Radial Engineering SGI TX/RX Instrument Line Driver System
The Radial SGI is a professional-grade line driver system designed to extend unbalanced guitar signals up to 330 feet without noise or signal degradation. Ideal for studio and stage applications, the SGI (studio guitar interface) system consists of a transmit (TX) module and a receive (RX) module, connected via a standard balanced XLR microphone cable for reliable long-distance signal transmission.
The SGI TX transmitter is an active device that requires power, operating with the included 15 VDC power supply or a standard 9 to 15V pedalboard power source (center-pin negative or positive). The SGI RX receiver is fully passive, requiring no external power.
To ensure pristine signal integrity, the SGI is equipped with premium Jensen isolation transformers at both ends, effectively eliminating ground-loop noise that can occur when connecting devices powered by different electrical circuits. The rugged 14-gauge steel chassis with welded I-beam construction provides exceptional durability, while the bright yellow finish ensures high visibility for quick identification in studio or live environments.
