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.\u003c\/p\u003e\n\u003cp\u003eWith 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.\u003c\/p\u003e\n\u003cp\u003eThe board powers the Raspberry Pi, there is no need to add an external 5V power supply to the Raspberry Pi.\u003c\/p\u003e\n\u003cp\u003eThe Amp4 Pro is designed to work with all speakers or 4-8 Ohm impedance. It supports sample rates from 44.1-192kHz (16-32bit). It can be equipped with the DSP add-on board to enable advanced digital signal processing capabilities.\u003c\/p\u003e\n\u003cp\u003eThe Amp4 Pro integrated voltage converter is powerful enough to power even the new Raspberry Pi 5. Due to the improved voltage regulator, it’s possible to power the official 7″ Raspberry Pi touchscreen display or other additional 5V devices.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote - L\/R outputs can’t be bridged!\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible with all 40-pin models of Raspberry Pi, including Raspberry Pi 5\u003c\/li\u003e\n\u003cli\u003eStereo DAC with sample rates up to 192kHz\/24bit\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDual domain clock circuit for optimal audio clock generation\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eUp to 2x30W output power output\u003c\/li\u003e\n\u003cli\u003eUses a single external power supply 12-24V (see below) to power the amplifier and the Raspberry Pi\u003c\/li\u003e\n\u003cli\u003e5V power supply up to 5A\u003c\/li\u003e\n\u003cli\u003eNo soldering, comes as a pre-fabricated kit, just plug it onto the Raspberry Pi.\u003c\/li\u003e\n\u003cli\u003eCan be extended with the HiFiBerry DSP add-on\u003c\/li\u003e\n\u003cli\u003eComes with all components required to mount it.\u003c\/li\u003e\n\u003cli\u003eEAN: \u003cspan\u003e4260439551085\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable width=\"656\" style=\"height: 576px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 18px;\"\u003e\n\u003ctd style=\"height: 18px;
