The HiFiBerry Amp4 Pro is an advanced version of the standard Amp4 DAC/amplifier for Raspberry Pi, with integrated dual-domain clocks for optimal audio clock generation.
Mount it onto the Raspberry Pi and you have a stereo audio system – you only have to connect your loudspeakers. It provides up to 60W power and you only need a single 12-24V power supply to power the Raspberry Pi and the Amp4 Pro Board.
With 4-Ohm speakers, we recommend 12-20V. Higher operating voltages are only recommended with 8-ohm speakers. However, even with 8 Ohm speakers a 20V power supply is the best choice in our opinion.
The board powers the Raspberry Pi, there is no need to add an external 5V power supply to the Raspberry Pi.
The Amp4 Pro is designed to work with all speakers or 4-8 Ohm impedance. It supports sample rates from 44.1-192kHz (16-32bit). Itcan be equipped with the DSP add-on board to enable advanced digital signal processing capabilities.
The Amp4 Pro integrated voltage converter is powerful enough to power even the new Raspberry Pi 5. Due to the improved voltage regulator, its possible to power the official 7 Raspberry Pi touchscreen display or other additional 5V devices.
