Product Details:
A9.4 adopts a fully symmetrical X-Amp ultra fast fully DC coupled power amplifier circuit, which can balance signal or single ended signal input Featuring high damping, it can drive all low sensitivity large speakers Rigorous sound, high resolution, first-class control, excellent low frequency.
1:) Super large and thick all aluminum chassis Good heat dissipation effect.
2:) Two 600W Nippon Steel transformers provide independent power supply for the left and right channels.
3:) 8 pieces of 10000uF audio electrolysis per channel.
4:) The left and right channels are designed to be completely independent, with the amplifier board, power board, and protection board completely separated from each other.
5:) Each channel has 7 pairs of precision paired Japanese made genuine Sanken transistors.
6:)Each transistor has a maximum static current of 300mA.
7:) A comprehensive speaker protection circuit effectively protects your expensive speaker.
8:) Equipped with startup soft start and power DC filtering function
9:) A9.4 adopts single crystal copper signal cable
