In the environment without professional radio equipment, the use of multimedia conference sound is not suitable for adjusting the handheld wireless microphone, but adjusting the wireless microphone receiver. The adjustment steps can be as follows:
Open the cover of the old wireless microphone and use it on the old wireless microphone.
Turn on the power supply of the handheld wireless microphone and wireless microphone receiver, place the handheld wireless microphone in front of your chest, turn your back to the wireless microphone receiver, shout and walk away, find a blind sound position, and set this position as the blind sound reference point.
Power off, find the antenna access point on the circuit board of the wireless microphone receiver, find the first adjustable capacitor, or adjustable resistance, or inductance along the antenna input circuit, make a mark in place, and fine tune a little counterclockwise or clockwise.
Turn on the mobile phone, put the handheld wireless microphone on your chest, turn your back to the wireless microphone receiver, and walk to the blind reference point while shouting. If the blind area disappears, the adjustment is successful. If you fine tune it counterclockwise, you can change it to fine tune it clockwise, and it will succeed once or twice.
If you use it well in one site and change to another site, sometimes there will be breakpoints or frequency shifts. During debugging or rehearsal, if there is a problem with the microphone, it will generally fine tune the frequency.
Add a few points. An enamelled wire can be welded to the negative pole of the microphone battery base. Some people do not use rechargeable batteries, and the uncharged batteries can also avoid the decrease of frequency (because the current of rechargeable batteries is low).
In the place where the frequency drops, the receiver can be placed close to the actor, which does not affect the beauty and cannot be touched.
If you use a rechargeable battery, you must replace the fully charged rechargeable battery every 15 minutes. It is also possible to change the receiver in different directions, and some can avoid frequency loss.
