JustBoom DAC SKU: JBM-007
The JustBoom DAC is a standalone high-resolution digital-to-analog converter offering 108kHz/24bit
lossless audio playback for your projects. We’ve designed the JustBoom DAC 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
Connect your JustBoom DAC to a set of powered speakers, headphones or an audio amplifier and
you can be up and running quickly, enjoying flawless, crystal-clear high quality audio playback within
minutes of unboxing. If you need amplification or additional outputs for passive speakers, the
JustBoom DAC is also compatible with the JustBoom Amp – just stack the Amp on top with the
mounting hardware and board to board connector and you will be good to go.
This affordable, standalone DAC has among the best value for money available on the market and
truly reduces the barriers to entry for versatile high quality audio playback. The digital (S/PDIF) inputs
include both optical (TOSLINK) and coaxial/RCA connector options. The onboard DAC chip offers a
384kHz/32 bit output (although this is limited due to the input S/PDIF receiver to 108kHz/24bit). The
JustBoom DAC additionally includes a 138mW headphone amplifier.
The board outputs line level audio over RCA and also offers a headphone amplified output over
3.5mm jack cable. The board is powered by a standard 5 volt microUSB power supply – this is a
common power supply in tablets and smartphones so many of you will already have one available or
can pick one up for a good price!
