THR Threshold sets the threshold of the compressor. A lower threshold means a larger portion of the
signal is subject to compression.
ATK Attack sets the time of the compressor attack phase, i.e. how quickly the compressor responds
to loud peaks.
REL Release sets the time of the compressor release phase, i.e. how long it takes for the compression
to recover in quieter moments.
MUP Makeup Gain sets the makeup gain of the compressor output, to compensate for the reduced
signal levels caused by compression. The Makeup Gain parameter value is displayed in dB.

RATIO Compression Ratio. There are eight different compression ratios, 1.50, 2.00, 3.00, 4.00, 6.00,
8.00, 16.00 and 20.00. Higher ratios result in greater compression of the signal.
SC FLTR Sidechain Filter filters the audio signal before the compressor analyzes it. The parameter
ranges from a low-pass filter to a high-pass filter. Negative parameter values sets a low-pass filer.
Positive parameter values sets a high-pass filter.
When set as a low-pass filter, the compressor reacts mostly to bass frequencies. Use this setting for a
characteristic pumping compressor sound. When set as a high-pass filter, the compressor reacts less
to bass frequencies. Use this setting to avoid pumping.
MIX Sets the mix between the clean signal and the signal that is affected by the effect.

7.3.6 BASS FOCUS
This FX block can be used to detect and correct any stereo phase problems in the low-end register of
the signal. It uses a crossover filter to divide the signal into a low band and a high band, allowing you to
make the low band part of the signal mono. You can also attenuate the two bands separately. The -1 to
1 meter displays the amount of phasing in the low band. A positive value means that the signal does not
