The "ON AIR IN – " signal turns on the "ON AIR" lamp on the console's
monitoring section.
The "CR MIC OUT" output is active if any microphone in the control
room is on (i.e. fader open, ON pushbutton active, signal routed to the
PROGRAM or RECORD bus).
The "STUDIO MIC OUT" output is active if any microphone in the studio
is on (i.e. fader open, ON pushbutton active, signal routed to the PRO-
GRAM or RECORD bus).
The "PGM OUT" output is active if any input channel is on (i.e. fader
open, ON pushbutton active, signal routed to the PROGRAM or RECORD
bus).
If set with the Customer Code (refer to
trol signal at the "Ext. CR DIM IN – " input reduces (dims) the level of the
CR monitor speakers by 20 dB.
Notes: "COMMON" can be connected either to "+5 V SUPPLY" or to an external
power supply (max. +15 V
between the control inputs and "GND". The inputs are opto-coupler inputs
with internal 1 kΩ current limiting resistors.
The outputs are open-collectors; small loads, such as LEDs, opto-couplers,
or relays can be driven directly. The current must not exceed 100 mA per
output.
The "+5 V" supply current must not exceed 50 mA.
