Ross Graphite - 1 RU Audio Breakout Module; To Set Up Multiple 1 RU Audio Breakout Modules

1RU Audio Breakout Module
The 1RU Audio Breakout Module (ABM) provides the
audio inputs and outputs, as well as the tally and GPI
ports for the switcher. A video loop between the switcher
subsystem and the 1RU Audio Breakout Module passes
all audio signals, as well as the tally and GPI states.

Important: Ensure that Phantom Power is turned off
for the Analog Input unless you are connecting a
microphone that requires phantom power. Connecting
the line out from an audio device to the analog input
with phantom power on could damage the audio
device and/or the 1RU Audio Breakout Module. For
added safety, a TRS phone connecter should be used
for line in audio sources.
The system must be set up for the number of 1RU Audio
Breakout Modules you want to connect (up to three).
Each ABM connects to different IN and OUT BNCs on
the 4RU Integrated Production System.
