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.
Using the SGI-44 on a concert stage
Routing the guitar signal from the wireless system to the pedals and amps is usually problematic due to induced electromagnetic fields and noise caused by ground loops. The SGI-44 solves the problem with a 100% isolated signal path and easy connections. Set one SGI-44 near the wireless receiver and a second at the pedalboard. Connect using XLR cables and you are set to go!
Using the SGI-44 in the studio
The Radial SGI-44 lets you play guitar using your 100 watt amp in an isolation room while you listen to the performance in front of your studio monitors. Connect your guitar to the first SGI-44 and run an XLR cable to a second unit using the studio XLR tie lines. Connect to your amp at the other end. Adjust the Drag Control to correct the load and optimize the signal for the right feel and you are set to go!
Using the SGI 44 with the Radial JX44
The Radial JX44 comes with a built-in SGI-44 to make distant effects routing easy. Simply connect the JX44 to the SGI-44 using a pair of XLR cables to route the signal from the wireless receiver bank out to the pedals and back. The SGI-44 lets you incorporate a pedalboard as if connected directly yet does so without noise or signal loss.
