Stereo Volume Controls
In-wall volume controls utilize high quality
multitap audio transformers and smooth 12
position rotary switches to provide full
range level control. They are designed for
use in distributed audio systems, primarily
those involving in-wall and ceiling speaker systems.
Available in single gang steel plate and decora style
all units are shipped as white, with ivory plates and
knobs included for easy color conversion. Standard
units are available in 25W RMS and 100W RMS
versions, impedance matching models are 100W RMS.
Impedance matching design allows of up to 16 pairs of
8ohm speakers to be connected to a single stereo
amplifier, and appear as a 4ohm load. Features:
•Detachable terminal strips accept up to 14AWG
wire •Included matching cover plates with decora
models •May be mounted in a single gang box or
low voltage bracket Specifications: •Frequency
response: 35Hz~20KHz •Attenuation: -34~0dB,
in 12 steps •Impedance matching (applicable
models only): x2, x4 and x 8ohm

Audiophile Grade Stereo Volume Control
Transformerless volume controls are ideal for use
with any in-wall or ceiling speaker system, where
local control is desired, and pure sound quality is a
must. High–quality, close tolerance audiophile grade
resistors are used instead of conventional audio
transformers, allowing full 20Hz~20KHz frequency
response to pass through to the speaker. This single
difference provides performance that is superior to
virtually any transformer based control, at any price.
Rotary control provides 0~36dB attenuation in 11
steps, with position 12 being off. All models include
white and ivory cover plate and knob to match any
décor. Detachable terminal strips greatly ease
installation and will accept up to 14AWG cable.
Control mounts in standard single gang boxes or
mud rings, and includes decora style cover plate.
Power capacity: 60W RMS per channel.

In-Wall Switch Boxes
Designed to operate four pairs of
loudspeakers of 4ohm or higher
impedance with no heat developed,
even when all speakers are run
simultaneously. Can handle up to
72W RMS or 216W audio
35Hz~20KHz. Will fit in standard
single gang junction box.

Impedance Protected
Speaker Selectors
Low–profile speaker distribution
systems enable on/off control to four, six or eight pairs
of speakers, while providing impedance protection to
the amplifier. Source A/B selector for each zone allows
independent selection from two different sources to
each speaker pair. Non–inductive resistor network
maintains impedance above 4ohm, regardless of
the number of 8ohm speakers selected. Since
resistors are used instead of commonly used
transformers, much wider frequency response is
maintained through the selector. Terminal strips
accept up to 12AWG wire, and are fully removable
to ease installation. Specifications: •Power capacity:
70W with impedance protection, 140W without
•Aluminum chassis with extruded aluminum

Speaker Selector Switches
with Volume Control
Versatile speaker switches allows connection of up
two six pairs of speakers, to two different stereo
sources, with individual volume control of each pair.
Each speaker pair has an independent pushbutton
selector for “Source A” and “Source B”, and an
11 position rotary volume control. Volume
adjustment and impedance matching is
accomplished through internal heavy-duty
multi-trapped transformers. For each speaker,
this allows complete, independent control of each
pair, with maximum efficiency, and virtually no
generation of heat. Rear screw terminal strips accept
up to 14AWG wire, and are removable, allowing easy
connection of multiple cables. Power capacity:
18W/50W RMS/program per speaker, 100W/150W
RMS/program total. Housed in an extremely rugged
steel enclosure, these units are ideally suited in
component racks or shelves. Dimensions: 3" (H) x
17" (W) x 7" (D), including knobs.

High Power Eight Pair Speaker Switch
Controls up to eight pairs of speakers with
250W/750W RMS/music power capacity. High power
transformers with selectable taps allow you to
obtain maximum power transfer while maintaining
a safe load of 4ohm or higher. Because the system is
capable of transforming a
1
⁄3ohm load to appear as a
4ohm load, several speaker pairs may be used on a
single switch position. The left and right channels
are completely isolated, allowing compatibility with
any amplifier. Rear mounted terminal strip which
accepts up to 10AWG wire. Dimensions: 17" (W) x

with selectable taps allow you to obtain maximum
power transfer while maintaining a safe load of
4ohm of higher. Because the system is capable of
transforming a

several speaker pairs may be used on a single switch
position, allowing more than 12 pairs of speakers
to be connected. The left and right channels are
