At Fitness Audio, we think that Fitness Instructors should be able to focus on delivering excellent classes instead of getting distracted by complex and temperamental audio equipment. It is for this reason that we design and manufacture gym and fitness centre sound systems that are very easy to set up, use, and pack up.
We do believe, however, that all Fitness Instructors should know the basics of how their microphone systems work. This way they are more readily equipped to tackle any issues in the rare chance that a complication does arise. Because of this, we have put together this simple guide on how wireless microphone systems work.
The Basics
Wireless mic systems have been a game changer for the fitness industry. They provide Fitness Instructors with greater freedom to move around so that they can demonstrate all exercises without being restricted by wires and cables.
The basic principle behind a wireless microphone system involves converting the audio input at the microphone into a radio signal that can be transmitted to a receiver and turned into an audio signal that can be played out by the speakers.
To do this, you need three pieces of equipment: a microphone, a transmitter, and a receiver.
The Microphone
Most Fitness Instructors are already aware of what a microphone is. The important thing to note, however, is that there are three types you can choose between in a wireless mic system. These include a handheld mic, a lapel mic, or a head worn mic.
If you’re looking for a microphone to teach a fitness class, you definitely want to go for a head worn mic. This will give you the greatest freedom to move around and prevent microphone feedback.
The Transmitter
Transmitters are the main point of difference between wireless and corded microphone systems. They work by capturing the audio input from your microphone and converting them into radio signals that can be detected by the receiver.
Like microphones, there are three main types of transmitters:
- Bodypack transmitters. These are worn on the body somewhere (usually in a mic belt).
- Headset transmitters. These attach directly onto the frame of your head worn microphone.
- Handheld transmitters. These are held in your hand or placed in your pocket (not recommended for Group Fitness Instructors).
The Receiver
Once the transmitter releases the radio signal, it will be picked up by your receiver where the carrier frequency will be decoded and recovered into audio. The receiver will then release this audio out through your speakers.
You should always look for a receiver that has two antennas. This allows your receiver to pick up the strongest signal possible from your transmitter to ensure good-quality, clear audio.
