3 - INPUT/OUTPUT AREA
3.1 - BALANCED ANALOG AUDIO EURO BLOCK INPUTS
Connect these balanced analog audio inputs to the post-processed analog audio output from your surround
sound processor or audio preamp.
To minimize the risk of unwanted ground plane noise, use of a earth-grounded preamp is highly recommended.
Failure to connect to a properly grounded preamp/processor will likely result in unwanted ground noise that will
enter the system and be heard from the loudspeakers
.
The balanced input blocks have three terminals, from left to right: GROUND, HOT, COLD. These correspond
to pins 1-2-3 of a standard XLR audio connector. Connect XLR pin 1 (GROUND) to the left-most terminal in
the terminal block. Connect XLR pin 2 (HOT) to the middle terminal in the terminal block. Connect XLR pin 3
(COLD) to the right-most terminal in the terminal block.
Eight EURO-TO-XLR adapters are included with your ALC unit which convert the Euro connector to a standard
audio XLR female jack. Plug the Euro end into a balanced analog input and a standard XLR audio cable can be
used to connect the ALC to preamp/processor XLR outputs.
