ADCOM GFA-5705

Five Channel Home Theater Amplifier

The GFA-5705 amplifier can drive a broad range of loudspeakers, including those with very low impedances, at sustained high-power levels, even when the impedances are highly reactive. Great care was taken to ensure that the distortion in the amplifier would remain extremely low.

The power supply in the GFA-5705 has enormous reserve with an extremely large transformer feeding a storage bank of 30000uF per channel & total of 150,000uF of filter capacitance. The transformer itself was designed for extremely good regulation, insuring stable voltages regardless of the power demands from the amplifier. Its higher efficiency was insured by using a toroidal design.

Rack mounting: If the rack is mounted, the amplifier must be put on a shelf. Rack mounting brackets are NOT available for this amplifier.

All circuitry meets ETL/ETLc, FCC, LVD and CE/EMC requirements using UL approved FR-4 printed circuit boards. High performance component selections include ultra-low ESR electrolytic capacitors. The result is lower distortion, better dynamic range, improved damping factor and greater stability and separation of individual instruments on the sound stage.
