Freeshipping F139# USB Digital Sound Card DAC USB Switch Coaxial Support AC3 DTS 5.1 TDA1305T Decoder

Product Description

Multifunction USB sound card, built-in TDA1305T decoding to analog audio output, the maximum output power of 60MW, you can directly drive headphones. With fiber coaxial digital output, external decoder, amplifier. And support for AC3, DTS multi-channel source output. Easy to make laptop 5.1 home theater features!

USB decoder chip decode information in Taiwan's Hua CM108. It not only supports USB2.0 high-speed transmission, but also with the I2S output, which is the main reason we chose it. DAC decoding using the famous Philips TDA1305T chip. The chip in a very good sound quality and well-known by some foreign power amplifier manufacturers widely used. The decoder gives them a perfect combination of the CM108 by I2S digital signals transmitted directly to the TDA1305T, and do not use SPDIF transmission. Only twice more with SPDIF conversion, but also through the PLL phase-locked loop, jitter increases a lot. I2S direct transfer but also by a number of low-frequency to be thick. In terms of power output is not small, to promote the general sound of 32 European low-impedance headphones are very large.


In the power supply filtering, audio and other important parts coupled with the Japanese ELNA, nichicon and other special audio capacitors. Make the power more pure, more natural sound. And are used by 1% metal film resistors. And use the active crystal, greatly improving the stability of the circuit.

USB digital output, high-speed 2.0 transmission. Support APE, FLAC and other lossless music. And support AC3, DTS5.1 other multi-channel source output. AC-3, DTS-DVD, DTS-CD, DTS-ES6.1 so perfect support! And both support WINDOWS XP, VISTA, WIN7 system.
