产品概述
HFA-500M 单声道后级
The HFA-500M is a single channel amplifier for listeners who want one chassis per speaker. The narrow 200 mm chassis makes it easy to place close to the loudspeaker and keep speaker cables short.
Power supply capacitance is 80 000 uF with a 1000 VA transformer. The output stage runs on plus/minus 95 V rails and is protected by a DC servo and a relay that disconnects the loudspeaker within 200 ms of a fault.
