HiFiBerry DAC+ ADC
The HiFiBerry DAC+ ADC is a high-resolution digital-to-analog converter for the Raspberry Pi (newer
models with 40 pin GPIO connector). It is specifically designed for applications that need not only
playback, but also recording functionalities.
Features
• Stereo input and output
• Dedicated 192kHz/24bit high-quality Burr-Brown DAC
• Hardware volume control for DAC. You can control the output volume using “alsamixer” or any
application that supports ALSA mixer controls.
• Balanced input supported with optional XLR connectors
• 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, it 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
• 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
Use Recommendations
• Music playback on the Raspberry Pi
• Connect devices such as mobile phones, MP3 players, Amazon Alexa, or other gear.
• Music processing (connect synthesizer and process audio on the Pi)
• Karaoke devices

Input Gain Settings
The jumper block is used to configure the input
stage. In most cases it is recommended to the
the default setting without additional input
gain. 32dB gain can be used to connect dynamic
microphones. Jumpers are numbered from top
to the bottom.
