Processing and Control for Professional AV Installations

Adding Third-Party Dante Devices to the User Library

The purpose of this Tech Tip is to provide instruction on how to add third-party Dante devices to the User Library of Composer. Symetrix Composer contains a list of supported third-party Dante devices. When these supported devices are added to a site file, Composer can create transmit/receive subscriptions as well as provide control for some devices.

Acoustic Echo Cancellation (AEC) Coprocessor

Adding a Radius NX AEC Coprocessor to Radius NX 4×4 or Radius NX 12×8 systems promotes the highest possible levels of clarity and intelligibility in AV conferencing and distance learning applications.

ARC-3 Adaptive Remote Control

Contemporary capacitive touch interface with LED highlighting provides users with instant operational feedback. ARC-3 Adaptive Remote Control White on black OLED display, with 256x64 pixel resolution, is graphics and multi-lingual capable to enhance readability and usability.


The Symetrix ARC-PSe provides data and power distribution over standard CAT5/6 cable for systems with more than 4 ARCs, or, when any number of ARCs are located long distances from a Integrator Series, Jupiter or Symetrix DSP unit. A half-rack form factor conserves rack space, or, if preferred, the ARC-PSe may be surface mounted. The incoming serial control signal coming from the DSP is received by the ARC-PSe on a RJ-45 input connector, and then power and signal are distributed via 8 RJ-45 output connectors. The use of off-the-shelf CAT5/6 cable and RJ-45 connectors reduces installation time and materials costs.

Core Concepts Videos: Chapter 1

This video reviews three digital signal processors (DSPs): The Prism, The Radius NX, and The Edge, sometimes referred to as Edge Frame.​ Each can be ordered in various configurations to optimize performance and flexibility for projects of any size.

Core Concepts for Open Architecture AV Design

This stand-alone version of the updated course provides an overview of the Composer software and its use in the development of professional AV installations.

Composer Control Protocol


Choosing the Best Control Server Networking Mode for Your System

Choosing the best Control Server networking mode is critical to AV system operation and security. Access Point (AP) Mode and Client Mode each are appropriate for specific use cases.

Composer Push, Pull, Sync

In Composer, there are two main ways to go online with a DSP: “Push” and “Pull.” Both have their own unique qualities that may translate to pros and cons, depending on what needs to be accomplished.

Custom Dante Rx Bus

In Composer, Dante devices added to a site file will automatically create one or more transmit channels, which then automatically create Dante receive buses in the Design view. Sometimes, a third-party Dante device will have more channels available than is desired in a Site File.

Display the Text Name of an "Active" Preset

Presets are snapshots of a given set of parameters in a given state. If a preset is recalled and one of those parameters is adjusted independently, the dropdown text box will still show the last preset recalled.

Dante Basics for Successful Audiovisual Design

Dante is an uncompressed, multi-channel digital media networking technology, with near-zero latency and synchronization. Dante does away with heavy, expensive, analog or multicore cabling, replacing it with low-cost, readily available CAT5e and higher Ethernet or fiber optic cable for a simple, lightweight, and economical solution.

Ducker Module: SymNet Designer vs SymNet Composer

This Tech Tip features the new Ducker Module in SymNet Composer. It also covers the differences between how it was used in SymNet Designer vs Composer.

Downgrade Failures Prior to Composer 6.0

The purpose of this document is to explain why certain units cannot be downgraded to Composer firmware versions prior to 6.0.

Disable xIO in Composer to Minimize Push Time

A SymNet system’s I/O can be comprised of a combination of hardware, from DSPs such as Edge, Radius12x8, or Radius AEC, to the I/O expanders such as the xIn12, xOut12, and xControl.

Dialing the SymNet Analog Telephone Interface with a 3rd Party Control System in Composer

The SymNet 2 Channel Analog Telephone Interface card (ATI card) provides a simple and intuitive solution for audio conferencing applications. Acting as a built-in telephone hybrid, the ATI card provides the means for a SymNet Edge or Radius AEC to interface directly with an analog telephone line from the local telephone company or an analog port from a digital PBX.

Debounce a Switch Connected to a SymNet Analog Control Input

All SymNet DSP units are equipped with analog control inputs. These inputs can be utilized in various ways to provide control or trigger events.

Dante PHY-to-PHY Device Audio Dropouts

The purpose of this tech tip is to provide information when troubleshooting Dante connection and subscription problems between two PHY Dante devices.



Edge scalable hardware partners with Composer® open architecture software for total design synergy. Optional networked audio connections use Dante protocol for ultra-low latency. Multiple end-user control options complete the system.

Emergency System Mute

Many AV installations may be in buildings that incorporate some sort of fire or emergency alarm system. Symetrix DSPs come with external control inputs that can take signal from this system and either mute all output audio, or even trigger other system presets. Setting this up in Composer-based products like Prism, Radius, and Edge is quick and easy. In fact, we have a super module that makes set-up even quicker.

Exporting SymVue Control Screens

SymVue Control Screens are a powerful and flexible option for system control. This Tech Tip explains how to export a single control screen to a T-7 Glass touchscreen, Control Server, and Windows PC.

Expanding Jupiter Control Using Custom Modular ARC Programming

By using SymNet Designer, the entire line of Symetrix Modular ARC panels can be made to control any parameter within your Jupiter device beyond those already available in the External Controller Wizard. You can also utilize expansion ARCs such as the EX4 and EXK giving you even more possibilities.

Executing a Windows Shutdown Command from SymVue

SymVue is our custom control screen software that comes packaged with Composer. Oftentimes, an installer will set up a Windows tablet to execute a SymVue file upon boot up, thus making things simple for the end-user and creating a fully immersive control screen environment.


Firmware Upgrade

Keeping your Symmetrics equipment firmware up to date can be an effective and relatively passive step in troubleshooting or preventing problems before they may arise, not to mention taking advantage of any current performance fixes and features.
