What Is a PA System Microphone?

PA systems are used in a wide range of venues and applications from clubs and leisure centres to arenas. They convert acoustic sound into electronic signals for amplification via microphones, mixers and loudspeakers. Different PA equipment has varying capabilities, features and designs to best suit your needs and budget.

For vocals a PA system microphone is the most critical piece of equipment as it’s responsible for converting sound pressure into an electrical signal. This is achieved by a diaphragm moving back and forth in response to sound pressure changes. The resulting voltage is then amplified by a power amplifier. The amplification process can create standing wave frequencies at the output of the speakers that, when coupled with close proximity to the microphone, can trigger acoustic feedback with severe ringing and howling noises.

Rechargeable Wireless Microphone

If you’re in the market for a new rechargeable wireless microphone, there are some things you should know before buying one. You want to make sure you’re getting a quality product and that it will work well with the rest of your equipment. You also want to be able to charge it properly so it doesn’t drain the battery too fast.

This rechargeable wireless microphone uses UHF frequencies to broadcast a clear and crisp signal. Its frequency is not subject to interference from other devices, and it has a maximum operating range of up to 200 feet. It features a cardioid pickup pattern that will minimize feedback and background noise.

Buying a Table Microphone

A table microphone — also known as a conference mic or desk microphone — is a versatile solution for video calls, podcasting and more. They’re designed to sit on top of a desk or conference table, with some models also fitting onto a lectern. These microphones feature a wide range of functions, from multifunctional controls to multiple pickup patterns. Some even include a high-pass filter to remove low frequencies that can cause rumble or humming in recordings.

The main thing to consider when selecting a table mic is its pickup pattern – or polar pattern – which determines the area it covers and where sound will be picked up from. A unidirectional microphone is ideal for recording one person, with a cardioid or bi-directional mic better for two-person conversations (think across the table podcast chats). Some of these microphones can even switch between pickup patterns to best suit your needs, whether that’s switching between omnidirectional and stereo to record a room full of people or switching to figure-8 mode to capture guitars or other instruments.
