  • Features electrically isolated XLR I/O, a direct throughput with ground lift, and 2 transformer-isolated outputs. Has a 30dB pad, delivers 48V DC phantom power for microphones, has a ground lift, and has common mode noise rejection up to -100dB at 60Hz. Features a standalone housing with 14-gauge, I-beam steel frame with baked enamel finish and an innovative bookend cover. It also uses a Jensen JT-MBD mic bridging transformer. The JT-MBD features a 1:1:1 with dual secondary windings to allow dual isolated outputs. This allows the JS-3 to be equipped with a main direct-out for FOH and 2 isolated outs for monitor mix and broadcast feed.
