The HiFiBerry DAC2 HD is a high-end digital-to-analogue converter for the Raspberry Pi (newer models with 40 pin GPIO 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, the DAC2 Pro might be your choice.
Custom current-to-voltage output stage with high-end filtering
Four ultra-low-noise linear voltage regulators for optimal audio performance
Low-jitter clock for optimised clock performance (independent from Raspberry Pi clock sources)
Hardware volume control for DAC. You can control the output volume using “alsamixer” or any application that supports ALSA mixer controls.
Supports HiFiBerry DSP add-on module
Connects directly to the Raspberry Pi, no additional cables needed
No soldering - comes as a pre-fabricated kit. You just plug it onto the Raspberry Pi, it conforms to the Raspberry Pi hardware-attached-on-top (HAT) specification.
Compatible with all Raspberry Pi models with a 40-pin GPIO connector
Directly powered from the Raspberry Pi, no additional power supply required
HAT compliant, EEPROM for automatic configuration
Gold plated RCA output connectors
Comes with all components required to mount it. We include 4 M2.5x12mm spacers to fix the board onto the Raspberry Pi
Requires latest Linux kernel.
