![]() If you’ve got a tiny socket set, that might be the way to go to save yourself some aggravation. The little plastic hex nuts don’t have a lot of room near the pins on top so I had to turn them very slowly with my SOG multitool. I left the extra bits coming out of the top, because mounted the other way made the stack too tall to fit properly into the case. I did have to figure out which way the standoffs go. No need for the usual Raspberry Pi USB power supply with this and you shouldn’t use one with this setup. That black rectangular chunk near the bottom of the device contains left and right speaker terminals, another terminal for installing a hard-wired, 14V power supply, and a circular pin and ring plug for the included 14V power adapter which drives the whole thing. I’ll report back with a schematic when I have it working. I plan on using mine to install a rotary encoder and a pushbutton for volume knob and play/pause. The GPIO pins remain available for additional hardware hacking if needed. It also provides power back to the main board through the GPIO pins. By using the I2C connection on the Pi, it provides a direct hardware connection to the processor, bypassing the USB bus and effectively becoming isolated from any noise or interference from the Pi’s main board. And therein lies the beauty of this little thing. The Amp 2 sits on top of the GPIO pins on the Raspberry Pi as a dedicated HAT. It’s not going to win any beauty contests, but once it’s together, I plan on hiding it in a cupboard in the kitchen.Īssembly was trivial. The case it came with is a simple ABS plastic thing with a snap cover, some plastic standoffs and little silicone feet. The simple cardboard box the Amp2 came in has a nice little message on it and not much else. I’ve included my Raspberry Pi 3 and an apple for comparison in the above image. ![]() The included power supply is easily the biggest piece in the kit. “This product is made with love while listening to good music.”Īll told, it’s a surprisingly small package. I ordered it last week and it arrived intact all the way from Switzerland. Properly fed, I proceeded to unbox my newly arrived AMP 2 kit. Tuna and pickled onions on Co-Pain Sourdough. I had a (TRIGGER WARNING!) tuna sandwich with pickled onions on sourdough bread from an excellent new bakery here in town. The onboard DAC is also upgraded to support 44.1KHz-192KHz audio files.įor any project of sufficient complexity, you should really start with a full stomach. Update: Originally, the Amp+ was a 25WPC amp, the new Amp2 pictured above is capable of 30WPC, 60 Watts total power. Tiny but powerful, 30WPC Class D amplifier and integrated DAC on a board half the size of a credit card. ![]() All they need is an amplifier and a sound source, and this little module looked like it might fit the bill. I have been unable to effectively play from my extensive, NAS-based local library on the Sonos for some time, despite my best efforts to make it work. Continuous, nagging app updates with no visible improvements, degradation of performance and playback limitations have forced me to look for alternatives. Their recent push to provide Amazon Alexa integration, a new user account system and changes to their privacy policy that allows feedback to Sonos Inc with my personal music preferences, room names and who-knows-what-else left me a little queasy. The past year or so, I’ve become increasingly frustrated by the Sonos platform. Their closed ecosystem was another sour note for me, but I pushed past that in favor of convenience. Initially, they were something of a marvel of integration and software polish, providing ease of setup and room filling sound for … they are not cheap. I’ve been a Sonos user for probably five years now.
