Radial USB Pro

Radial USB-Pro - High-Resolution Stereo USB Laptop DI

• High-Performance 24bit/96k Stereo Direct Box: The Radial USB-Pro is a high-resolution stereo direct box designed to convert sound files from a laptop computer and deliver them with exceptional clarity and detail.

• Plug & Play Convenience: Automatically installs without the need for drivers, ensuring seamless compatibility with popular operating systems including Mac OSX, Windows XP, Vista, and Windows 7.

• Built-In Headphone Amplifier: Monitor digital-to-analog conversion with the built-in headphone amplifier to ensure accurate signal transfer and conversion.

• Balanced Lo-Z Outputs: Equipped with balanced low-impedance (Lo-Z) outputs, the USB-Pro offers professional-grade audio quality.

• Switchable Isolation: Two side-access switches allow you to insert isolation transformers into the signal path, effectively eliminating hum or buzz caused by ground loops.

The Radial USB-Pro is your gateway to high-resolution stereo audio conversion, designed to streamline the process of transferring sound files from a laptop computer to a PA system, recording setup, or broadcast mixing console. With its plug-and-play functionality, the USB-Pro automatically configures itself for use with various operating systems, making it incredibly user-friendly and eliminating the need for special drivers.

Unlike devices restricted to 16-bit, 44.1kHz conversion rates, the USB-Pro stands out with true 24-bit, 96kHz stereo converters. This elevated performance provides more headroom and greater detail, eliminating the necessity for additional sound cards or separate converters when transferring files. This not only simplifies your workflow but also enhances audio quality in busy production environments.

Connecting your laptop to the USB-Pro is effortless, thanks to the USB type-B port—the pro-audio standard for digital connections. To ensure that digital-to-analog conversion is accurate, a built-in headphone amplifier allows you to monitor the signal as it's downloaded and converted. Additionally, a mono-sum switch is available to check for phasing or facilitate signal distribution to two outputs if desired. You can easily set the output volume control to your preferred level.

In situations where ground loops introduce hum or buzz, two convenient side-access switches let you insert isolation transformers into the signal path to block stray DC voltage offsets effectively. Furthermore, a ground lift switch is provided, which lifts pin-1 on the two XLR outputs, reducing susceptibility to noise.

The Radial USB-Pro is built to withstand the rigors of professional touring, featuring Radial's unique book-end design that protects switches, connectors, and controls from damage. Inside, the time-tested I-beam construction prevents the internal PC board from torquing, ensuring long-term reliability. A full bottom no-slip pad not only provides mechanical isolation but also electrical insulation for your peace of mind.

Elevate your audio conversion experience with the Radial USB-Pro—a high-resolution stereo USB laptop DI designed for ease of use, uncompromising audio quality, and professional reliability.
