Computer decoding amp USB external sound card PCM2706 TDA1305 can be analog, digital output
- New with analog audio output and digital audio output modes , there switch to select analog and digital . Oh, but also with volume control ( easier to control large and small volume )
- PCM2706+ TDA1305DAC decoder HIFI amp laptop USB sound card integrated sound card upgrade(USB -powered , no external power supply )
- USB data cable is male to male USB cable
- After repeated listening and improvement , finalized version of the in-kind shooting , selected materials . Digital and analog portions isolate secondary isolation to reduce interference pass over the computer .
- DACThe output section tough materials, according to the working characteristics TDA1305 , using material after repeated screening, with a strong industrial Siemens capacitor , Philips CBB capacitor , the output capacitor is very important , the output capacitor with aELNA audio capacitors. ELNAIn the audio industry mix very well , oh , play sound knows its toxicity.
- USB chip uses pcm2706, with the I2S output, which is ideal for transportWay , the best sound quality . They are able to take full advantage of the potential TDA1305 . This is the main reason why we chose it . DAC decoding part with a famous Philips TDA1305 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 TDA1305 via I2S, SPDIF transmission does not use . Not only twice more with SPDIF converter , but also through the PLL , jitter increases a lot.
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 !
- 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 is a 3.5mm jack , the switch to switch analog signals, digital signal output.
- You can plug headphones listening machine , can also be connected to the front stage , the use of amplifiers.
- Finished machine ultra-small , ultra-thin volume : 75 * 75 *22MM
- Board body volume : 67 * 65 * 16MM
- Output level : 1.5V RMS
- Note: The volume can be a computer ( audio player ) adjustment can also be adjusted in the above machine , please put down the volume when you plug headphones to prevent damage to the headphones !
- 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 .
