The Iso-Max MS-2XX is a passive two channel mic splitter that lets you take a microphone signal and send it to two consoles at the same time. The design begins with a rugged flanged steel enclosure for easy mounting in a rack or inside a NEMA enclosure. Standard gold plated 3-pin XLR-female inputs and XLR-male isolated outputs. Removable screw-down terminal block as a direct output and phantom power return for condenser mics. Inside are two premium Jensen mic bridging transformers equipped with dual Faraday internal shields and external MuMETAL® cans. These isolate the two consoles, eliminating ground loops while reducing common-mode noise by as much as 130dB. This is augmented with an 8 position DIP switch that lets you optimize grounding and RF filtering to suit your specific installation needs.
