The Crown MB-100 is a low profile, surface mountable power interface and switcher. The MB-100 is designed to accommodate up to four MB-1, MB-2 or MB-4/E boundary microphones via 2 input terminal blocks using screw terminal input connectors. Two additional terminal blocks are used for wiring on / off switches (sold separately) for complete control over each microphone. A programmable 4-position switch assigns all external switches to one of four functions. Momentary On, Momentary Off, Push-On and Push Off are all assignable. Low cut filter and gate functions are provided and globally switched to all microphones. The MB-100 provides 18 to 48V DC phantom power and features a durable screw mountable enclosure.
