OVC300 300-Watt Impedance Matching Outdoor Volume Control

P/N 38178

Quick Install Guide

INTRODUCTION

This Impedance Matching Outdoor Volume Control allows you to connect multiple speaker

pairs to a single power amplifier or receiver. It increases (or decreases) the impedance of

the connected speaker pair to ensure that the overall impedance level presented to the

amplifier is high enough to prevent damage to the amplifier. It can support amplifiers with

up to 300 watts of output power and has a waterproof enclosure, allowing it to be used in

outdoor applications.

INSTALLATION

Perform the following steps to install one or more volume controls to your stereo system.

These instructions assume that you have already installed all speaker pairs and low-voltage

mounting brackets at the desired locations.

1. Refer to your amplifier's manual to determine the minimum impedance level that

can be safely connected. In most cases, the minimum impedance is 4, 6, or 8 ohms,

though some amplifiers are stable down to 2 ohms.

2. Determine how many speaker pairs are to be connected and the nominal

impedance of each pair. Note that only a single pair of speakers should be

connected to each volume control.

3. Refer to the following tables to determine the switch settings for each

volume control, depending on the minimum impedance load of your

amplifier, then set the switches on all volume controls to the indicated value.

General

Check amplifier manual for minimum impedance and count speaker pairs. Connect only one pair per volume control.

Use provided tables to determine switch settings based on amplifier capability and speaker load.

Connect speaker wires to volume control outputs and amplifier wires to inputs, then mount the enclosure securely.

Secure cover plate, attach knob, and connect all speaker wires to the amplifier's terminals.

Set amplifier volume to minimum, power on, and adjust zone controls for desired listening levels without distortion.
