With a power output of up to 60W, a single 12-24V power supply is all you need to fuel both the Raspberry Pi and the Amp4. For 4 Ohm speakers, we recommend a voltage range of 12-20V, while higher operating voltages are advised with 8 Ohm speakers. However, even with 8 Ohm speakers, a \u003ca href=\"https:\/\/thepihut.com\/products\/hifiberry-20v-4a-power-supply\"\u003e20V power supply\u003c\/a\u003e is our preferred choice.\u003cbr\u003e\u003cbr\u003eThe Amp4 not only powers the Raspberry Pi but eliminates the need for an external 5V power supply. It is designed to work seamlessly with speakers of 4-8 Ohm impedance, supporting sample rates from 44.1-192kHz (16-32bit). For enhanced capabilities, consider equipping the Amp4 with the \u003ca href=\"\/zh\/products\/hifiberry-dsp-add-on\"\u003eDSP add-on board\u003c\/a\u003e, enabling advanced digital signal processing.\u003cbr\u003e\u003cbr\u003eIn case your software doesn't recognize the Amp4 as an output option, utilize the HiFiBerry DAC+ software driver, as the Amp4 essentially functions as a DAC+ with an integrated power stage.\u003cbr\u003e\u003cbr\u003eThe Amp4's integrated voltage converter is robust enough to power even the latest Raspberry Pi 4. However, it's important to note that it isn't designed for additional power-hungry USB devices or other hardware. While low-power devices like mice and keyboards pose no issues, the system may become unstable if drawing too much additional current from USB ports or the 5V rail on the GPIOs.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"\/zh\/products\/hifiberry-amp4-pro\" title=\"HiFiBerry Amp4 Pro\"\u003eWe also stock a pro version with integrated dual-domain clocks for optimal audio clock generation.\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHigher operating voltages are only recommended with 8-ohm speakers\u003c\/li\u003e\n\u003cli\u003eWith 8-ohm speakers a \u003ca href=\"\/zh\/products\/hifiberry-20v-4a-power-supply\"\u003e20V power supply\u003c\/a\u003e is recommended\u003c\/li\u003e\n\u003cli\u003eIt is not designed to power additional power-hungry USB devices or other hardware\u003c\/li\u003e\n\u003cli\u003eIf the software you’re using doesn’t provide the Amp4 as an output option, you should use the HiFiBerry DAC+ driver as the Amp4 is a DAC+ with an integrated power stage.\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eThere is no need to add an external 5V power supply to the Raspberry Pi\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n\u003cstrong\u003e\u003c\/strong\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eStereo DAC with sample rates up to 192kHz\/24bit\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\u003eNo soldering, comes as a pre-fabricated kit, just plug it into the Raspberry Pi.\u003c\/li\u003e\n\u003cli\u003eCan be extended with the \u003ca href=\"\/zh\/products\/hifiberry-dsp-add-on\"\u003eHiFiBerry DSP add-on\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eComes with all components required to mount it.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"height: 361px;\" width=\"797\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"height: 19px;
