DANGER!
Danger for children
Ensure that plastic bags, packaging, etc. are disposed of properly and are not
within reach of babies and young children. Choking hazard!
Ensure that children do not detach any small parts (e.g. knobs or the like) from
the unit. They could swallow the pieces and choke!
Never let children unattended use electrical devices.
NOTICE!

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
fire.
NOTICE!
Risk of fire due to incorrect polarity
Incorrectly inserted batteries may destroy the device or the batteries.
Ensure that proper polarity is observed when inserting batteries.

n 9.5" diversity receiver
– Two antennas for optimum reception quality
– Automatic frequency scanning
– Infrared interface for the transfer of the frequency selection from the receiver to the
transmitter
– Very high sensitivity at very high Signal-to-Noise Ratio
– Adjustable Squelch
– Outputs: XLR, 1/4" phone socket
– Mounting brackets for mounting in a 19" rack
– Operating voltage supply: DC 12 V , a suitable power supply is included
n Transmitter: battery powered handheld cardioid microphone

General information
Unpack and carefully check that there is no transportation damage before using the unit. Keep
the equipment packaging. To fully protect the device against vibration, dust and moisture
during transportation or storage use the original packaging or your own packaging material
suitable for transport or storage, respectively.
Establish all connections as long as the unit is switched off. Use the shortest possible highquality cables for all connections.

n This 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.
n Make sure that transmitter and receiver are both tuned to the same channel.
n Never set multiple transmitters to the same channel.
n Make sure that there are no metal objects between the transmitter and receiver.
n Avoid interference from other radio or in-ear systems.

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

Attach the supplied antennas to the rear panel of the receiver. To improve transmission quality
and to adapt to the spatial conditions the antennas are rotatable and swivelling.
If the space for the direct mounting of the antennas on the unit is not sufficient, for example,
because of restricted space in the rack, you can use the optional coaxial cable to mount the
antennas separated from the unit. For larger configurations with up to four receivers, the
usage of the optional antenna distributor is appropriate.
Connect one of the audio outputs of the receiver to your mixing console or amplifier. Make
sure that only one of both output is used at a time. Otherwise, malfunction may occur.

Transmitter
Unscrew the lower housing part of the handheld microphone. Insert the batteries respecting

Troubleshooting
In the following we list a few common problems that may occur during operation. We give you
some suggestions for easy troubleshooting:
Troubleshooting
free solo HT
39
Page 40
Symptom Remedy
No sound 1. Check the power supply of the transmitter and receiver.
2. Make sure that both transmitter and receiver operate in the same frequency
range. The frequency range is stated on the devices.
3. Are both transmitter and receiver set to the same channel?
4. Check the connection between the receiver and the connected audio device
(amp, mixer). Is the connected audio device switched on and does the signal
level on the output of the receiver match the input sensitivity of the audio
device?
5. Try to improve the transmission by moving the transmitter closer to the
receiver.
6. Make sure that no metal objects near the transmitter or receiver obstruct the
transmission.
Transmission is disturbed 1. Modify the orientation of the antennas.
2. If you use more than one wireless system at the same time, check the used
frequencies and channels.
3. Interference can also be caused by other radio or in-ear systems.
