When & How to Use Wireless Lavalier Microphones
Wireless Microphone, Microphone Usage Precautions We all know? Talk to everyone today Wireless microphone, Microphone Notes, I hope we can provide some help, let alone know that we come to understand.
1, impedance matching
The best match between the output impedance of the wireless microphone and the input impedance of the amplifier when using a wireless microphone is the best match, with a mismatch ratio of more than 3: 1 that can affect the transmission. For example, 50Ωwireless microphone connected to the input impedance of 150Ω amplifier, although the output can increase nearly 7Db, but the high and low frequency sound will be a significant loss.
2, the angle between the sound source and wireless microphone
Each wireless microphone has its effective angle, the general sound source should be aligned wireless microphone centerline, the larger the declination between the two, the greater the loss of treble. Sometimes when using a wireless microphone, with the sound of ,then deflect it some angle, you can reduce some.

3, Wireless microphone location and height
When amplifying, wireless microphone do not place or aim the speaker close to the speaker first, otherwise it will cause howling.
The height of the wireless microphone should be determined by the height of the sound source. If a person speaks or a few people sing, the height of the wireless microphone should be consistent with that of the singer. When the number of wireless microphones is too high, the wireless microphone should be placed on an average height and properly Make sure to position the singers and accompaniment as well as the position of the various instruments in the team, without overruns, lightness, and full sound at the effective angle of the wireless microphone.
Wireless microphone in use should prevent knocking or falling. It is not suitable to use the method of blowing air or tapping to test the microphone, otherwise it is very easy to damage the wireless microphone.
Wireless microphone When using or recording your voice outdoors, a draft shield should be used to avoid "pop" sound from entering the air. The draft shield also prevents dust from contaminating the wireless microphone.

With the popularization and widespread use of wireless microphone, how can we better play their superior role in the operation should pay attention to the following issues:
First, how to buy wireless microphone transmitter battery
In order to ensure the normal use of the system does not appear signal distortion and frequency interference, you must use the battery can be sufficient, if the conditions are optional, choose alkaline 9V battery.
Second, how can we know as soon as possible whether the transmitter battery energy is sufficient
In a variety of make and model of wireless microphone systems, the vast majority of receivers do not have the transmitter battery power display. Although some wireless transmitters have a battery low voltage display, the user generally seldom notices this problem in use. In the normal use of wireless microphone, there is a lack of battery caused by audio signal distortion or frequency interference is what happened. In order to prevent this phenomenon, the operator can use the mixer PFL pre-listening function in the normal use of the wireless microphone, and monitor the signal of the wireless microphone with the earphone. If the sound clarity is slightly reduced or the noise slightly increases , You should immediately replace the battery, so as to avoid as possible due to the lack of battery power to the operator of the psychological pressure.

Third, how to replace the battery halfway in the show
During the performance of the battery replacement should be convenient, fast and easy. It is a good idea to turn on the "dumb" switch of the console channel and leave the wireless microphone in a mute state. For example, a mixer without this function can turn off the output of the wireless microphone receiver and turn it off If the receiver does not output the volume switch, turn off the mixer input gain or use the Line / MIC selector to switch between the transmitter and the receiver, Turn on the battery after replacing the battery and then reset the mixer input gain or selector. Why not wireless microphone channel fader off and then replace the battery?

1. Try not to beat the microphone when the sound and the microphone inflatable
As the microphone part of the pickup more sophisticated, and the parts are very delicate, beat the microphone or blow to the microphone can easily cause damage or parts shift, the final impact on sound quality.
2 avoid microphone away from the source too far too close
Microphone pickup the best distance of about 10 cm. Some "leadership" speech is far away from the microphone, and some singers close to the microphone, resulting in excessive pickup sound too small, then push the volume fader up to easily lead to howling; too close to the speech Sound of air also picked up, issued a "puff puff" of the noise.

3. Avoid pulling the microphone lead
Avoid pulling the microphone lead when submitting the microphone. As the microphone has a certain weight, often pull the lead, it is easy to cause the lead off, the plug is not in good contact, resulting in pickup failure.
4. Do not turn off the use of good microphone power
Turn off the microphone switch at a meeting or after singing, when the sound controller does not turn off the mixer volume fader in time: on the one hand, it picks up the other noise and on the other hand, The necessary speech was broadcast. There was one such experience by President Bush, causing embarrassment.
5. Avoid mouth stick to the microphone to use
Some people use, do not pay attention or the pursuit of a near talk effect. Mouth often stick to the microphone, not knowing that this not only undermined the normal frequency response of the microphone, also caused a great health hazard, microphone network cover a lot of germs.

When To Use condenser microphone In Your Studio
Select the microphone, should be based on the use of the occasion and the sound quality requirements, combined with the characteristics of a variety of microphones, considering the selection. For example, high-quality recording and broadcasting, the main requirements of good sound quality, condenser microphone should be used, aluminum microphone or advanced moving coil microphone; for general amplification, the use of ordinary moving coil type can be; when the speaker moves from time to time Or talk with the megaphone distance greater, such as karaoke OK, should use unidirectional, low sensitivity microphone to reduce noise interference. The use of condenser microphone requires a phantom power supply. Generally, the supply voltage is indicated in the microphone's technical parameters. To select a phantom power supply of a suitable voltage, the mixer is equipped with a 48V phantom power supply.
In use should also pay attention to:
1, impedance matching
When using a microphone, the best match is the output impedance of the microphone and the input impedance of the amplifier. If the mismatch ratio is more than 3: 1, then the transmission will be affected. For example, the 50Ω microphone connected to the input impedance of 150Ω amplifier, although the output can increase nearly 7Db, but both high and low frequency sound will be a significant loss.

The BOYA BY-SM80 is a stereo X/Y condenser microphone that delivers broadcast quality stereo sound to your DSLR camera, video camera, or audio recorder. This microphone provides greater control of your audio than the internal mics on DSLR camera, video cameras, or digital recorders.
2, cable
Microphone output voltage is very low, in order to avoid loss and interference, the cable must be as short as possible, high-quality microphone should choose twisted pair metal shielded cable, the general microphone can be used single-core metal shielded cable. High-impedance microphone cable length should not exceed 5 meters, or treble will be a significant loss. Low impedance microphone connection can be extended to 30m-50m.
3, working distance and speaking effect
Usually, the working distance between the microphone and the mouth is between 750px and 1000px. If the distance is too long, the echo will increase and the noise will increase relatively. If the working distance is too short, the signal will be distorted because the signal is too strong.
