Many wireless systems use a process called companding that compresses the transmitted audio signal at the microphone then expands it at the receiver to restore the dynamic range of the audio. This is done to deal with the limited capacity of wireless channels. Other circuitry is used to detect and remove noise from the transmitted sign...

Virtually all pro wireless systems operate on either the VHF (very high frequency) or UHF (ultra high frequency) bands. VHF wireless systems generally operate within the 174 to 216MHz range (the range of TV channels 7-13), while UHF uses the 470 to 805MHz range (the range for TV channels 14-69).Traditionally, UHF has been used by highe...

Wireless Microphone System Components All wireless mic systems, regardless of their applications, are made up of two basic components: transmitters and receivers. Transmitters convert the audio signal captured by the mic into a radio signal. These are then sent to a receiver that co...
