CONTROLS & CONNECTIO NS
Output
The output jack accepts balanced tip-ring-sleeve or unbalanced tip- sleeve connectors. The output will deliver up to +24 dBu in signal level, balanced or unbalanced.
+4/-10 Switch
This switch adjusts the internal operating level of your ACP-88 when it is connected to line level (0 dB = -10 dBV) gear. With this switch in the ‘-10’position, the signal is adjusted by 11.2 dB so that it can be processed at the lower noise floor of your ACP-88’s internal circuitry. The signal level is lowered on the way out to match with your line level gear’s input. When the switch is in the ‘+4’position, the signal is not changed since this matches the optimum internal operating level of your ACP-88.
Compressor Sidechain
The Sidechain jack on each channel interrupts the signal that the compressor is using to determine the amount of Gain reduction to apply. When no connector is inserted into this jack, the input signal goes directly to the compressor’s control circuitry. When a connector is inserted into this jack, the signal path is broken. If you have inserted a ¼ inch tip-ring-sleeve (TRS) connector, the input signal is sent back out of the ACP-88 via the ring of the
