CONTROLS & CONNECTIONS

•
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 dBU
) 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
connector. This signal can then be processed by an equalizer for
example to reduce sibilance 9de-essing) in a vocal track. The signal is then
returned
to
the unit via the
tip
of the connector. The signal
sent
via the
ring
could be that of a
narrator or vocalist. In this application, the audio that you are passing through the
compressor will automatically ‘
duck’
when the narrator speaks or vocalist sings.
•
Gate Sidechain/Key Insert
The
Gate sidechain
jack accepts a
tip-ring-sleeve
connector and is used to
open
the
Gate
from either a modified version of the signal passing through the
Gate
or some
other external source. For example, the
Gate
may be
Keyed
from a version of the kick
