TPA3116 / RuneAudio Project

The new TPA3116 2x50w digital amp just arrived, and it's going to be part of a new project.

Here it is, in all its glory, with :


To bring it all together, I'm planning to use this enclosure:


The plan is to stuff the amp, power supply, a Raspberry Pi B+ with HifiBerry, a phono preamp and a passive source selector inside the case. There's still a few bits and pieces awaiting arrival from China, so this may take some time. Still, it's a start.

Lol I didn't know the "banana for scale" meme
Cool project, have you also considered to add some cool features like a LCD display or a rotary encoder volume control ( is developing it for its DAC)?

A few bits and pieces arrived, I will have to keep my RuneAudio RPi player in its separate enclosure due to space constraints.

So the amp will have the TPA3116 amplifier board, an active phono preamp. And then a passive pre with selector switch, volume and balance. And a power supply of course.

Here's the front panel, partially drilled to get the power button in. The 9V battery is just to demonstrate the LED in the power button:
