What are the best budget wireless microphones for Smartphone ？

　　Many people think that choosing a good quality wireless microphone can avoid all kinds of interference. In fact the anti-jamming microphone and the quality of the microphone itself is not much direct contact. Only the correct use of wireless microphone can effectively extend the life of the microphone, to avoid errors caused by: microphone whistling, interference, sound quality distortion and damage to the microphone components.
　　When using a handheld wireless microphone, the distance between the microphone and the mouth is generally maintained at 5-10cm is better, too close to have a near talk effect, too far off the sound, will undermine the sound quality; in the use of lavalier microphone, to prevent Microphone too far away from the mouth, as close as possible to the mouth; use the headband microphone is to avoid the mouth is facing the microphone head, to avoid the impact of vocal airflow should be moved to both sides.
　　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 lack of battery caused by the audio signal distortion or frequency interference is what happened.

　　Stage audio equipment in many different types of audio, microphone (or wireless microphone ) + mixer + amplifier + speakers can be. In addition to the microphone source, sometimes also need DVD, computer music, etc., can also be used computer. But if it is to be a professional stage sound effects, in addition to the professional stage staff, plus effects, timing, equalizer, voltage limiter and other audio equipment. 　　A sound mixing device with multiple channel inputs, the sound of each channel can be processed separately and with left and right channels, mix, monitor, etc. output. Is the sound engineer, sound engineer and composer for music, sound important equipment. 　　The audio voltage signal is converted to a fixed power signal used to drive the speaker sound equipment. Power amplifier matching conditions. 　　 BY-LM400 Dual-Lavalier Microphone 　　The BOYA BY-LM400 is a dual-lavalier microphone is designed for recording interviews. With 3.5mm(1/8") TRRS connector

　　The performance of Wireless Microphone is often affected by various factors such as frequency interference, user error handling, and so on. This article will teach you how to avoid and prevent the most common wireless microphone problems. 　　When using Wireless microphone , there is always interference between the system itself. Although each system has frequencies or intervals of several megahertz, Intermodulation Distortion (IMD) can still cause interference between microphones. If there is not enough space between the intermodulation signal and the device's operating frequency, it is difficult for the receiver to pick up the signal from the transmitter. Typical phenomena are crosstalk between systems, frequent signal loss or excessive noise and distortion. 　　The minimum separation between frequencies depends on the design of the system receiver, which may require an interval of 1 MHz from the nearest neighbor. The more expensive receivers usually have narrower adj
