The Radial SG1 studio guitar interface allows a guitar signal to travel 100 meters (328 feet) over a standard balanced XLR mic cable.

This enables the guitarist to play through a distant amplifier while listening to the performance in the control room. On large stages, the Radial SGI allows a guitar signal to travel from the wireless system to a pedalboard and amplifier. The Radial SGI employs a proprietary drive and balancing circuit that is made up of two modules: the Radial SGI-TX transmit module and Radial SGI-RX receive module. The SGI-TX is active with 100% discreet class-A circuitry and Drag‚Ñ¢ control load correction to ensure the most natural sound. The SGI-RX is completely passive. To eliminate hum and buzz caused by ground loops, each module is equipped with isolation transformers that are wired in opposing directions to counteract any artefact. Best of all, the Radial SG1 is plug & play easy to use and comes equipped with a power supply.
