DESCRIPTION

The Bogen Mudels ClOB iuiU C20B sulid-stale public address

amplifiers are rated at 10 watts and 20 watts, respectively, and

are UL and CSA listed.

The units will accommodate most microphone types, offering

the capability for both high impedance and low impedance

microphones. A front panel selector switch allows one of the two

microphone channels (MIC 2) to be used as an auxiliary input,

which can be muted when a customer-supplied SPST normally-

opcii switch is used foi [iiiciuphuiic precedence.

Independent volume controls and a treble control, for adjust

ment of tonal balance, are provided.

Balanced or unbalanced outputs are provided for 4, 8, and 16

ohm speakers, and 25 volt constanl-vollage systems. A terminal

strip with screw terminals allows convenient connection of

speakers, except 70 volt. For 70 volt operation, a quick-disconnect

speaker socket is provided.

The ClOB and C20B amplifiers operate from a 120 volt, 60 Hz

source and have a maximum power consumption of 46 and 60

watts, respectively. A thermostat, enclosed in the power trans

former, protects the unit against overloads.

INSTALLATION

UNPACKING

The amplifier was carefully checked before leaving the factory.

Inspect shipping container and unit carefully for indication of

improper handling: if the unit has been damaged, make an

immediate claim to distributor from whom it was purchased, or if

the amplifier was shipped directly to you, notify the carrier without

delay and place your claim.

POWER AND GROUNDING

The ac line cord has a three-prong plug which should be

plugged Into a three-wire grounded, 120 volt, 60 Hz outlet. Since it

is important to ground the amplifier, where a three-wire outlet is

not available, use an adapter (e.g., Levitón No. 5017) and connect

the grounding pigtail to the screw securing the wall plate. If the

wall plate screw is not grounded, connect a wire from the GND

terminal of the amplifier to a water or steam pipe.
