ACCUPHASE A200

CLASS-A MONOPHONIC POWER AMPLIFIER

The A-200 encompasses Accuphase power amplifier know-how to the fullest. It is destined to become another milestone, taking the art of audio to the next level. In order to realize ideal speaker drive capability, the A-200 employs a structural design that exceeds even the M-6000. Two completely separate power amplifier units, each with its own dedicated heat sink on either side of the chassis, are driven in parallel.

• Pure Class A operation delivers 100 watts of quality power into 8 ohms 
• Two totally identical power amplifier units driven in parallel 
• 20-parallel push-pull arrangement of MOS-FET devices in output stage delivers linear high power progression to ultra-low 1-ohm impedance 
• Input section configured as double instrumentation amplifier 
• Double MCS+ circuit and current feedback topology in amplification stage 
• Support for bridged use of two A-200 units with even higher output power 
• Strong power supply with massive high-efficiency toroidal transformer and large filtering capacitors
