Contractor Series Stereo Power Amplifiers
The Stellar Labs SLA Series of Stereo Amplifiers was designed specifically for use
in distributed audio installations, where high reliability and premium sound quality are a must. Remote on/off
triggering and signal sensing allow these units to be set up in equipment racks, with no further contact required.
Rear mounted master level controls keep installation safe from future tampering. Two auto-switching inputs
allow automatic operation when used with more than one system. Features: •Front panel controls for level,
balance and A/B speaker selection •Two sets of L/R inputs, each may be switched to accept line level speaker
level signal •Auto-switching between inputs, with adjustable delay •Line level pass through output on input #2
•Manual or auto-sensing power control •12V trigger input allows power-on command from external components
•12V trigger output allows amplifier to trigger external components •Stereo and bridged mono operation
•Heavy-duty binding post speaker outputs
•2ohm stability •Discrete output
components •THD of less than 0.2%
(at 4ohm) •See www.mcmelectronics.com
for complete details including
instruction manual.

Distributed Audio
Stereo Receiver
This receiver is perfect for music listening in any
room of the home, with conventional left/right
stereo output. What sets this apart is four amplifier
output channels, creating a self contained, four-zone
distributed audio receiver. Up to four pairs of
bookshelf, in-wall, in-ceiling or outdoor speakers
may be driven directly from this unit, with
independent selection of any or all pairs. It
is perfect in small residential or commercial
background music applications. Features: •AM/FM
tuner with 30 station presets •Five audio inputs
(including tuner) •Phono input •IR remote control
•Volume, bass and treble controls •Headphone jack
•Power output: 70W RMS x 4 (8ohm), 100W RMS x 4
(4ohm) •THD: <0.2%, 20Hz~20KHz into 8ohm
•Dimensions: 5" (H) x 17

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
front panel •Black color

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
3
1
⁄2" (H) x 6" (D).

High Power 12 Pair Speaker Switch
Controls up to 12 pairs of speakers with 250W/750W
RMS/music power cpacity. High power transformers
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
1
⁄3ohm load to appear as a 4ohm load,
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
completely isolated, allowing compatiblity with any
amplifier. Connections are made via rear mounted
terminal strip which accepts up to 10AWG wire.
Self powered unit needs no AC supply. Dimensions:
