Central unit conference system. The DMU 6100 the heart of the system allowing the direct connection of up to 60 microphone sets on two lines. Specific tools are available on the DM 6100 to test the correct wiring and operation of the system to help installation and maintenance. The status is available on the LCD, including advice of the type of consoles connected. From the front panel of the main unit LCD, function buttons and LEDs help the installer and the user in adjusting all the parameters and volumes, while a speaker and a 1/4 ” jack work as audio monitoring.FeaturesTwo universal inputs for connecting any additional sources such as a wireless microphone or a lectern microphone or any other complementary device, even a mixer-preamplifier.Two inputs can be configured in different ways; for instance they can be mixed with the system audio, have priority on system microphone sets, one mixed and one priority etc.Dedicated IN and OUT connections are available echo-free for the link to a teleconference system.VOX operation or command operation are availableThe command switch can be programmed to work as FORCED-ON or FORCED-OFF always through configuration menuREC-PLAY input and outputs associated to a switch allow the connection of any recorder/player.4 additional Auxiliary Outputs are available for the independent recording of the 2 universal inputs and each of the 2 lines of microphone setsPlay inputInput level : - 7 (nominal) ; +12 (max) dBuInput impedance: 9 KFrequency Response: 50 ÷ 20 Hz ÷ kHzSignal / noise ratio: dBA 85MIC/LINE InputsGain range control: 40 dBFrequency Response: 50 ÷ 20 Hz ÷ kHzInput impedance: (Bal) 20 / (Unbal) 9 KPhantom power voltage/current: 23 VHigh-pass filter: 12 dB / oct (- 3dB cut @ 100 Hz)Vox threshold: -14 dBu ("line" input; nominal gain)Mic input level: -54 ÷ -14 dBuSignal / noise ratio: 65 dBALine/Mic+ Phantom input level: -27 ÷ +13 dBuSignal / noise ratio: 85 dBATeleconf IN/FROM InputInput level : -7 (nominal) ; +12 (max.) dBuInput impedance: 8 KFrequency response: 50 ÷ 20 Hz ÷ kHzSignal / noise ratio: 85 dBAINSERT IN MIC unit speakerInput level: -4 (nominal); +11(max.) dBuInput impedence: 20 KSignal / noise ratio: 80 dBAOutput sectionOutput level: -7 (nominal) ; +10 (max.) dBu (A & B output)Output level: 0 (nominal) ; +20 (max.) dBu (Main output)Signal / noise ratio: 90 dBA (A & B output)TELECONF.
