GFA-555ms – Finale di potenza

Dedicato a coloro che cercano un finale compatto nelle dimensioni ma generoso nelle prestazioni.

Il finale di potenza GFA-555ms pilota con disinvoltura una gran varietà di diffusori, inclusi quelli a bassa impedenza.

Fornendo sempre un’abbondante riserva di potenza, unita d una timbrica neutra ed equilibrata.


Dynamic Sound

GFA-555ms runs on 200 W into 4 ohms, takes both Unbalanced inputs and drives your speakers with 125 x 2ch  Watts of high performance, ultra low distortion power output 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.


Low Distortion

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 voltageand the current are substantially different.
