PX924为数字音频处理器，灵活组合的二输入四输出多种分频模式，可用作双通道的二分频、单通道二分频输出加二路超低音分频输出、单通道三分频输出加一路辅助分频输出、单通道四路分频输出的电子分频器。音箱控制器，亦可用作双通道的信号处理器。

PX924 is Digital audio system processor, neatly combining frequency dividing mode(2-input/4-output).For example,it can used as double channels 2-way output, single channel 2-way and 2-way subwoofer output, single channel 3-way output and 1-way accessorial across frequency output,single channel 4-way across frequency output Sound Electronic Frequency Divider. Sound box controller can used as double channels signal processor.
