RP-C2 - Remote Panel (Input Connectors) 
Instruction Manual
RP-C2
 (Biamp #909-0171-00): The RP-C2 is a remote panel, which consists 
of one XLR and two RCA input jacks mounted on a grey ‘decorator’ style cover 
plate, with a single-gang ‘cut-in’ style PVC electrical back-box and barrier-strip 
wiring connector. An internal transformer and resistors provide summing, 
balancing, and isolation for the RCA inputs. The RP-C2 may be used to 
provide remote inputs as specified for the following BIAMP products:

The RP-C2 includes a single plug-on barrier-strip wiring connector for ease of 
installation. See associated product manuals for input wiring specifications. 
See next page for back-box installation & block diagrams. 
RCA Input Transformer Tap:
set for a 1:1 ratio (output level = input level). A jumper strap (J4) is located on 
the circuit board, above the RCA jacks, which allows the transformer input tap 
to be changed for a 1:2 ratio. This provides a 6dB increase in output level from 
the transformer. For a 1:2 ratio, move the J4 jumper strap one pin towards the 
rear of the circuit board, to the "1:2" position, using needle-nose pliers. A 1:2 
ratio may help compensate for low-level sources or signal loss in long cables. 
Output Connector:
signals from the RP-C2, for connection to inputs on the associated products. A 
common ground connection is used for both the XLR and RCA outputs. Each 
output connection is balanced, providing both a positive (+) and a negative (-) 
terminal. The unbalanced stereo RCA input signals are resistively summed 
into mono, then passed through a transformer for balancing and isolation.

Back-Box Installation 
Remove the back-box from the front panel (controls). Route cables through a 
‘knock-out’ hole on the rear of the back-box. Install the back-box in a wall or 
panel, in the same orientation as any standard single-gang electrical box. 
The mounting surface may be from 1/8” to 1” thick
(3.175mm to 25.4mm) 
The mounting cavity must be exactly 3.6” high,
2.25” wide, and at least 2.75” deep
(91.44mm H x 57.15mm W x 69.85mm D) 
Insert the back-box into the wall or panel, then tighten the flange screws until 
the flanges hold the box securely in place. Wire the remote panel pre-wired 
pigtails to the appropriate cable conductors. Soldered connections with heatshrink insulation, or properly sized wire nuts, are recommended. Mount the 
front panel to the back-box, being careful not to pinch or short the wires. 
NOTE: When an RP-S4 is used with an RIK Remote Interface Kit, the RI 
circuit board will not fit inside the standard single-gang electrical back-box. 
Therefore, the RIK must be installed external to the back-box ( 
to be connected using the wire harnesses provided). An alternative is to utilize 
a double-wide electrical back-box, which has the additional space for an RIK.
