What is a wireless mic?

The wireless system is a miniature radio station, replacing either the mic cable or an instrument cable.

Parts of the microphone system

Although the wireless setups may differ, all will be comprised of the same components:

The transmitter will convert the AF or audio from an input device, from a handheld or headset microphone to radio frequency (RF), then send it to the receiver. When using the microphone connected to a belt pack with an external antenna, ensure the antenna is not wadded up or bent when wearing it. The situation must be paid attention to, not to affect the antenna as it can severely impair the transmission.
The receiver is the box where the antenna is built, which connects to the mixer. It will receive the radio signal that changes back into the audio signal that is sent to the input of the mixing board using either instrument cable or XLR.

Wireless systems are common in places, such as:

They save time and space by stopping the need to use and tie up multiple cables.

What is a good wireless microphone?

The choice of a good wireless microphone covers unique considerations and popular options in different categories:

Purpose:
- Vocal performance. If you need a microphone for singing or speaking on stage, a handheld dynamic wireless microphone is a common choice.
- Presentations. For public speaking, lavalier (clip-on) or headset microphones are convenient.
Frequency range. Ensure the microphone’s frequency range is compatible with the location and intended use. Some countries have specific frequency bands allocated for wireless microphones.
Wireless technology. Ultra High Frequency and Very High Frequency systems are common choices. UHF is preferred for its greater range and interference resistance.
Microphone type:
- Dynamic microphones. Durable and suitable for live performances. The Shure SM58 and Sennheiser e935 are popular options.
  - Condenser microphones. Deliver high-quality sound but are more sensitive and require phantom power. Sennheiser EW 135 G4 is a well-regarded wireless condenser mic.
Interference resistance. Start to look for systems with advanced interference resistance features, such as frequency agility and automatic channel scanning.
Battery life. Consider the microphone and receiver’s battery life, especially for long events. Some models offer rechargeable batteries.
Range. Ensure the microphone’s operating range is sufficient for your needs, especially if you need to move around during your performance or presentation.
