ALC REAR PANEL
3.2 - BALANCED ANALOG AUDIO LOOPING OUTPUTS
Use these balanced analog audio outputs to “loop” the analog audio input signal to another ALC chassis.
NOTE: Signal input into one of the balanced audio inputs may be routed to any ALC channel
within the same ALC via SurroundWizard™ and SoundTools™ software (refer to “ALC Program-
ming” section of this manual for more information).
3.3 BRIDGED or “BTL” STATUS INDICATORS
BRIDGED (BLUE)
This LED will illuminate when a pair of neighboring 100W channels has been “bridged” together via soft-
ware control. The result is a single 300W channel. The input for the lower number (odd number) channel
should be used to drive the bridged channels.
3.4 - LOUDSPEAKER OUTPUTS
Connect any Theory or Pro Audio Technology (PRO) passive loudspeaker system or bi or tri-amp speaker
driver to these high-current Euro Block Connectors
making sure to observe correct polarity.
The terminal blocks
will accept bare wire up to 10 gauge in size.
Note that on BRIDGED CHANNEL PAIRS, the connections should be made between the POSITIVE outputs
of the bridged channels as indicated graphically on the ALC back panel. Make sure to connect the POSITIVE
speaker conductor to the POSITIVE output of the ODD channel (lower channel connector) and the NEGA-
TIVE speaker conductor to the POSITIVE output of the EVEN channel (higher channel connector).
INCLUDED EURO-TO-XLR FEMALE ADAPTER (8 PIECES)
