ARX Systems has announced the release of an updated version of its USB DI-Q USB-Analog interface — designed to facilitate secure playback and monitoring of audio files — offering a new front panel annotation to make it suitable for use in a wider range of applications, including corporate and education.
The USB DI-Q allows users to monitor and cue audio files in a closed headphone environment and switch/enable the audio output to a public address/sound system as required. The simplicity of the product setup is intended to foster easy integration into the existing AV infrastructure of a building.
It also provides a transformer-balanced output for the isolation required to eliminate earth loops/ground hum and other extraneous noise and distortion. Once in place, it offers touch button operation and the simplified user interface is intended to make it easier to use for non-technical operators.
The USB DI-Q can interface any USB-equipped computer (especially notebook computers) with the balanced inputs of professional sound systems. It installs as a compatible “plug and play” generic USB audio device, requiring no special driver program installation on Mac OSX, Windows XP, 7/8/10. Also included is a high-quality USB-A to USB-B cable.
The front panel offers an overall playback volume control for both headphone and XLR outputs and an “enable audio to room” switch and indicator LED. The rear panel has a type B USB input socket and status LED, summed (mono) output XLR with groundlift switch, and a 6.5 mm/1/4 in headphone output socket.
