Default New XMOS Multichannel PCB

Dear friends,
A new xmos multichannel PCB is just released.
  • 4 layer PCB, Ultra low phase noise ndk audio oscillator
  • Upto 32 channels or 384kHz with different firmware
  • XMOS Xcore-200 XU216 with 2 Tiles 16 Cores upto 2000MIPS in dual issue mode.

Click the image to open in full size.

The default firmware on the DXIO32ch support 8 channels 192kHz I2S input , 8 channel 192kHz I2S output, spdif output, OLED VU meter and volume up/down control button

Extreme diyer can use the onboard full size XSYS connector to program the xmos with their customized firmware to add more feature and function. (For programming support, please refer to the xmos official website and xcore.com for question about xmos programming, the PCB portmap is shown in the item image.)

The usb audio source code can be downloaded from xmos.com and the VU meter patch can be downloaded from xcore.com released under bsd license.

To compare, the xmos used in the stereo 384k USB I2S PCB is 500MIPS processing power. Our test shows that the OLED VU meter patch can degrade the audio quality if it is not used with the new 2000MIPS XMOS.

Default New XMOS Multichannel PCB

This is very exciting news! The DIY community has been waiting for a good quality multichannel USB interface for a very long time.

Will it be possible for Native DSD 256 8 channel support with Linux?

Can you develop the firmware for Native DSD 256 support on Linux?

We think DSD support is very important.

The very best platform to use for testing is HQ player.

If you download Audiolinux:

http://www.tophifi.it

It's perfect. It has HQplayer pre-installed. Just copy to USB stick and boot from stick. Very easy way to to test HQplayer/Linux. And very best sound as well.

Thank you. We look forward to the development!

It would be great if your converters wouldn't be visible in a system as a DIYINHK... but as a native XMOS devices

If you plug in one of these converters to your PC... the device name will be something like:

DIYINHK DXIO USB2.0...

Yes that's because it's their interface. If your an OEM customer, and order large quantities, they can change that to whatever you want. Even print your name on the PCB.

Hi diyinhk,

XMOS DSD DXD 384kHz high-quality USB must be fed with +5V by USB input?

It seems like an interesting solution for an USB ADC. Do you have more informations on interfacing I2S inputs with the board ?
