VT1705

VIA Vinyl HD Audio codecs represent the next generation of sound quality, supporting the high definition HD Audio standard for a whole new immersive surround sound experience. The VIA Vinyl VT1705 is a low-power optimized, high fidelity, 6-channel High Definition audio codec which is compatible with Intel® High Definition Audio specification and supports stereo 24-bit resolution and up to 192 kHz sample rate for DACs/ADCs.

The VIA Vinyl VT1705 features three high performance stereo DACs, two stereo ADCs, analog input to analog output mixing, and two independent S/PDIF outputs. It can achieve 100dB Signal-to-Noise Ratio (SNR) for DACs and 93 dB SNR for ADCs. A high quality analog mixer is used to support A-A path.

The VIA Vinyl VT1705 features three built-in headphone amplifiers and analog microphone with four sets of adjustable Vref-out pins for microphone bias. The stereo ADCs and microphone array can support Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) technologies for an unmatched PC audio experience.

The VIA Vinyl VT1705 uses two jack detection pins for presence detection on up to eight audio jacks allowing software to determine if there is a device plugged into the circuit. It also boasts a front-panel jack re-tasking feature that allows flexible configurations.

The VIA Vinyl VT1705 is embedded with software utilities such as environment emulation, EQ, extender, and optional sound effects, including support for QSound, DTS Connect, DTS Surround Sensation, Dolby PCEE program, Creative Audio Program and Third Party Microphone Array Technology.
