RELEASE defines the control time interval the
compressor takes to return to an uncompressed signal
level, after the signal dropped below the set threshold.
BYPASS activates (not engaged) or deactivates the
Compressor (engaged), which allows for quick A / B
comparison between the compressed and
uncompressed audio signal.
TONE CONTROL
The DSP block Tone Control has three filters with rotary controls to easily control the tone of the audio
signal. Each control has affect on the gain of an otherwise pre-defined filter. Making complex filter settings is not
necessary. Operation is straightforward and known from the 3-band tone controls in a mixer’s input channels.
Element Default Range Description
Switch for scaling the amplitude axis to 25 dB (± 12.5 dB) or 50
dB (± 25 dB).

BASS changes (amplifies or attenuates) the gain of a Bass filter
(Low-Shelving filter). The filter’s cut-off frequency is fixed to
666,6 Hz. The desired amplification or attenuation can be set by
directly entering the desired value or by using the rotary
control.
