ADCOM GFA-555ms Power Amplifier

Description Specifications For those who desire the power finesse in a two-channel amplifier, look no further than GFA-555ms. The GFA-555ms 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. GFA-555ms is rated at 200 W into 4 ohms, takes both Unbalanced and Balanced inputs and provides high performance, ultra low distortion output power all from a neat package. We have engineered an uncompromised circuit design that delivers ultra-low distortion and a crisp dynamic sound. It all adds up to a startlingly vivid and highly impactful musical performance that will put more energy into your loudspeakers as well as control them like never before. Great care was taken to insure that distortion in the amplifier would remain extremely low, particularly when driving these highly reactive loads in which the phase angles of the voltage and the current are substantially different.
