JustBoom Amp

The JustBoom Amp comes with an amplified stereo output and an 2x55W peak output. It impresses with its diverse fields of application. What makes it special is the possibility to use the Amp as an single amplifier, but it can also be stuck on top of the DAC or DAC HAT. The needed screws and spacers are included within the delivery scope.

The Amp requires a 2.1mm power supply with 8-24V for optimal usage. If the Amp is used together with the DAC Hat, one power supply can power alll three components: the Amp, the DAC HAT and the Raspberry Pi as well. We recommend using this power supply.
