A-36 Stereo Power Amplifier

Description

A-36

Impressive pure class A stereo power amplifier redefines baseline excellence — The A-36 inherits many of the outstanding design technology features developed for higher-end models such as the A-200 and A-70. It redefines the basics for pure class A power amplifiers and has been carefully honed with the same unwavering attention to detail and dedication to sound quality for which Accuphase is famous. Power MOS-FET devices in triple-parallel push-pull configuration for each channel, fully balanced signal paths realized with instrumentation amplifier topology, along with MCS+ design and current feedback in amplification circuitry deliver outstanding performance for improved sound quality. The robust power supply easily sustains power output of 150 watts per channel (music signals) down to impedances as low as 1 ohm, and bridged mode turns the unit into a superlative monophonic power amplifier with even higher output. In the output circuitry, MOS-FET switches used in place of relays eliminate mechanical contacts and help to improve long-term reliability. Top-grade materials and sophisticated circuit pattern technology result in low impedance and allow the realization of a damping factor of 400.
