CMD-2 Dual CS43198 Balanced DAC DSD256 Bluetooth 5.0 Headphone Amp + PW-06 Precision Dual Supply

Attention:
- User manual is not included.
- The Bluetooth antenna can be installed on the antenna socket, and it does not need to be tightened, otherwise it may drive the wire inside the base to rotate and cause the wire to break and fail to receive signals.

Description:
Dual parallel CS43198 decoder, split power supply, mini desktop all-in-one machine.

Compared with chips for ESXXXX and AKM, the sound of CS43198 has a thick sound bottom and three-stage balance. It does not have the feeling that the two ends of the ES series chips are tilted and the intermediate frequency is relatively thin. The split power supply design can greatly reduce the interference of the power supply to the analog circuit.

The DAC decoder adopts dual CS43198 decoding chip design, supports 5 kinds of audio input, has complete functions, convenient power supply, and the sound quality is not inferior to large desktop computers. The chip for XMOS XU208 is used as a USB interface, and with MCU control, it can play PCM, DSD64, DSD128, DSD256 format music (DSD256 adopts native playing). With linear line out output, balanced XLR output, balanced amp output.

The Bluetooth chip is currently the best sound quality British CSR8675, supports Bluetooth 5.0 protocol, supports for CD-level sound quality transmission protocol ATTX and APTX-HD, LDAC, the module is a firmware optimized for music playing, this DAC directly decodes the IIS digital signal of CSR8675, and Instead of using its internal DAC, it can greatly improve the sound quality! Note that there is no call function. The Bluetooth receiving distance is about 10 meters, and partition walls and obstacles are not supported.

Precautions:
1. Recognization for XMO SUSB is disabled after it is connected to a computer. In this case, it may be caused by the USB cable, poor contact of the USB port, or USB cable problems. Please troubleshoot the USB cable and socket problems.
2. When the USB port of this machine is connected to the USB port on the front of a desktop computer via a USB cable, it may cause popping noises during playing.
3. If you switch to another power supply, the voltage must be between ±12V and ±13.5V, and the current is 3A. Exceeding the voltage will cause damage.
4. If you find that the Bluetooth device cannot be paired, please turn off the DAC for 1 minute and then turn it on again to pair.
5. For FOOBAR will monopolize the device for XMOS when playing. At this time, other software is not allowed to sound. If you want to use other software, you can only stop or close that for FOOABR, and set for XMOS XS1-U8 DJ (ST) as the default device. (You can also cancel the exclusive use in the properties for XMOS)
6. There is only mono channel during Bluetooth playback. In this case, the LHDC function (Haiby Player) is generally turned on. Because this Bluetooth supports for LDAC, it does not support LHDC, and there will be conflicts, so turning off the LHDC function is normal.
9. The balance port of some back-end equipment is not really balanced (the internal cold end is grounded or converted to single-ended with an op amp) and there may be background noise.
10. Some people think that the DC line connection is unreasonable and put the power supply case upside down, which will cause hum.
