HiFiBerry DAC2 HD

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. DSP Add-on for the DAC2HD now available! 60W Class-D Amplifier add-on now available!

Features

* Stereo output

* Dedicated 192kHz/24bit high-quality Burr-Brown DAC

* 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 at least Linux kernel 4.19.97
