PreSonus ACP22 - Manual (Page 6)

Overview
close range. The gate close range is useful for creating a more natural,
acoustic sounding blend or mix.
· Stereo Channel Linking. Using the Link function, you can link together
both channels of the ACP-22 for stereo operation. When linked, both
processors follow the setting of channel one which becomes the master.
· Separate Bypass and Gain for Both Channels. Both channels
have a separate bypass for listening to 'before and after'
performance tests and a gain control to make up for any level lost
from compression.
· Compressor Sidechain Jack on Each Channel. Both channels of your
ACP-22 were designed with a special jack for spectral processing,
compression keying and ducking applications. Sidechaining is useful for
removing annoying sibilance from vocal tacks (de-essing) or automatically
ducking tracks behind a narrator for 'auto mixing' a service, broadcast or
performance. When both channels are linked together, the send of the
sidechain jack of the master channel contains a mix of both the channels in
the link; a cool feature that allows for control over both channels of
processing with one sidechain send/return. (See the section on sidechaining
for application notes.)
· Separate Gate Keying Jacks for Each Channel. Your ACP-
22 also includes a separate jack on each channel for gate keying.
This is useful for synching an external sound to a snare track for
example or putting equalizers or filters before the gate key to enable
gating only the lower frequency of a kick drum, etc.
· Balanced XLR and Unbalanced 1/4" Tip/Sleeve Inputs and Outputs.
Your ACP-22 accepts XLR connectors for balanced or 1/4" TS for
unbalanced inputs and outputs.
· +4dBu or -10dBV. The internal operating level of your ACP-22 can be
switched between +4dBu (pro levels) to -10dBV (line levels) for ease of use
in any situation.
