Description
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. =+= Technical Specification
