Radial Engineering SGI Studio Guitar Interface System

Radial SGI Studio Guitar Interface is a transmit (SGI-TX) and receive (SGI-RX) pair of modules that allows a guitar signal to travel across 500 feet of balanced cable to a distant amplifi er. The SGI is a unity gain device that features 100% discreet Class-A circuitry for great sound and transformer isolation to eliminate ground loops.

For the studio, the SGI allows the guitarist to play in the control room while listening to the studio monitors. For live performance, the SGI allows amplifi ers to be located off stage while improving sound and reliability over wireless systems.

• Drive a guitar signal 300 feet without loss
• 100% discreet class-A electronics
• Drag Control pickup load correction
• Transformer isolated to eliminate noise
• Routes using standard balanced XLR cable

The Radial SGI 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 SGI allows a guitar signal to travel from the wireless system to a pedal board and amplifier. The SGI employs a proprietary drive and balancing circuit that is made up of two modules: the SGI-TX transmit module and SGI-RX receive module. The SGI-TX is active with 100% discreet class-A circuitry and Drag™ 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 artifact. Best of all, the SGI is plug & play easy to use and comes equipped with power supply.
