The RCF MMU 3100 master unit includes all the features necessary to set-up a meeting for up to 80 microphone sets.  Recording output and playback input are present as well, together with a dedicated input and output for teleconference system interfacing.

The unit is able to provide 80W on its 100V or 70V output for the connection of additional sound reinforcement speakers present in the room. One line level output is available too, for the link to an independent sound reinforcement system.

User controls are on front panel and include volume levels for inputs and powered outputs, directed to the reinforcement speakers integrated in each microphone console and to the ones connected to the amplifier direct output.

Two devices MMU 3100 can be linked through a dedicated port, to expand the number of the delegate microphones to 160.
