PRODUCT DESCRIPTION

The A4 series of amplifiers are power amplifiers for acoustic vibration applications with four in four out independent dual channel modes, each channel contains the power amplifier. The outstanding characteristics of the A4 series are the balance of input and output and the performance of high power/quality/trust/stability. The built-in protection circuit can automatically protect against overload, short circuit and overheating. In this case, the signal will be cut off and automatically restored.
