产品概述
HFA-2500 立体声功放
The HFA-2500 doubles the output stage of the HFA-1200 and raises the supply to plus/minus 82 V. It delivers 250 W per channel into 8 Ohm and stays stable into 2 Ohm loads.
A temperature controlled fan engages only above 45 degrees Celsius, so the amplifier is silent in normal listening. Biasing is set per channel and can be re-adjusted through the top panel without removing the board.
