DESCRIPTION

The Bogen model M0200A is a booster amplifier
designed to provide a power output of 200 watts audio
power. The amplifier can be used with any P.A. ampli-
fier or preamplifier which can provide a 2 volt signal
across 500,000 ohms at its output terminals. The
MOZOOA boosts area coverage, provides increased
reserve power and overcomes high noise, conditions.
It is excellent for use in stadiums, large auditoriums,
industrial plants, schools and all other areas where
maximum coverage is required. This high quality am-
plifier has exceptional power handling ability over the
entire range of audio frequencies.

The MOZOOA has provisions for high and low
impedance inputs. Speaker output impedance of 8 ohms
is provided as well as 25 volt (3 ohms) C.T. balanced,
70 volt (24.5 ohms) C.T. balanced and 115 volt con-
siant voltage sources, to eliminate difficulties en-
countered in speaker matching when unequal amounts

POWER OUTPUT: 200 watts

HARMONIC DISTORTION: Less than 2% at 200
watts output.

FREQUENCY RESPONSE: :2 db. 8 to 50,000 cps.

HUM: 80 db below rated output.

SENSITIVITY (for rated output): High impedance
input; better than 2 volts. Low impedance
(using TLGOO transformer); better than 0.5
volts.

F- SPECIFICATIONS

of power are required for different speakers of a
distribution system. Sockets are provided on the
chassis for power to an external preamplifier and for
connecting a remote standby power control unit.

Two or more M0200A booster amplifiers may be
connected in series or parallel to provide virtually any
reasonable voltage at any frequency or wattage. This
is made possible by interconnecting the OP. jacks of
the units and paralleling the inputs of the units. The
CF. connections tie the feedback components of the
amplifier together, thereby balancing their
characteristics.

The M0200A is also designed to serve as a power
amplifier for many industrial applications such as
ultrasonic devices, motors and servo systems. This is
possible because the amplifier can be operated at con-
tinuous full power output (100% duty cycle) and has a
115 volt output for use in driving 115 volt AC motors.

INPUTS: High impedance 0.5 megohms; Low
impedance 500 ohms (balanced) using TL600
transformer; bridging 10,000 ohms using TL 10K
line transformer.

OUTPUTS: 8 ohms balanced, 25 volt C.T. bal-
anced (39), 70V C.T. balanced (24.59) and
115 volt output (for industrial applications).

POWER REQUIREMENTS: 500 watts (5 amps at
120 volts) 50-60 cycles AC (for RA.
applications).

TUBES: 7247 (2), 8417 (8), 3 silicon rectifiers.

DIMENSIONS: 16 wide, Ill/2 deep, 6 high.

SHIPPING WEIGHT: 65 lbs.

INSTALLATION

UNPAGKING

The unit was carefully checked before leaving the
factory. Inspect shipping container and amplifier care-
fully for indications of improper handling in shipment.
If unit has been damaged. make an immediate claim
to the dealer or distributor from whom it was purchased.
If unit was shipped to you, notify transportation com
pany without delay and file a claim.

CONNECTIONS BETWEEN COMPONENTS

Use single-conductor, low capacity shielded wire

for connecting preamplifier to amplifier. Keep leads
under ten feet in length, unless cathode follower output
is employed.

Speakers may be connected with standard flexible
line cord (zip-cord) and up to 100 feet of cable may be
used without appreciable loss.

Make certain that all audio cables are kept away
from speaker cables, power cables, and power trans-
formers, and that speaker cables are kept away from
power cables.
