1: THRESHOLD: variable between -30 dBu and +10 dBu. When the input level reaches the level set
by this control the compressor will start to act and alter the dynamics of the input channel. When the
sound level and the input stays under the threshold, the compressor is not active and there will be no
change to the dynamics of the input channel.
2: RATIO: indicates the amount of compression that will be applied to the input signal when this signal
exceeds the threshold level. Variable between 1:1 (no compression, linear transfer function) and ∞:1
or infinity:1 (limiting: the input level may continue to rise, the output level will stay quasi fixed).
3: ATTACK: variable between 1mseconds and 0,1 seconds. This parameters sets the time it will take
the compressor to reach full compression (as set by the ratio control) when the input level exceeds the
threshold level.
4: RELEASE: the time it will take to return to a linear transfer function when the input level has drop-
ped under the threshold level again. In other words: how long it will take the dBC-8 to stop compressing
when the signal is under the threshold.
