IMPORTANT

CAUTION: TO PREVENT THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL.

The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.

7. DO NOT block any ventilation openings. Install in accordance with the manufacturer’s instructions.

8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.

9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong.The wide blade, or the third prong,are provided for your safety.If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

10. Protect the power cord from being walked on or pinched,

particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.

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.

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 provide +9 dB

boost, -9 dB cut at 10 kHz or flat response.
