Micro Infrared Repeaters & Flashers
M-1A Series Atlas Sound IR repeaters allow the operation of virtually any IR-controlled A/V component from multiple
room locations. The M-1A repeater will receive the IR signal and rebroadcast it to the small F-1 flasher LED positioned
on the front of each A/V component. The F-1 forwards the signal to the source component's IR receiver.
These micro repeaters feature an attractive, flush, white lens that blends with any white surface. Their high sensitivity
enables use within a 40 foot range with fast reaction time and minimal interference. Repeaters are available installed
on a white decorator-style subplate (cover plate not included) or separately for flush-mounting in a ceiling, wall,
cabinet or speaker grille.
F-1 Series Small F-1 flasher LEDs are shipped with an adhesive backing and 1⁄8" phone plugs for connection to
all IR-controlled A/V components. Up to six flasher units may be connected to a single M-1A repeater using two
M-1CB4B connector blocks or any standard adapter (by others).
Note: some high-end A/V components are equipped to accept hard-wired IR signals. In this case, F-1 flashers would not be necessary.

Stand-Alone IR Repeater System
M-1CB4B For installation flexibility, the M-1CB4B amplified connector block is offered as a plug-in interface device
that provides connections for an M-1A Series repeater, four F-1 flashers, and power supply Model PS-M12. This con-
figuration allows IR operation of up to four A/V components from up to four room locations. The M-1CB4B offers 1⁄8"
mini jacks for power supply Model PS-M12 and up to four F-1 flashers; it also provides terminals for wiring up to four
M-1A repeaters (rooms) in parallel fashion and a data jack for connecting a mini-pin IR source or another M-1CB4B.
The unit's amplified circuit design supplies clear, strong IR data to source components.
This stand-alone IR repeater system requires: one M-1A repeater in each remote room location, one M-1CB4B for
every four A/V components, a PS-M12 power supply, and one F-1 flasher for each A/V component. For installations
which require control of more than four components or transmission from more than four rooms, multiple M-1CB4B
blocks may be used.
Note: each M-1A repeater can control a maximum of six F-1 flashers.
PS-M12 A compact UL-listed 12VDC, 200 mA power supply with a 6' cord. The required input voltage is 120V. Supply
includes a 1⁄8" mini-plug for direct connection to the M-1CB4B connector block (powers up to four F-1 flashers) or for
use with up to two switched WhisperTouch® volume controls.

• Includes Feature Sets Perfectly Suited for Projection Systems
• Innovative, Patent Pending Through Chassis Pole Mounting System Simplifies Installation and Secures the
Amplifier
• Proven Bash™ Class A/B Amplifier Design Provides Years of Trouble Free Operation
• 2 X 70 Watts @ 8 Ω
• AC Current Sense & Audio Sense Turn-On

• UL Listed 60065
• RoHS Compliant
The PA702 pole-mount amplifier system from Atlas Sound provides an innovative solution for display systems that
require local sound reinforcement.
Since the first projector was pole mounted in a ceiling, there has been a real quandary about how to best provide local
amplification. The PA702 pole mount amplifier is a very elegant solution to solve this issue.
The PA702 includes a unique (patent pending) mounting pole installation process via a sealed hole incorporated into
the chassis design. Simply install the projector mounting pole, align the amplifier chassis hole with the 1.5" mounting
tube, and clamp the unit at the desired height above the projector mount with the innovative pole clamp system
included with the PA702. Afterwards, install the projector as normal. As a side benefit, the chassis "hole" mounting
system provides the necessary security to help deter theft.
Output is a strong 70 watts x 2 from the efficient rail tracking Class A/B and switch mode power supply technology.
The PA702 includes a host of other innovative features including an accessory outlet with AC current sense that
allows the amplifier to respond instantly from stand-by mode when the projector is powered on remotely. Also
featured are separate audio sense turn-on, balanced phoenix style and unbalanced RCA input connections, front panel
status LEDs, and recessed screwdriver adjustable tone and level controls.
The slim profile chassis is also designed to work in a rack mount configuration. An optional rack mount kit,
PA702-RMK allows single or dual mounting of the PA702 in a 1 RU high configuration.

Professional grade audio power amplifiers specifically designed for demanding contractor applications feature an
esoteric grade toroidal power supply and output transformers. These transformers were chosen for their outstanding
reliability as well as extended frequency response (-3 dB @ 30 Hz - 70.7V output through transformer). Now you can
have the peace of mind that systems will have true transformer output isolation, a feature that previously may have
not been affordable due to the cost of quality external transformers. Independent channels are driven by separate
power supplies to ensure maximum channel separation and ultra low distortion figures while providing years or
faithful service. Whether your application is a large distributed constant voltage sound system or a high SPL sound
reinforcement system, the Atlas Sound CP Series is the perfect answer for high power / low cost amplification needs.

The AA-PPRC Priority Page Relay Controller is a two-input, by two-output speaker level switch system rated at 350
watts per channel. Inserting unit into the signal path between an amplifier's output and the speaker load allows sys-
tem muting based upon a variety of external trigger sources including speaker level audio (3V to 45V), line level audio
(10mV to 3V), external contact closure or 5 to 24 volts DC.
A typical classroom installation would utilize the AA-PPRC inserted between the presentation system amplifier and
loudspeakers with a trigger input from the school's 25V paging / intercom system loudspeaker located in the same
classroom. When a page occurs the presentation system will be muted for the duration of the announcement and
will resume when the page is complete. Other applications include zone page management for new or existing
systems and priority switching of line-level audio sources. Release time of the relay control is variable from 0 to 30
seconds.
