AUDIOPHONICS Digipi+ PRO Digital interface WM8804 for Raspberry Pi

Here is a new and more elaborate version of the PI3 SPDIF Audiophonics DIGI+ PRO interface. Still featuring the WM8804 low jitter digital management chip and a Pulse PE-65612 audio isolation transformer, this interface allows Toslink coaxial and optical digital output to drive a DAC. A location on the printed circuit board allows an optional 75 Ohm BNC output to be soldered for the most demanding amateurs.

This version now includes two high-precision clocks for 16bit 44.1khz frequency multiples (CD format resolution) and 48khz multiple for 24bit 192khz high definition file resolutions. This technological contribution allows a better decoding accuracy at the exact frequency of the file sent to the DAC.

This version is delivered with an IR (infrared) cell and a connector dedicated to the GPIO of PI 3 and PI 2. Once connected to the GPIO connector, simply choose the right I2S HIFIBerry driver in its Raspberry Pi Audio distribution:

• Moode AUDIO : driver HIFIBerry Digi et Digi+
• Picore Player : driver HIFIBerry Digi et Digi+

To mount this DAC on a Raspberry PI 3 you will need the following spacers:

• Brass spacers M2.5X5mm
• Nut HU Stainless steel M2.5x2mm
• Brass spacers M2.5X20mm

Characteristics:

• 192khz SPDIF 24bit PCM interface
• Screws not delivered
• Output: Coaxial Spdif and Toslink optics
• Supported sampling rates: 24bit 192 khz
• This interface has two clocks 22,579 mhz and 24,576 mhz.
• IR receiver, XBMC control with RC6 remote control (not included)
• PCB dimensions: 86 x 56x 56x 22mm
• Weight: 26g
• I2S driver : HIFIberry DIGI +pro

This interface is compatible with Volumio using the Hifiberry Digi+Pro driver.
