Section 4
Within the multiband compressor menu on the IEM the following parameters are user adjustable
on all programs.
Compressor LOC/On/Off
Local (per band control) on and off.
Band 1 to 4 On/Off
Turns on or off each independent band
OverEasy® 1-10 (per band)
The point when the IEM (or any compressor) starts to compress is the "knee." When the IEM
starts to reduce the level of a signal abruptly right as it passes over the threshold this is called
"hard knee" compression. OverEasy® (soft knee as it is sometimes called) is when the level of
the signal is compressed gradually. OverEasy® compression starts to compress before the level
of the signal reaches the threshold and reaches full compression after the signal has gone above
the threshold. This OverEasy® compression by its very nature sounds much smoother and more
natural and will be used for most applications. When it is gentle (natural sounding or light) com-
pression that you are looking for, the IEM has what we call VariKnee™. VariKnee™ gives you
ten levels of OverEasy® compression to choose from (1 being almost hard knee and 10 being
the most OverEasy®). This lets you choose the exact knee that is needed for the dynamic effect
you are looking for.
Auto LOC/On/Off and Auto On/Off
Auto can be turned on/off per band or globally. When Auto mode is on, the IEM automatical-
ly sets the Attack, Hold, and Release times for the signal. The auto mode constantly adjusts these
parameters in real time for optimum performance from the unit.
