SGI-44 Guitar Signal Extender
Studio Guitar Interface For JX-44
The SGI-44? is a line driver for guitars and basses that connects to the JX-44 to allow a remote pedalboard to be connected without signal loss or noise.
Balanced line driver for JX-44 guitar & amp switcher
Send signal over 100 meters (300ft) without loss
100% discrete class-A circuit with Drag control
Bidirectional send & receive effects router
Connect to your pedalboard remotely
The SGI-44 can send guitar signals over long distances without signal loss or noise, with built-in send and receive functions for bidirectional signal routing. When used in conjunction with the JX-44 guitar and amp switcher, it allows you to keep your pedalboard at your feet on stage, while instrument switching and amp control is managed remotely by your stage tech. A pair of SGI-44s can also be used together to extend the effects loop of your amplifier to any point on stage, so you can keep your favorite pedals connected to the amp's effects loop no matter how far away your amp is located. The SGI-44 takes care of all the balancing, buffering, and impedance matching to ensure your signals are delivered without noise or distortion.
SGI-44 Specifications
When used in combination with the JX44 the optional SGI-44 can either be used as a bi-directional long haul effects loop or as a single ended driver from a guitar to the JX44 and your amps. Balanced audio connections between the JX44 and SGI-44 allow distances up to 100 meters (300 feet) using standard XLR mic cable. This is accomplished using a proprietary hybrid active drive circuit with Jensen transformer isolation to transfer the signal between units without introducing noise or signal loss.
