ARX USB-DI VC digital-to-analog direct box.Melbourne, Australia (August 25, 2008)–Arx has added the USB-DI VC digital-to-analog direct box to its AudiBox range. It is a plug-and-play digital-to-analog pro audio interface, essentially removing the need to use any existing soundcard outputs, but now the output level can be modified external to the computer.
The product features full transformer balanced output isolation to eliminate earth loops/ground hum and other extraneous interaction noise and distortion.
The addition of the volume control allows the USB DI-VC to be used without a mixer. This option can be used when driving active loudspeakers from a laptop, since the level control lets one reduce the level instantly to suit the required SPL.
