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!

Technical Information:

Burr-Brown / Texas Instruments PCM5102A DAC chip – 384kHz / 32 bit. Please note that due to restrictions of the S/PDIF receiver the max quality is limited to 108kHz / 24 bit
Texas Instruments TPA6133A2 headphone amplifier – 138mW
112db SNR and -93db THD for best-in-class audio
Advanced ESD protection on both headphone and RCA outputs
Ultra low noise voltage regulator for the best audio output (LDO 10uVrms)
5v microUSB power input requires at least 100mA when using RCA connectors or at least 200mA when using headphone connector. We recommend at least a 500mA power supply
Stacking with JustBoom Amp by way of board-to-board connector. All of the required mounting hardware in order to do this is included with the two products for ease
