Quinta MU 23
D
ESCRIPTION
The Quinta MU 23 chairman microphone unit is equipped with a
clear, function and a microphone button in the housing with which
the participant can switch his microphone on and off. The
chairman microphone unit does not depend on the maximum
number of simultaneous open microphones. Unlike the delegate
microphone units the chairman microphone unit is not controlled by
Automatic Channel Allocation, but has an extra transmitting
channel exclusively for the chairman. The ready-to-talk status of the
microphone is indicated by the red LED ring around the gooseneck
microphone.
Using the clear button all switched-on microphones of the delegate
microphone stations are switched off.
With the function button there are various configurations possible
via the “Quinta Conference” software:
Priority “Normal”
When the chairman switches his microphone on with the function
button and the priority programming “Normal” the switched on
delegate microphone units are switched off. Afterwards the
delegates can switch on their microphone and take part into the
discussion again, while the chairman’s microphone is still switched
on.
Priority “Mute”
When the chairman switches his microphone on with the function
button and the priority programming “Mute” the switched on
delegate microphone units are muted as long as the chairman is
speaking. If the chairman switches his microphone off, all delegate
microphone units that had been switched on before, are switched
on again.
Priority “Clear”
When the chairman switches his microphone on with the function
button and the priority programming “Clear” the switched on
delegate microphone units are switched off. The delegates can
switch on their microphone again, when the chairman has switched
off his.
“Function”
A command is sent via the RS 232, USB, TCP/IP serial interface from
the Quinta CU control unit and a programmed function is carried out
via a media control system for instance (e.g. light control). For the
other functions there is also a command sent via the RS 232, USB,
TCP/IP serial interface from the Quinta CU control unit
Command A/B
Two different commands according to the duration of the push:
< 1 second = command “Short press string” is transmitted
> 1 second = command “Long press string” is transmitted
These commands can be set individually with the “Quinta Conference”
software.
Audio Mute
An audio signal, e.g. from a wireless microphone, can be switched
off. This function can be combined with a “Clear” command to
switch off activated delegate microphones.
Depending on the configuration with the “Quinta Conference”
software the following operating modes are available:
Voice activation:
the microphone is switched on, when someone
speaks into it.
Push-To-Talk:
the microphone button is held down, while the
participant is speaking.
The integrated loudspeaker reproduces the audio signal of the
whole conference system. Depending on the audio signal routing in
the control unit the loudspeaker can reproduce other audio signals
such as a wireless microphone in the auditorium.
The parameters of the microphone unit are adjusted via PC by using
the “Quinta Conference” software. The parameters are adjusted
for all microphone units.
The volume of the loudspeaker is adjusted and can be controlled
with the Quinta CU control unit or a media control system. The
ducking level determines the attenuation of the loudspeaker level
when the microphone of the microphone unit is switched on.
Each microphone unit has its own address. An existing system can
be complemented at any time.
The DSSS transmission offers high immunity against unauthorised
listening with a 128-bit encryption. In addition to this, the conference
system including the appropriate microphone units can be protected
with PIN code (24-bit). A microphone unit that does not have the
correct PIN code will be identified by the control unit and switched
off immediately.
The integrated rechargeable battery allows a minimum operation
of the microphone unit of 20 hours depending on the participation
in the discussion. As soon as the remaining battery time is below a
certain threshold of 1 hour, the power on LED on the rear of the
microphone unit will flash or if the system is controlled by PC or a
media control system, the low battery capacity can be also
indicated. The charging time of a completely empty battery is
around 2.5 hours with the integrated processor-controlled charging
electronics. Depending on the use of the microphone unit the
charging time can be less.
As an option the microphone unit can be powered and charged by
a DC power supply adapter.
The microphone unit is switched on by briefly pressing the micro-
phone button once. There are several ways to switch off the
microphone unit:
1. Press the microphone button for 3 seconds.
2. Press the standby button of the MCW-D 50 control unit for
3 seconds to switch off all activated microphone units.
3. Switch off all microphone units via an RS 232 or TCP/IP
command from the PC or media control system.
4. Switch off the control unit; after approx. 3 minutes the micro-
phone unit will be switched off.
