Introduction
SymNet™ is a scalable DSP platform configured by SymNet
Designer software and made by Symetrix. Installed in
Convention Centers, Sports Arenas, Houses of Worship
and many other venues throughout the world, consultants,
integrators and end-users rely on the robust stability of the
SymNet platform.
SymNet is an open architecture system. This means DSP
modules (EQ, compression, etc.) are placed into the design and connected using standard drag-and-drop
methods. Various SymNet hardware can be chained
together to provide a custom audio solution for the client.
SymNet’s main advantage can be summed up in one word:
“Options”. Options for DSP processing, options for audio
routing and options for control.
Note: Express Cobra devices require SymNet Designer 5.0
or later.
Overview
SymNet Express Cobra is a family of 19” rack-mountable
digital signal processors (DSP) that are setup and controlled
by SymNet Designer software. Ideal for audio applications
such as churches, conference rooms, courtrooms, night
clubs and many others. ARC Wall panels easily integrate
with Express hardware and provide simple user control of
the system.
There are four analog I/O options available for the
Express line: 12x4, 4x12, 8x8, and 4x4.
Express devices
employ industry-standard CobraNet
®
technology to share
audio between devices supporting 16 inputs and 16 outputs
of CobraNet audio over Ethernet in addition to the analog
I/O.
Devices are initially configured through the RS-232 port on
the rear panel. This same port is used to connect to external
control systems from AMX, Crestron, and others. Once
the system is initially configured, Express devices can be
addressed and controlled over Ethernet.
Any of the ARC Wall Panels can be connected via CAT5
cable to an RJ-45 jack on the rear panel. One channel of
analog audio can be routed to or from the wall panel over
the CAT5 cable for simple paging or monitoring needs.
Express also includes an RS-485 port for extending the ARC
and external control capacity.
