The latest version of the USB interface is a micro usb, almost every mobile phones are now this interface
PCM2706 + TDA1305DAC decoder, USB sound card, HIFI amp, laptop integrated sound card upgrade (USB powered, no external power supply) do not to compare with CM108, it is not same thing.
Output selection switch,
Select the analog and digital outputs, switch to the USB interface is the analog output, which in turn is a digital output.
2013.10.06 latest upgrade, change the output system, the bass power enough. Using active crystal, higher precision, more accurate sound, stronger anti-interference. The effect is much better than before. Let the music richer musical taste, sound quality than the previous version improved a lot. Slim version.(HIFI EXQUIS)
After repeated listening and improvement, finalized version of the in-kind shooting, selected materials. Digital and analog sections to isolate,
Secondary isolation to reduce interference pass over the computer.(HIFI EXQUIS)
DAC output section tough materials, according to the working characteristics TDA1305, with the material after repeated screening,(HIFI EXQUIS)using a 1% precision ERO capacitance, capacitance poor accuracy is not so good sound quality. The output capacitor is very important, the output capacitor with a Weimaraner, ELNA STARGET dedicated audio capacitors. Weimaraner, ELNAS STARGET mixed in the audio industry is very good, oh, play sound knows its toxicity. Filter using ELNA, rubies, King Kong and other capacitors.
USB chip uses pcm2706(HIFI EXQUIS), with the I2S output, which is the best transmisssion mode , the best sound quality . They are able to take full advantage of the potential TDA1305 . This is the main reason why we chose it .(HIFI EXQUIS)DAC decoding part with a famous Philip TDA1305T chip. Transparent and pure sound , background quiet , high-frequency extension and air feeling good, listen to the human voice was captivating voice reduction , bass produce a comfortable sense of encirclement , fast , very stable and clear . The chips were very good sound quality of some well-known foreign manufacturers amplifier widely used. The decoder gave them a perfect fit , the digital signal is transmitted directly to the TDA1305T by I2S, SPDIF transmisssion does not use . Not only twice more with SPDIF converter , but also through the PLL , jitter increases a lot.(HIFI EXQUIS)
High resolution , bass is very flexible, dynamic and very full, beautiful tone , the sound is very clean and pure. Usually listen to the voice saliva song , strings piano or something, I believe it can meet you and give you a surprise : so small , inexpensive DAC actually have such good sound quality!(HIFI EXQUIS)
Variety hifi amp used TDA1305 DAC decoding chip as :
CAMBRIDGE AUDIO CD6 TDA1305T CYRUS dAD3 TDA1305
MICROMEGA STAGE6 TDA1305 MIS-SION dAD3 TDA1305
NAIM AUDIO CD3.5 TDA1305 NAIM AUDIO CD5 TDA1305
PINK TRIANGLE NUMERAL TDA1305T ROKSAN CASPIAN TDA1305ROTEL RCD-970BX TDA1305T(HIFI EXQUIS)
ROTEL RCD-975 TDA1305T
Input interface for the USB port , connect the computer directly and automatically install the driver after the driver is installed, the original sound is masked, very easy to use .
Output interface for the two 3.5mm jack , reliable contact. A hole can be connected via 3.5 to RCA signal line to the pre- amplifier , the addition of a hole you can plug headphones while listening , convenient and practical.
Output level : 1.5V RMS(HIFI EXQUIS)
Note: The volume is in the computer ( audio player ) adjustments, the volume down when using headphones to prevent damage to the headphones !(HIFI EXQUIS)
Troubleshooting: USB accept the chip vulnerable due to outside interference , when the frequent use of high-power electrical or electromagnetic radiation with relatively large appliances , sometimes resulting in G2 is not working properly : silent or noisy , this is generally the USB cord such as 3-5 seconds and then plug in to normal .(HIFI EXQUIS)
PCB board size: 80 × 49.5MM
