Standard Compressor
1. On/Off. Turns the Compressor on or off in the signal chain.
2. Threshold. Sets the level above which the compressor
begins to attenuate the signal.
3. Ratio. Sets the relationship between the amount a signal goes above the
threshold, and the amount it is attenuated. At a 1-to-1 ratio (often written as
1:1), no compression occurs. At a 4:1 ratio, a signal that passes the threshold by
8 dB is attenuated to within 2 dB of the threshold (dividing by four). The higher
the ratio you choose, the more pronounced the compressor effect becomes.
4. Attack. Sets the time it takes for the compressor to begin
attenuating a signal, once it passes the threshold.
5. Release. Sets the time it takes for the compressor to stop
attenuating a signal once it falls below the threshold.
6. Auto. Press to toggle Auto mode on or off. When Auto mode is active, the
Attack and Release controls become inoperative, and a preprogrammed attack
and release curve is used. In this mode, the attack is set to 10 ms, and the release
is set to 150 ms. All other compressor parameters can still be adjusted manually.
7. Soft. Press to toggle Soft knee on or off. When set to on,
compression will be applied more gradually over time
when the Threshold is reached by the input signal.
Power User Tip: Very short compressor release times can produce a choppy or “jittery
sound, especially when compressing instruments that have a lot of low-frequency
components, such as a rich acoustic guitar. Very long release times can result in an
over-compressed, or “squashed,” sound. All ranges of release can be useful, however, and
you should experiment to become familiar with different sonic possibilities.
8. Gain. Sets the amount of makeup gain to apply to a signal. Once a
signal is compressed, its overall level is often reduced. This gain control
lets you bring it back up to the proper level after compression occurs.
9. Key Filter. This sets the frequency at which the compressor will
engage. The compressor will still process the entire frequency range,
but it is only engaged when the specified frequency is present.
10. Key Listen. Press to listen the signal being used to trigger the compressor,
as set with the Key Filter control (including the effects of the high-pass
filter). Press again to switch back to the normal channel signal.
