ARC-XLR
The ARC-XLR is
a modular remote
control for Symetrix
DSPs that combines an
XLRaudioconnection
and push-to-talk button
with the ARC-SW4’s four
momentary pushbutton
switches that provide the
client with simple control
over zone selection plus
paging and more. Each
of the five pushbuttons
havecorrespondingtri-colorLEDswhichcanprovideuser

orLEDsandbuttonsmaybeprogrammedindependently.

input or output for the system to create a paging station or
remote monitoring device. There is an onboard microphone
preamp.Allcontrolassignments,includingbuttonandLED
functionality, parameter limits and firmware version upgrades
are handled by the software included with Symetrix DSP
hardware. Power, control, and a single channel of ARC
Audio (for the onboard mic) are connected via RJ-45 inputs
or screw-type barrier strips. The ARC-MIC also supports
“sleep” mode for light-sensitive environments like theaters.
Hardware lockout pins are provided to accommodate
aninstaller-suppliedkeyswitch.TheARC-XLRissplash-
resistant and mounts into a single gang electrical box
(US), finished with a standard Decora
®
faceplate
(supplied in white).
ARC-EX4
The ARC-EX4 is the expander version of
the ARC-SW4. Identical in form and function
to the ARC-SW4, it expands the capabilities
of a Modular ARC Wall Panel. The ARC-

ARC-MIC 2 3
ARC-XLR 2 3
ARC-EXK
The ARC-EXK is the expander version of
the ARC-K1. Identical in form and function
