This 24/96 stereo DAC/DI is built for the road. An easy way to get your digital music from any USB equipped device to XLR and headphones.
Radial Engineering Ltd is pleased to announce the USB-Pro, a high-resolution stereo direct box designed to convert sound files from a laptop computer and seamlessly transfer them to a pair of balanced audio outputs to feed a PA, recording or broadcast mixing console.
According to Radial President Peter Janis: “For years, Radial customers have been asking us to get into the digital world. We have hesitated due to lack of clear standards and challenges with respect to interfacing with computers. But with the recent advent of self-configuring USB ports, we feel the time is right to finally get involved and the USB-Pro is the first Radial product to sport digital connectivity.”
Made to be plug & play easy to use, the USB-Pro automatically configures itself for use with all popular operating systems including Mac OSX, Windows XP, Vista and Windows 7, thus eliminating the need to load special drivers. And unlike devices that are limited with 16 bit, 44.1 kHz conversion rates, the USB-Pro elevates the performance with true 24 bit, 96 kHz stereo converters to deliver more headroom and greater detail. This eliminates the need for additional sound cards or separate converters when transferring files, further streamlining production in busy work environments.
Connection from the laptop is done via the pro-audio standard USB type-B port. Digital-to-analog conversion is monitored with the built-in headphone amplifier to ensure the signal is being properly downloaded and converted. A mono-sum switch may be engaged to check for phasing or facilitate signal distribution to two outputs should this be preferred. One simply sets the output volume control to suit. Should hum or buzz caused by ground loops be encountered, two set & forget side-access switches let you insert isolation transformers into the signal path to block stray DC voltage offsets. To further reduce susceptibility to noise, this is augmented with a ground lift switch that lifts pin-1 on the two XLRs.
As with all Radial products, the USB-Pro is designed to handle the rigors of professional touring. Our unique book-end design creates protective zones around the switches, connectors and controls to keep them out of harm's way. Inside, our time-tested I beam construction assures the sensitive internal PC board will not torque which could otherwise cause premature part failure. Finally, a full bottom no-slip pad provides mechanical isolation and electrical insulation, further advantaging the user.
The Radial USB-Pro is a serious digital to analog interface that effortlessly delivers great audio for the most demanding audio engineer.
The USB-Pro is now shipping and retails for $220.
