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 Basic 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.
A total of 16 different channels are provided and can be selected using the dip switches fitted to each microphone. Below, a diagram of the switch configuration required to select each channel has been included. Never select the same channel for both microphones otherwise they may interfere with one another’s signal.
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.
The information included in this user manual is subject to change at any time and without notification:

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.
Connecting the Microphone System to an Audio Installation
On its own, this microphone system is not able to produce sound. As such, the receiver has been fitted with a
6.35 mm TS jack output socket so that it can be connected to an external audio system.
An external audio system usually includes an active speaker, mixer, or amplifier.
If in doubt, your local retailer will be able to offer advice regarding the cables 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 cable can be used to connect the WMD-24 Basic Duo. If the audio equipment is fitted with a 3-pin XLR microphone input, then a 6.35 mm jack to XLR cable or a jack to XLR adapter can be purchased separately and used to connect the WMD-24 Basic Duo to the audio installation.
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 by the body. The body is the part of the microphone extending from the battery compartment to the base of the microphone grille. Ideally, the microphone needs to be held as far away from the microphone grille as possible. 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 below the bottom 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 both 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 breaths 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 by the microphone, resulting in a feedback loop (often a loud, piercing noise)
Devine cannot be held responsible for any damage caused to any audio system due to the use of incorrect microphone technique.
Connecting the Microphone System to an Audio System
Start by 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 begin to raise the volume on your mixer to a standard level (maximum 0dB, or, if your system does not have a level indicator, bring it gradually to the halfway or three-quarter way point). By slowly increasing the volume, you will notice as soon as it is brought 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 problem or your system does not include these controls, raise the volume of the corresponding channel on the receiver.
If this is still unable to solve the problem, then another component of the signal chain needs to be 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 be the only devices using the 2.4 GHz frequency band. In theory, it is possible 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 nearby devices or equipment that operate using the same or similar frequency band, as well as the distance between 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 possible and that the selected channels of each system are as far apart as possible.
This wireless system can be operated using the following channels and corresponding frequencies:
Channel Frequency 1 Frequency 2 Channel 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 be downloaded and used to scan for WiFi signals. This will provide an overview of available WiFi networks, their signal strength, and useful information regarding the transmission frequency.
WiFi networks send a signal using the harmonised channels included below, with a 5 MHz interval between each (except channel 14).
WiFi channels that can have a strong influence over the performance of the WMD-24 channels have underlined below. 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 (but gradually weaken as the signal moves further away from the source).
Channel Frequency Channel Frequency
1 2412 MHz 8 2447 MHz
2 2417 MHz 9 2452 MHz
3 2422 MHz 10 2457 MHz

Using multiple systems at the same time without encountering any problems cannot be guaranteed. Since every situation and set-up is different, it is not possible to state with certainty that it would result in optimum performance.
Wireless Microphone Trouble Shooting
If you happen to encounter any problems while using your wireless microphone system, it’s recommended that this trouble shooting section is checked to see if a solution can be found. If none of the suggestions included below solve your particular problem, please contact your local retailer for further advice.
This trouble shooting section includes all of the most common possible issues and is not a complete list of every possible fault, defect, and their subsequent solution. This section is generally focussed on solving problems regarding the use of wireless microphones. As such, it may be that some of the included problems, causes, and solutions do not apply to your situation since product specifications can differ.
Problem Common Cause Solution
Receiver is not switching on Mains power socket not active Check that the mains power socket is
active, especially if it is (for example) a power block with a switch or a power switching system fitted with power sockets.
Power supply not securely connected
Check that the power supply is securely connected to the receiver and that the plug is securely connected to an active mains power supply socket.
Power button has not been pushed
Make sure that the power button of the receiver has been pressed.
Microphone is not switching onNo batteries Check that batteries have been installed in
the battery compartment.
Batteries incorrectly installed It might be that the batteries have been
installed the wrong way around. Always ensure that the batteries are installed so that the polarity (+/-) matches the polarity indicated in the compartment.
Batteries are empty Replace the batteries with new, high-quality
batteries.
No sound Volume is too low Turn the receiver volume control up a little
and check that the SIG indication LED lights up when the microphone is spoken into. If this is the case, then the device is receiving the signal as it should. If this does not solve the problem, then check the rest of the audio signal chain.
Mixer channel on mute or not properly set
Check the basic PA mixer controls like the mute switch, master volume level, trim or gain level, master volume, EQ control settings etc.
Microphone is not coupled with receiver
Make sure that the microphone is actively coupled with the receiver by following the instructions included in this manual.

Problem Common Cause Solution
Signal interference or signal drop
Receiver positioning is not optimum
Where possible, always ensure that the receiver is positioned so it can achieve the best possible ‘line of sight’ of the microphone transmitters.
Microphone is too far away from receiver
If the microphone is held more than 10 metres away from the receiver, this can cause a break in the signal since the signal from the microphone transmitter can no longer reach the receiver.
2.4 GHz error When the performance space is full of different devices operating on the same (or close to) 2.4 GHz frequency band, like laptops, smartphones, tablets and other wireless gadgets and equipment, this can cause wireless microphone system issues. Try switching to a different microphone signal or try to improve the ‘line of sight’ and reduce the distance between the receiver and microphone transmitter.
Distorted sound Sound settings are not optimal Check the volume level and other audio
system components that may be affecting the sound quality by overdriving the signal.
Incorrect microphone technique is being used
Check that the microphone technique of the performer is correct. If the sound is distorted or dull, then it is likely that the microphone grille is being covered by a hand.
