Gain
ASA 101 ............................. +6dB (with balanced output), 0dB (with
unbalanced output)
Input Channel Output Wiring
Left Right Unbalanced Balanced
signal signal 0dB +6dB
signal ——* 0dB +6dB
——* signal 0dB +6dB
*Tested with this input unplugged
ASA 204, ASA 304 ........... Generally unity. Actual gain depends on
whether or not both inputs have signals
and also on the output wiring and DIP
switch settings. See the table below.
