STA311B

Multichannel digital audio processor with FFX
  • active Active

The STA311B is a single-chip solution for digital audio processing and control in multichannel applications and provides output capabilities for FFX™ (full flexible amplification). In conjunction with an FFX™ power device, it provides high-quality, high-efficiency, all digital amplification. The device is extremely versatile, allowing for input of most digital formats including 6.1/7.1-channel and 192 kHz, 24-bit DVD-audio, DSD/SACD. In the 5.1 application the additional 2 channels can be used for audio line-out or headphone drive.
