Radial's SGI (Studio Guitar Interface) instrument line driver system allows you to take any unbalanced instrument signal and drive it up to 300 feet with pristine clarity and zero unwanted noise. The SGI-TX is the system's transmitter unit, boasting a premium Jensen transformer for optimal sonic performance. What's more, the SGI-TX comes equipped with a handy Drag control, giving you the power to dial in the proper load for your guitar's pickups. Finally, while both the SGI-RX and the SGI-TX can be powered via their included 15-volt power supply, the system has been updated to accommodate the power from scores of pedalboard-standard power supplies. Whether you're tracking in the control room or routing your signal to a far-off backline, Radial's SGI system ensures your instrument signal always performs to the highest level possible.

Fueled by top-quality Jensen transformers

Boasting premium-quality components from stem to stern, both the SGI-TX and the SGI-RX leverage top-class Jensen transformers. These transformers are a key component of the SGI ecosystem, converting your signal at both the beginning and end of the system and defeating hum before it can even begin. Furthermore, these industry-leading transformers ensure a wide and flat frequency response with diminished noise and distortion, superior dynamic range, and an optimized signal-to-noise ratio.
