HiFiBerry DAC2 ADC Pro Audio HAT for Raspberry Pi

The HiFiBerry DAC2 ADC Pro is a high-resolution digital-to-analogue and analogue-to-digital converter sound card, specifically engineered for Raspberry Pi models equipped with a 40-pin GPIO header. It has been meticulously optimised for a singular purpose: delivering the absolute best in audio playback and recording quality on the Raspberry Pi platform.

Unlike standard audio boards, the DAC2 ADC Pro is designed for applications demanding both pristine playback and professional-grade recording capabilities. It features dedicated stereo input and output connections, ensuring clear two-way audio communication for your projects.

At the heart of its performance are high-quality Burr-Brown DAC and ADC components, capable of handling audio at up to 192kHz/24-bit resolution. This guarantees exceptional sound fidelity whether you are listening to music or capturing audio from external sources.

For precise control, the board includes independent hardware volume control for both the DAC (output) and ADC (input) sections. Power is supplied via ultra-low-noise linear voltage regulators, which are critical for minimising electrical interference and achieving optimal audio performance.

A built-in microphone bias voltage simplifies the connection of electret microphones, making it an ideal solution for voice recording, podcasting, or telephony applications. The board also offers support for the optional HiFiBerry DSP add-on, allowing for advanced audio processing and equalisation.

Designed for ultimate convenience and signal integrity, the DAC2 ADC Pro connects directly to the Raspberry Pi's GPIO pins, requiring no additional cables or connectors. This HAT (Hardware Attached on Top) form factor ensures a secure and compact installation. It is compatible with all Raspberry Pi models that feature a 40-pin GPIO connector, including the Raspberry Pi 3, 4, and 5.
