Functional Description
The RPD-2200 is a dual dynamics processor with link option for expansion, gating, compressing, peak
limiting, de-essing and enhancing of audio signals. Automation functions for compression param-
eters, comprehensive manual parameter adjustment options and level virtualizations make this unit
suitable for a large variety of applications in recording, live sound and installation environments.

AC inlet and fuse holder. Use the supplied AC cord to connect the unit to AC mains. Make sure
voltage and frequency stated and set on the unit comply with your local AC supply. The fuse
can be accessed by the small drawer at the AC inlet. To change the fuse, unplug the AC cord
first, pull out the fuse drawer and replace the fuse ONLY with a fuse of SAME voltage and
rating. If the fuse blows again after replacement, hand over the unit to qualified service person-
nel.
CHANNEL XLR INPUT. This is a balanced XLR connector wired in parallel with the TRS connec-
tor (3).
CHANNEL TRS INPUT. This is a balanced TRS connector wired in parallel with the XLR connec-
tor (2).
SIDECHAIN SEND. This is the unbalanced sidechain output, which allows you to route the audio
signal to other devices for external processing.
SIDECHAIN RETURN. The sidechain input allows you to use an external signal or the processed
(e.g. with an equalizer) audio signal routed from the SIDECHAIN SEND jack for external control.
OPERATING LEVEL switch. This switch can be used to adapt to various operating levels, i.e. to
toggle between home recording level (-10 dBV) and studio level (+4 dBu). The level meters will
be referenced automatically to the nominal level adjusted, so that the compressor works in its
optimum operating range.
CHANNEL XLR OUTPUT. This is a balanced XLR connector wired in parallel with the TRS
connector (8).
CHANNEL TRS OUTPUT. This is a balanced TRS connector wired in parallel with the XLR
connector (7).
EXPANDER/GATE TRIGGER. This control determines the threshold below which expansion
sets in, so that signals below threshold are reduced in gain. The setting range is from OFF to
+10 dB.
EXPANDER/GATE DISPLAY. If a signal below the adjusted value is applied, the left red LED
(expansion on) lights up. If the signal gain is above the adjusted value, the right white LED lights
up.
EXPANDER/GATE DISPLAY RELEASE switch with LED. To adapt the expander/gate optimally
to the program material, use this switch to select a short or long release time. Percussive
material with little or no reverb at all is usually processed with a short release time (switch not
pressed). The long release time is the best choice for slowly decaying or heavily reverberated
signals (switch pressed).
EXPANDER/GATE MODE switch with LED. This switch toggles between the expander function
(switch not pressed) and the gate function (switch pressed). Use the gate function to mute
signals below threshold (e.g. noise).
COMPRESSOR THRESHOLD. This control adjusts the compressor threshold from -40 to +20
dB.
