DI-USB
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.
