Using this System
This wireless microphone system offers a huge num er of options and features. It is therefore strongly
recommended that the tips and advice included elow is read in detail so that you can get the est out of this
microphone system while using it safely.
Legal Use of the 2.4 GHz and
This microphone system operates using the 2.4 GHz wireless and. This is the same and used y WiFi
networks, Bluetooth, and other compara le signals.
This frequency and can e used freely worldwide, and as such, this microphone system can also e used
freely worldwide.
Ensure Optimal Transmitter and Receiver Signal Strength
The iggest disadvantage of using the 2.4 GHz frequency and is that many locations may already e usy
with wireless signal traffic like WiFi networks, Bluetooth signals, and similar signals that operate within or
near the same frequency range. It may also e the case that audience mem ers may have smartphones or
similar gadgets that are constantly scanning for an availa le signal.
In the worst case, this can cause serious pro lems with the performance of the WMD-24 PRO Duo
microphone system.
To prevent or overcome these possi le pro lems, the following measures can e taken:
– Make sure that any other transmitting or receiving device or equipment that operates using the frequency
and is moved at least 1 metre away from the system.
– As much as possi le, try to maintain a clear ‘line of sight’ etween the transmitter and receiver and that
nothing is locking the signal transmission. O structions can include walls, furniture, or audience mem ers.
The less the signal is locked, the more sta le the signal ecomes.
– 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 etter 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 descri ed a ove) on a
sta le surface. Then, connect the DC power supply to the power input of the receiver and plug the power
supply into a compati le mains power socket. Use the Power utton of the receiver to switch it on and off.
Channel Selection
Since the 2.4 GHz frequency and can e usy, the WMD-24 Basic Duo comes fitted with a practical
function that makes it possi le to set a separate channel for oth microphones to avoid any possi le
interference.
One of16 different channels can e selected using the navigation uttons on the front panel of the receiver.
The display will show the selected channel num er as well as the exact 2.4 GHz transmission frequency.
IR Synchronisation
Once the receiver has een positioned and switched on and a receiver channel has een selected per
microphone, it is necessary to couple the correct microphone to the corresponding selected channel.
Note: Always make sure that high-quality atteries have een installed in the microphones.
Briefly press the power utton of one of the microphones twice. This will produce an audi le eep indicating
that the microphone is now in synchronisation mode.
Then, press the ‘ID’ utton of the corresponding microphone channel of the receiver (make sure this is the
channel you need to couple the specific microphone with). Once the eep has stopped and the LED indicator
is no longer linking, the synchronisation is successfully completed. Now, repeat the same process with the
second microphone.
The synchronisation etween the receiver and microphone is now saved. There is no need to repeat the
synchronisation process every time efore using the system.

Connecting the Microphone System to an Audio Installation
On its own, this microphone system is not a le to produce sound. As such, the receiver has een fitted with a
6.35 mm TS jack output socket so that it can e connected to an external audio system.
An external audio system usually includes an active speaker, mixer, or amplifier.
If in dou t, your local retailer will e a le to offer advice regarding the ca les you need to use. However,
most audio systems come fitted with a standard 6.35 mm TS jack input, in which case, the included jack
ca le can e used to connect the WMD-24 PRO Duo. If the system is fitted with a 3-pin XLR microphone
input, then a 6.35 mm jack to XLR ca le or a jack to XLR adapter can e purchased separately and used to
connect the WMD-24 PRO Duo to the audio installation.
The WMD-24 Pro DUO also provides two independent 3-pin XLR outputs that can e used to send the
separate signals of oth microphones. This offers a huge advantage, since the sound of oth microphones
can e individually fine-tuned and different effects (like echo) can e added to each microphone signal using
your mixer.
Display
The receiver screen displays a lot of practical information,
some of which can also e read on the microphone display
screens.
RF: wireless signal strength
AF: audio signal strength
Channel indicator
Channel A and B use indicator. Also indicates wireless synchronisation mode
Exact microphone frequency (this depends on the selected channel. A and B cannot e set to the
same channel)
Microphone Technique
A microphone is not a complicated device. Anyone can speak into a microphone and the device will ensure
that the sound is sent to any connected external audio equipment. But, to ensure optimum sound quality and
prevent causing damage to any external audio equipment, using the correct microphone technique is
essential.
Make sure that the microphone is held securely y the ody. The ody is the part of the microphone
extending from the attery compartment to the ase of the microphone grille. Ideally, the microphone needs
to e held as far away from the microphone grille as possi le. Do not tap the microphone grille to check that
the microphone is working.
Hold the microphone in front of and close to the mouth, at the height of the chin and just elow the ottom
lip. Make sure that the microphone does not actually touch the lip and try to maintain a distance of around a
finger’s width.
Speak clearly into the microphone at a normal volume.
The following points can have a negative effect on oth the sound quality and speech clarity:
– Holding the microphone too low (the ventriloquist effect)
– Holding the microphone to close to the mouth so that harsh sounds and reaths are amplified
– Speaking to loudly or too quietly into the microphone
– Holding the microphone near a speaker. The sound coming from the speaker is re-amplified y the
microphone, resulting in a feed ack loop (often a loud, piercing noise)

Devine cannot e held responsi le for any damage caused to any audio system due to the use of incorrect
microphone technique.
Setting Up Your Audio Installation
Start y setting the volume faders or controls of your mixer to zero. This includes any ‘gain’ or ‘trim’ controls.
After connecting the receiver to your mixer, speak into the microphone using the correct microphone
technique, and then gradually egin to raise the volume on your mixer to a standard level (maximum 0dB, or,
if your system does not have a level indicator, ring it gradually to the halfway or three-quarter way point). By
slowly increasing the volume, you will notice as soon as it is rought to an appropriate level and start to fine-
tune the whole system.
If the signal strength is not sufficient, use the ‘trim or ‘gain’ controls to raise the signal strength to an
appropriate level. If this does not solve the pro lem or your system does not include these controls, raise the
volume of the corresponding channel on the receiver.
If this is still una le to solve the pro lem, then another component of the signal chain needs to e adjusted
like the master volume of the mixer.
Using More Than One System at the Same
If you intend to operate multiple WMD-24 systems at the same time, it is important to note that the systems
are unlikely to e the only devices using the 2.4 GHz frequency and. In theory, it is possi le to link
approximately two to three systems together (for a 4 to 6 microphone set-up) and operate them at the same
time.
However, please note that any near y devices or equipment that operate using the same or similar
frequency and, as well as the distance etween the different transmitters, can dramatically affect the result.
If you do decide to operate more than one system at the same time, then make sure that any equipment or
devices likely to cause signal interference are placed as far away as possi le and that the selected channels
of each system are as far apart as possi le.
This wireless system can e operated using the following channels and corresponding frequencies:
Channel Frequency 1 Frequency 2 Channal Frequency 1 Frequency 2
1 2406 MHz 2446 MHz 9 2422 MHz 2462 MHz
2 2408 MHz 2448 MHz 10 2424 MHz 2464 MHz
3 2410 MHz 2450 MHz 11 2426 MHz 2466 MHz
4 2412 MHz 2452 MHz 12 2428 MHz 2468 MHz
5 2414 MHz 2454 MHz 13 2430 MHz 2470 MHz
6 2416 MHz 2456 MHz 14 2432 MHz 2472 MHz
7 2418 MHz 2458 MHz 15 2434 MHz 2474 MHz
8 2420 MHz 2460 MHz 16 2404 MHz 2444 MHz
A third-party smartphone app can e downloaded and used to scan for WiFi signals. This will provide an
overview of availa le WiFi networks, their signal strength, and useful information regarding the transmission
frequency.
WiFi networks send a signal using the harmonised channels included elow, with a 5 MHz interval etween
each (except channel 14).
WiFi channels that can have a strong influence over the performance of the WMD-24 channels have
underlined elow. However, this does not mean that other strong WiFi signals will not affect the performance
of the WMD-24. The included frequencies are measured at their peaks, which are also present within
adjacent frequencies ( ut gradually weaken as the signal moves further away from the source).
