2. GENERAL DESCRIPTION:
The PM series Mixer Amplifiers, PM-30(30W), PM-60(60W), PM-100(1 OOW), are designed
for years of trouble-free use in diverse commercial and industrial applications. They pro
vide paging, announcement, intercommunication and background music systems in in
dustrial plants, offices, churches, hotels, department stores, shopping centers, night clubs,
restaurants, convention halls, auditoriums, and stadiums. Their main feature is the ability
to withstand overload and open or short-circuiting of the output. The PM series requires
no complicated protective circuit to withstand accidents or mismatched output con
nections that may occur during the installation or use of a PA system. The amplifier is
protected by a circuit breaker when other abnormal electrical conditions occur.
Four microphone inputs are provided for High and low Impedance microphones.
Four auxiliary (Tape/Tuner, Phono, Phone, Aux) inputs are provided for signal sources
such as FM-Tuner, cassette player, remote-microphone, ceramic or crystal phonograph
cartridge, and telephone system.
Speaker outputs are complete with 4, 8, 16 ohms (usable 4-16 ohms) and 25V or 70V
line coimections. All the inputs and outputs are secured with screw terminals. Terminals
have been covered for protection against electric-shock.
There are four microphone volume controls, four auxiliary volume controls, a master
volume control, bass tone control, treble tone control, and power on/off switch, plus an
overload LED pilot lamp are provided. Also, a VU meter has been added for visual
monitoring.
