The DDX-2000 Controller includes two channels of DDX processing, digital volume control, mute and special processing to reduce distortion associated with signal clipping. The controller accepts standard PCM serial formats and operates from an external 256*Fs clock or from a crystal. The DDX-2060 Power Device is a dual channel Class-D H-Bridge power device that has a logic interface, integrated bridge driver, high efficiency MOSFET output transistors and protection circuitry. The benefits of this system are the all-digital design that eliminates the need for a digital to analog converter (DAC) and the high efficiency operation derived from the use of Apogee's patented damped ternary pulse width modulation (PWM). This approach provides an efficiency advantage over conventional Class-D designs and up to three times the efficiency of typical Class A/B amplifiers with music input signals.
