Muse B1 Decoder Board USB/Fiber/Coaxial/Analog Input Amp Sound Decoder DAC Board PCM1793

Muse MINI USB DAC MK2 is designed for music-loving customers to design a collection of USB sound card, DAC decoder, OP + BUF framework bile taste amp as one of the new high-quality product! MINI USB DAC MK2 sound compared to traditional independent soundcard, has a greater range and better portability and the whole process did not penetrate electromagnetic interference, they are able to provide pure angelic voice! 

1.The main capacitor using a Philips BT series, beyond the hard cold style Japanese, bringing Rounuan effect Europe 

2.Preparation of plates specially designed power switch 

 

Mini USB DAC Functions: 

1.when the high-end external USB sound card to use, because an external sound card with an external power supply, thus avoiding interference of the PC switching power supply. Make the sound more pure, Naiting. 

2.high-grade DAC decoder uses, using American audio company (BB) of the PCM1793 special decoder chip, the sound quality can be achieved quality finished CD player. 

3.high-end amp independently, behind the product has analog audio input can be directly connected to the high-end analog audio source, promote your beloved hifi headphones, allowing you to enjoy the sounds of nature music. 

 

Product Use:

To the decoder as the center, the radius of other products, as long as you use any of a match, can get a good music experience, multi-function, multi-angle, small size, can be described as eye candy! 

 

MK2 and cd machine, combined with the use of laptop computers, headphones can achieve very good results, Vertical & Horizontal well suited to your home environment, perfect for listening to music with your environment! 

 

MINI USB DAC MK2 support computers play lossless APE, FLAC format files, perfect support 24bit bit rate S / PDIF coaxial and optical input section, this approach is the most widely used application, if from the Internet for lossless APE, FLAC formats, will not need to purchase and organize complex CD discs 

 

But more importantly, he is a high-quality amp! 

 

Specific Features: 

1."USB sound card scheme" native computerized voice signal is received by Texas Instruments part of PCM2707. Computer through the USB interface to receive signals directly I2S output for sound decoding with TI produced by DAC chip PCM1793, expanding output through LineOut or ear sound! Than the market in general SOUND CARD or USB SOUND using the chip for decoding the original, there is a better performance on the sound! 

 

2."DAC program" The machine has Coaxial (Coaxial) and optical digital inputs, through more than CS8414, CS8412CP better DIR9001 (TI produced) digital receiver chip, the receiver is connected CD / DVD devices via coaxial digital signals can be decoded by the sound of the machine DAC chip PCM1793, the general CD / DVD turntable voice visibly improve! And the same can be connected through LineOut output to an external speaker or headphone output to expand through the ear to enjoy music. 

 

3."headphone amplifier (Headphone Amp) program" native ear ear expansion SOLO part reference line expand and make improvements, in addition to the sound card can be used, DAC ear expansion, but also add a lot of equipment. The machine uses a dedicated signal relay Omron (Relay) for signal set to change, external analog inputs (Analog) signal through Line In (RCA terminal block)! Such as sound CD / DVD machine output, the existing DAC's analog signal, even IPod sound output (requires adapter via Lineout output signal)! And when users provide a better power supply, the machine ear expansion will further enhance the sound! And this machine ear expansion of the op amp (OP) use DIP package, users can put on their own each other OP adjust sound ornaments, even a lot of high-end sound card, use the patch package OP, can not be replaced! 

 

4.The machine uses a dedicated audio power amplifier as the core of a single turn double IC, USB machine and a CD of similar size, easy to carry! And you can add high-capacity batteries for power! 

 

5.The machine sounds direction, drawing tube USB DAC design experience, using a variety of advanced headphones actually adjust the sound to further enhance the sound quality! 

 

6.The machine as in the past, with high-quality components required to configure, use Nichicon, EVOX, RIFA capacitor, KOA resistance, NEC relay and high-quality potentiometers and other special units produced audio components 

 

7.The MINI USB uses a special new element! TI is produced DIR9001, which is a digital receiver chip, the role and CS8414, CS8412CP like! Handled properly, the sound was much better than the previous two! There are many places abroad, has made DIR9001 replace CS8412CP module, this module alone, the price has been close to 200! 

 

8.Volume: 165mm × 135mm × 61mm
