Orbis MU 23

DESCRIPTION

The Orbis MU 23 chairman microphone unit is equipped with one
microphone button, clear button and configurable function button
in the housing. The microphone button is used to turn the micro­phone on or off. The ready-to-speak status of the microphone is
displayed by the red LED on the gooseneck microphone and the
green backlit microphone button.
The chairman does not depend upon the limited number of open
microphones (NOM). Each chairman microphone unit is perma­nently allocated to a channel (max. 8) in the system.

When using the clear button all activated delegate microphones are
turned off.

When using the function button the chairman can intervene into
the discussion and mute or clear all activated delegate microphones
depending on the system configuration.

Depending on the configuration of the Orbis CU control unit one of
the following operating modes is possible:

Normal

Each participant can turn on his/her microphone unit until the
maximum number of open microphones is achieved.

FiFo

Each participant can turn on his/her microphone. If the selected
number of open microphones (NOM) is exceeded, the microphone
of the participant who turned on his/her microphone first is turned
off when another participant turns on his/her microphone.

Voice-controlled Activation

The microphone is automatically turned on when the participant
speaks into it, until the number of open microphones is achieved.

The function button is configured via the Orbis CU control unit. The
following functions are possible:

Normal:

All activated delegate microphones are cleared and the microphone
of the chairman microphone unit is turned on. The function button of
the chairman microphone unit is illuminated red. The delegates can
turn on their microphone only when the priority mode has been
finished. The chairman microphone which has automatically been
activated, remains active until the chairman turns it off by using the
microphone button.

Mute:

All active delegate microphones are muted when the chairman is
speaking. The function button of the chairman microphone unit is
illuminated red. When the priority mode is finished, all delegate

microphones that had been active before, will be activated again.
Microphones which have been activated by voice control, remain
deactivated after finishing the priority mode. The chairman micro­phone which has automatically been activated, remains active until
the chairman turns it off by using the microphone button.

The microphone unit’s design follows the UN convention on the
rights of persons with disabilities. It includes silicone buttons with
tactile feedback and Braille marking. A headphone or induction loop
for people with a hearing aid can be connected to the mini jack
output. The volume of the headphone is adjusted with a separate
control. Furthermore, by pressing the volume control the participant
can toggle between two channels (e.g. original and 1 AUX-IN e.g.
foreign language channel).

The integrated loudspeaker reproduces the audio signal of the
whole conference system. When the participant turns on the
microphone, the loudspeaker isl automatically turned off to avoid
feedback.

The microphone units are connected in a daisy chain to the Orbis CU
control unit, i.e. the first microphone unit is connected to the
control unit, the second microphone unit is connected to the first,
the third microphone unit to the second and so on. For connection
standard CAT5e cables (S/UTP, AWG 26 or better) are used. Thus,
one cable ensures the audio transmission, power supply and control.
The microphone units are very economical and use 1 watt at maxi­mum in operation at maxi- mum volume.

Connection to a control unit without redundancy

A maximum of 50 microphones can be connected to one of the
two lines of the Orbis CU control unit, i.e. a total of 100 micro­phone units can be operated with one Orbis CU control unit.

Connection to a control unit with redundancy

A maximum of 50 microphone units is connected in a ring to the
Orbis CU control unit, i.e. the last microphone unit is connected to
the previous microphone unit and the control unit. The redundancy
provides maximum reliablility. Should a defect in a cable occur at
one side of the microphone unit, the microphone unit will not fail
to operate, because it will still be supplied via the cable from the
other side. The cable in question or a defect microphone unit as
well can be replaced during operation without causing any
problems with the other microphone units.

The threads at the bottom of the microphone unit allow the unit to
be attached to a tabletop by using screws. In this way the micro­phone unit is protected against theft.

GM 31X Q GOOSENECK MICROPHONE

DESCRIPTION

The GM 31x gooseneck microphone is available as optional
accessory to connect to the microphone unit.
Due to the cardioid polar pattern this microphone has a high gain
before feedback and provides highest intelligibility of speech.
The LED ring displays the ready-to-talk status of the microphone.
Inside the microphone there is a filter to eliminate wind and pop
noise.
The microphone features the innovative Scudio™ technology,
making the microphones absolutely insensitive to wireless
communication devices such as mobile phones.
The microphone is mounted on a 6 mm thick gooseneck and due to
its mat black, non-glare surface almost invisible.

The following lengths are available:
GM 313 Q = 300 mm [11.81"]
GM 314 Q = 400 mm [15.75"]
GM 315 Q = 500 mm [19.69"]
