Components:
Microphone: Captures the sound waves and converts them into electrical signals. 
Transmitter: Sends the audio signal wirelessly to the receiver. 
Receiver: Receives the transmitted signal and outputs it to the audio equipment. 
Key Specifications:
Frequency Range: Determines the range of frequencies the microphone can transmit and receive, often categorized as VHF or UHF, with UHF generally offering more channels. 
Microphone Element: Different types like dynamic or condenser microphones have varying characteristics regarding sensitivity and frequency response. 
Output Power: Affects the range and signal strength of the wireless transmission. 
Battery Life: Indicates how long the microphone can operate on a single charge or set of batteries. 
Sensitivity: Measures the microphone's ability to convert sound pressure into electrical voltage. 
Maximum Input Level: Indicates the highest sound pressure level the microphone can handle before distortion. 
Signal-to-Noise Ratio: The ratio of desired signal to background noise, affecting clarity. 
Operating Range: The maximum distance between the microphone and receiver.
