If the microphone unit falls down, you can hurt yourself or others or damagethe microphone unit.• To align the gooseneck microphone on the microphone unit 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 ofunwanted circuit, the charging contacts must be handled with caution. This applies particularly if the microphone units are transported ina 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 duringthe 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 leasttwice 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 isnot set too high via the Quinta Conference software or the microphone unit itself. Otherwise, the hearing of the participantscould permanently be damaged.1.3 Disposal• Old batteries may contain substances that are harmful to your health and environment. • The device provides built-in rechargeable batteries, which you cannot remove yourself, therefore, return the device to your dealer for recycling when the batteries are exhausted. • All batteries are recycled to reclaim valuable material such as iron, zinc or nickel.• This symbol on the product, in the instructions or on the packaging means that your electrical and electronic equipment should be disposed at the end of its life separately from your household waste.

2. Quinta CU Control UnitThe Quinta CU control unit is the heart of the system. It controls the delegate and chairman microphone units. With one control unit a maxi-mum of 4 speakers (e.g. 3 delegates and 1 chairman) can speak simultaneously. The radio transmission is in the triple band (2.4 / 5.2 / 5.8 GHzfrequency band).The control unit has been designed for installations on tables or 19" rack mounting. When setting up the system, please follow the safety instructions mentioned in chapter 1. Furthermore, please note• the ambient temperature of the installation site must not exceed 40 °C [104 °F]. • there must not be exceeding dust and humidity a the installation site.• that the unit is not exposed to direct sunlight.• the connection must be protected against direct access during operation.• that there must be a strain relief of the cables.• the installation site must be protected against vibrations.2.1 Controls and IndicatorsPower on LEDAudio channel LEDs 1 to 4 (white = channel vacant; red = channel occupied)Display to indicate operating mode, channel, headphone volumeStandby button to turn off all microphone units centrallyPush-button for frequency band selection Volume control for headphone / channelHeadphone connectionUSB connectionAntenna connectionsAVB (Audio Video Bridging) network connection for digital audio signals via CAT5 cables, RJ45Audio input (Audio IN) for the connection of external sound sources, 3-pin Phoenix terminal strip, balancedAudio output, individual channels, 4 x 3-pin Phoenix terminal strips, balancedAudio output Mix (Master), 3-pin Phoenix terminal strips, balancedAudio output Mix (Master), 3-pin XLR, balanced Audio output Mix (Master), RCA, unbalanced LAN connection for PC / network, RJ 45Connection for media control system / PC / network, RS 232On/Off switchFuseMains connectionQuinta – Control Unit 5FrontRear                  
Quinta – Control Unit 6            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 sightbetween 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 interferencesand reduce the range. • Please make sure that with a free line of sight the minimum distance between the antennae and the microphone units is notless than 1 m [3.2 ft]. 2.3 How to Connect the Antennae2.3.1 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 whichare 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 remoteantennae, 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 ofthe microphone units. Big obstacles in between can possibly affect the radio transmission. In such specific installations the use of remoteantennae 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 thecontrol units to avoid interferences, especially if you do not use remote antennae.
Quinta – Control Unit 72.4 Audio Connection• If required, connect the Audio Mix , XLR or Cinch master output of the Quinta CU control unit to the input of amixing console or amplifier.• If you want to feed the audio signals into a network, connectthe AVB connection * to the network by using a CAT5 cable.You can also connect other audio sources or devices with AVBconnection, which are defined as “Talker” (e.g. microphone) or“Listener” (e.g. loudspeaker), as well as DSP devices for audiodata processing. • You can connect e.g. external loudspeakers to the individualchannels of the audio output .• Always route cables running to the unit where they will not bepinched 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 cancommunicate with each other. AVB is based on IEEE 802 Ethernet for the real-time streaming ofaudio and video contents via Ethernet. AVB features a bandwidth reservation, a low jitter master clock, lowlatencies and a timing mechanism for the synchronisation. AVB supplies a sufficient raw data bandwidth to transmit up to 200 audiochannels via one single Gigabit Ethernet port. Field tests showedthat a part of this can be used for extended functions. In order toachieve this, an AVB network separates the AVB data traffic from theStandard Ethernet data traffic and manages streams accordingly.This means that an AVB network can be connected to a StandardEthernet network to transfer data to and from the network. Theperformance 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 ACmains outlet you are to use. If you connect the unit to thewrong voltage, you may seriously damage it. • Always route cables running to the unit where they will not bepinched 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 automaticallyadjust 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 viathe 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 networkwith a WLAN Access Point, you can access the web server ofthe 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 systemcannot be guaranteed.  
Quinta – Control Unit 8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 channelLED 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 CUcontrol unit will select a free frequency and if necessary it will select a different free frequency without any interferences. Thisoperating mode is recommended for normal use. The free frequencies for the Quinta CU control unit can be deactivatedvia the Quinta Conference software. The microphone unit willautomatically be adjusted to the frequency of the Quinta CUcontrol unit. • If required you can select a fixed frequency (Manual Mode).

The basic version the Quinta CC 2 consists of a top cover (Quinta CT 2), a charger (Quinta CD 2) for 10 Quinta MU 23/22/21 microphone unit and a bottom with casters (Quinta CW 2). This version is suitable for Quinta MU 23/22/21 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) willbe available.Quinta CC 3 is a modular charging and transport case for the Quinta MU 33/31 microphone units. The basic version the Quinta CC3 consistsof a top cover (Quinta CT 2), a charger (Quinta CD 3) for 12 Quinta MU 33/31 microphone unit and a bottom with casters (Quinta CW 2). • 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 23/22/21microphone units with the Classis GM 313 Q, 314 Q, 315 Q or Classis GM 316 Q microphone. With the Quinta CD 3 charger integratedin the Quinta CC 3 case you can charge a maximum of 12 Quinta MU 33/31 microphone units. The charging state can be seen from theoutside through a glass panel.• The Quinta CC 2 or CC 3 charging and transport case can be extended with another Quinta CD 2 or CD 3 charger for 10 or 12 microphoneunits. Because of a possible instability more than two Quinta CD 2 or CD 3 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 or CC 3 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 Charging Process1. 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.

Error5.2 Notes for Microphone Units and Rechargeable Batteries• To achieve a 100% battery capacity of the rechargeable batteries, all microphone units should have 2 complete charging cycles (chargingand 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 operating times of approx. 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. Toextend 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 constantlyovercharged 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 dischargedon 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 endof 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 lifeof at least two years or 500 complete charging cycles, depending on which occurs first.Note:• If an error has occurred, try to restart the charging process. If the LEDs are still flashing rapidly, please contact your beyerdynamicdealer.• 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.

Refer also tochapter 7.1.
Quinta – Trouble Shooting 207.1.2 Quinta and WLAN or WiFiLike 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.Frequencies Quinta / WLAN for example for 2.4 GHzQuinta WLANChannel . . Centre frequency Channel . . . . . . . . . . . . . . . . . .

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 operatea 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 21You 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 13are not approved for the use in the USA. In general, these channels are not used either. Within the remaining frequency bands only the WLANchannels 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.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 ofthe Quinta CU control unit. • The distance between laptops with activated WLAN interface does not influence the audio transmission of the microphone units as long asthere 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 channelsshould 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 WLANThe 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 mediacontrol 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 to2423 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 mustbe reserved for the use by WLAN exclusively.4. As an alternative you can operate Quinta in the 5.2 or 5.8 GHz band.
