Description
The GA6A is a rugged six-watt, dual-input audio amplifier with a wide variety of smaller applications including
background music, relaying communication from one room to another, or sound reinforcement.
The GA6A delivers rated power at not more than
1
% total harmonic distortion from 75-
1
5,000 Hz into
transformer-coupled or direct low-impedance loads.
Inputs for a low-impedance balanced dynamic microphone and an auxiliary audio source (tuner, tape deck, etc.) can
be mixed. Individual front-panel controls regulate the level of each input. Connections for 8-ohm and 25V or 70V
speaker lines are provided on the rear panel output terminal strip. A 3-position switch is supplied to p9 dB
boost, -9 dB cut at
1
0 kHz or flat response.
