The X10-I2S module allows it user to enjoy a USB interface to I2S, Coaxial and Optical in a very simple way. It is very useful when it comes to upgrade any DIY audio system based for example on a Raspberry Pi to provide new possibilities.

List of modules of the X10 and X20 series sold separately:

• X10-DAC : Module DAC I2S RCA PCM1794A 24bit 192kHz
• X20-DAC : Module DAC I2S RCA ES9028Q2M 24bit 192kHz
• X10-PWR : Power supply linear regulated
• X20-XLR : Module DAC I2S XLR ES9028Q2M 24bit 192kHz

A fully autonomous interface

The SA9227 interface is first designed to be used directly with a SBC Raspberry Pi.

It can also operate in standalone mode, a solution that allows changing the DAC Module quickly and effortlessly for benchmarking hardware or to favor a specific speaker / amp technology when listenning.
This solution is therefore as good as practical and economical.

Components

The interface also incorporates an ultra-low phase jitter SiTime SiT8208 SiTime oscillator, a Pulse PE-6561NL digital signal transformer with a design to limit EMI noise and interference, and an ultra-low noise voltage regulator from Texas Instruments for optimal operation.

Use X10-I2S interface with Volumio

The X10-I2S interface is compatible with Volumio. To be able to use these two solutions together, a simple manipulation is necessary.

• In the Volumio interface, go to the Playback Options menu.
• Disable I2S DAC option.
• In the Output Device field, select xCORE-AUDIO Hi-Res 2.
• Reboot Volumio.
