Crown MB200

 Designed to accommodate up to four microphones, the MB-200 Interface is a low-profile electronics package easily mounted beneath a table-top. It works with MB-1, MB-2, and MB-4E microphones and provides four inputs, four outputs and four remote switch inputs. Each switch input can be programmed for either push-on/off, momentary on, or momentary off operation. In the off position, the MB interfaces provide 70 dB attenuation at the microphone output ensuring absolute quiet even when multiple microphones are in use.  The MB-200 also provides four external switch closures via optical couplers and requires external 18-48 volt phantom power.
