Specific characteristics:
humanized appearance design process :
chassis designed and manufactured from aluminum alloy ;
beautifully elegant arc linear process modeling ;
Blu-ray tubes with affinity set off display ;
elegant and compact size .
a variety of input options: analog line signal Line input and USB digital signal input selection , you can easily select the desired input mode ;
Main volume adjustment, can make you get the desired sound effect .
Headphone output jack : 3.5mm and 6.35mm jack dual parallel output options , allowing you to easily fit different plugs headphones available in the market ;
Headphone output A and B are parallel output, stereo headphone signal, the output impedance is 10Ω;
A or B alone headphone output adaptation of minimum impedance 8Ω, A and B, the lowest total impedance of the parallel output 8Ω;
Headphone output impedance adaptation range 8-1000Ω, the output power peak - range 2.7W-100mW, strong thrust , can easily drive all the headphones, the first truly able to fully fit the market all headphones amp ;
For increased headphone output jack, you can use a standard of a "Y" adapter plug assign the two headphone output jack.

DAC Decoder:
24-Bit Dac Usb decoder , using Micronas UAC3553B high quality decoder integrated chip, support the highest rate 48KHZ output of the decoder chip wide frequency response , high resolution
24-Bit Dac Usb decoder connected to the computer , the computer can decode lossless high-fidelity music playback ;
Up Support 24-Bit audio playback , the conversion rate for the 6.4-48KHz;
Usb 2.0 ports, stereo audio D / A decoding.

Power Stage Design:
The wide frequency response , low distortion, high fidelity amp TI TPA6120A2 top integrated IC design ;
Dual voltage power supply design for the positive and negative power supply , because dual voltage power supply, so the power output dynamic range, wide frequency response , low distortion , driving ability ;
Output impedance is 8Ω, adaptation impedance range of 8-1000Ω;
1000Ω load output 100mW strong driving force , 300Ω load, a strong driving force output of 350mW , easily drive the market 300-1000Ω impedance headphones ;
8Ω load of about 2.7W per channel power output , not only can push a good low-impedance headphones , but also be able to easily push below 10W speakers, so the machine has a dedicated connection speaker Spk-Out RCA stereo output jacks ;
The output of smaller distortion , very low noise (<0.1mV noise , SNR> = 90dB) and wide frequency response , so the machine can be used to make high-fidelity preamp from Spk-Out 's RCA jack stereo output signal, the tube amplification, access to other audio device can enhance the sound quality of the output of the device .

The machine features elegant selection :
Power switch and input selector switch imported from abroad , the mechanical contact performance and long service life ;
selection of Japanese ALPS potentiometer imported good contact performance , low noise , small error and long service life ;
In addition to the two non- electrolytic capacitors monolithic capacitors , the rest all made of high quality German WIMA capacitors ;
105 ℃ electrolytic capacitor full selection of high-quality audio English NOVER electrolytic capacitors , high temperature , strong reliability , quality is stable and reliable ;
1/6W full precision 1% resistors , so that the machine sensitivity, precision, drift work to ensure that every machine factory and design consistent with the requirements ;
RCA jack , 3.5mm and 6.35mm socket contact terminals gold-plated , easily oxidized , to ensure good contact with the machine performance
