Looking for who said what in the sound world? Well there is no better place to find every audio related press release than 3DsoundSurge.!

``With the development of multi-channel home theater audio and the proliferation of digital audio recording and transmission standards, electronic manufacturers are driven towards all-digital high efficiency amplifier designs. The DDX-2000 meets this technical and marketing challenge by enabling 100% digital sound reproduction while at the same time reducing amplifier size and power supply cost,'' said David Meyers, Apogee's Vice President Business Development.

The DDX-2000 is the first in a series of DDX semiconductor products planned by Apogee. The design includes two channels of DDX processing, digital volume/gain control, automatic mute and specialized processing to reduce distortion associated with signal clipping.

The device can be combined with discrete power circuitry to produce an all-digital amplifier that can provide over 100 watts of audio power at very high efficiency. For lower power applications, Apogee plans to offer a companion 30-watt per channel integrated power device.

The company has completed engineering samples of the DDX-2000 and plans to be shipping production quantities in December. Samples of the integrated power device are expected to be released during the fourth quarter of 2000. The company is also marketing its DDX Controller core product for semiconductor companies wishing to add DDX functionality to custom digital or mixed signal ASICs.

DDX Technology

Existing digital audio products use analog amplifiers to amplify analog signals produced by a digital audio converter, or a DAC. The problem with this approach is that the digital signals require conversion and analog amplifiers waste most of their power as heat. This poor efficiency means higher power supply costs and increased product size due to the need for large heat sink to dissipate the amplifiers wasted power. DDX eliminates the DAC by integrating this functionality - along with the power amplifier control - into a fully digital process, or Controller. The Controller converts audio data into digital signals that directly control high-efficiency power transistors. This approach eliminates analog noise problems and increases power efficiency by a factor three compared with traditional analog designs playing music.
