6. Channel Selector:
Use this rotary switch to choose one of the 16 available channels. Note that the se-
lected channel on the receiver should always be identical to that of the transmitter.
7. Gain control:
first set the desired input level to mic or line (4).
After this you can further fine-tune the input sensitivity to avoid
signal overload (distortion).
8. Lavalier Microphone:
unidirectional condenser type, this dis-
cretely worn mic can be used to amplify all kinds of sounds.
(ex. enhance the voice of a teacher or speaker). This lavalier
microphone can be replaced by our
“HM-36U headset micro-
phone”
(order code: 427), often used for aerobics etc.
9. Tie Clip:
used to clip the lavalier on the tie or lapel of a person.
10. Battery Compartment:
Insert two AA rechargeable or dry (Al-
kaline) batteries into the compartment. Make sure that the po-
larity of batteries is correct.
11. Battery Cover:
unscrew it gently and slide it down to open the battery compartment or have access to
the channel selector (5)
.
12. Charger Input:
connect the supplied charger cable between the receiver and the microphone. It takes
around 10 hours to recharge the batteries. While charging, the “low battery” indicator is flashing.
Important note:
be sure to insert rechargeable batteries (preferable “Ni-MH” type) in the transmitter be-
fore you connect the charger!
NEVER
charge normal batteries like for example “Alkaline” type) !!!
INSTALLATION GUIDELINES:
Install the receiver in a ventilated location where it will not be exposed to high temperatures or humidity.
Placing and using the unit for long periods near heat-generating sources such as amplifiers, spotlights, etc.
will affect its performance and may even damage the unit.
The unit can be mounted in 19-inch racks: for this purpose a special 19” adapter (RP-WMIC) is available,
see below.
When installed in a booth or flight case, please make sure to minimize shocks and vibrations during trans-
port.
To avoid condensation to be formed inside, allow the unit to adapt to the surrounding temperatures when
bringing it into a warm room after transport. Condense sometimes prevents the unit from working at full
performance.
Also check the extra notes in the chapter “SETUP and CONNECTIONS”
INSTALLING THE RECEIVER:
Standalone:
You can use the receiv-
er standalone: just put both antennas
in vertical position and connect the
receiver as described in the chapter
“connections”.
In a 19” rack:
you can install one or
two receivers in a 19” rack, using an
optional “RP-WMIC” adapter:
1.
Install 2 pieces ear short racks on
both side sides of receiver.
2.
Install the receiver inside the 19”
metal rack adapter by screwing
the ear short racks.
SETUP AND CONNECTIONS
! Some important notes before we start !
One receiver can only be used with one transmitter (handheld mic / belt pack). Using 2 or more transmit-
ters simultaneously with the same receiver is impossible: this will result in a lot of interference and trouble!
Receiver and transmitter should always use the same channel setting (frequency)!
The distance between receiver and transmitter should at least be 1 meter.
To minimize interferences install the receiver away from big metal surfaces/objects, TV and other wireless
appliances.

Try to minimize the number of obstructions (thick concrete walls, big metal objects, …) in the path between
the transmitter and receiver.
Up to 3 or 4 transmitters can be used simultaneously on condition that each has its own receiver!
RECEIVER – AUDIO CONNECTIONS
First determine which audio inputs are available on your mixer, next decide how to connect the receiver:
To a balanced MIC-input of the audio mixer:
close
the gain of the mixer input and set the mic/line switch
on the receiver (7) to MIC. Use an XLR/XLR cable to
connect the receiver “XLR-output (5)”. Switch the
transmitter (hand mic/belt pack) on and bring the in-
put gain of the mixer slowly up.
To a balanced LINE-input of the audio mixer:
close the gain of the mixer input and set the mic/line
switch on the receiver (7) to LINE. Use an XLR/XLR
cable to connect the receiver “XLR-output (5)”.
Switch the transmitter (hand mic/belt pack) on and
bring the input gain of the mixer slowly up.
To an unbalanced MIC-input of the audio mixer:
close the gain of the mixer input and set the mic/line
switch on the receiver (7) to MIC. Use the supplied
JACK/JACK cable to connect the receiver “JACK-
output (6)”. Switch the transmitter (hand mic/belt
pack) on and bring the input gain of the mixer slowly
up.
To an unbalanced LINE-input of the audio mixer
or hifi stereo set:
close the gain of the mixer input and set the mic/line switch on the receiver (7) to LINE.
Use the supplied JACK/JACK cable to connect the receiver “JACK-output (6)”. Switch the transmitter
(hand mic/belt pack) on and bring the input gain of the mixer slowly up.
NOTE:
never use the balanced and unbalanced outputs together, this will results in signal loss and in-
creased noise.
WIRELESS HAND MIC – SETUP
Switch the Receiver on and select a channel.
Open the battery compartment and insert two AA batteries (alkaline or fully charged Ni-MH type).
Select exactly the same frequency channel (5) as on the receiver.
Press the power switch (3) for some seconds: one of the diversity LEDs (4) on the receiver should be lit to
indicate that the RF-signal of the transmitter is captured.
Speak through the mic: the AF indicator (3) will flash to the rhythm of your voice.
While checking the system, walk around to check if you encounter any dead spots (no reception): in these
cases, try to change the position of the receiver.
BELT PACK – SETUP
Switch the Receiver on and select a channel.
Open the battery compartment and insert two AA batteries (alkaline or fully charged Ni-MH type).
Select exactly the same frequency channel (6) as on the receiver.
Connect the lavalier microphone or optional headset mic and put the MIC/LINE switch (4) on the belt pack
to MIC.
Alternatively you can also connect a line audio signal (ex. Guitar), in that case you should put the
MIC/LINE switch (4) on the belt pack to LINE.
Press the power switch (2) for some seconds: one of the diversity LEDs (4) on the receiver should be lit to
indicate that the RF-signal of the transmitter is captured.
Speak through the mic: the AF indicator (3) will flash to the rhythm of your voice.
If needed, you can still fine-tune the audio level with the gain knob (7).
While checking the system, walk around to check if you encounter any dead spots (no reception): in these
cases, try to change the position of the receiver.
