Using this System
This wireless microphone system offers a huge number of options and features. It is therefore strongly
recommended that the tips and advice included below is read in detail so that you can get the best out of this
microphone system while using it safely.
Legal Use of the 2.4 GHz Band
This microphone system operates using the 2.4 GHz wireless band. This is the same band used by WiFi
networks, Bluetooth, and other comparable signals.
This frequency band can be used freely worldwide, and as such, this microphone system can also be used
freely worldwide.
Ensure Optimal Transmitter and Receiver Signal Strength
The biggest disadvantage of using the 2.4 GHz frequency band is that many locations may already be busy
with wireless signal traffic like WiFi networks, Bluetooth signals, and similar signals that operate within or
near the same frequency range. It may also be the case that audience members may have smartphones or
similar gadgets that are constantly scanning for an available signal.
In the worst case, this can cause serious problems with the performance of the WMD-24 PRO Duo
microphone system.
To prevent or overcome these possible problems, the following measures can be taken:
– Make sure that any other transmitting or receiving device or equipment that operates using the frequency
band is moved at least 1 metre away from the system.
– As much as possible, try to maintain a clear ‘line of sight’ between the transmitter and receiver and that
nothing is blocking the signal transmission. Obstructions can include walls, furniture, or audience members.
The less the signal is blocked, the more stable the signal becomes.
– A good tip is to place the receiver in a relatively high position. This will increase the ‘line of sight’ of the
receiver so that it can better detect the signal from the transmitter (handheld microphone).
Switching the Receiver On
Before switching the receiver on, ensure that it is placed in an optimum position (as described above) on a
stable surface. Then, connect the DC power supply to the power input of the receiver and plug the power
supply into a compatible mains power socket. Use the Power button of the receiver to switch it on and off.
Channel Selection
Since the 2.4 GHz frequency band can be busy, the WMD-24 Basic Duo comes fitted with a practical
function that makes it possible to set a separate channel for both microphones to avoid any possible
interference.
One of16 different channels can be selected using the navigation buttons on the front panel of the receiver.
The display will show the selected channel number as well as the exact 2.4 GHz transmission frequency.
IR Synchronisation
Once the receiver has been positioned and switched on and a receiver channel has been selected per
microphone, it is necessary to couple the correct microphone to the corresponding selected channel.
Note: Always make sure that high-quality batteries have been installed in the microphones.
Briefly press the power button of one of the microphones twice. This will produce an audible beep indicating
that the microphone is now in synchronisation mode.
Then, press the ‘ID’ button of the corresponding microphone channel of the receiver (make sure this is the
channel you need to couple the specific microphone with). Once the beep has stopped and the LED indicator
is no longer blinking, the synchronisation is successfully completed. Now, repeat the same process with the
second microphone.
The synchronisation between the receiver and microphone is now saved. There is no need to repeat the
synchronisation process every time before using the system.
