HiFiBerry DAC2 ADC Pro

The HiFiBerry DAC2 ADC Pro is a high-resolution digital-to-analog and analog-to-digital converter for the Raspberry Pi, which combines our well-known DAC2 Pro with an analogue input. Both input and output support sample rates up to 192kHz. It is our first DAC/ADC board that also supports our DSP add-on. This is a special sound card for the Raspberry Pi, optimised for one specific use case: the best audio playback and recording quality! It is specifically designed for applications that do not only need playback, but also recording functionalities. Features

* Stereo input and output

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

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

* Hardware volume control for DAC and ADC. You can control the input and output parameters using “alsamixer” or any application that supports ALSA mixer controls.

* Support for the HiFiBerry DSP add-on

* Connects directly to the Raspberry Pi, no additional cables needed

* No soldering, comes as a pre-fabricated kit

* 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

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

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

* Mic bias voltage for the use with electret microphones

* No anti-aliasing filter in the input path for best recording bandwidth

* 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
