After you have completed the assembly of the wireless microphone several times, you will feel that assembly is a very simple matter. Will help you decide which type of system to choose according to your actual situation.
1. No matter what type of transmitter you are using, make sure to always use a new battery. The service life of the battery varies from system to system. Please refer to the user manual for the specific service life. The best way is-if your battery has been used for more than half of the service life recommended in the user manual, replace the battery.
2. Make sure the transmitter is turned off.
3. Turn on your receiver.
4. If your system has an automatic frequency selection function, press the "Select" button of the receiver. It will automatically search and locate a suitable frequency.
5. Temporarily lower the volume or level control of the receiver.
6. Turn on the transmitter.
7. If your system has the function of automatic transmitter installation, press the "Sync" button of the transmitter and it will lock on the frequency selected by the receiver. Check the receiver’s LED display or level meter to make sure it has received the signal from the transmitter. Then, adjust the receiver's volume control to the "normal" level.
8. Now adjust the audio gain of the transmitter. This is the key step to get the best sound and level!
You may need a screwdriver to make adjustments. Sing or speak loudly into the microphone, and slowly increase the gain until the receiver's "rf radio frequency level" or level meter occasionally flashes to show the pitch when the sound is loudest.
9. Walk around the performance venue and observe the receiver’s "power" display or RF level meter. It should be able to show sufficient signal reception in the covered area. If signal interruption occurs, the receiver or its antenna should be reconfigured to ensure that the signal can be received well. In short, setting the appropriate input gain is the most critical step in tuning a wireless microphone system. Setting it too low will cause too much noise; setting it too high will cause serious distortion and compression of the dynamic range. Adjusting the input gain of the transmitter is equivalent to setting the recording level of an analog recorder. The characteristics and control functions of the wireless transmitter are very important for accurately setting the gain. The distance between the transmitter and receiver of a wireless system has a great influence on the signal-to-noise ratio. The farther the transmitter is from the receiver, the worse the signal-to-noise ratio and the weaker the signal from the transmitter. As the system approaches the limit of the operating range, the frequency of signal interruptions is higher, and background noise (hissing) is more pronounced.
