The Radial Engineering SGI is a high performance line driver that takes an unbalanced guitar signal and allows you to drive it as far as 100 meters (300ft) without noise. In the studio, it allows the guitarist to sit in the control room and connect to a distant guitar amp. On stage, the SGI can be used to play the guitar amp using off-stage isolation cabinets or be used to manage guitar signals to and from wireless systems, pedalboards and amplifiers. The SGI consists of two boxes: the SGI-TX transmitter and the SGI-RX receiver. The connection between the TX and RX is made using a standard balanced XLR microphone cable.


  • Balanced line driver for guitars and bass
  • Send signal over 100 meters (300 feet) without loss
  • 100% discrete class-A with Drag Control™
  • Delivers pure sound without artefact
