5. RELEASE S (S = seconds)
The release is the amount of time it takes for the compressor to stop affecting a signal
after crossing the selected threshold. With a shorter (fast) release time, the processor
will release (let go) of the signal more quickly after the threshold is crossed. A longer
(slow) release time will allow the compressor to continue to affect the signal for a
designated period of time after the threshold is crossed. For example, a .3 release
setting will "let go" of its compression .3 seconds after crossing the selected threshold.
6. HPF Hz (High-Pass Filter - Hertz)
A high pass filter simply attenuates a selected low frequency (cutoff frequency) and
every frequency below it. All frequencies above the cutoff frequency are passed
through unaffected.

7. MAKE-UP (Make-Up Gain)
The process of compression inherently reduces the overall level of audio. Once this
occurs, you need a way to bring the overall level back up. There are a number of
ways to accomplish this; however, the simplest and most effective way is to have a
final gain stage (Make-up Gain) before the audio leaves the compressor.
8. COMPRESSOR
When selected, the compressor is engaged and operable. When not selected (bypass),
the compressor will still pass audio through without compressing your signal.
9. EXTERNAL SIDE - CHAIN
Side-chain is a term that often causes confusion. Here is what it means in its
simplest form.
115
When nothing is plugged into the side-chain input, it is the compressor alone that
determines what the audio sounds like as it leaves the compressor. However, if you
want to modify the sound before it leaves the compressor, the side-chain input is
where you can make that happen.
In this example, 105Hz has been selected as the cutoff frequency.
Therefore, the frequencies which will be attenuated are 105Hz,
and every frequency below 105Hz. All frequencies above 105Hz
will pass through unaffected.
