• The charger has been designed for charging the rechargeable batteries in the Quinta microphone stations. Only charge
Quinta microphone units and no other battery operated equipment. The batteries could explode and injure you or damage the equipment.
• If you use the charger with accessories which have not been developed for it, this could result in a fire, an electric shock or physical injury.
• Never try to repair the charger yourself. There is a risk of an electric shock or causing a fire.
• Never use the charger as a mains power supply unit for electrical equipment.
1.2 Quinta MU Microphone Unit
Set up
• Always position the microphone units on a secure surface. If the microphone unit falls down, you can hurt yourself or others or damage
the microphone down.
• To align the gooseneck microphone on the microphone station and to avoid twisting it too far and causing premature wear,
please note that the gooseneck must be bent no further than an angle of 90° maximum.
Risk of injury
• If the microphone stations have a gooseneck microphone take care that you do not injure yourself on this e.g. poke it into your eye.
• The charging contacts of the microphone units can cause damage to property, injuries or fire damage if they come into contact with
conductive material such as jewellery, keys or chains. This closes the circuit and can thus cause the material to heat up. To avoid this sort of
unwanted circuit, the charging contacts must be handled with caution. This applies particularly if the microphone units are transported in
a bag or some other container together with metal objects.
Charging / rechargeable batteries
• When charging the microphone unit in the charger, take care to ensure that you do not injure yourself when putting the station in or
taking it out.
• Only switch on the charger when you have inserted all microphone units. Empty charging compartments should never be touched during
the charging process. You could receive an electric shock.
• Avoid letting the rechargeable batteries in the microphone unit become too deeply discharged. The rechargeable batteries could be
damaged and the life of them could be reduced.
• If battery operated equipment is not used for a lengthy period (e.g. 1 year) the self-discharge of the battery could be accelerated. The
temperature for long-term storage should be between +10° C and +30° C.
• If the microphone units are not used for several months, the rechargeable batteries in the microphone units should be charged up at least
twice a year in order to avoid them running out and deterioration in the performance due to self discharge.
Volume
•If the participants of a meeting use a headphone with the Quinta microphone stations, please make sure that the volume is
not set too high via the Quinta Conference software or the microphone unit itself. Otherwise, the hearing of the participants
could permanently be damaged.

Important:
• There must be an unobstructed path between the microphone units and the antennae, i.e. between the Quinta CU
control unit or the remote antennae and the microphone units there must not be any obstacles. With a free line of sight
between the control unit and the microphone units and the rod antennae the range is between 30 to 50 m [98.4 ft to 164 ft].
For optimum range the surface of the table is important, wood or plastic tables are ideal, but metal tables can cause interferences
and reduce the range.
• Please make sure that with a free line of sight the minimum distance between the antennae and the microphone units is not
less than 1 m [3.2 ft].
2.3 How to Connect the Antennae
2.3.1 Direct Connection
• Connect the antennae to the antenna connections . Please note that for diversity operation both antennae have to be connected!
A weighting circuit is used to make sure that the better antenna signal is received.
• For stand-alone operation we recommend using the supplied CA Q 11 angled rod antennae.
2.3.2 Remote Connection
• The Quinta CU control unit can also be operated with remote antennae. We recommed extremely low attenuation connecting cables which
are 10 m [32.8 ft] or 20 m [65.6 ft] long. Please note that the antennae have to be installed remotely.
2.2 Where to Place the Control Unit
• If you do not use remote antennae, place the Quinta CU control unit in the room where the meeting takes place. If you use remote
antennae, place the antennae in the conference room.
• Avoid shadowing effect of the antennae, especially by metallic surfaces.
• A free line of sight between the Quinta MU microphone units and the antennae of the Quinta CU control unit is essential for the operation of
the microphone units. Big obstacles in between can possibly affect the radio transmission. In such specific installations the use of remote
antennae can possibly achieve an improvement of the RF situation.
• If you want to install several Quint CU control units in a 19" rack, please make sure that there is a minimum distance of 1 U between the
control units to avoid interferences, especially if you do not use remote antennae.

Quinta – Control Unit 7
2.4 Audio Connection
• If required, connect the Audio Mix , XLR or Cinch 
master output of the Quinta CU control unit to the input of a
mixing console or amplifier.
• If you want to feed the audio signals into a network, connect
the AVB connection * to the network by using a CAT5 cable.
You can also connect other audio sources or devices with AVB
connection, which are defined as “Talker” (e.g. microphone) or
“Listener” (e.g. loudspeaker), as well as DSP devices for audio
data processing.
• You can connect e.g. external loudspeakers to the individual
channels of the audio output .
• Always route cables running to the unit where they will not be
pinched or cut by heavy or sharp objects.
*AVB is a uniform standard for Audio/Video networks for data
communication with which the most different components can
communicate with each other.
AVB is based on IEEE 802 Ethernet for the real-time streaming of
audio and video contents via Ethernet.
AVB features a bandwidth reservation, a low jitter master clock, low
latencies and a timing mechanism for the synchronisation. AVB
supplies a sufficient raw data bandwidth to transmit up to 200 audio
channels via one single Gigabit Ethernet port. Field tests showed
that a part of this can be used for extended functions. In order to
achieve this, an AVB network separates the AVB data traffic from the
Standard Ethernet data traffic and manages streams accordingly.
This means that an AVB network can be connected to a Standard
Ethernet network to transfer data to and from the network. The
performance of the streaming of media can only be guaranteed
within a group of AVB capable devices.
    
2.5 Power Supply
• Verify that the voltage rating of the unit matches that of the AC
mains outlet you are to use. If you connect the unit to the
wrong voltage, you may seriously damage it.
• Always route cables running to the unit where they will not be
pinched or cut by heavy or sharp objects.
• Connect the Quinta CU control unit to the mains . The
internal power supply unit of the control unit can automatically
adjust between 100 and 240 V at 50 - 60 Hz.

2.6 Connection of Media Control System and PC
• If you want to configure, control and monitor the system via
the Quinta Conference software, connect the USB connection
 or the LAN connection  or RS 232  (null modem cable
required) with a media control system or PC. The default IP
address of the Quinta CU control unit is: 192.168.1.55
• If the Quinta CU control unit is connected e.g. via a network
with a WLAN Access Point, you can access the web server of
the Quinta CU control unit e.g. with a smartphone.

Important:
Never access the Quinta CU control unit via the media
control system and the Quinta Conference software
simultaneously. In this case a correct function of the system
cannot be guaranteed.  

2.7 How to Switch the Control Unit On/Off
• Turn on the Quinta CU control unit with the On/Off switch .
The Power on LED will illuminate.
• The channel LED 1 to 4 will illuminate white to indicate the
availability. As soon as a microphone is activated, the channel
LED will illuminate red to indicate that the channel is occupied.
 
• At the factory the RF bands 2.4; 5.2 or 5.8 GHz* will be
activated (Automatic Mode). This means that the Quinta CU
control unit will select a free frequency and if necessary it will
select a different free frequency without any interferences. This
operating mode is recommended for normal use. The free
frequencies for the Quinta CU control unit can be deactivated
via the Quinta Conference software. The microphone unit will
automatically be adjusted to the frequency of the Quinta CU
control unit.
• If required you can select a fixed frequency (Manual Mode). Use
the tip of a pencil or a paper clip to press the countersunk push-
button for RF band selection . The push-button switches
through all available frequencies one after another and back to
the “Automatic Mode”. The manual frequency selection can
take up to 1.5 seconds and is immediately displayed. The
microphone units are automatically adjusted to the selected
frequeny band.
*Note:
The availability of the RF bands 2.4; 5.2 or 5.8 GHz depends on
the selected region.

2.8 Rack Mounting
• When mounting the Quinta CU control unit into a 19" rack housing leave 1 U for a ventilation panel above and below the control unit.
• Make sure that the mains connection, mains switch and all audio connections on the rear of the device are easily accessible.

3. Quinta MU Microphone Units
For the Quinta conference system there are three different microphone units available:
• Quinta MU 23 chairman microphone unit with three buttons (microphone, clear, function)
• Quinta MU 22 double delegate microphone unit with two microphone buttons
• Quinta MU 21 delegate microphone unit with one microphone button
The microphone units are provided with a locking XLR connection for removable gooseneck microphones of the Classis GM 31x Q series,
3-colour backlit buttons, braille above the buttons and an integrated wideband loudspeaker with equalization.
• Each microphone unit is programmed at the factory with an individual worldwide unique device ID so that the Quinta CU control unit can
control the microphone units.
• Each microphone unit is addressed with this individual device ID in the transmission protocol via radio transmission.
Important:
• The charging contacts of the microphone units can cause damages, injures or fire damages if they come into contact with
conductive materials such as jewellery, keys or chains. This can lead to a closed circuit and heat up the material.
• If the microphone units are to be operated by an external power supply, you can use the CA 2458 mains charger adapter.
•To align the gooseneck microphone of the Quinta MU microphone units and to avoid twisting it too far and causing
premature wear, the gooseneck must not be bent further than an angle of 90° at maximum.

Quinta – Charger 16
5. Quinta CD 2 Charger in the Quinta CC 2 | CC 2 / 600 Case
Quinta CC 2 is a modular charging and transport case. The basic version the Quinta CC 2 consists of a top cover (Quinta CT 2), a charger
(Quinta CD 2) for 10 microphone unit and a bottom with casters (Quinta CW 2). This version is suitable for microphone units using the
Classis GM 313 Q, GM 314 Q and GM 315 Q microphones.
For microphone units using the Classis GM 316 Q microphone the version Quinta CC 2 / 600 with a higher top cover (Quinta CT 2 / 600) will
be available.
• With the Quinta CD 2 charger integrated in the Quinta CC 2 or CC 2 / 600 case you can charge a maximum of 10 Quinta MU 23/22/21
microphone units with the Classis GM 313 Q, 314 Q, 315 Q or Classis GM 316 Q microphone. The charging state can be seen from the
outside through a glass panel.
• The Quinta CC 2 charging and transport case can be extended with another Quinta CD 2 charger for 10 microphone units. Because of a
possible instability more than two Quinta CD 2 chargers must not be piled up. Quinta CD 2 chargers that contain microphone units with
the Classis GM 316 Q microphone cannot be piled up because of the microphone length.
• For the Quinta CC 2 or CC 2 / 600 charging and transport case there is an optional compartment available for storing the Quinta CU
control unit and accessories such as cables and gooseneck microphones.
5.1 How to Use the Charger
• To achieve a 100% battery capacity of the rechargeable batteries, all microphone units should have 2 complete charging cycles (charging
and discharging) at least. Only after several charging and discharging cycles, the rechargeable batteries will achieve their full capacity.
• The Quinta MU microphone units are provided with high-performance nickel-metal hydrid (NiMH) batteries. These guarantee minimum
operating times of 20 hours. It takes about 2.5 hours to charge them.
• The service life of the batteries largely depends on the manner in which they are looked after and on how well the user recharges them. To
extend the service life of the batteries for as long as possible, the following charging cycle is recommended:
– Do not keep the microphone units in the charging case when it is switched on.
– Only put the microphone units in the charging case before a conference / application and fully charge them until the “fully charged”
status is shown.
– In particular, when the microphone units are inserted, the charging case should not be constantly switched on and off. For each
charging cycle, there is an initial 5-minute charge to check the battery status. If the case with the microphone units is switched on every
day (for example, because the mains is switched off automatically or by a cleaner), the microphone units will be slowly but constantly
overcharged and this will damage the batteries.
– The NiMH batteries used minimise the so-called “memory effect”, but their capacity is reduced when they are only partially discharged
on a regular basis. For this reason, the microphone units should be fully discharged every three months until they switch off auto-
matically. They can then be fully recharged. This procedure can, if necessary, be repeated a second time.
– If, despite this measure, the microphone unit does not operate for a sufficiently long period of time, the battery has reached the end
of its service life and must be replaced. The typical service life of the battery is greatly dependent on whether or not the above points
are observed. This is why batteries are not covered by warranties. If the above points are observed, a battery typically has a service life
of at least two years or 500 complete charging cycles, depending on which occurs first.
5.2 Charging Process
1. Connect the charger to AC power and switch it on. The switch will illuminate.
2. Put the switched-off microphone units into the charging compartments. If microphone units are switched on, they are switched off auto-
matically. When the microphone units are used again, they must be switched on by hand.
3. The charging process is indicated by the LED of the gooseneck and can be seen from the outside through a glass panel.

Note:
• If an error has occurred, try to restart the charging process. If the LEDs are still flashing rapidly, please contact your beyerdynamic
dealer.
• After some time the capacity of the rechargeable batteries is reduced technically. This will reduce the operating time.
• It is normal that the rechargeable batteries are heated up during the charging process.
• Clean the charging contacts with spirit or isopropyl alcohol from time to time. While cleaning avoid contact with the painted
surface.

7.1.2 Quinta and WLAN or WiFi
Like WLAN, the Quinta system uses the same bandwidth of approx. 22 MHz for each RF channel (Low, Mid, High). This results in three
compatible RF channels which are theoretically:
Compatible channel 1: 2400 MHz - 2428 MHz (theoretical mid frequency 2414 MHz)
Compatible channel 2: 2428 MHz - 2456 MHz (theoretical mid frequency 2442 MHz)
Compatible channel 3: 2456 MHz - 2484 MHz (theoretical mid frequency 2470 MHz)
Compatible channel 4: +5.2 GHz - +5.8 GHz
The Quinta system uses RF channels (Low, Mid, High) compatible to each other. For WLAN the user has to configure compatible RF channels.

7.1 Simultaneous Operation of the Quinta Conference System and other 2.4 GHz Devices (e.g. WLAN, Bluetooth)
7.1.1 Physical Laws
Due to many physical laws it is not possible to guarantee a simultaneous interference-free operation of different devices using the same
frequency band. Radio devices operating in the same frequency band will always disturb each other (the function can be disturbed as well).
For the use of UHF wireless microphones it is known that 2 devices can never be operated on the same frequency. It is only possible to operate
a certain number of compatible radio devices within a defined frequency band.
This applies also to the 2.4 GHz-ISM band (2400 MHz - 2484 MHz) or 5 GHz. Due to digital transmission techniques and various transmission
standards it is possible, but not recommended, to operate certain devices simultaneously within the same frequency band.

Quinta – Trouble Shooting 20
You can easily recognise that the individual WLAN channels overlap considerably due to their bandwidth. All neighbouring channels
(e.g. channel 1 & 2 or channel 7 & 8) cannot be used simultaneously, because they would disturb each other. Furthermore, channel 12 and 13
are not approved for the use in the USA. In general, these channels are not used either. Within the remaining frequency bands only the WLAN
channels 1, 6 and 11 can be used simultaneously.
For this reason the WLAN channels 1, 6 and 11 were selected for the RF channels Low, Mid and High used for the Quinta conference system.
Due to this frequency compatibility the Quinta system is operated WLAN-friendly.
Due to careful frequency planning it is possible to operate one Quinta CU control unit with more than 4,000 microphone units and a maximum
of two WLAN devices nearby simultaneously.
More tips for installation
• Keep a minimum distance of approx. 5 m between WLAN devices (e.g. Router, Repeater) and the transmitting and receiving antennae of
the Quinta CU control unit.
• The distance between laptops with activated WLAN interface does not influence the audio transmission of the microphone units as long as
there is no active data traffic.
• We recommend using different RF channels for WLAN or WiFi and Quinta channels. The distance between the WLAN and Quinta channels
should be as large as possible.
• The channels of the Quinta conference system can be selected with the supplied Quinta Conference Software.
7.1.3 Quinta and Bluetooth
• Bluetooth devices make use of the whole 2.4 GHz range with changing carrier frequencies (frequency hopping).
• Interferences caused by Bluetooth devices (including microwave ovens) in normal operation can be excluded due to different measures
inside the Quinta conference system and an advanced transmission protocol.
• It cannot be excluded, however, that an exisisting Bluetooth data traffic will be intefered by Quinta.
7.1.4 Example for Quinta, Media Control System and WLAN
The 2.4 GHz technology is used for many applications in discussions and meetings. In addition to a wireless discussion system other
functions (light or volume control etc.) are operated via a wireless 2.4 GHz touch screen of a media control system. Furthermore, the
participants of a meeting often have direct internet access via a WLAN access point.
The Quinta conference system and WLAN make use of compatible transmission standards. This should be considered when also using a media
control system with a touch screen. State-of the-art devices correspond to the WLAN standard.
1. Configure the Quinta conference system to the RF channel “Low”. The Quinta system then makes use of the frequency range of 2401 to
2423 MHz. This frequency range must be reserved for Quinta exclusively.
2. Configure the touch screen of the media control system to the frequency range of 2426 to 2448 MHz. This corresponds to the WLAN
channel 6. This frequency range must be reserved for the use of the touch screen exclusively.
3. Configure the WLAN access point to WLAN channel 11 making use of the frequency range 2451 to 2473 MHz. This frequency range must
be reserved for the use by WLAN exclusively.
4. As an alternative you can operate Quinta in the 5.2 or 5.8 GHz band.
