CONNECTING THE SGI-44

Begin  by  placing  the  SGI-44  at  your  remote  pedalboard  and  connecting  the 

included 15VDC power supply. Once connected the POWER LED on the SGI-44 

will illuminate.

Next, Connect your effect pedals to the SGI-44’s ¼” input and output jacks using 

standard guitar cables. The SGI-44 includes a dedicated Tuner output should 

you wish to connect a tuner pedal for use on stage. 

Then make the balanced connections between the JX44 and the SGI-44 using 

XLR mic cables. The TX (transmit) output from the JX44 connects to the RX 

(receive) input on the SGI-44

.

 The SGI Loop is completed by connecting the TX 

output from the SGI-44 to the RX input on the JX44.

Once your cables are connected press the SGI ON switch on the rear panel of 

the JX44. An LED below this switch will illuminate to show the SGI Loop is active 

and  you  will  hear  your  pedalboard  effects  across  any  active  amplifier  output, 

regardless of whether the EFX Assign switch is set to L, R, or DRY. 

Both the JX44 and the SGI-44 are transformer isolated to eliminate noise caused 

by ground loops. If you hear hum or buzz after connecting and testing the SGI 

Loop, try toggling the Lift switches on both the SGI-44 and on the rear panel of 

the JX44. 

EXAMPLE: WIRELESS GUITARS AND A REMOTE PEDALBOARD 

In this application the JX44 is located near the player’s wireless receivers and guitar amplifiers. The SGI-44 and 

JR-5 reside on the player’s pedalboard. The signal starts at the guitar through the wireless link to the receiver. From 

the receiver it flows into the JX44 inputs. At this point the SGI Loop sends the signal out to the pedals and back 

again via the SGI-44 interface. The artist can enjoy the freedom of the wireless guitar and have their pedals out front 

at their feet along with the JR-5 remote to control amplifier or instrument switching.
