Functions and features

Although 4-channel wireless microphone systems differ regarding features, most of them have a few standard ones. They include;

• Number of receivers: Most wireless microphone systems have one receiver, but some can have up to four. A single receiver microphone can be integrated or standalone. It has multiple channels, and each channel corresponds to a different frequency used by the microphone transmitter. A single receiver can be used by connecting the receiver to the sound system or the device that the audio will be recorded on. An integrated receiver is built into the microphone's handheld transmitter.
• Transmitters and frequency bands: The microphone's transmitter is the part that sends the signal to the receiver, and the part that does so with the antenna is known as the transmitter. Depending on the model, some systems have transmitters that can be broad-band or narrow-band. Broad-band means the transmitter can operate on many frequency bands, while narrow-band means it can only operate on a few selected frequency bands. Narrow-band has better sound quality and longer range.
• Analog and digital output: The majority of wireless technology is analog. However, when the microphone's signal is transmitted, it will have some distortion, and the system should reduce that distortion to make the sound clear. The digital microphones provide clearer sound and are more preferred than the analog ones, even though they are costlier.
• Power supply: Wireless microphones usually have a Power supply system that runs on AA or AAA alkaline batteries or rechargeable NiMH batteries. Battery life is an essential consideration because long-battery life reduces the frequency with which the mic will need to be recharged or those batteries replaced.
• Sound quality and range: The sound quality is excellent if the 4-channel wireless mic system is among a high-standard grade. In high-grade microphones, the frequency response is between 20 Hz and 20 kHz, and the total harmonic distortion is around 0.5 percent or lower. The wireless microphone's range refers to the distance between the transmitter and receiver. Many of them will have a range of 100 to 300 feet.

Uses of 4 Channel Wireless Microphone Systems

4 channel wireless microphone systems are designed for more than just entertainment. They are used in different fields of work and play because they are efficient and flexible.
