5.2 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

(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 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. 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 automatically. 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.

Note:

• If an error has occurred, try to restart the charging

process. If the LEDs are still flashing rapidly, please

contact your beyerdynamic dealer.

• For a reliable charging of the rechargeable batteries and

in order to avoid long-term damages the ambient

temperature must not exceed +35 °C [95 °F] during

charging.

5. Quinta CD 2 Charger in the

Quinta CC 2 | CC 2 / 600 Case and

Quinta CD 3 in the Quinta CC 3 Case

Quinta CC 2 is a modular charging and transport case for the Quinta

MU 23/22/21 microphone units. 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)

will be 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

consists of 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

23/22/21 microphone units with the Classis GM 313 Q, 314 Q,

315 Q or Classis GM 316 Q microphone. With the Quinta CD 3

charger integrated in 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 the outside 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

microphone units. 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 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 automatically. 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.

LED indicator when the batteries are recharged:

a) Gooseneck LED or LED strips

are flashing red. . . . . . . . . . . . . . . Battery is charged

b) Gooseneck LED or LED strips

illuminates red permanently. . . . . . Battery is completely full

c) Gooseneck LED or LED strips

are flashing red rapidly . . . . . . . . . Error

• 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.
