The Radial SGI TX 9V is the active transmitter module of the SGI system, designed to send a high-impedance guitar signal over long distances without noise or tone loss. It features a 1/4" instrument input, a balanced XLR output, and a Drag Control™ load correction circuit to replicate the natural tone and feel of connecting directly to a tube amplifier. Equipped with a premium Jensen transformer, it ensures excellent signal integrity and isolation. The SGI TX 9V can be powered by standard 9V to 15V pedalboard power supplies, making it convenient for integration into pedal setups. Its rugged steel chassis and compact design make it suitable for both studio and live performance environments.
