The GFA-5705 amplifier can drive a very 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 insure that the distortion in the amplifier would remain extremely low. This 5-channel power amplifier is ideal for home theater.
