Radial Engineering SGI RX Stereo Instrument Line Driver

The Radial Engineering SGI Stereo RX is the receiving half of a high‑performance stereo line‑driver system that accepts a single Cat‑5 Ethernet cable and reproduces two balanced guitar signals up to 100 metres (300 ft) away, powered by any 9‑18 V supply and fitted with premium Jensen transformers for authentic tone.

Classic Reliability Combined with Modern Functionality

The original SGI receiver provided clean mono signal recovery; the SGI Stereo RX builds on that heritage by delivering true stereo output, locking RJ45 etherCON connectors compatible with Neutrik, and a 180° polarity‑reverse switch for effortless phase correction. It retains the rugged metal chassis and flexible power options while adding L/R thru‑puts that feed local amplifiers directly from the receiver unit.

Studio‑Centric Performance

In a recording environment the RX sits in the control room, receives the transmitted stereo pair via the single Ethernet link, and drives studio monitors or headphone mixes without latency. Musicians enjoy full stereo imaging from pedals, pedalboards, or amp modelers while the RX eliminates the need for multiple XLR runs and preserves the natural dynamics of the source gear.

Stage‑Optimised Capability

For live venues the RX delivers pristine stereo signals to remote cabinets, isolation boxes, or quiet backstage rooms. The locking etherCON connector secures the cable against accidental disengagement, while the 180° polarity‑reverse switch resolves phase issues that can arise when feeding separate amplifiers on opposite sides of a stage.

Versatile Routing and Integration

The RX works seamlessly with existing Ethernet infrastructure, allowing complex signal chains such as a wireless receiver → classic SGI TX → SGI Stereo RX for dual‑amp configurations. Its L/R thru‑puts provide immediate local amplification, meaning engineers can split the received signal between front‑of‑house and monitor mixes without additional hardware.

Power Flexibility

The unit operates from any external supply between 9 V and 18 V, giving users the choice of battery packs, pedalboard power modules, or conventional wall adapters while maintaining consistent performance.
