Power amplifier GFA-555ms

For those who desire the delicacy of power. In a two-channel amplifier, look no further than the GFA-555ms. The GFA-555ms amplifier can drive a wide range of loudspeakers, including those with very low impedances, at sustained high power levels, even when the impedances are highly reactive. GFA-555ms runs 200W into 4 ohms, takes unbalanced and balanced inputs, and powers your speakers with 40+40 watts of ultra-low distortion, high output power output, all from one neat package. We've engineered an uncompromising circuit design that delivers ultra-low distortion and clear dynamic sound. It all adds up to a surprisingly vivid and highly impactful musical performance that will put more power into your speakers and control them like never before.

low distortion

Great care was taken to ensure that distortion in the amplifier
remain extremely low, particularly when driving these highly reactive loads where the phase angles of voltage and current are substantially different. PZA More features
