LOOP-THRU OUTPUTS
The digital loop-thru outputs are derived as follows:
L+R (AES5)
This output provides the LEFT and
RIGHT channels of the selected digital input.
LR+RR (AES6)
This output provides the LEFT REAR
and RIGHT REAR channels of the 5.1 AES input when
this input is selected.
C+LFE (AES7)
This output provides the CENTER and
LOW FREQ channels of the 5.1 AES input when this
input is selected.
2CH2 (AES8)
This output provides the signal
present on the 2CH2 AES input regardless of input
selection.
NOTE:
The digital loop-thru outputs do not function for ADAT sources.
