This self-powered Class D amplifier module is set out to be an easily customizable full turnkey solution targeting the active 2-way PA speaker market. The heart of this solution is a purposely designed amplifier module which basically has all the bells and whistles on board to easily adapt it to the customer’s wishes without the need for a long and expensive custom development trajectory. It combines the switch mode power supply, two class D power amplifiers, a powerful Analog Devices ADAU1462 DSP supported by high-performance AKM Analog to Digital (AK5552VN) and Digital to Analog (AK4452VN) conversion stages and all the necessary analog circuitry optimized for best sonic performance possible on a single very compact PCBA. The customizing is basically done by means of the small input connector PCB together with the mechanics which still allows you to determine the layout of the connectors and controls, possibly additional input sources like microphone inputs, BT and even network audio, the control over the advancedness of the user interface (i.e. graphic display or simple LED indicators). This will enable you to keep control over the general look of your brand.

The very basic customer implementation like the one pictured above would be a single Line Input, a Link Output, a volume knob and some status LEDs for signaling Power, Signal and Limit requires no advanced electronics knowledge at all it is basically just connecting wires and you are all set to go. Because of the very versatile input section of the core module, even the most advanced functionality can be designed with the absolute minimum of effort.

The integrated high-performance DSP enables the user to easily implement custom filter algorithms and thus creating their sound signature without having to worry about the hardware or any interconnections. Just connect an input signal, be it analog, digital or even wireless, connect the loudspeakers and plug it into any mains in any country and PLAY! Simple as that!
