Quinta MU 33

DESCRIPTION

The Quinta MU 33 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. Additionally
the unit features two buttons to adjust the level on the headphone
output. The Revoluto microphone array technology with integrated
microphone capsules provides a so-called corridor characteristic
which ensures a wide range of good voice quality. The speaker can
move freely, i.e. can stand up or sit down, can move his/her head
and move towards or away from the microphone unit. 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 strips on both sides of the
housing.
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 priority
button the switched on delegate microphone units are switched off.
The delegates can switch on their microphone again, when the
chairman has switched off his.

Priority “Mute”

When the chairman switches his microphone on with the
priority button 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 “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.

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 must be 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 set for all
microphone units.

The volume of the loudspeaker is adjusted and can be controlled
with the Quinta control unit or a media control system.

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 an operation of
the microphone unit of 20 hours depending on the amount of
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 also be displayed. The charging time of a completely empty
battery is max. 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
microphone button once. There are various ways to switch off the
microphone unit:

1. Press the microphone button for 3 seconds.

2. Press the standby button of the Quinta 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
microphone unit will be switched off.
