Description

The DDX-8229 Controller provides a combination of standard PWM and DDX® outputs and a complete set of digital audio preamplifier functions.

The DDX-8229 is a single chip solution for digital audio processing and digital amplifier control, featuring output capabilities for DDX® (Direct Digital Amplification). In conjunction with a DDX® power device, it provides highquality, high-efficiency, all digital amplification. The device is extremely versatile allowing for input of nearly all digital formats including 6.1/7.1 channel, 192kHz/24- bit DVD-Audio, and SACD. In 5.1 applications the additional two channels can be used for line-out or headphone drive.

Also provided in the DDX-8229 are a full assortment of digital processing features. This includes up to 10 programmable 32-bit biquads (EQ) per channel, bass/treble tone control, and dual 8-input mixing blocks per channel. Automode™ technology enables a timeto- market advantage by substantially reducing the amount of software development needed for certain functions. This includes all possible 5.1 bass management configurations with simple large, small, and off control settings. New advanced AM radio mode solves one of the most common concerns using switching power amplifiers.


The DDX-8229 is a 4th generation DDX®/Binary PWM controller and is uniquely suited for the most demanding applications, providing an audiophile experience without parallel.
