SGI TX

The Radial SGI Studio Guitar Interface is a signal transmission system designed for extending high-impedance instrument signals up to 300 feet using balanced cable. This interface consists of the SGI-TX transmitter and SGI-RX receiver modules. The SGI maintains unity gain throughout the signal path and uses 100% discrete Class-A circuitry, providing low-noise operation. Transformer isolation is included to eliminate ground loop hum and maintain signal integrity over long cable lengths. The SGI-TX transmitter module is powered via an external AC adaptor. **Features:** - High-impedance instrument interface for long-distance cable runs (up to 300 feet) - Discrete Class-A circuit design for low noise and transparent audio performance - Transformer isolation to eliminate ground loop noise - Unity gain signal transmission - Includes transmit (SGI-TX) and receive (SGI-RX) modules - SGI-TX powered by external wall adaptor **Search terms:** guitar interface, Radial effects pedal, unity gain pedal, transformer-isolated interface, class-A instrument preamp, long cable run guitar interface
