NOTICE!

Operating conditions

This device has been designed for indoor use only. To prevent damage, never expose the device to any liquid or moisture. Avoid

direct sunlight, heavy dirt, and strong vibrations. Only operate the device within the ambient conditions specied in the chapter

‘Technical specications’ of this user manual. Avoid heavy temperature uctuations and do not switch the device on immediately

after it was exposed to temperature uctuations (for example after transport at low outside temperatures). Dust and dirt inside can

damage the unit. When operated in harmful ambient conditions (dust, smoke, nicotine, fog, etc.), the unit should be maintained by

qualied service personnel at regular intervals to prevent overheating and other malfunction.

NOTICE!

External power supply

The device is powered by an external power supply. Before connecting the external power supply, ensure that the input voltage (AC

outlet) matches the voltage rating of the device and that the AC outlet is protected by a residual current circuit breaker. Failure to do

so could result in damage to the device and possibly the user. Unplug the external power supply before electrical storms occur and

when the device is unused for long periods of time to reduce the risk of electric shock or re.

NOTICE!

Risk of re due to incorrect polarity

Incorrectly inserted batteries may destroy the device or the batteries. Ensure that proper polarity is observed when inserting bat‐

teries.

NOTICE!

Possible damage by leaking batteries

Leaking batteries can cause permanent damage to the device. Take batteries out of the device if it is not going to be used for a

longer period.

4 Installation and starting up

4.1 General Information

Unpack and check carefully there is no transportation damage before using the unit. Keep the

equipment packaging. To fully protect the product against vibration, dust and moisture during

transportation or storage use the original packaging or your own packaging material suitable

for transport or storage, respectively.

Create all connections while the device is o. Use the shortest possible high-quality cables for

all connections. Take care when running the cables to prevent tripping hazards.

nThis device utilizes frequencies that are not harmonized within the European Union (EU)

and therefore may only be used in certain EU member states. In all European countries, the

frequencies used for the transmission of audio signals are strictly regulated. Before you

start, make sure the frequencies are allowed in the respective country and check whether

the operation must be reported to the appropriate authority.

For more information, please visit: http://www.thomann.de.

nMake sure that transmitter and receiver are both tuned to the same channel.

nNever set multiple transmitters to the same channel.

nMake sure that there are no metal objects between the transmitter and receiver.

nAvoid interference from other radio or in-ear systems.

4.2 Receiver

The unit has been designed for rack mounting in a standard 19" rack; it occupies one rack unit

(RU).

NOTICE!

External power supply

The device is powered by an external power supply. Before connecting the

external power supply, ensure that the input voltage (AC outlet) matches the

voltage rating of the device and that the AC outlet is protected by a residual cur‐

rent circuit breaker. Failure to do so could result in damage to the device and pos‐

sibly the user.

Unplug the external power supply before electrical storms occur and when the

device is unused for long periods of time to reduce the risk of electric shock or

re.

First, connect the power adapter to the receiver and then plug the power adapter into the

power outlet.

Installation and starting up

UHF Wireless System

Attach the included antennas to the rear panel of the transmitter. To improve the transmission

quality and to adapt to the spatial conditions they are rotatable and swivelling.

In case the space provided on the device for direct assembly of the antennas is not sucient,

for example because the space on the rack is narrow, you can use the optionally available

coaxial cable to assemble the antennas separately from the device.

Connect the audio outputs of the receiver to your mixer or your amplier. Ensure that only one

of the two outputs of the receiver (XLR or jack) is ever used at a time for the overall channel,

because faults might occur otherwise.

4.3 Handheld microphone (Quad H)

Unscrew the bottom housing section of the handheld microphone. Insert the batteries. Pay

attention to the correct location of the poles. The correct battery arrangement is illustrated in

the battery compartment. Close the battery compartment, screw the bottom housing section

back on, and switch the transmitter on.

4.4 Bodypack transmitter (Quad B)

Press the button on the rear side of the bodypack transmitter and pull the battery compart‐

ment cover downwards. Insert the batteries. Pay attention to the correct location of the poles.

Close the battery compartment and switch the transmitter on.
