The Radial SGI Stereo is a professional stereo instrument line driver system designed to send unbalanced instrument signals—such as guitars, keyboards, or stereo pedalboards—over long distances without noise or tone loss. It is ideal for studios, live stages, and remote amplifier setups.

The system consists of a transmitter (TX) and receiver (RX) and uses a single standard Cat5 Ethernet cable to carry balanced analog stereo audio up to 100 m (300 ft). High-quality Jensen transformers ensure exceptional sound clarity, wide frequency response, and low distortion.

The TX unit features stereo inputs and Thru outputs for feeding local amplifiers, while the RX unit includes polarity reverse and independent ground lift switches to eliminate hum and phase issues. The SGI Stereo can be powered from 9 V to 18 V DC, making it easy to integrate into pedalboard and professional audio systems.
