3.4.4 How to use the MCS 263 as a delegate microphone unit
• Connect a microphone button to the “Mic” connection of the terminal strip .
• Connect a microphone to the microphone connection .
• You can connect an external LED via the terminal strip with the markings “LED -” and “LED +”.
• If you use a loudspeaker you can connect it to the “Speaker -” and “S” connection of the terminal
strip .
• The microphone button is used to turn the microphone on or off.
• The ready-to-speak status of the microphone is indicated by a red LED of the microphone itself or by a possible
external LED.
• In the “Free” mode each delegate can turn on his microphone with the microphone button.
• In the “Request” mode of the discussion system the microphone button is used to enter a request-to-speak. The
possible external LED and the LED ring of the gooseneck microphone will flash to indicate the request-to-speak.
When the microphone is released by the operator of the chairman microphone unit, the LED changes from
flashing to permanent illumination. In order to delete the request-to-speak the delegate can press the microphone
button once again.
• In the “FiFo” mode a microphone unit is turned off, when another one is turned on. A distance of approx. 30 cm
between the speaker and microphone is close enough.
• When the delegate speaks into his activated microphone, the signal is transmitted via all loudspeakers to the
other microphone units. The loudspeaker of the current speaker is automatically deactivated. Each microphone
unit features a limiter of 40 dB to avoid overrides when talking closely.
Important: If a headphone is connected to the microphone unit, it will be muted when the microphone is
activated.
• The microphone of the delegate microphone unit can be turned on voice-controlled, which allows an operation
without pressing the microphone button when the speaker speaks into the microphone.
The “Voice Activation” operating mode can also be selected with the chairman microphone unit.
• The delegate microphone units are turned off, when the delegate presses his microphone button or when the
chairman presses the “Clear” button.
This is also effected with the “Req” button in the “Request” mode, when the next speaker may speak.
In the “Voice” operation the microphone is automatically turned off after a pause of two seconds.
• The allocated time for the current speaker can be determined and displayed with the “Timer” function.
Depending on the setting the activated microphone unit can automatically be turned off after an audio warning
for instance or the exceeded talk time is displayed. In addition to standard functions, many settings can be allocated
and changed via configuration switches and programming. This provides a varity of operating modes and operation.
