    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 75-15,000 Hz into transformer-coupled or direct low-impedance loads.

    1. Speaker Output Barrier Strip - Output terminal strip provides for 8-ohm, 25V, and 70V speaker outputs. 2. Shorting Link - Used when 25V or 70V speakers are to be connected to the GA6A. Must be removed if 8-ohm speakers are to be connected to the GA6A.
  • Page 5 Make sure that the total wattage of all the connected speakers is less than 6 watts. Note: Do not use both the 25V and 70V terminals at the same time. Use only one type of speaker (25V or 70V) for all speakers connected to the GA6A.
  • Page 6: Microphone Input

    Note: Condenser microphones will not work with the GA6A because the GA6A does not supply phantom power, which is required for these microphones to operate. Use two-conductor shielded cable for a balanced input and connect the shield to the ground terminal.
  • Page 7: Operation

    Overload Protection The amplifier output is protected against overload and shorted speaker lines by a thermostat enclosed in the power transformer. If the breaker opens, the amplifier will have no output. Set the Power switch to OFF and wait a reasonable time for the breaker to reset.
