The IIC volume control is only active when you moving the volume bar to change the volume, it is totally stopped when not in use.ħ)Any annoying pop sound when playing between PCM and DSD format?
#Dac cirrus logic cs4398 software
The circuit mostly follows the official datasheet, it can be download from the related official DAC website.ĬS4398 : 120 dB, 24-Bit, 192 kHz Stereo D/A Converter with DSD Supportĥ)Some people told uses IIC software control can interference the DAC performance, is it true? The XMOS PCB in this combo is designed only for use in this combo. No need to switch output everytime to play.ģ)Is the xmos i2s Bit-perfect volume control PCB in the combo can be used connect to other DAC chip?ĭifferent DAC chip require different IIC volume control command and different DSD PCM switch command. Our xmos combo can use the same output ASIO: foo_dsd_asio in foorbar2000 to play PCM and DSD music file.
#Dac cirrus logic cs4398 driver
The DSD sound volume is controlable using our xmos DSD combo in all USB audio 2.0 compatible OS including WIN/MAC/LINUX system volume mixer.Ģ) 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. This is the initial prototype, the cs4398 DAC PCB will be in yellow color, the final layout will have a little different from the photoġ)Does the volume is controlable in WIN/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

#Dac cirrus logic cs4398 full
Please notes there are many so called bit-perfect device can play DSD but you must set the computer master volume control to full volume. DSD audio as well as PCM audio can also be bit perfect volume control easily from the computer. This USB DSD DAC: Complete Bit-perfect at any volumeĬomputer -> USB -> XMOS -> I2S(audio data bit perfect at any volume)+IIC volume control -> DAC Chip (es9018/cs4398/pcm1794 etc.)Īfter many hours of work on customize the xmos firmware on this USB DSD DAC, audiophiles can move the volume control bar up and down freely in the computer volume mixer panel and still enjoy bit perfect audio. General device on the market: "Partial" Bit-perfect only at full volumeĬomputer -> USB -> XMOS/CMxxxx/AMxxxxx -> I2S(audio data scaled/altered if not at full volume) -> DAC Chip (es9018/cs4398/pcm1794 etc.)

If the volume is not set to maximum in the computer, the audio data is scaled/altered before sending to the DAC chip and the result is signal to noise ratio seriously affected. Most people may not notice many so called "bit-perfect" device on the market is bit-perfect ONLY When You Play At FULL Volume. The most distinctive features of this USB DSD DAC is our customize firmware for bit-perfect volume control. This USB DSD DAC contains two main PCBs, XMOS USB to I2S with three ultra low phase noise NDK2520SD oscillator PCB, CS4398 DSD DAC PCB and an optional LED sampling rate indicator PCB.Īpart from the DSD playback functionality, it uses low noise thin film resistor, C0G capactor in the LPF, WIMA decouple cap, panasonic low ESR aluminum electrolytic capacitor and optimized layout 2mm distance for all decouple capacitor, etc. Low cost is not equal to low quality components Low cost USB "DSD" DAC with bit-perfect volume control GB
