The Radial SGI 44 is a studio-quality bidirectional effects router that designed to take the output from a wireless receiver and run the guitar signal to the pedalboard and back. Two SGI-44s are used with one positioned at the wireless end, the other at the pedalboard.  Connection is made using standard XLR cables.

The first SGI-44 converts the unbalanced high-impedance guitar signal to a balanced low-impedance signal and the second reverses the process - thus allowing distances of more than 100 meters (300') without noise. To ensure optimal signal quality, the SGI-44 employs 100% hand-inserted discrete parts with Jensen isolation transformers to make up the class-A circuit. Although less efficient than the chip based AB circuits that are common with today’s ‘cost driven’ designs, single ended class-A circuits are preferred by audiophiles due to the lack of zero-cross distortion. These  deliver greater transparency and realism. To further improve the feel, the SGI-44 is equipped with Drag Control load correction. This allows you to 'dial in' the perfect load as if connected to a tube guitar amp using a standard guitar cable. To add versatility, the SGI-44 is equipped with a buffered tuner out for quick between song adjustments or can be used to split the guitar signal to a second signal chain if need be.

Built 'Radial tough' the SGI-44 is made in Canada using 14 gauge steel. An innovative I-beam internal frame protects the sensitive circuit board from outside stress which could torque the solder points and cause premature failure. Radial's innovative book-end construction creates recessed zones at each end that protect connectors, switches and controls from harm's way.

The Radial SGI-44 makes it easy to route guitar signals around a stage, in the studio or in a large venue while delivering the very best signal quality.

Radial Engineering SGI 44 Features:

  • Bidirectional long-distance 'send & receive' effects router
  • Drive guitar & bass signals beyond 100 meters
  • 100% discrete class-A circuitry
  • Works with the Radial JX44 guitar & amp selector
