ibels (dB) by which the input signal must change in level to produce a 1dB increase in the signal level at the output of
the A 5360. A setting of 2:1 indicates an input:output ratio wherein a 2dB increase in signal (above threshold) will produce
a 1dB increase in output signal. A setting of

the output level by 1dB. In other words, the output level stays constant when the input signal rises above threshold.

The ATTACK control sets the amount of time it
sed a signal above threshold. The ATTACK range is from FAST (for a tighter and more noticeable compression effect
with very little overshoot) to SLOW (for more delayed, gradual compression). A very fast ATTACK setting will cause the A
5360 to act like a peak limiter even though RMS detection circuitry is used. Slower ATTACK settings cause the A 5360 to
act like an RMS or averaging detecting compressor/limiter.
The RELEASE control sets how fast the compression circ
m FAST (where compression follows the envelope of the program material very tightly) to SLOW (for very smooth
compression).
There is no ab

dominant signal energy, yet the release must be fast enough to avoid suppression of the desired signal after a sudde
transient or loud note has decayed. For low frequency tones (e.g., bass guitar), set RELEASE and ATTACK to 2:00 or
slower.

The OUTPUT GAIN control is especially useful to compensate
0’s dynamic processing effects. After you adjust the A 5360’s controls for the desired amount of compression (and
gating), set the OUTPUT GAIN to add the same amount of gain that is shown on the GAIN REDUCTION meters. For
example, if the average amount of gain reduction shown on the meters is 10dB, then setting the OUTPUT GAIN contro
10dB will compensate for the 10dB average level reduction at the output. Note that the OUTPUT GAIN control comes
before the Peak circuit.
