professional power amplifier ca, power amp pro sound

CA 18 power amplifier features:                                                                                                        
1.This CA Series Power Amplifier is H Class circuit.
2.It is a circuit between the digital amplifier and traditional amplifier.
3.And it's designed according to the professional HI-FI(high fidelity) standard.
4.There're two groups of high-power tube installed on both sides, in order to enhance the cooling efficiency.
5.The amp is elaborated by the imported Japanese original Toshiba tube and Japanese original ELNA   capacitor, which is also used by the US GM company, for expanding flow output.
6.H class circuit is a kind of fast recovery circuit which is equipped with high efficiency intelligent cold system,    DC protection, short circuit protection, overheating and overload protection,ect. It can working at 2 Ohms stably for a long time.
7.The amp also makes the sound of speakers to be wide field, structured, thin, clear,uninhibited, glossy, good texture, perfect fitting the high-end speakers.
