PMA-540 Direct A, Real Drive Circuit - Integrated Amplifier
Non-switching power amplifier delivers 60 W + 60 W power output
Super equalizer amplifier provides a wide RIAA deviation from 20 Hz - 100 kHz ±0,2 dB
Real drive circuit reduces distortion during speaker drive by 1/50
Newly developed real time tone control circuit prevents deterioration in sound quality
Provided with A, B speaker system for individual On Off switch.
