Fully powered by the USB port on your laptop or computer rig, the Proton is a self contained USB DAC and headphone amp. The Proton is compact, so you can throw it in your travel bag and use it as a portable headphone amp. Besides supporting 24 bit data (@ 44.1, 48, 88.2 and 96k sampling), a Lithium-Ion battery provides clean power to the DAC module and headphone output circuit.
Operation could not be simpler – plug the supplied USB cable from your computer into the Proton, plug in your headphones or run the analog outputs to your preamp, and you are ready to listen. In stock, now, at Pitch Perfect.
