Product Description

Connect your JustBoom DAC (digital-to-analogue converter) 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 digital-to-analogue converter 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!
