Biamp RP-C2 Instruction manual
Biamp RP-C2 is a remote panel that provides mic/line inputs for various Biamp products, including mixers, amplifiers, and matrix switchers. It features an XLR input and two RCA inputs, which are summed and balanced internally using a transformer for isolation. The RP-C2 also includes an output connector with balanced XLR and RCA outputs for connecting to the inputs of compatible devices. The RCA input transformer tap can be adjusted for a 1:1 or 1:2 ratio to compensate for low-level sources or signal loss in long cables.

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: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . functions Mic/Line Inputs Mic/Line Inputs Mic/Line Inputs Mic/Line Inputs Mic/Line Inputs Mic/Line Inputs Mic/Line Inputs Mic/Line Inputs Line Inputs Line Inputs push products 801 Mic/Line Mixer . . . . . . . 601 Mic/Line Mixer . . . . . . . 301 Mic/Line Mixer . . . . . . .

See next page for back-box installation & block diagrams. Output Connector: This plug-on barrier-strip connector provides the output 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. Biamp Systems, 10074 S.W.

RCA XLR (503) 641-7287 transformer output connector RCA Input Transformer Tap: From the factory, the RCA Input Transformer is 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. www.biamp.com Back-Box Installation Back-Box flange 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) knock-outs 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 RIK circuit board will not fit inside the standard single-gang electrical back-box. Therefore, the RIK must be installed external to the back-box (yet close enough 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. flange RP-C2 Block Diagram 2 3 + - 1 + - 585.9171.00 Biamp Systems, 10074 S.W.
