COMP-01 Auto Make-up Gain Compressor
! Please, note that this device is not available in Reason Intro Rack Plugin.
The COMP-01 compressor levels out the audio, by making loud sounds softer. To compensate for the volume loss,
the device has an automatic make-up gain, that raises the overall level by a suitable amount. The result is that the au-
dio levels become more even and individual sounds can get more “power” and longer sustain.
The COMP-01 should be used as an insert effect, either for a single instrument device or for a whole mix (e.g. in-
serted between a Mixer device and the Hardware Interface). There are no CV inputs for this device.

Description
Ratio This lets you specify the amount of gain reduction applied to the signals above the set threshold. The
value is expressed as a ratio, from 1:1 (no reduction) to 16:1 (levels above the threshold are reduced by
a factor 16).
Threshold This is the threshold level above which the compression sets in. Signals with levels above the threshold
will be affected, signals below it will not.
In practice, this means that the lower the Threshold setting, the more the compressor effect.
Attack This governs how quickly the compressor will apply its effect when signals rise above the set threshold.
If you raise this value, the response will be slower, allowing more of the signal to pass through the com-
pressor unaffected. Typically, this is used for preserving the attacks of the sounds.
Release When the signal level drops below the set threshold, this determines how long it takes before the com-
pressor lets the sound through unaffected. Set this to short values for intense, “pumping” compressor
effects, or to longer values for a smoother change of the dynamics.
Gain meter This shows the amount of gain reduction or increase (in dB), caused by the combined compression and
make-up gain.
