REAR PANEL DESCRIPTION
Note: Channel One descriptions are identical to Channel Two
Outputs: XLR balanced and 1/4" unbalanced connectors for connecting
the RP583 to a mixer or other line level input.
Side Chain Input: 1/4" unbalanced jack for receiving incoming signals to
directly access the detector circuit of the compressor.
Side Chain Output: 1/4" unbalanced jack for sending out the signal
from the RP583. This jack may also be used as a pre-Output Level
output.
Note: The Side Chain Inputs and Outputs are not effects loops, they
break the signal path of the RP583 control circuits.
Inputs: XLR balanced and 1/4" unbalanced connectors for connecting
line level signals to the RP583.

FRONT PANEL DESCRIPTION
Note: Channel One descriptions are identical to Channel Two
Active Switch: Engages and disengages the compression.
Output Level: Varies the overall signal level from the RP583.
Threshold: Sets the level at which the income signal must overcome in
order for the RP583 to begin compressing.
Ratio: The signal to compression ratio - sets the amount of increase in
input signal required to raise the output signal 1 dB.
Attack: Varies the amount of time taken for the RP583 to begin com-
pressing once the Threshold level has been reached.
Release: Varies the amount of time taken for the RP583 to return to
normal gain once the signal has dropped below the Threshold level.
Stereo Link Switch: Links the detector circuits of both channels to-
gether.
NOTE: CHANNEL TWO BECOMES THE MASTER CHANNEL.
Meter Switch: Switches the signal metering from indicating the output
jack level, to indicating the amount of gain reduction.
VU Meter: Indicates either the output signal level, or the amount of gain
reduction, depending on the position of the Meter Switch.
NOTE: THE INPUT SIGNAL LEVEL MAY ALSO BE METERED BY
PRESSING OUT THE ACTIVE SWITCH, THUS BYPASSING THE
COMPRESSOR CIRCUITS.
Power Switch: Turns the RP583 main power on and off.
