MPS 2300
Overview and
Description. The MPS 2300 Music + Paging System is an integrated 8-
channel, 2-zone or stereo 1 -zone mixer amplifier designed
specifically for music and paging applications. The
numerous features incorporated to improve performance,
ease installation and simplify use include:
l
Switch selectable music source selection
l
LED input signal and routing indicators
l
AGC on mic channels maintain consistent page
levels
l
Adjustable muting trims set the exact amount of
muting desired
l
PowerLimit
controls set maximum level, prevent
clipping and protect speakers
l
Remote control Source Select, Page and Music
volume
l
Switchable channel input sensitivity
l
Gain, Treble, and Bass controls on music channels
to match sources
l
Active balanced inputs on Mic channels and Music
channels 1 and 2
l
Pre-out/Amp-in patch points and separate Aux inputs
for each zone
l
Direct 8 ohm/70V outputs improve damping and
lower distortion
l
Mono/Stereo linking switch
l +/-
15V power supply taps to power outboard signal
processing
l
Switched AC accessory outlet
l
Delayed Turn-on/off and DC Fault speaker
protection
The mixer/[re=amp has 2-Mic, 4-Music and 2-Aux input
channels and two Zone outputs. Except for the Aux inputs,
any channel may be routed to either or both Zones. Mic
channels are keyed; grounding the appropriate terminal(s)
activates the mic, routes it to the correct zone(s) and
triggers the music muting circuit. Mic channels have AGC
and EQ tailored to provide high intelligibility. Music
channels are switched by front panel or remote selectors.
Music channels have Gain, Treble and Bass controls.
Separate AUX channels are provided for each Zone. Front
panel controls adjust Page, Music and Master levels for

each Zone. LEDs monitor input signals and routing to each
Zone while level meters monitor the output.
Zone A and Zone B each have a 150 watt power amplifier
to drive
25-35V,
4-8 ohm loads or 70V lines. The direct-
output circuit significantly improves damping while lowering
distortion and is protected from shorts, mis-matched loads,
and thermal over-temp.
Speakers
are protected from DC
fault and the PowerLimit circuit prevents clipping, protects
speakers from excess power, and/or limits overall level to a
preset maximum.
The MPS 2300 is designed to provide years of trouble free
performance. Quality components and contemporary high
performance circuits assure optimum performance and
long-term reliability. A three year limited parts and labor
warranty is among the longest in the industry.

Important
Installation
Precautions.
l
Check the AC voltage before connecting the AC
plug. CONNECTION TO WRONG VOLTAGE WILL IM-
MEDIATELY DAMAGE THE PRODUCT, and voids the
warranty.
l
Start with the Master Volume controls all the
way off. Turn the controls up gradually until normal
operation is verified.
l
Never connect speaker barriers from different
channels together or the same speaker to more
than one channel.
l
Do not connect speaker barriers to chassis or
signal ground.
l
Keep speaker wiring separate from input wiring.
l
Always connect speakers with power off. Use
heavy gauge cable with no frayed strands or
damaged insulation.
l
Failure to observe precautions could lead to fire
or shock hazard. Never plug in a damaged amplifier
until the condition of the internal insulation is checked. If
the internal fuse blows the amplifier section is defective
and must be repaired or replaced.
l
Be sure to provide adequate support and
ventilation.
