1. Introduction
The On-Q/Legrand Speaker Level / Impedance Matching Volume Control, P/N
AU0100-WHDM-V1/AU0100-WHLA-V1 (see Figure 1), is meant to be used in a
multiple speaker distributed sound systems. These volume controls enable more pairs
of speakers to be connected to an amplifier than the amplifier could normally
accommodate (due to impedance matching ability). The impedance matching volume
controls mate perfectly with parallel audio distribution devices such as the On-Q 4 Zone
Audio Distribution Outlet (P/N 364741-xx-V1). The volume control also has a non-
impedance matching (speaker level), (1x) option to accommodate a single pair of
speakers. When used in this fashion optimum fidelity will be achieved with a single pair
of speakers.
2. Description
The On-Q Speaker Level / Impedance Matching Volume Control occupies a single gang of an electrical box and
is offered in white, almond, and light almond in an attractive decorator style. It has wiring blocks that disconnect
for easy wiring and offer impedance matching selection via jumpers labeled 1x, 2x, 4x, and 8x, (1x=non-
impedance matching), located on the circuit board. It is recommended to be installed in a low voltage bracket
such as the On-Q Single Gang Retrofit Low Voltage Bracket (F9060-01-V9), or an electrical box that is 20 cubic
inches or greater in volume.
3. Installation
Installation of the On-Q Speaker Level / Impedance Matching Volume Control is easily accomplished at multiple
times during new construction, at “Rough-in” before the drywall is installed, and at “Trim-out” after the drywall is
installed and painted or at any time following similar procedures for a retrofit opportunity.
NOTE: Before connecting the volume control: Make sure that power is not connected to the
receiver/amplifier that will be driving audio signals to the volume controls. For instructions on pre-wiring
and installing other components of any On-Q Audio System, please see the Instruction Sheets included
with those components.
A. “Rough-in”
steps:
1) A single 16/4 speaker wire should be run from the location of the audio distribution device (such as the 4
Zone Audio Distribution Outlet) to a single gang outlet box or low voltage bracket at each Volume Control
location.
Note: It is recommended that a minimum of 16 gauge 4 conductor
wire be run for most applications from the audio distribution device
to the volume control. Different gauge wire can, and should, be
used based upon the distance of the intended run or quality of
installation (see Figure 2) . It is recommended that wire gauge not
be less than 18 gauge. The impedance matching volume control can
