JustBoomAmp
SKU: JBM-008
The JustBoom Amp is a standalone high quality audio power amplifier that is designed to either
stack on top of the JustBoom DAC / DAC HAT or alternatively take a line level input. We’ve designed
the JustBoom Amp to be simple to use – with no soldering required and all the mounting hardware
already provided, this is a true plug and play device
Description
The JustBoom Amp provides a 2x55W (peak) amplified stereo output. Just connect your JustBoom
Amp to a set of passive speakers and you can be up and running quickly, enjoying flawless high
quality audio playback within minutes of unboxing. Includes an advanced Class-D power amplifier
chip for a peak power output of 2 x 55 Watts. The JustBoom Amp outputs audio over two speaker
cable connector blocks that accept anything up to 14 AWG cable and will provide crystal clear audio
to either 4 or 8 Ohm passive speakers.
JustBoom Amp can either be used as a standalone amplifier, or it can be stacked on the JustBoom
DAC HAT or DAC boards to make a fully integrated DAC/Amp combo by means of a board to board
connector and mounting hardware. Give your audio an extra kick, and extra output options for a
more versatile and affordable high-quality audio experience!
The JustBoom Amp is designed with a 2.1mm DC jack power input which can accept an 8 to 24 Volt
power supply. When stacked on the JustBoom DAC it can backpower the DAC board, and when
stacked on the JustBoom DAC HAT it can backpower both the DAC HAT and the Raspberry Pi too
(at the 2.5A for full Pi3 compatibility) meaning you only need a single power supply for the entire
system…saving you time and money.

Texas Instruments TPA3118D2DAP Class-D amplifier chip with maximum power output of 2 x 55 W (
2 x 30 W RMS)
On the JustBoom Amp there are five line input connections. For balanced inputs: L+ is hot line L-
cold line for left channel; R+ hot line, R- cold line for right channel; middle is ground (or cable shield)
connection. For unbalanced L+ is left line, R+ right line, L-, R- and gnd are ground connections and
all three inputs should be shorted to same input ground.
Dual inductors on board for footprint efficiency
