Digital Audio Processor
1.0 GENERAL DESCRIPTION
The DDX-8001 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 high-
quality, 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-8001 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.
Automodes™ enable a time-to-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/off
control settings. New advanced AM radio mode solves one
of the most common concerns using switching power
amplifiers.
The serial audio data input and output interfaces accept all
possible formats, including the popular I2S format. Eight
channels of DDX® processing are provided with capabilities
of controlling the output switching frequency or modulation.
This high quality conversion from PCM audio to DDX’s
patented tri-state PWM switching waveform provides over
100dB SNR and dynamic range.
The DDX-8001 is a 4th generation DDX® controller and is
uniquely suited for the most demanding applications,
providing an audiophile experience without parallel.
Specifications are subject to change without notice.
