Input to Mic 1 will automatically ac tivate the priority circuit which temporarily
mutes signals from other inputs, tuner or tape.
1. POWER :
The P A Amplifier is to be operated fromLV-15/30 a AC120V 50/60Hz Power
source. The power required for this amplifier is c learly indicated on the
back panel.
2. INPUT CONNECTIONS :
Make connections to the microphone (high or low impedance) and
auxiliary inputs with the POWER SWITCH in the OFF position and set
corresponding volume control to zero to avoid damage to the speakers
and the amplifier from hum pickup. (Feedback)
a. MICROPHONE CONNECTIONS :
A Switch craft type A3M Microphone connector or equivalent is
required for making connections to the Microphone inputs and audio
shielded cable is required for all balanced and unbalanc ed microphone
input connections.
BALANCED MICROPHONE INPUT CONNECTIONS(MIC. 1 only) :/2
Using 2 conductor shielded cable, connect each of the two center
conductors of the cable to prongs # and of the A3M Microphone1#2
connector. Connec t the shield of the cable to prong # 1 of the A3M
Microphone connector.
UNBAL ANCED MIC ROPHONE INPUT CONNECTIONS (MIC. # 1 & # 2) :
Using single conductor shielded cable,connect the center c onductor
of the cable to prong # 2 of the A3M Microphone connec tor.

b. AUXILIARY INPUTS :
The auxiliary input receptacles and all other
phono input require an 1/4”
