Stereo Link
NOTE: Both compressors must be IN, assigned to the program bus, with the link
engaged to apply proper stereo mix compression. When LINK is engaged
the gain reduction control voltage is summed. To assure that gain reduction
is keyed equally by both left and right channels it is essential to set
parameters on both compressors exactly the same.

Compressor Parameter Controls
NOTE: Automatic make-up gain is applied so the compressor output remains fairly
constant regardless of the threshold and ratio settings. This allows for live
adjustments to be made with noticeable changes in perceived level.
THRESH (threshold): Sets the level at which compression begins
•
Continuously variable b10dBu and -20dBu
•
Detented rotary pot for easy recall
LINK: Activated DC link between compressions 1 and 2
•
Stereo compression when engaged
•
Sums the DC gain reduction voltage of both units
•
Illuminates when engaged
RATIO: Sets the compression ratio of input vs. output levels for signals
that fall above the set threshold
•
Continuously variable between 1:1 and
∞
:1
•
A ratio of 10:1 or greater is generally considered to be limiting
