Crest style CA Series Professional Power Amplifiers
PRODUCT DESCRIPTION:                                                                                                            
--This CA Series Power Amplifier is H Class circuit.
--It is a circuit between the digital amplifier and traditional amplifier.
--And it's designed according to the professional HI-FI(high fidelity) standard.
--There're two groups of high-power tube installed on both sides, in order to enhance the cooling efficiency.
--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.
--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.
--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.
