RPA-RMT

Installation Guide

Fig. 1 RPA-RMT: Rear View

The resistor that you install deter-

mines how much attenuation is avail-

able. With no resistor installed, the

RPA-RMT will provide full attenua-

tion. Thirty-two resistors with eight

different values are included with

each pair of RPA-RMTs. These eight

resistor values range from 390 to

2.7 K ohms and will satisfy most ap-

plications. Figure 2 shows the corre-

sponding maximum attenuation for

several resistor values.

Once you know the attenuation re-

quirements for your system, use Fig-

ure 2 to determine which resistors

are needed. An equation is provided

in the P.I.P.-RPA

Reference Manual

to calculate other resistor values.

Introduction

The RPA-RMT is a two-channel, wall-

mount remote volume control for use

with the P.I.P.-RPA. It was designed

to offer an attractive, inexpensive

method for controlling audio levels in

a system that uses Crown amplifiers

fitted with P.I.P.-RPA modules. The

P.I.P.-RPA has four remote control

inputs, so two RPA-RMTs are used to

control the four channels.

Resistors

Installations often require control over

the volume range of the system. To

Resistance/Voltage

limit the system’s maximum output,

simply turn down volume controls on

the

PIP™

or the amplifier. To control

minimum output, you will need to

install resistors in the sockets located

on the back of the RPA-RMT.

One resistor socket in a parallel cir-

cuit is provided for each potentiom-

eter. When the potentiometer pulls

the output voltage below the resistor

value, the resistor allows current to

pass which will control the minimum

output for that channel.
