HiFiBerry DAC2 Pro XLR

This is a special version of the HiFiBerry DAC2 Pro with a pair of XLR jacks! The output is fully balanced and the board can be equipped with the additional HiFiBerry DSP add-on module. This is a special sound card for the Raspberry Pi, optimised for one specific use case: affordable high-quality audio playback! It is strongly recommended to mount this board into a solid metal case, otherwise, mechanical stress while plugging/unplugging XLR connectors might damage the XLR connectors. We offer a matching steel case here. The DAC2 Pro XLR comes with integrated dual-domain ultra-low-jitter clocks and gold-plated XLR connectors. It can be simply plugged onto your Raspberry Pi, without any soldering. 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

* 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

* XLR Connectors

* Comes with all components required to mount it. We include 4 M2.5x12mm spacers to fix the board onto the Raspberry Pi
