Description The MMU 3100 master unit provides complete control for a conference system accommodating up to 80 microphone kits. It features input with volume control and voice equalization, additional universal input via XLR and terminal block, and phantom power for microphones. The unit offers input/output for external recorder/player systems with dedicated controls and EQ, plus support for teleconferencing and broadcasting systems. An integrated 80-watt amplifier powers both the console speaker and constant voltage speaker outputs. A second MMU 3100 can be cascaded to extend capacity to 160 microphones. With flexible input/output configurations, built-in processing, and robust protection features, it is an ideal solution for scalable conference setups.
