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.
