HiFiBerry Digi2 Pro v2.2

HiFiBerry Digi2 Pro is a high-quality S/PDIF output for the Raspberry Pi. It uses the I2S sound port that connects directly to the CPU without the need for an additional USB conversion.

It also supports our DSP add-on board now that allows to process your audio before sending it to the output. The board can be equipped with an additional BNC connector. Note that you have to solder this by yourself.

Fully compatible with the latest Pi4 hardware (and all other Raspberry Pi’s with the 40-pin header)

Specifications

• Output impedance: 75 Ohm
• Channel count: 2 (support for non-audio data e.g. Dolby Digital, DTS)
• Power consumption: <0.3W
• Sample rates: 44.1-192kHz (see below for TOSLink)
• SPDIF output 2-channel
• Can be equipped with an additional Digital Signal Processor (DSP) for flexible audio processing
• No volume or sound controls - passes digital audio as it is sent from the application (“bit-perfect”)
• Output isolation transformer
• Connects directly to the Raspberry Pi, no additional cables required
• No soldering - comes as a pre-fabricated kit
• Compatible with all Raspberry Pi models with a 40-pin GPIO connector
• Directly powered from the Raspberry Pi, no additional power supply
• Low-noise linear voltage regulator
• Low-jitter dual-domain clock for optimised clock decoupling from the Raspberry Pi
• HAT compliant, EEPROM for automatic configuration
• Comes with all components required to mount it. HiFiBerry include 4 M2.5x12mm spacers to fix the board onto the Raspberry Pi

Note

Not all DACs support sample rates (96kHz, 192kHz) via TOSLink. Check the documentation of your DAC
