Radial Engineering SGI Stereo TX/RX Stereo Instrument Line Driver System

The Radial Engineering SGI Stereo TX/RX is a high‑performance two‑channel line‑driver system that transmits unbalanced guitar signals up to 100 metres (300 ft) over a single Cat‑5 Ethernet cable, powered by 9‑18 V supplies and equipped with premium Jensen transformers for pristine tone.

Classic Design Meets Modern Enhancements

Radial’s original SGI concept delivered clean, low‑noise signal transmission for mono instruments; the SGI Stereo expands this legacy with true stereo capability, locking RJ45 etherCON connectors compatible with Neutrik, and a 180° polarity‑reverse switch on the receiver. The updated unit retains the rugged metal chassis and simple power‑supply flexibility while adding L/R thru‑puts on the RX for local amp connections, allowing musicians to keep a compact footprint on stage or in the studio.

Studio‑Ready Connectivity

Guitarists can plug two ¼‑inch instrument cables into the TX, run a single Cat‑5 cable to the RX, and monitor the full stereo output through studio monitors without latency. The system eliminates the need for bulky XLR runs, reduces cable clutter, and preserves the natural dynamics of pedals, pedalboards, and amp modelers.

Stage‑Optimised Performance

On large venues the SGI Stereo combats capacitance‑induced tone loss and lighting‑induced interference by balancing each channel before transmission. Musicians can place the TX near the pedalboard and locate the RX up to 100 m away, feeding isolated cabinets, under‑stage amps, or quiet rooms while maintaining signal integrity.

Versatile Routing Solutions

The SGI Stereo integrates seamlessly with existing Ethernet infrastructure, enabling complex routing chains such as a wireless receiver → classic SGI → SGI Stereo TX/RX pairs for dual‑amp setups. Its robust construction tolerates touring rigors, and the polarity‑reverse switch simplifies phase alignment across multiple cabinets.

Power Flexibility

Both units accept any external power supply ranging from 9 V to 18 V, granting users the freedom to choose battery packs, pedalboard supplies, or wall adapters without compromising performance.
