Sidechain Enable - This switch enables the in and out connectors of the sidechain, allowing external
processing of the detector signal. It has no effect if there is nothing plugged into the sidechain loop;
however the switch will still light indicating the sidechain is enabled.
Sidechain Monitor Switch - This switch connects the sidechain return signal to the 1066's output. This
allows monitoring of any signal processing that is inserted into the sidechain loop to assist in setup. The
switch will light to indicate the sidechain is being monitored and the main signal path is bypassed.
Compressor Threshold Control - This control sets the level above which compression occurs, and has
a 60 dB range.
Compressor Threshold Below (-) LED - This LED illuminates when the signal is below the level set by
the COMPRESSOR THRESHOLD control. This indicates that the compressor is not compressing and is
operating in its linear region.
Compressor Threshold OverEasy® (O) LED - This LED illuminates when the signal is in the
OverEasy® portion of the compression curve. In this region the ratio varies as a function of signal level
between 1:1 and the ratio set by the RATIO control. This LED is defeated when the OverEasy® function
is disabled.
Compressor Threshold Above (+) LED - This LED illuminates when the signal is above the
OverEasy® portion of the compression curve and indicates that the full value set by the RATIO control
has been reached. If OverEasy® is disabled, this LED indicates the signal is above the level set by the
COMPRESSOR THRESHOLD control and dynamic range compression is occurring.
OverEasy® Switch - OverEasy® provides a smooth transition from the compressor's linear region to
the compressed region. This smooth transition greatly reduces compression artifacts and allows faster
attack times and higher compression ratios while still maintaining the natural characteristics of the sig-
nal. The switch lights to indicate OverEasy® processing is enabled. When conventional hard knee pro-
cessing is desired, disable the OverEasy® function. See Figure 2 on the next page.
