A microphone is an electronic instrument with the function of converting sound waves into electrical
energy variations, which can then be amplified, transmitted, or recorded. A wireless
microphone is one without a physical cable connecting it directly to the sound
recording or amplifying equipment. A wireless mic 4 channel is a set of four wireless
microphones that can be channeled simultaneously.
Uses of a wireless mic with four channels.
Wireless microphones are adversely used in the entertainment industry, broadcasting, and
public speaking to freely move around while using the microphone without requiring a cable
attached to them. The four microphones wirelessly connected to each other enable four different
speakers in 4 different locations within a limited vicinity to communicate simultaneously at
the same time. This cancels the time required to transfer one mic from one user to the other.
This also saves the user the amounts required to buy four singular mics. Instead, the inter-
connected mics are purchased as a set.
The set of the 4-channel mic can be greatly used in meetings and plays where more than one
speaker is expected to talk at a particular moment in the event. The wirelessness also brings
about the aspect of neatness. Neatness is experienced when no wires are coiling around the
speaker’s environment due to the connection between the mic and the mixer. The
wirelessness also allows for free movement over a greater length without interfering with the
Features to consider when choosing a wireless microphone
The Ultra-High Frequency of 400 MHz and above has been the standard for wireless
microphone’s strongest and best performance. It is important to note that the 2.4GHz
frequency band is the same as Wi-Fi and is subject to interference from microwave ovens.
Their operating range is also much shorter. It is important to only use 2.4GHz wireless
microphones in smaller rooms with no obstructions between the transmitter and receiver
It is important to choose a wireless mic system with a stated operating range twice the
distance intended to operate. It is realized that wireless mic systems that have short operating
distances have interference problems. Short-range wireless systems do not transmit
well through slight barriers. With a microphone of a larger operating range, usability is
Overall Sound Quality
The digital wireless mic systems are the most marketable microphones as compared to analog
wireless systems. This is due to their outstanding performances in battery life areas, which
can be twice as efficient as those from analog mics and the wireless microphone spectral
efficiency. Generally, digital wireless microphones have a better and improved sound quality
as compared to analog microphones.
Digital systems can transmit a consistent digital signal that provides full dynamic
range without using a companion. This results in a more natural sound. Price drops in digital
wireless microphone systems have made it affordable for almost everyone to purchase. Some
microphone systems will even allow you to make adjustments to the transmitter from a computer
connected to the receiver.
