MaxBus eliminates the poor audio quality that results when a talker is picked up by more than one microphone. It does this by controlling the number of microphones that may activate for a single sound source. With MaxBus, one talker will activate only one FP410 channel, even if multiple microphones are “hearing” that talker.

Multiple miking
It’s somewhat like having multiple video cameras all fo- cused on the same subject. If these camera signal are com- bined, the result is a blurred image. When multiple micro- phones are open for a single talker, the result is a blurred audio signal. But it’s often not practical for someone to turn mics on when they are needed and off when they are not. The answer is the FP410 automatic microphone mixer.
The FP410 automatically attenuates (turns down) any mi- crophone not being used, greatly reducing the excess rever- beration and feedback problems associated with the use of conventional multiple microphone and mixer techniques. When a new talker starts to speak, the FP410 immediately se- lects and silently activates the most appropriate microphone. Shure IntelliMix electronic signal processing enables the FP410 to provide clear, natural voice pickup. The FP410 sig- nificantly reduces the problems of “boomy” or “muddy” sound, insufficient sound level (because of feedback or “howling”), and operator errors. In fact, operator errors are virtually elimi- nated because the FP410 needs no operator or technician for continual
The FP410 has numerous applications in video production and audio recording, broadcasting, and sound reinforcement. In any speech pickup application where multiple microphones are required, the FP410 dramatically improves audio quality. Switching from manual to automatic operation allows an indi- vidual talker’s voice to rise above the background noise and reverberation to become clearer and more intelligible.
Each FP410 handles up to four microphones or
