This is a special sound card for the Raspberry Pi, that is optimized for one specific use case: the best audio playback quality.
This is the Standard RCA version whic uses RCA connectors that you know from your normal stereo equipment. The HiFiBerry, like all Pi HATs, sits right on top of your Pi's GPIO pins with no additional cables needed and integrated EEPROM for automatic configuration.
Dedicated 192kHz/24bi high-quality Burr-Brown DAC for best sound quality (ESS instead of Burr-Brown on DAC+ Light)
Hardware volume control. You can control the output volume using alsamixer or any application that supports ALSA mixer controls (not available on DAC+ Light)
Connects directly to the Raspberry Pi no additional cables needed
Directly powered from the Raspberry Pi no additional power supply
Ultra-low-noise voltage regulator for optimal audio performance
Available with different output connectors: RCA or 3.5mm phone jack (DAC+ Light and Pro only available with RCA jacks)
Integrated EEPROM for automatic configuration (not DAC+ Light) The board is conform to the Raspberry Pi hardware-attached-on-top (HAT) specification. Note that this feature is still in development by the Raspberry Pi foundation. You will be able to upgrade your HiFiBerry DAC+ when it is officially available. The sound card already works without this feature.
Comes with all components required to mount it. We include 4 M2.5x12mm spacers to fix the board onto the Raspberry Pi.
DAC+ Pro advanced features:
Gold-plated connectors: Gold-plated RCA connectors ensure optimal connection to your RCA cables.
Dual-domain clock circuit The DAC+ Pro uses its own on-board ultra-low-jitter clock generator. To have the lowest jitte values, there are 2 different clocks on board: one for 44.1/88.2/176.4 kHz sample rates and another for 48/97/192kHz.
Hackable: The board can be modified to allow external power supply for the analog part of the board. Also you can connect external I2S DACs. These features need soldering on the board. This will void warranty, but rea hardware hackers have no problems with this.
This board is ONLY compatible with the Raspberry Pi 2 Model B, Pi 3 Model B, and the P Models A+ and B+! While we haven't tested it with the Pi Zero, it likely works with it!
This case fits the Raspberry Pi B+, Raspberry Pi 2 and Raspberry Pi 3 with the HiFiBerry DAC+ (RCA versions), Digi+ or Amp+. It is very simply to mount without additional tools. Just plug plug the HiFiBerry card onto your Raspberry Pi and snap it into the case.
