BASIC SETUP & APPLIC ATIONS
out, Gate Threshold knob is fully counter-clockwise, Compressor Ratio
knob is set to 1:1 (fully counter clockwise).
To set the compressor: turn the Ratio to the 2:1 mark on the legend.
With the vocalist yodeling into the mic, turn the compressorThreshold?s until
the gain reduction meters read about -7dB. Now you will probably need to
boost the compressors? output by turning the Gain knob clockwise so that
your mixer or multi-track meters read 0 dB (in the case of some digital
recorders this is -14 dB).
This would be a basic, very simple but useable setting for
recording a vocal. Things to vary to suit your taste might be: adjusting
the ratio and threshold for more/less dynamic range. Push the Soft
button in and check out the Soft Knee compression curve. Take the
compressor out of Auto mode and adjust the Attack and Release
times to taste. Get a new vocalist (just kidding).
Compressing and gating drums or percussion instruments.
Limiting the dynamic range of a drum kit may or may not be
something you want to do to your drum tracks, but there are some
other cool things the ACP-88 can do to help you get that "killer" drum
sound on tape.
If you consider the sound of a snare drum, you will notice the
sound has a beginning loud sound (transient) followed by a sound of
decreasing intensity (decay). Patch a channel of your ACP-88 for
compressing the snare drum as described above and we can explore
some dramatic changes that compression can have on the snare
drum's sound.
For a simple setup, make sure that: Soft button is out; Auto
button is out; Ratio is set to 4:1 on the legend; Attack is fully counter-
clockwise; Release is straight up at the 12:00 o'clock position; Gate
Threshold is fully counter-clockwise; Link button is out and the
Bypass button is out. Adjust the Threshold until you see about -lldB
on the gain reduction meters. At this point, the snare's volume is simply
lowered by lldB. Now slowly raise the Attack time by turning the
