Overview
STA306 MULTICHANNEL DIGITAL AUDIO PROCESSOR WITH DDX™ PRODUCT PREVIEW s s 6 DDXTM Channels Capability (24 bit) From 32kHz to 192kHz Input Sample Rates Supported Volume Control from 0 to -127 dB (0.
5 dB steps) Variable Digital Gain from 0 to 24dB (0.
5dB steps) with Digital Limiter Functionality and Variable Attack and Release Time I2S Inputs and Outputs Individual Channel and Master Gain/ Attenuation Individual Channel Mute and Zero Input Detect Auto-Mute Selectable Serial Audio Data Interface Bass/Treble Controls Channel Mapping of any Input to any Processing/DDXTM Channel Active Crossover Capability DC Blocking Selectable High-Pass Filter Selectable Bass Management on Channel 6 Selectable Adjacent Channel Mixing Capability Selectable Clock Input Ratio Selectable De-emphasis Selectable DDXTM Ternary, or Binary PWM output AM Interference Reduction Mode I2C Control DESCRIPTION The STA306 is a single chip solution for digital audio processing and control in multi-channel applications.
It provides output capabilities for DDXTM (Direct Digital Amplification).
In conjunction with a DDXTM power device, it provides high-quality, high-efficiency, all digital amplification.
The device is extremely versatile allowing for input of most digital formats including 192kHz, 24-bit DVD-Audio.
The internal 24-bit DSP allows for high resolution processing at all standard input sample frequencies.
Processing includes volume control, filtering, bass management, gain compression/limiting and PCM and DDXTM outputs.
Filtering includes five user-programmable 28-bit biquads for EQ per channel, as well as bass, treble and DC blocking.
External clocking can be provided at 4 different ratios of the input sample frequency.
All sample frequencies are upsampled for processing.
Each internal processing channel can receive any input channel, allowing flexibility and the ability to perform active digital crossover for powered loudspeaker systems.
The serial audio data interface accepts many different...
