Get Your Laptop Connected to a Pro Audio System

Radial Engineering USB-Pro is a stereo USB laptop DI that provides high definition conversion and a simple plug-and-play solution for connecting your Mac or Windows computer to your PA system or mixer. Additionally, an integrated headphone amplifier allows convenient signal monitoring on the DI.

USB-Pro features two balanced 3-pin XLR outputs that can feed mic or line level inputs thanks to the unit's convenient level control. Auto-sensing USB input automatically configures USB-Pro for digital input streams with resolutions up to 24-bit / 96 kHz. USB-Pro is powered by USB, so there's no need for batteries, phantom power or bulky power adapters. Activate the mono switch to check phase, reduce mixer channel count, or simplify signal duplication on the two XLR outputs.

If the hum or hum is caused by ground loops, you can use a side switch to insert an isolation transformer into the signal path. This is complemented by a ground lift switch that raises pin 1 of the XLR output to further reduce the effects of interference.

Heavy-duty 14-gauge steel construction combined with Radial's bookend design ensures reliability on the road, while anti-skid pads provide mechanical and electrical isolation.
