The EQ

The EQ allows to rearrange the pending signal in a wide 
range. It is a shelving EQ changing the low signals 
(approx 60 Hz) and high signals (approx 12 kHz). The 
range is from -14dB to +14 dB for each frequency 
range. By toggling the EQ-switch one can switch direct 
both bands from 0dB (linear) to the selected range.

THRESHOLD

The THRESHOLD determinate s the threshold where the compressor starts to 
work. In full left position (+20 dB) the compressor won't work. A full right 
position (-20 dB) means that all signals louder than -20 dB will be compressed. 
With THRESHOLD one can establish how much compression should be present 
in the audio-signal. 
Threshold determines from which signal threshold the compressor should be 
present in the audio-signal

RATIO

RATIO

RATIO

RATIO 
Ratio determines the ratio of uncompressed to compressed signal. 1: 1.5 is therefore a slight 
compression, while 1:10 can be described as a very strong compression.
For sum compression in mastering, a slight compression of 1: 1.5 or 1: 2 is preferred.

ATTACK

ATTACK

ATTACK

ATTACK
Attack determines how fast the compressor should react. The shorter the selected time, the faster the 
compression will affect the signal. The indicated time for the ATTACK switch is measured in 
milliseconds (msec).

RELEASE

RELEASE

RELEASE

RELEASE
Release determines the time after which the compressor "releases" the signal again. The longer the 
release, the longer it takes for the compressed level to return to an uncompressed state.
A special feature is the setting "AUTO". In this setting, the release time is automatically determined by
the applied signal. The compressor then adjusts the release time to the program material.
The indicated time for the REALEASE switch is measured in seconds (sec).
