Download and install the official WASAPI output plug-in for Foobar2000ģ. Download and install the latest version of Foobar2000 from the official website (the latest version tested to work is v1.6.10)Ģ. *The I2S data output from XMOS is always 32bit(BCLK/LRCK/2=32), the USB audio data received from computer can be 16bit, 24bit or 32bit.ĭSD playback steps using foobar2000 in Microsoft Windows 10 default inbox driver(no extra driver installation) 202203:ġ. Please check your DAC should support the following I2S signal specification to decode each sampling rate: DATA *DSD256 only support in native mode (for windows requires >=v3 driver version) *No driver installation is required for Linux with UAC2 compliant kernel *No driver is needed for MAC OS version 10.6.4 and above OLED display is the latest technology with highest contrast, complete dark background, full viewing angle and it looks much better than the commonly used LCD displayħ) Sampling rate can be displayed on the 14x LED PCBĩ) PCB is powered by external 3.3V 800mA regulated supply on the white JST-XH 2pin 2.54mm spacing socket, it is usually connected to the same 3.3v digital power DAC is using(warning: over-voltage or reverse-voltage can damage the xmos chip immediately, double check before power on) I2S input and output is working at the same sampling rate.ģ) 4 layer gold plated PCB, Solid ground plane (a must for high speed digital circuit)Ĥ) NDK NZ2520SDA Ultra low phase noise oscillator and Murata capacitor sourced from Japan directly (guarantee no fake product from China)Īccording to the official datasheet, the phase noise of NZ2520SD is much better than the famous crystek 957 under 25khz(human listenable range)įor easier comparsion(lower is better), we overlay the two phase noise graph at the same scale, under 25khz(human listenable range) nz2520sd(red line) is better, over 25khz(human unlistenable range) crystek 957 is better.ĥ) No switch mode power supplies in the PCBĦ) Sampling rate and bits depth is displayed directly on the 128圆4 OLED panel. Asynchronous reclock usb audio data to I2S signal for all the modern DAC standard input.Ģ) Support upto 32bit 384kHz 2 channel input and 2 channel output or DSD256(native) two channel output. The latest xmos xCORE-200 includes unique hardware divider and it is used to generate the I2S bit-clock from the oscillator directly(old xmos BGA U8 uses software divider). But XU216 pcb with the full feature version driver still sound better in EMI noise environment technically.ġ) XMOS XCORE-200 XU208 with 1 Tiles 8 Cores upto 1000MIPS real time processing power in dual issue mode. Yes, full feature version driver can reduce the latency. If the room environment contains a large amount of EMI noise(from the behind equipment), our XU216 pcb with the full feature version driver can sound better technically due to the feedback method used.ģ) Can I use the free lite version or the full feature version windows driver with the XU208 PCB? The default inbox windows usb audio 2.0 driver has a little bit higher latency, but it only affect advanced recording usage. XU216 contains two XU208 in one silicon, the processing power of XU216 is double.Ģ) Which PCB sounds better, XU208 or XU216?įor normal usage, the sound quality is the same. XU208 is using smaller TQ64 package and XU216 is bigger TQ128 package. Please notes Windows default inbox driver does not support ASIO, it only support WASAPI to playback PCM and DSD. The full feature version windows signed driver is available in the our store.įor the latest version of MAC and Linux, no driver installation is needed for all of our xmos PCB. The firmware in our XU216 multichannel PCB is designed to require additional driver installation for use in Windows 10/11(as of 202203). No extra driver installation is needed and the XU208 PCB can support 384k PCM I2S in out for stereo playback and recording. The firmware in our XU208 and XU216 stereo PCB is compatible with the default windows inbox usb audio 2.0 driver. This item includes XMOS XU208 384kHz DXD DSD256 high-quality USB to/from I2S, to DSD/SPDIF PCB (and 2.54mm spacing 10x2row gold plated header pins, JST-XH 2pin white socket)ġ) What is the different between XU208 XMOS PCB and XU216 XMOS PCB?
