DAC+ – Improve your sound (Pro專業版)

HiFiBerry DAC+ Pro

The HiFiBerry DAC+ is a high-resolution digital-to-analog converter for the Raspberry Pi Model A+/B+ and 2B. This is a special sound card for the Raspberry Pi, that is optimized for one specific use case: the best audio playback quality.

Dedicated 192kHz/24bit 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
No soldering Comes as a pre-fabricated kit. You just plug it onto the Raspberry Pi B+. Mounted in less than a minute.
Compatible with Raspberry Pi model A+/B+ and 2
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 jitter 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 real hardware hackers have no problems with this.

Notice about the compatibility with Raspberry Pi Model A and B: This board is only compatible with the new Raspberry Pi Models A+/B+ and 2. If you have an older Raspberry Pi, please use our HiFiBerry DAC.
