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.
