The DI-USB is a high-resolution stereo digital audio converter (DAC) and direct box that is designed to connect to any computer system to seamlessly transfer digital audio to analog.
A professional Hi-Z direct input is also equipped, this is most commonly used with guitar pickups or keyboards, it also can be fed either from a linelevel output from the head (pad set to -20dB) or from the amplifier power output. A stereo pair of balanced XLR audio outputs with adjustable level control then feeds the signal to a microphone preamplifier, PA system, mixing console or even a powered speaker!
Made for plug and play simplicity, the DI-USB will automatically be listed as an available sound card in the audio settings in all popular operating systems,including Windows 7/8, Windows 10 and Mac OSX.Connection to a computer is accomplished through a standard USB type-B port. Digital-to-analog conversion can be monitored on headphones through the 3.5mm analog output jack to check signal quality and level before connecting to a sound system. Two isolated output transformers are equipped to eliminate any hum or buzz caused by ground loops. To further reduce susceptibility to noise, this is augmented with a ground lift switch that lifts pin-1 on both XLR jacks.
OVERVIEW
The Unika DI-USB is a high-resolution stereo direct box designed to convert sound files from a laptop computer, it is a fully USB 2.0 compliant, 24bit digital to analog audio converter and also a direct input that lets you interface a high impedance (Hi-Z) audio output with professional low impedance (Low-Z) PA and recording systems.
In the case of the DI-USB Box, the digital audio signal is converted to analog and feeds directly into the direct box circuit to produce Low-Z balanced left and right stereo signals.

The built in preamp allows you to adjust the output level from mic-level to line-level and enables the DI-USB Box to connect directly to mixing consoles, power amplifiers and self-powered speakers alike. The DI-USB Box ensures the digital signal is delivered to the PA as faithfully as possible.
