·The orginal Audio power amplifier C98392-A9701-A442 is no longer produced. The amplifier is  expensive and it is hard to find supplier.  But owing to the sorting of the interface in the  voice cabinet equipment, the amplifier can not be replaced by the other power amplifier on the market.  Therefore, we designed and developed new interface board.
