Radial Engineering SGI TX Stereo Instrument Line Driver

The Radial Engineering SGI Stereo TX is the transmitting half of a high‑performance stereo line‑driver system that sends two unbalanced guitar signals up to 100 metres (300 ft) over a single Cat‑5 Ethernet cable, draws power from any 9‑18 V supply and incorporates premium Jensen transformers for authentic tone.

Classic Foundations Enhanced with Modern Features

Radial’s original SGI transmitter offered clean mono signal delivery; the SGI Stereo TX expands that legacy by providing true stereo output, locking RJ45 etherCON connectors compatible with Neutrik, and a robust metal chassis. The updated unit retains the simple 9‑18 V power flexibility while adding a compact layout that fits neatly on pedalboards or rack shelves.

Studio‑Focused Connectivity

In a recording setting the TX accepts two ¼‑inch instrument cables from pedals, pedalboards or amp modelers, then converts the pair into a balanced stereo signal that travels over a single Cat‑5 cable to the RX in the control room. Engineers benefit from reduced cable clutter, zero latency and preserved dynamic response, eliminating the need for multiple XLR runs.

Stage‑Ready Performance

For live venues the TX balances each channel before transmission, protecting high‑impedance guitar signals from capacitance loss and lighting‑induced noise. Musicians mount the TX near the pedalboard and run a single Ethernet cable to remote cabinets, isolation boxes or quiet backstage rooms, gaining reliable stereo coverage across large stages.

Flexible Routing and Integration

The TX plugs directly into existing Ethernet infrastructure, allowing complex signal chains such as a wireless receiver → classic SGI TX → SGI Stereo TX → SGI Stereo RX for dual‑amp configurations. Its lock‑in etherCON connector secures the cable against accidental disconnects, while the design accommodates both touring rigs and permanent studio installations.

Power Versatility

The transmitter operates from any external supply between 9 V and 18 V, giving users the freedom to choose battery packs, pedalboard power modules or wall adapters without sacrificing performance.
