The SGI is a powerful line driver system for guitar and bass that takes an unbalanced instrument signal and allows you to drive it via a conventional balanced XLR cable over distances of up to 100 meters—completely free from noise or signal loss.

The SGI system is ideal for large stages, transmitting high-impedance instrument signals without tonal loss over long cable runs. Interference from lighting systems and long cable runs is reliably prevented perfectly suited for isolation cabinets, amplifiers beneath the stage, or separate quiet rooms.

Additionally, the SGI system facilitates easy signal routing between wireless units, pedalboards, and amplifiers. With a second unit, the signal can be routed back to the amplifier, completely free of noise and interference, regardless of distance.

In the studio, the SGI system also excels: guitarists can sit in the control room, monitor their sound via studio monitors, and remotely operate a distant guitar amplifier located in the recording room.

Key Features:

  • Balanced line driver for guitar and bass
  • Send signal up to 100 meters without loss
  • Jensen transformers for optimal sound quality
  • Delivers natural tone to off-stage amplifiers
  • Can be powered by standard 9V pedalboard power supplies

The SGI system consists of two components:

  • SGI-TX (Transmitter)
  • SGI-RX (Receiver)

The connection between TX and RX uses a standard balanced XLR microphone cable. The guitar plugs into the SGI-TX input, and the amplifier connects to the SGI-RX output—simple and effective.

The SGI line driver system incorporates premium Jensen transformers in both units (SGI-TX and SGI-RX). Jensen transformers provide improved isolation against hum and ground loops, broader and more uniform frequency response, reduced noise, and less distortion. Additionally, they optimize dynamics and deliver a superior signal-to-noise ratio, ensuring the audio signal is transmitted losslessly and authentically over long distances.

The SGI-TX comes standard with a 15V power supply but can also easily operate using standard pedalboard power supplies from 9V to 15V.

To further ensure tonal fidelity, the SGI-TX includes a "Drag" control for load correction. This allows precise adjustment of the input impedance to the instrument (guitar/bass), maintaining the natural tone and original playing feel.
