PUBLIC ADDRESS AMPLIFIER

MA-106A

11. INPUT 1 GAIN CONTROL

Input 1 gain trim range is adjustable from 0dB to +50dB. A typical line level input setting would be close to

dB. A typical Microphone input setting would be closer to +50dB. This control is also used to fine tune the

signal threshold that will trigger the muting of input 2 or inputs 2 and 3 if linked.

12. INPUT 1 CONNECTOR

A 3.5mm Euroblock connector is used for input 1, and can be used as a mic level or line level input. As a

balanced line input, it can connect to a telephone paging system instead of a microphone. If the input signal

is unbalanced, be sure to ground the unused (-) input pin.
