Thanks to its half-supercardioid pickup pattern, the MB-1 greatly reduces ambient noise and pickup of room reverberation. The result is a clearer sound. The MB-1 must be used with an MB-100 or MB-200 interface (not included). The interface performs these functions: • Powers and equalizes up to four mics. • Provides programmable switching to turn the mic on or off if desired (switches not provided). • The MB-200 interface also has remote switch sensing via an optical coupler. • Pluggable microphone inputs. • Provides balanced outputs from the interface.
