REMOTE CONTROL INPUT CONFIGURATION:
Audio input switching can be actuated either via external contact closure or by external positive voltage from 5
to 24VDC. Refer to the following table for wiring instructions:
CONNECTOR & FUNCTION
DESCRIPTION & COMMENTS
Connector A
Dry, for use with external switch or relay
AES input is selected with pins A1 and A3 open. To
select analog inputs short pins A1 and A3. Pin A2 is
unused.
Connector B
Wet, for use with +5 to +24VDC input
AES input is selected when no voltage is present on pin
B1. To select analog inputs, supply a positive DC voltage
between 5 and 24 volts to pin B1. Pin B3 should be
connected to remote ground. Pin B2 is unused.
FRONT PANEL CONTROLS AND INDICATORS:
Power
Confirms the presence of 24VDC from the external power supply
Analog Input Present
Left and Right Present LEDs begin to illuminate at an input level of -28dBm.
LEDs are fully illuminated when level reaches -24dBm.
Analog Input Clipping
Left and Right Clipping LEDs begin to illuminate with +18dBm input. LEDs
are fully illuminated at +20dBm.
Analog Input Gain
With a nominal +4dBm analog input, adjust these controls to set the desired
AES output level when the Analog Input is selected via remote control
Remote Active
Indicates that the remote control input on the rear panel has selected the
Analog Input. Analog Input LED will also be illuminated.
Digital Input
Indicates that the remote control input on the rear panel has selected the
Digital Input
