User guide:

1) Connect the USB cable, turn on the power switch, the OLED display will light up. and it can be used immedately.

2) The differential output directly from the DAC has labelled with preallocated 2.54mm spacing socket for diyer easily connecting to their favorite IV and LPF and bypass the default onboard one. The onboard default opamp IV stage can be disconnected by removing the four  electrolytic capacitor. (Please test and enjoy the onboard default opamp output stage before any modification as it is tested to work and work great, modification can damage the dac easily)

FAQ:

1) Does the volume is controllable in Windows/MAC/Linux when playing DSD using this combo? I find that I cannot control the DSD volume when using the other famous brand DSD USB output adapter
The DSD sound volume is controllable using our xmos DSD combo in all USB audio 2.0 compatible OS including WINDOWS/MAC/LINUX system volume mixer.

2) Do I need to switch ASIO driver everytime when playing between PCM and DSD music file? I find it's annoying to do it when using the other famous brand DSD USB output adapter.
Our xmos combo can use the same output ASIO: foo_dsd_asio in foorbar2000 to play PCM and DSD music file. No need to go to foobar2000  preferences everytime to change the output device.

3) Some people told uses IIC software control can interference the DAC performance, is it true?
We do not know other design but our IIC volume control is only active when the user is moving the volume bar to change the volume, it is totally stopped when not in use. 

4) What sampling rate are supported?
PCM 44.1-768khz and DSD64 DSD128 DSD256 DSD512(native)

5) Any annoying pop sound when playing between PCM and DSD format?
No pop sound. The ES9038Q2M has automute feature when switch between pcm and dsd.

Design:

*Bit Perfect = audio data received by the dac chip is exactly the same as the song file from the computer harddisk.

To achieve it, either the user is playing at maximum volume, or doing the volume control inside the dac chip or after the dac chip(preamp analog volume control)
The only way to do volume control inside the dac chip is using mcu to control the dac volume register.(xmos flashed with our advance specific firmware can do it without extra mcu which causes unnecessary digital noise)

The common problem of most USB DAC in the market is separated the DAC volume control from the windows/mac/linux operation system mixer. i.e. The volume control on the DAC is not linked to the computer playback software. The original audio data will be changed again and again before the user can listen.

Most people may not notice many so called "bit-perfect" device on the market is bit-perfect ONLY when you playback at full volume. If the volume is not set to maximum in the computer, the audio data is scaled/altered/ruined before sending to the DAC chip and the result is signal to noise ratio seriously affected.

The XMOS in this USB audio DAC is flashed with our advance custom firmware, it can forward the user's volume control in windows or the physical volume encoder to the DAC internal volume register directly, and playback bit-perfect in any volume level.

*Rapidly switching the device off and on in succession can cause pop noise. After turn off the device, wait for at least two seconds before turn it on again

*This item is in limited stock, maximum one per buyer. Please contact us if you want to buy more than one, thanks
