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! Features

* Stereo output

* Integrated headphone amplifier

* Can be equipped with an additional Digital Signal Processor (DSP) for flexible audio processing

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

* Hardware volume control for DAC. You can control the input and output parameters 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 required

* No soldering - comes as a pre-fabricated kit

* Conforms to hardware-attached-on-top (HAT) specification with EEPROM for automatic configuration

* Compatible with all Raspberry Pi models with a 40-pin GPIO connector

* Directly powered from the Raspberry Pi, no additional power supply

* Two ultra-low-noise linear voltage regulators for optimal audio performance

* Low-jitter dual-domain clock for optimised clock decoupling from the Raspberry Pi

* 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

* Audio connector to connect the analogue audio amplifier
