50-Watt Impedance Matching Slider Speaker Volume Control
INTRODUCTION
This Impedance Matching Volume Control allows you to connect multiple speaker pairs to
a single power amplifier or receiver. It increases 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 50 watts of output
power and fits into standard single-gang low-voltage junction boxes or mounting brackets.
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.
