UNIKA PRO-USB
UNiKA PRO-USB is a professional passive DI box designed to convert digital USB audio signals such as those from mobile phones, tablets, laptops, computers and other digital audio sources into low impedance balanced analog signals as required by a mixer, sound card, preamplifier or powered speaker. Since PRO-USB is powered via the USB TYP C connector, no batteries or other power supplies are required.
The customized audio-isolation transformer of UNiKA PRO and the integrated 192 kHz/32-bit digital audio converter (DAC) provide unaltered audio quality and is compatible with digital DSD formats and all popular lossless and compressed music formats. PRO USB has a built-in mini-TRS headphone output and a volume control that can drive 16Ω~600Ω headphones.

XLRs connect the transformer-balanced low impedance outputs to the inputs of a mixing console, sound card, preamplifier, active speaker, or other audio device via a standard XLR cable. GND/LIFT - Interrupts the ground at the output of both transformers to eliminate hum and noise due to ground loops.
