N OCK THE FOLLOWING PRECAUTIONS AND SAFETY INSTRUCTIONS ARE REQUIREMENTS OF UL AND CSA SAFETY REGULATIONS Warning: To reduce the risk of fire or electric shock, do not expose this unit to rain or moisture.
Unpacking the Amplifier Before your new ADCOM amplifier left our factory, it was carefully inspected for physical imperfections and tested for all electrical parameters as a routine part of ADCOM’s systematic quality control. This, along with full operational and mechanical testing, should ensure a product flawless in both appearance and performance. After you have unpacked the GFA6002/06, inspect it for physical damage.
Description of Unit GFA-6006 Features Congratulations on your decision to purchase the GFA-6002 or • Precision-matched devices used throughout the signal path GFA-6006 custom installation power amplifier. The GFA-6002 and GFA-6006 have been designed to be musically accurate in a configuration specifically designed to integrate with any home audio pre-amplifier. You have made a wise choice that will reward you for years to come with exceptionally accurate and musical sound reproduction.
Installing the GFA-6002 and GFA-6006 During normal home operation the internal heatsinks of the GFA-6002/ 6006 may become warm. However, there are instances during high-level playback into low impedances when the heatsinks will become much warmer than usual. To ensure the amplifier’s long-term, trouble-free operation it is necessary to provide adequate ventilation for the heatsinks. Therefore, the GFA-6002/6006 should be kept away from external sources of heat such as radiators and hot-air ducts.
Description of Unit: Front Panel [1] On/Standby/Vacation This LED monitors the status of operation of the amplifier. The LED will glow amber whenever the rear panel Power/ Vacation switch is in the OFF (powered down with only minimal circuitry energized) or AUTO position (amplifier is in the standby mode).
GFA-6006 Rear Panel 8 4 GFA-6002 Rear Panel 5 Description of Unit: Rear Panel [4] Inputs & [5] Outputs The audio inputs and outputs for the GFA-6002 and GFA-6006 are through high-quality, gold-plated RCA jacks to minimize high-frequency losses, noise, etc. They will accept standard RCA-type plugs, one for each of the channels. To insure that the performance designed into the amplifier is preserved, you should use the highest quality audio cables possible.
and labeled “+,” and the negative is color coded BLACK and labeled “-”. The positive terminal on the speaker will be color coded RED, or will be labeled “+,” “pos,” “positive,” “8 ohms,” or “4 ohms.” The negative terminal on the speaker will be color coded BLACK, or will be labeled “-,” “neg,” negative,” “C,” “Common,” “G,” or “ground.” Note: Bridged operation requires different loudspeaker connections. For details see the section Bridged Operation.
