|Adcom GFA-555 II Amplifier|
|Category||Audio Video TV Multimedia|
The Adcom GFA-555D is a stereo power Amplifier rated at less than 0.04% THD from 20Hz to 20kHz with 200 watts into 8 ohms and 325 watts into 4 ohms. The output stage Is capable of greater than 60 amps into low impedance loads. The Amplifier employs a discrete differential Class-A front* end followed by a Class-A voltage gain stage which amplify the input signal to the voltage required at the output of the amplifier. This high-voltage signal drives the high-current triple-Darlington-follower output stage which amplifies the current by a factor of about 50,000.
