Radial USB-Pro – Features
- High performance 24-bit digital audio converter
- Ready to use without the need of a driver
- 3.5mm analog headphone output to check signal
- Balanced Lo-Z outputs with switchable isolation
Radial USB-Pro features 24 bit resolution for optimal signal transfer and maximum dynamic range. As with all Radial products, it is designed to be ‘plug & play”: one merely plugs in and the USB-Pro powers up and is automatically recognized by the computer without the need of external drivers. A built in headphone provides a ready means for checking the audio and switchable isolation transformers help eliminate hum and buzz caused by ground loops that are often encountered in multi-media setups.
Connection to a computer is accomplished through a standard USB type-B port. Digital-to-analog conversion can be monitored on headphones through the 3.5mm analog output to check signal quality and level before connecting to a sound system. A mono-sum switch may be engaged to check for phasing or for connection to a mono system. Should hum or buzz caused by ground loops be encountered, two recessed side-access switches allow the user to insert isolation transformers into the signal path. To further reduce susceptibility to noise, this is augmented with a ground lift switch that lifts pin-1 on both XLR jacks.
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 cause premature part failure. Finally, a full bottom no-slip pad provides mechanical isolation and electrical insulation to ensure quiet operation.
