FORUM 6000 Discussion System Central Unit The DMU 6100 serves as the core of the system, enabling direct connection of up to 60 microphone sets across two lines. The DM 6100 includes specific tools for testing system wiring and operation to aid in installation and maintenance. The LCD displays system status, including the type of consoles connected. The front panel features an LCD, function buttons, and LEDs for adjusting parameters and volumes. Additionally, a speaker and 1” jack provide audio monitoring. Features: - Two universal inputs for connecting additional sources like wireless microphones, lectern microphones, or mixers/preamps. - Inputs can be configured in various ways, such as mixing with system audio or having priority over microphone sets. - Dedicated echo-free IN and OUT connections for teleconference system linking. - VOX or command operation available. - Programmable command switch for FORCED-ON or FORCED-OFF settings. - REC-PLAY inputs and outputs for recorder/player connection. - 4 Auxiliary Outputs for independent recording of inputs and microphone lines.
