SGI RX
Instrument Line Driver Receiver Only
The SGI-RX is the receiving unit of a high-performance guitar line driver system designed to transmit unbalanced instrument signals up to 100 meters (300 feet) without noise or signal loss. Ideal for studio use, it allows guitarists to play from the control room while their amp remains isolated in another space, preserving the instrument’s original tone. On stage, the SGI can connect to off-stage isolation cabinets or integrate seamlessly with wireless systems, pedalboards, and amplifiers.
This system consists of two modules: the SGI-TX (transmitter, sold separately) and the SGI-RX (receiver). The SGI-TX features 100% discrete Class-A circuitry and Drag™ control load correction for a natural sound, while the SGI-RX is completely passive. Both modules include isolation transformers wired in opposing directions to eliminate hum and buzz caused by ground loops.
For the complete SGI studio guitar interface, search for the Radial SGI. If you need just the transmitter, look for the Radial SGI-TX.
