Wireless Microphone System Frequency Range
UHF-TV Band
Unused television channels in this range are available for wireless microphones and other wireless audio devices. Most cities have a significant number of television stations and the largest cities may also have public safety operations, but there are sufficient unused television channels available for most wireless users to find a clear channel. Users may be licensed or unlicensed in the UHF Band.
900 MHz Range
This band (specifically, 902 – 928 MHz) offers additional channels outside of the TV channel range. Users are allowed to operate without a license in this range. There are several high quality wireless microphone systems that operate in this range, most of them fully digital.
2.4 GHz Band
Advantages of this band are: worldwide, license-free operation, and very short antennas, but there is some potential for interference from Wi-Fi devices.
Wireless Microphone System Startup Guide
Turn on your receiver while the transmitter is still powered off. Most wireless receivers have an "Automatic Frequency Selection" function — press that button, and your receiver will assign itself a frequency.
Most wireless transmitters have a button that will make them synchronize with the receiver that you just turned on (once the receiver has chosen a frequency). Press this button, and the transmitter will shake hands with (connect to) the receiver that you just set up.
Check the signal levels at the transmitter and at the receiver to make sure that you're getting a good signal without any distortion.
Make sure that you don't cover the antenna on the transmitter. Hold your handheld mic closer to its capsule to avoid covering its internal antenna, and make sure that the external antenna on your bodypack isn't wadded up or bent.
Maintain line of sight between your transmitter and receiver. Placing the bodypack on the front of the person using a headset or lavalier mic (rather than on their back) helps as well — human bodies are lousy RF conductors.
Be mindful of your system's operating range, and place transmitters and receivers as close to one another as possible. The more distance a signal has to travel, the greater chance for interference.
Keep fresh batteries in your transmitter. As a battery dies, signal strength and operating range begin to dwindle.
