HiFiBerry DAC2 Pro

The HiFiBerry DAC2 Pro is a next generation digital-to-analog converter for the Raspberry Pi. Hifi enthusiasts can expect crystal clear sound, thanks to the new, further perfected design. A special feature is the integrated headphone amplifier. In addition, an optionally available DSP card can also be plugged in, e.g. to operate an equalizer for speaker or room correction.

Included are 4 M2.5x12mm spacers for mounting on the Raspberry Pi.

Note: The DAC2 Pro is compatible with Max2Play with Buster-Image (V2.53 or newer).
