fail to pass Dante audio when switched versus redundancy mode is changed. See instructions
    on how to change this below.
  3. Composer may fail to locate any devices. In some cases, this may require adjustments to the Windows
    firewall. Open Windows Firewall > Advanced Settings > Inbound Rules > New Rule. Specify path to
    Composer84.exe and save rule. Repeat for an Outbound rule. Restart PC.
  4. Using multiple features that access the external USB drive on Radius NX may compromise performance.
    Examples include recording, playback, and accessing files via FTP or the Media Manager. Ideally limit the
    use of these features to one type at a time, or two at most.
  5. Radius NX USB recordings are limited to 4 GB per file. Longer continuous recordings will be split up.
  6. Using a low-quality external USB drive for Radius NX recording or playback, may result in poor
    performance, dropouts, or even a device reset. Only use high quality drives.
  7. Playlists with non-US characters cannot be edited using the Media Manager. A work-around is to edit them
    manually using FTP. Similarly, audio files with non-US characters cannot be previewed using the Media
    Manager.
  8. When using a preset to mute all devices, Attero Tech and other third party devices may not be muted.
    Dante transmitters will be muted, so in most cases, they will effectively be muted because they are
    receiving no audio from Symetrix units.
  9. When an xIn, xOut, xIO, or third party Dante unit is first attached to the network, it may take up to
    two minutes to be located by Composer. When it is unplugged, it may still be visible in Composer
    for up to a minute.
  10. Some controls in Composer cannot be added to SymVue panels. For a complete list, see the SymVue
    topic in the Help file.
  11. Large button matrices in SymVue panels may adversely affect performance.
  12. Storing the settings of large matrix modules in more than 100 presets may adversely affect performance.
  13. Multiple instances of SymVue panels containing Shure microphone diagnostics may adversely
    affect performance. Minimizing the total number of Shure diagnostic controls opened in SymVue
    is recommended.
  14. There may be slight discrepancies in displayed frequencies between SymVue panels and their
    corresponding control screens. For example, in a British EQ frequency display, if the control screen shows
    200.000 Hz, the panel shows 200.002 Hz. These rounding discrepancies are visible due to the very high
    precision shown in EQ frequencies and should be insignificant since they are generally less than 0.002%.
  15. For EQ modules that are switchable between Octaves and Q, the SymVue panel will always display the
    Q value, even though the label may say “Octaves.” The label is created at the time of export and is not
    updated if the mode is changed. For best results, leave any filters in Q mode if they need to be exported
    to SymVue.
  16. In control screens with background images, it is difficult to wireframe select controls on top of the image
    since the wireframe dragging may select and move the image. To work around this, first lock the image via
    the right-click menu. Then hold down the Alt key when wireframe selecting controls.
  17. In DTMF Decoder modules, the DTMF Sequences cannot be stored in presets. However, they can be
    stored in settings files, allowing them to be moved from one module to another.
  18. If a numeric value box is placed in a control screen without its corresponding fader, it may not update
    properly. The work-around is to include the fader as well.
  19. If Dante routing or settings are changed via Audinate’s Dante Controller software, loss of functionality may
    result. Changes made from Dante Controller may be in conflict with those made through Composer. For
    best results, do not reboot the Dante hardware or change settings using Dante Controller. Use it only as a
    monitoring and troubleshooting tool.
  20. A maximum of 80 Dante units are allowed in any system. This includes Symetrix and third-party devices.
    If more than 80 are present, you may not be able to locate certain units.
  21. In the ARC-WEB dialer, if many speed-dials are populated with extremely long strings (thousands of
    characters total), the dialer may not function. This is unlikely to be an issue with “normal” usage.
  22. When upgrading the Dante Kernel Firmware for xIO devices, the upgrade may report failure when there are
    large numbers of units on the Dante network. However, the upgrade will actually succeed as verified by the
    new version number being displayed. To avoid the erroneous message, upgrade each xIO unit with only it
    and a single locating DSP unit on the Dante network.
  23. Web monitoring may not work properly if certain ad blocker browser extensions are installed.
    If you are having trouble accessing a unit’s web GUI, disable all ad blockers and/or add the unit’s
    IP address to the whitelist.

Installation Notes

If you are upgrading an existing installation that loads a configuration automatically on start-up, the following
procedure is recommended:

  1. Make sure you have a copy of the original Site file (.symx file). If it exists on your local drive, skip to
    step 2. Otherwise, use your previously installed version of Composer and choose Hardware > System
    Manager. Select the hardware that contains an archived Site file and press “Go On-line (Pull from Unit).
    Follow the prompts to save the archived file to your local drive. Make a note of its location.
  2. Turn off the automatic configuration load by going to ‘Upgrade Firmware’, clicking on ‘Erase Memory’,
    selecting only ‘Stored Site File’ and pressing Erase. Repeat for all connected units.
  3. Upgrade the firmware as described below.
  4. Re-push your entire Site file to the hardware. Open the Site file in Composer 8.4 and choose
    Hardware > Go On-line (Push Design to Hardware) (or press F4).
    Following the re-download procedure listed above guarantees that the DSP code running in your hardware is
    the correct version to work with the new firmware and Composer application code.
    Version 8.4 installs to a separate location than from previous versions on your hard drive. Version 8.4 can
    cohabitate with previous versions of Composer on your PC and will not interfere with their settings. It is
    important to note, however, that the firmware on the hardware must match the version of Composer that
    communicates with it. Version 8.4 will only communicate with hardware that is running the firmware released
    with Version 8.4, etc. If you intend to switch between versions of Composer while using the same hardware,
    you must remember to change the firmware each time. Composer checks this on download and warns you if a
    mismatch is detected.

Upgrading Firmware

IMPORTANT: In order to run Composer version 8.4, the firmware in your hardware devices must be upgraded
to the latest version. If you are receiving this software with a new device from the factory, then the firmware
versions should already be correct. However, if you are using it with an existing device, then the firmware must
be upgraded. Information about the latest release versions is always available on the Symextrix web site.
When you try to push a design to hardware, the firmware versions will be automatically checked and you will
be told if an upgrade is required. The latest firmware is always provided in the Composer installer.

Upgrading Firmware Using Auto Upgrade

  1. Follow the steps under Installation Notes above.
  2. Install Composer 8.4 using the provided Setup utility. This will copy the necessary firmware files to your
    hard drive.
  3. Launch the version of Composer that was just installed.
  4. Connect your hardware devices as they would be for normal operation. Disconnect or power down all thirdparty audio devices, especially power amps and speakers, connected to your device(s) during the upgrade.
  5. If you already have a Site file created with all units to be upgraded in it, open that and skip to step 7.
    Otherwise create a new Site file containing all units to be upgraded.
  6. For each one, locate them on the network using Hardware > Locate Hardware.
  7. Choose Hardware > Upgrade Firmware. Press the Auto Upgrade button. This will upgrade all units
    contained in the site.

If you encounter problems with this procedure or want more control over the upgrade process, try the manual

  8. Repeat steps 6 and 7 for each RS-485 device connected to that unit.
    If there are RS-485 devices connected to other units, repeat steps 5-7.

Issues With Site Files From Previous Versions of Composer

In version 8.4, the Site file (.symx file) format has changed from previous versions. You will be able to open
all previous version Site files in version 8.4 or later. However, files saved with version 8.4 may not be
readable by previous versions and/or some features may not work properly.
If you intend to maintain both 8.4 and previous versions on your computer, we recommend the following
guidelines to minimize difficulties with file formats:


A. Backup all previous design files.
It is recommended that you backup your version 8.0 or earlier design files to a secure location before using
or installing Version 8.4. Even if all else goes completely wrong, as long as you have those files, there is a
way to recreate your old setup. Note that once you save a file with Composer 8.4 and overwrite a file from a
previous version, it may no longer be readable in the previous version of Composer.


B. Don’t use the same file names for Version 8.4 design files.
If you are going to maintain both versions of the software on your PC, it is highly recommended that you
include something in the file name of all previous version files you save to indicate their version. This way you
will be able to tell the files apart if they become co-mingled.
Even if you are not going to maintain both versions, it is a good idea to use this practice at least until all your
design files have been converted and you have fully embraced Version 8.4.


C. Choose the default locations when installing software.
When you install any version of Composer software, allow the installation to go to the default folder. This
ensures that multiple versions will not interfere with each other.


D. Do not use version 8.4 software with previous versions of firmware or previous versions of software with version 8.4 firmware.
The versions of software and firmware must match! The only operation you should do that accesses
hardware with mismatched software and firmware is to upgrade to the correct firmware. Upgrading is
generally possible regardless of the firmware mismatch. If this is not the case, the release notes will make a
point of mentioning this

Changing Between Dante Switched and Redundant Mode

If Dante units are cabled for redundant mode while the units are still set to switched mode, problems such as
failure to change modes and loss of audio may occur. Use the procedure below any time a device is switched
from redundant to switched mode or vice versa. Two different procedures are required depending on if you are
using a switched or daisy-chained Dante network.

Procedure 1 – Switched Network or Direct Connection Between Only Two Units

  1. Cable the Dante network as if it were in switched mode, not redundant mode. In other words, make
    connections only to the primary jack. Alternately, if your do not have redundant-capable units that must be
    located through a DSP, you may simply disconnect the Dante network entirely. If more than two devices are
    used without an external switch, you will need to use Procedure 2 below.
  2. In Composer, go to Tools > Dante Flow Manager > Configure Dante. Select “Redundant Network” or
    “Switched Port” as appropriate.
  3. Push online with the units. This will take slightly longer than usual as the Dante units change their mode.
  4. Power down the units.
  5. Cable the Dante network as appropriate for the new mode. If switching to redundant mode, you may now
    connect the primary and secondary between two units or to separate switches.
  6. Power on the units.
  7. Again push online.

Procedure 2 – Daisy-chained Connections

  1. Connect the first two units’ primary jacks only, primary to primary.
  2. In Composer, go to Tools > Dante Flow Manager > Configure Dante. Note that in a daisy-chained
    connection, only switched mode is supported. Select “Switched Port.”
  3. In your Site file, disable everything except the first two units.
  4. Push on-line with the units. This will take slightly longer than usual as the Dante units change their mode.
  5. Disconnect the second unit and connect the third unit’s primary to the first unit’s primary.
  6. In your Site file, enable only the two connected unit.
  7. Push online. Repeat steps 5-7 for all units.
  8. Power down the units.
  9. Connect all units.
  10. Power on the units.
  11. Enable all units in your Site file. Again push online.

AlleyCat Chooses Symetrix for Mi Cocina Highland Park

AlleyCat Chooses Symetrix for Mi Cocina Highland Park

Serving authentic Tex-Mex food and excellent margaritas, the Mi Cocina restaurant chain is a favorite in the Dallas-Fort Worth Metroplex. Mi Cocina makes an extra effort to stay a step ahead of its competition, including food, service, and décor but also sound systems. “The owners of the company, M Crowd Restaurant Group, are audiophiles, and they want clear, very high quality sound and a flexible system that’s easy to use,” reports Danny Salinas of AlleyCat AV, who has designed and installed networked sound systems in 23 Mi Cocina restaurants/bars.

Recently Mi Cocina did a massive remodel of its flagship Highland Park Village location, in a high-end section of the Dallas area. Delighted with AlleyCat AV’s Dante networked sound systems at two smaller locations, which were based on Symetrix DSPs, the owners brought in Salinas to design and install their new system in the much larger and socially visible Highland Park Village restaurant and bar. “They were blown away by the sound and ease of use of the systems in the two smaller restaurants, and they wanted something similar at Highland Park Village,” he relates. “Of course the spaces are different, so the systems couldn’t be identical, but they told us to just do what we do, and they’d be happy.”

To meet the client’s goals of high quality sound, flexibility, and ease of use, Salinas designed a Dante networked audio system managed by a Symetrix Prism 8×8 DSP. A Symetrix xOut 12 Dante-to-analog output expander brought the Prism’s total I/O complement to 8 analog inputs and 20 analog outputs.

“The Highland Park location has not been renovated in over 20 years, so they gutted the whole thing and went with all new construction,” Salinas reports. “We ripped out loudspeakers that had been there more than 25 years and pulled new wire, including CAT6 cable for the network. It’s a three-story restaurant, with a rooftop balcony that’s about 100 square feet and has a glassed-in lounge and a bar they call the Monkey Bar. The second floor is a mezzanine with 10 or 12 tables, and they can have a DJ up there who projects out over the first floor below. The first floor is the main dining area and has another bar and a big entry lobby. It has 20-foot ceilings, so I mounted the speakers up high. Also on the first floor is an outdoor patio with seating. With all of that and the bathrooms, we ended up using 10 zones on the network.”

To serve the differing needs of the various spaces in the venue, Salinas chose an assortment of speakers, ranging from Tannoy ceiling speakers in the first floor entry to Fulcrum Acoustic loudspeakers with Innovox subwoofers in the main dining room, Tannoy outdoor speakers on the rooftop balcony, and other combinations of speakers elsewhere. The variety of speakers and the multiplicity of zones meant some careful programming in Symetrix’ Composer software for the Prism DSP.

“The programming wasn’t complicated but there was a lot of it,” Salinas muses. “With smaller speakers in some places and larger speakers in others, some 16 ohm and some 70 volt, I had to carefully adjust every level. With a Symetrix DSP, I have the flexibility to adjust every zone and craft it the way I want it. I used crossovers, duckers, limiters and compressors, and loudness management modules, and every zone has its own EQ. I also had to carefully look at each input and decide where I wanted it to go and how I wanted it to sound.”

Before the renovation, the restaurant had two media players for background music. In the new system, Salinas provided dedicated inputs for the two media players and added a DJ input on the mezzanine, along with a line input for a guitarist, as well as an input for plugging in an iPod or similar device. These inputs are wired analog, straight to the Prism processor.

Salinas provided easy-to-use system control with five Symetrix ARC-3 wall panels: one on the third-floor balcony, one in the third floor lounge, one on the second floor mezzanine, one indoors on the first floor, and one on the outdoor patio. He also set up a Symetrix ARC-WEB virtual user interface for browser-based control of the Symetrix system. “The owners want to be able to walk in with their phones and log into the system, and with ARC-WEB they can do that,” Salinas explains. “If they want the sound a little louder or something like that, they can easily adjust it.”

Future expansion was another consideration. “I chose the Prism with the idea of having room for growth if they want to expand the system via Dante,” Salinas confirms. “The Prism 8×8 has all of the capabilities we need, including Dante networking and plenty of analog inputs and outputs; it was a perfect match.”

Reliability is a big factor for Salinas, as well. “I have to service a lot of locations with a small company, and I don’t want to have to run out to deal with a service problem,” he relates. “With Symetrix, I haven’t had to do it yet. I’ve installed a lot of Symetrix DSPs and about 80 ARC-3s, and they always work. They have been rock solid, and they’re easy for the customer to use because Symetrix has provided the programming capability to make them that way. Mi Cocina Highland Park rotates managers because it is a training location, and all of the managers walk up to the ARC-3 control panels and use them with no problems. Best of all, the system sounds great. So far, everyone’s happy.”

Boston’s Cathedral of the Holy Cross Relies on Symetrix

Boston’s Cathedral of the Holy Cross Relies on Symetrix

The Cathedral of the Holy Cross has dominated Boston’s South End neighborhood since its construction just after the Civil War. With a seating capacity of 1,700 and a ceiling reaching to 80 feet, the cathedral is the largest Roman Catholic church in New England and the mother church for the Archdiocese of Boston. In the spring of 2017, the cathedral embarked on its first major renovation, including new LED lighting and a large and complex sound system with Symetrix signal processors at its heart. Two years and $26 million later, the cathedral reopened for Palm Sunday services.

The new sound system offers a substantial number of inputs and outputs, which are transported over a Dante network to facilitate moving signals around the sizable building. Two Symetrix Radius NX DSPs handle all of these signals, with one unit dedicated to input processing and the other handling delays to the speakers placed throughout the cathedral.

System designer Evan Landry, president and CTO of Landry Audio, a division of CommLink Integration Corp, found the versatility of the Radius NX important in meeting the substantial needs of the cathedral system. “The Radius NX provides a great deal of flexibility in terms of processing, especially with the Super Matrix, which is processed on its own SHARC chip,” Landry asserts. “We also have the ability to do logic inputs and outputs, which is handy for switching things on and off in the processing rack and essential for muting the audio system in the event of a fire alarm closure signal.”

The system currently furnishes 32 channels of input, with the Radius NX offering British EQ and highpass filter modules on each input channel. Eight channels of wireless microphones are fielded by two Shure ULXD4Q quad-channel digital receivers. Another eight channels of wired microphones for the choir are routed to two PoE-compliant Attero Tech unDX4I Dante-enabled wall plates, each of which has four mic/line inputs with preamps and phantom power.

An Attero Tech unD4I-L Dante-networked interface receives the signal from the gooseneck mic that resides on the ambo (pulpit). The unD4I-L has four channels of mic/line inputs and four channels of logic I/O. The logic is put to use to sense a pressure mat at the ambo. The ambo mic gain is increased by 5 dB in the Radius NX when the mat is stepped on and is removed when the speaker steps off the mat. This boosts the signal for speakers with soft voices, while avoiding feedback when no one is at the ambo.

Provision was made for four inputs from altar microphones but these have not yet been needed. Similarly, a Symetrix xIO 4×4 Dante-enabled analog I/O expander is installed in the choir loft but is not yet in use as of this writing because the organ has yet to be reinstalled. Anticipating future expansion, Landry had 24-core multimode optical fiber run to the loft.

On the output side, the system feeds a custom-made Innovox MicroBeam 64 line array, plus 18 more Innovox line arrays along the support columns through the cathedral: 16 in the main nave area and one in each of the transepts. PowerSoft amplification drives all of the loudspeakers. Each of these units requires its own delay time in order to synchronize the whole system. Accommodating all of these delay times became the task of the second Radius NX, and the number of discrete outputs required was dealt with by installing 4-channel analog output cards in the option slots of both Radius NX processors, as well as adding a Symetrix xOut 12 analog output expander.

Two controllers are used for mixing and control: a Microsoft Surface tablet running a user interface screen programmed by Landry in Symetrix SymView software, and a Symetrix T-5 touch screen controller. “Having a touch screen is really handy,” Landry relates. “It’s programmable, so when someone changes their mind, as often happens with new projects, we can add a volume control, for instance, with just a program change. We don’t have to put in another piece of hardware.” Landry can even do changes or troubleshoot system problems remotely by logging in through a Nook PC in the processing rack.

The PA system is far from the only sophisticated technology at work. The cathedral’s RF mic system is configured as three separate zones and employs two RF Venue Diversity Fin antennas and two Shure UA864 antennas, all of which are sent to an RF Venue 4 Zone antenna combiner. A fully equipped broadcast studio in the basement generates content for TV and webcasting and feeds the Catholic TV Network, based in Watertown, 10 miles away. One of the Radius NX processors feeds signals through the Dante network, over a Luminex switch, to the studio’s Yamaha QL1 console. From there, program audio is mixed and transmitted with video from the cathedral’s broadcast facility, up an optical fiber placed on the building’s spire, to a microwave transmitter that sends them to the John Hancock building near the city’s Copley Square, from which the signals are then rebroadcast to Watertown.

The Cathedral of the Holy Cross project took nearly three years from the time Landry first asked to bid on the project until the work was finally finished. Success in such a large project depends on good relationships, something Landry had built with the archdiocese over time. “I had worked for the archdiocese a couple of times before we installed the system for them at Our Lady of Good Voyage in South Boston in 2017. That system also included a Symetrix Radius DSP and Attero Tech wall plates. The cathedral project started shortly after the Good Voyage project completed, so we were in a good working rhythm with them, and that made all the difference.”

Symetrix’ Ease of Use Earns Raves at Arvada Presbyterian Church

Symetrix’ Ease of Use Earns Raves at Arvada Presbyterian Church

Arvada began as a small town about seven miles northwest of Denver, less than six years before Colorado attained statehood in 1876. Incorporated in 1904, it once claimed the title of “Celery Capital of the World.” Today, Arvada is a thriving commuter suburb of 112,000 people. The Arvada Presbyterian Church goes back to Arvada’s early years, beginning in 1904 with a congregation of 14. Its current main building was dedicated in 1916, making it the second-oldest church building in Arvada. An education wing was added in 1952. As of 2016, the church boasted a congregation of 245 members.

Services are mostly traditional and feature a 20- to 30-voice choir. During the summer, the choir takes a break, and three to five praise singers lead worship. An electronic keyboard and an assortment of microphones are obvious concessions to modern technology. But behind the scenes, a state-of-the-art Symetrix Prism 12×12 DSP manages the church’s sound system, offering auto-mixing with a simple user interface, with access to deeper features when needed.

“The Arvada Presbyterian Church leaders developed their sound system over the years, as technology changed,” relates Dave Kistler, president of systems integrators Equalized Productions, which designed and installed the Symetrix system. “Their old system, which used an analog mixer, was being run by high school students. When the students went to college, two members of the congregation ran the system, which was okay until those two gentlemen retired and began traveling more often. So the church asked us to design a sound system that was completely automated and could be set up for a few different scenarios, using presets, so it would sound good without requiring somebody who’s knowledgeable about audio. They wanted access to the back end, with the EQs and limiters, but they don’t intend to mess with that for the most part. And they wanted a system that could be quickly and easily reset to its standard settings. Symetrix’ Prism DSP and SymVue software enabled us to provide all of that.”

The flow of the sound system is fairly straightforward. The church has an assortment of handheld and lapel wireless microphones, the lectern mic, choir microphones (pencil condensers), and wired mics for the praise singers, plus the electronic keyboard. All told, the system uses about 20 audio channels, so the Symetrix Prism 12×12 is connected via Dante to a Symetrix xIn 12 analog input expander, for a total of 24 analog inputs, leaving room for growth. The Prism’s analog outputs feed the church’s older Crown and QSC amplifiers, which in turn drive QSC speakers in the sanctuary and Atlas in-ceiling speakers in the lobby.

“After analyzing everything, we decided to leave the existing speaker and amplification system intact because it was robust enough and complemented the facility,” recalls Kistler. “That enabled us to avoid acoustical treatment. So the main item was the Symetrix Prism. We also added Slade power sequencing, so they can turn everything on and off from the booth, and we put an amp rack in the back room. They had traditional two- or three-gang faceplate floor boxes and had problems with people breaking the mic connectors, so we installed recessed floor boxes.”

For easy and intuitive control, the Equalized Productions team provided a Dell touchscreen PC running Symetrix SymVue software. “They log into their computer, launch the application, and enter in a four-digit PIN for security purposes,” Kistler details. “That brings up a screen that allows them to go into the front-of-house mixer, the stage floor-monitor mixer, and the choir monitor mixer, each of which is independently mixed in the Symetrix Prism using the touchscreen. Preset buttons call up the different situations they’ll encounter. For example, there’s a preset for the school year, when the choir is performing, and another preset for the summer, when the praise singers are performing with handheld, wired mics.”

Symetrix DSPs are Equalized Productions’ regular go-to systems, and the Prism proved an excellent choice for Arvada Presbyterian Church. “We choose Symetrix primarily for the ease of programming,” Kistler explains. “It just makes sense. SymView was the key component that allowed us to go into the mixer and control everything. Creating the back end is so much simpler than with other DSPs. With Symetrix, I can clean up the console, so when the client launches the virtual mixers, everything is simple. I can get rid of the Solo button, the Level button, and anything else they might hit that could mess things up. We label the mixers with the channel number that is associated with the floor box, and we create labels that makes sense to them, like ‘This is Pastor Bill’s mic.’”

Kistler’s team used SymView to enable the client to log into the mixing console, mix as they wish, and then reset the system with one preset. “They also have an Admin console where they can adjust the EQs, limiting, gating, and so on,” Kistler adds. “They didn’t want to control all that stuff but they wanted to be able to see it. So they have two separate SymViews that they can log into: One is for regular control and one is Admin.” By doing all mixing and processing in the Prism, Equalized Productions was able to remove not only the old analog mixer but old rackmount gear, such as graphic EQs. “We took 32 spaces of equipment down to 2,” Kistler details. “Overall the new system looks simple and appealing. During training, they wanted us to demonstrate messing the entire mix up and then resetting the system to get back to safety. The way we programmed the Symetrix system, they hit one preset button, and that happens. They loved it; they were raving about it. That’s what’s great about the Symetrix system.”

Symetrix Enables Creative Solutions at New Life Community Church

Symetrix Enables Creative Solutions at New Life Community Church

A part of the Reformed Church in America, the New Life Community Church has been a member of the Artesia/Cerritos community in southeast Los Angeles County for more than 80 years. Most of the buildings on its current nine-acre campus were built in 1972, including a 620-seat Worship Center that hosts services, concerts, and other functions. With a stage ramp, single-level entry, a green room, and areas for props and wardrobe, the Worship Center is well equipped.

Recently, the Worship Center received a major remodel and technical upgrade, enabling the congregation to enjoy a more contemporary sound and look. The previously raked floor was filled in to achieve a flat-floor design, and new infrastructure was installed, including floor boxes, power locations, CAT5 cabling, mic and monitor lines, and more. To top it off, systems integrators TechArts of nearby Cypress, California, designed and installed a new Dante-enabled sound system based on a Symetrix Prism 12×12 DSP.

“The original install had two older Symetrix Express 8×8 DSPs, which used CobraNet,” begins TechArts programmer and associate designer Jason Vandergrift. “The current Symetrix DSPs are so much more powerful that we were able to replace both older units with one Symetrix Prism.”

One major goal of the upgrade was to improve the communications system. “There was an existing party-line-type, analog communications system that was part of the original install,” Vandergrift recalls. “It was noisy, and nobody was happy with the way it sounded. Also, with that type of system, everybody talks to everybody on Channel A or Channel B. Using the Symetrix Prism, we were able to connect a bunch of Studio Technologies 2×2 Dante audio communication devices to the network and program individual, discrete routings between them. We built everything into a mixing matrix in the Prism, and I programmed preset routings for the church’s various needs.”

The biggest issue was communications between front-of-house and the musicians onstage, but it was also important to provide flexible communications between the music director, FOH, and other volunteers. With the old system, there was no way for the music director to communicate to the sound engineer and lyrics person if, say, the band was going to skip a verse or a song, resulting in the wrong lyrics appearing onscreen.

“We also needed a system that worked with the musicians’ in-ear monitors and integrated with the talkback system they were already using,” Vandergrift notes. “With a Dante-enabled console and comm system, I could route the talkbacks into the comm system, managed with the Prism. Now the person at FOH and whoever is running lyrics or the video machine can talk directly to the music director and the production crew. We can route the FOH engineer’s comm mic to all in-ear monitors onstage. Unlike a regular talkback system, we have programmable, two-way communication. And the FOH engineer doesn’t have to dig through layers on a digital console to set up a PFL talkback.”

Routing everything through the Symetrix Prism also makes the talkback system less vulnerable. “In churches, volunteers break stuff and don’t even realize it,” avers Vandergrift. “Let’s say your talkback system is running from the FOH console, on a utility layer deep in the desk that nobody touches, and a volunteer recalls a mixer scene that doesn’t include the talkback routing. The engineer who is visiting that week has no idea that they’ve killed the talkback, and nobody can fix it. When you run it all through a Symetrix DSP, which nobody touches, you can set up a Symetrix ARC-WEB control system with a couple of presets for the comm system-I create Symetrix presets for all of the audio stuff-and the system will operate reliably.”

In addition to communications, the Prism handles the Worship Center’s PA speakers and more. “With Dante, I wasn’t limited to the Prism’s analog I/O,” Vandergrift observes. “Once audio was in the network, I set up all sorts of static routes in and out of the Prism for various purposes. For instance, I needed an ADC circuit for a broadcast mix because when the pastor was speaking the volume was too low, and the video volunteer didn’t understand how to set the volume. So I programmed a solution in the Prism.”

A devoted, long-time Symetrix DSP user, Vandergrift has a deep understanding of the products’ capabilities. “We use Symetrix on every project that requires a DSP,” he confirms. “They sound great, they’re inexpensive, and I can program them to do whatever we need. And they have a crazy amount of horsepower: With just one Prism, you can manage 64 channels of audio. The Dante-enabled Prism DSP was key to our ability to integrate the talkback and other audio systems at New Life Community Church.”
