ARX Systems has released an updated version of its USB DI-Q USB analogue interface.

ARX Systems USB DI-QOriginally designed by ARX in response to a specific request from the Australian Court System, the USB DI-Q provides a straightforward interfacing solution for secure playback and monitoring of audio files. The updated front panel annotation on the new version of the USB DI-Q make this interface suitable for use in a wider range of applications, including corporate and education.

The USB DI-Q allows the user 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 setting the USB DI-Q means that it can be integrated easily into the existing A/V infrastructure of a building. The USB Q also features a transformer balanced output, providing the isolation required to eliminate earth loops/ground hum and other extraneous noise and distortion. Once in place, the USB DI-Q only requires touch button operation, and the simple user interface means that it is easy to use by non-technical operators.

The USB DI-Q is ideal for interfacing any USB equipped computer (especially notebook computers) with the balanced inputs of professional sound systems. The USB DI-Q installs as a generic plug-and-play USB audio device, requiring no special driver program installation on Mac OSX, Windows XP, 7/8/10 and includes a premium quality USB-A to USB-B cable.

The front panel features an overall playback level 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 LED status LED, summed (mono) output XLR with ground lift switch, and a 6.5mm/quarter-inch headphone output socket.
