At the request of the masses of users,after more than a year of efforts,we finally launched a quality very good independent external USB interface.The USB interface adopts Italian Amanero Combo384 solution,after Amanero license authorization,users are free to update the official firmware.
More critical of material selection,we use the highest rated at present,the price is also the most expensive American crystek CCHD-957 clock,to obtain precise digital audio signal reconstruction.Power supply side,the interface by a single 5V dc power supply,has carried on the multiplex branch power supply inside,each branch adopts TI import of ultra low noise TPS7A4700 independent power supply,the purpose is to the power of each part crosstalk noise to a minimum.(crystals also USES independent of a regulated power TPS7A4700)
All adopt the panasonic ultra low ESR solid-state capacitors and NPO/COG power steady flow and the optimization of ceramic capacitor of decoupling(remove high-frequency noise and improve the ability of the transient discharge).
Due to the interface without power supply,recommend users to use the linear power supply of the house:LPS-25-USB 5V Low noise output linear power supply(http://www.shenzhenaudio.com/l-k-s-audio-lps-25-usb-5v-output-low-noise-linear-power-supply.html)
Sound quality,and the overall sound like very stable,instrument body feels strong,sound quality and low-frequency descend with good cohesion,acoustic field is open, the sound fresh moist,full,connect fully, on both ends of the extension,sound density is wonderful,delicate and exquisite,balance and nature.
Drive and installation instructions(after open is copied to the browser,please download):http://www.mu-sound.com/about.asp?id=3
Computer USB connection,support for Windows XP,win7、win8、win10 system (32/64),support MAC system,support system of the Linux kernel,support most android,apple with OTG function system (in apple's camera suite connections)
Output coaxial mouth(support PCM 44.1K~192 K),coaxial without DoP output;
I2S output port(I2S-E) and I2S-H,support PCM44.1K~384K,DSD64~DSD512 native native DSD output,no signal DoP.
The white LED display,can display the current work of the sampling rate.
