A professional wireless microphone system consists of three main parts:
- an input source
- a transmitter
- a receiver
The input source delivers an audio signal to the transmitter, converting the audio signal to a radio signal, and then transmits it to its surroundings. The receiver acquires the radio signal and transforms it back into an audio signal. It is a comprehensive process that makes parts of a microphone wireless system. The other system components may include:
- antennas
- distribution systems
The process and the basic elements are functionally comparable to radio communications. What varies is the component size and the physical system configurations.
4 professional wireless mic systems setups
There are 4 wireless microphone system setups available. It has the mobility of the transmitter and receiver and is for different usages
- Standard wireless mic system
- Wireless system
- Wireless intercoms system
- Point-to-point wireless system
Standard wireless microphone system
It is composed of a portable transmitter and a stationary receiver. The user can hold the transmitter anywhere, free to walk around. The input source in this set-up is a mic. The receiver output is sent to a recording equipment or sound system. It is the arrangement suitable for:
- live streaming
- public speaking
- broadcasting
Professional dual-channel wireless microphone systems are for two-person recording without the limitation of cables.
Wireless system with stationary transmitter and portable receiver
Opposite to the standard composition, the user will carry the wireless mic receiver, while it has a fixed transmitter. The input source connected to the transmitter for this setup is the following:
- sound system
- playback system
- other installed source
The receiver’s output in this case is always monitored using loudspeakers or headphones. The wireless microphone system is built for in-ear monitoring, accompanying interpreting, and instructional usefulness.
Wireless intercoms system
A wireless intercom system that carries a portable transmitter and receiver. Each component user has the freedom to move. In the setup, the input source is a mic and the output is a headphone. Each user has a transmitter and a receiver for 2-way communication.
Also, it is used to transmit audio from the professional wireless mic to a portable camera or recorder for the following:
- broadcasting
- filming
- video making
Point-to-point wireless system
The system holds a stationary transmitter and receiver. The input source is a mixer or playback while the receiver output is a sound system or broadcasting facility. Examples of this professional wireless mic system are non-commercial or commercial broadcasts from fixed transmitters to fixed receivers.
