power amplifier








Aluminum alloy case makes lighter weight
There are frequency divider circuit, card insertion, frequency division filter for octave 24dB, Linkwitz, Riley design
With perfect DC, short circuit, overheat protection circuit, when the fault disappears, the system will be restored automatically
Unique current drive, power output stage design, so that the performance of sound quality is more transparent and delicate
