It delivers up to 60W of power, supports Bluetooth connectivity, and is compatible with various speaker impedances, making it an ideal choice for audiophiles and tech enthusiasts alike. ## Description 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. You only need a single 12-24V power supply to power the Raspberry Pi and the Amp2. With 4 Ohm speakers, we recommend 12-18V. Higher operating voltages are only recommended with 8 Ohm speakers. However, even with 8 Ohm speakers an 18V power supply is the best choice in our opinion. It powers the Raspberry Pi, there is no need to add an external 5V power supply to the Raspberry Pi. The Amp2 is designed to work with all speakers or 4-8 Ohm impedance. It supports sample rates from 44.1-192kHz (16-32bit). The speaker connections are the similar as on the Amp+. Note that the polarity of one channel is reversed compared to the Amp+. Check the prints on the PCB for the correct polarity! If the software you’re using doesn’t provide the Amp2 as an output option, you should use the HiFiBerry DAC+ driver as the Amp2 is basically a DAC+ with an integrated power stage. The Amp2 integrated voltage converter is powerful enough to power even the new Raspberry Pi 4. Just note that it is not designed to power additional power-hungry USB devices or other hardware. There isn’t a problem with low-power devices like mice, keyboards and similar. There might be even enough power for external hard disks, but the system might become unstable if too much additional current is drawn from the USB boards or the 5V rail on the GPIOs. ## Features - Mount it onto the Raspberry Pi and you have a stereo audio system. - You only have to connect your loudspeakers.

I wasn't expecting much from it at first. It was after all just 45 dollars and small enough to fit snugly on top of a pi 3b. Just expected it to be a cute toy to tinker with for awhile and then pass it on to someone else or store it in a drawer. I was very wrong.This little amp sounds great! I would not consider myself an audiophile by any means but I think I know what sounds better than what most people are used to now a days, and this thing is by far, one of them.I installed it on a raspberry 3b+ running with volumio. Setup was quick and simple if you have a bit of tinkering experience. At first I hooked it up to a pair of micca covo s. These are tiny cube speaker with relatively low efficiency (85 db) , but it made them sound quite good. I had them in my room for night listening on my bed and they were plenty good for me. Things however went from good to great when I found some vintage (1976) Akai sw-157II in a storage room in my parents house. These were my dads speakers after graduating college. One seemed in good condition but the other had a hole in its woofer probably from mice. I took them home out of curiosity and hooked them to the amp2. I was left wide mouthed. This little amp2 was absolutely rocking these big speakers. They were loud, almost painfully loud at 90% volume in my room. The highs were crisp and clear but not harsh at all, the bass was tight and punchy, I could feel it in my chest. I was incredibly excited. The sound was clear and defined, somewhat warm, very pleasant and non fatiguing, something I wasn't expecting at all.I was planning on returning these big outdated speaker to my parents after cleaning them and testing that they worked, but its been more than half a year now and I dont think they are leaving my bedroom any time soon. I use this setup almost daily, it has plenty of power to spare. On one of his visits, the old man was very impressed by how his old speakers were sounding. He couldn't believe that much sound was coming from this little amp.The picture shows the akais by the little micca cubes and the amp2 in the center.Definitely recommended. ### ⭐⭐⭐⭐⭐ Amazing Product *by T***R on August 22, 2021* I can’t suggest this product enough. I’ve tried those cheapo amps that you can buy from China and even they pad problems with my 4Ohm speakers. This thing outputs loud and clear sound. I had the dial the volume back in my pi after installing this because the other amps just couldn’t do it.Make sure you know the ratings on the speakers that you will be using, because you may been a more stronger power supply. Make sure you read the details of this item so that you buy the correct power brick. The 18v worked great for me, and I didn’t need to give the pi any additional power through usb. ### ⭐⭐⭐⭐⭐ Works fine with Pi Zero W. *by B***N on June 10, 2021* I stream music to a Pi Zero W over WiFi via a Logitech Media Server.The manufacturer recommends using a Pi 3 or Pi 4 but I find it works fine with a Pi Zero W; though I run it without video and only stream music, no videos, through it so that is less demanding.I replaced a DAC that was would sometimes crackle and pop between songs. This HifiBerry is completely noisefree. The builtin amp has plenty of power for a pair of small bookshelf speakers.I use Squeezelite and it can sync with a Logitech Squeezebox, so when I change music on the Squeezebox it also changes on the Pi, an unexpected bonus. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/47731414-amp2](https://www.desertcart.pt/products/47731414-amp2) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-24*
