ARX USB DI VC Plug and Play digital to analog pro audio interface 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-VC - everything that the original USB DI was, with the addition of an output 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 the output level can be modified quickly 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 volume control allows the USB DI-VC to be used without a mixer. This is a very useful option when driving active loudspeakers from a laptop - the level control lets you reduce the level instantly to suit the required SPL, while still retaining an excellent signal-to-noise ratio. Plug and Play The USB DI-VC installs as a fully compatible generic USB audio device, requiring no special driver program installation on Mac OSX, Windows XP, 7/8/10 The rear panel has a Type B USB input connector while the front panel has an Output Level control and two transformer balanced analog audio XLR Line out connectors for connecting to any standard balanced analog input. A status LED on the rear panel next to the USB Input indicates that the USB DI-VC is connected and operating. The USB DI-VC is housed in a heavy duty all-steel chassis finished in attractive matt textured powdercoat, with hardwearing epoxy screen printing and slip resistant rubber pads. 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-VC is available in Dual Channel format, includes a premium quality USB-A to USB-B cable, and is hand made in Australia USB-DI VC Specifications Input Connector USB type B port Codec 24 bit High Resolution, 44.1 and 48 KHz Output Impedance 300 Ohms Transformer Balanced Output Level User variable from 0dB down to infinity (off) Output Noise USB - System dependent ISO transformer - Environment sensitive Frequency Response 20 - 20 KHz 0.5 dB Power Operating current via USB Port 80mA Output Connectors 2 x Male XLR, wired Pin 2 + Hot, Pin 3 ?
