HiFiBerry DAC2 Pro
The HiFiBerry DAC2 Pro is a high-resolution digital-to-analogue and analogue-to-digital converter for the Raspberry Pi (newer models with a 40-pin GPIO connector).
This is a special sound card for the Raspberry Pi, optimised for one specific use case: affordable high-quality audio playback.
Note: This board will not fit inside the HighPi case range due to the headphone connector.
DAC2 Pro or DAC2 HD? If you’re just looking for the best audio quality – the answer is easy: the DAC2 HD. It offers lower distortions, higher signal-to-noise-range and higher dynamic range than the DAC2 Pro.
If you’re on a budget, but still want a high-quality DAC, this DAC2 Pro might be your choice – the DAC2 Pro is a new and improved version of the popular DAC+ Pro, adding a headphone connection as well as the ability to attach a DSP add-on board (coming soon!)
DSP Add-on for the DAC2HD now available!
