ARX - Audibox USB DI-HP

Bus powered USB audio In, transformer balanced L-R XLR Out with the addition of a

Headphone Volume Control on standard and mini-jacks connectors to monitor the output



In response to many requests from users of our original USB DI who have been using it for specific applications, ARX is excited to present the new ARX USB DI-HP - everything that the original USB DI was, with the addition of a headphone output with its own level control. It is still a true Plug and Play digital to analog pro audio interface, removing the need to use any existing sound card outputs, but now its output level can be monitored quietly and accurately.


Naturally it still features full transformer balanced output isolation to eliminate earth loops / ground hum and other extraneous interaction noise and distortion.


The addition of the headphone output and control allows easy personal monitoring of the audio signal passing through the USB DI-HP without the need for Monitor Loudspeakers.


Plug and Play


The USB DI-HP installs as a fully compatible generic USB audio device, requiring no special driver program installation on Mac OSX, Win XP, Vista and Windows 7. 


The front panel has a Type B USB input connector and a Headphone Output Level control. While the USB DI-HP's Transformer Ground isolation provides low-noise operation, an Audio Ground lift switch is also fitted, to minimise/remove ground loop hum. Switch in or out as required.


A status LED on the front panel next to the USB Input indicates that the USB DI-HP is connected and operating.


The rear panel has both 6.5mm (¼ inch) and 3.5mm ((mini-jack) headphone outputs, and two transformer balanced analog audio XLR Line out connectors for connecting to any standard balanced XLR analog input.


The USB DI-HP is housed in a heavy duty all-steel chassis finished in attractive matt blue textured powdercoat, with hardwearing epoxy screen printing and slip resistant rubber basepad. It is ideal for interfacing any USB equipped computer (especially notebook computers) with the balanced inputs of professional sound systems.


Security features include Kensington®-type computer lock slot and optional bracket kit for under-table mounting.


The USB DI-HP is available in Dual Channel format, includes a premium quality USB-A to USB-B cable, and is hand made in Australia.
