Voice Amplifier For Instructors

Published March 20th, 2022

Written by WinBridge Team

Every instructor needs a voice amplifier to get his voice out loud and clear. From fitness instructors to sport instructor to all manner of activities, a voice amplifier plays a crucial role in communication.

Voice Amplifier For Instructors

Without the use of these devices, the instructor will find out that most of the time he teaches, he shouts at the top of his voice so as to be heard clearly. Shouting strains your vocal cords, which can result in permanent or temporary damage to them. This is why we recommend the WinBridge voice amplifier for every instructor.

In this guide, we shall examine voice amplifiers for instructors. We shall consider factors that are likely to influence the purchase of a voice amplifier, which include, budget, number of students, area size, and many others. We shall also conclude by recommending some of the best WinBridge voice amplifiers for instructors in today’s market.

Instructor’s budget for sound system

Budge and price are crucial to know before you decide to buy a voice amplifier. An excellent voice amplifier will cost anywhere from 50USD to 160USD, depending on the brand and model,
In addition, there are some factors that may increase the cost of getting a voice amplifier. These factors include inflation, delivery cost, tariff, and governmental policies. We recommend that the instruction consider and adequately budget for these facts before deciding to buy one.
Knowing how much to budget will shape what kind of voice amplifier the instructor is most likely to purchase.

Number of students

Instructors of a class must consider the number of students that will be present in the class before they decide to get a voice amplifier. Getting the wrong voice amplifier could mean that a section of the class will not hear you properly.

Furthermore, getting a powerful voice amplifier for a small class could cause the sound to be too overwhelming for them to use.

This is why we recommend for a smaller class of 30-80 students, a 5-10W voice amplifier will be more than enough for the class It also means that everyone in the class is carried along in the class.
For a large class with 80-120 students, we recommend getting a voice amplifier of 10-18 output power. these are more than enough to cover the entire class

Finally, for a class of more than 120 students, we recommend getting a voice amplifier with an output power of 20W plus.

Event venue area

When buying a voice amplifier the instructor must consider the size of the event area. The size of the event area will determine the time of the voice amplifier that will be needed. A larger room size will require a voice amplifier with larger output power in order to be useful. Mismatching the size of the venue with the output will distort the events.

As we know, various amplifiers come with different power outputs, and each of these voice amplifiers is ideal for different sizes of events that will be used. Now that we know this, you must understand the distance the voice amplifier will cover when used.
For a class of 40 meters in size, we recommend getting a voice amplifier with a power output of 5-10W. These are relatively small classes and do not require heavy-duty voice amplifiers.

Also, for a class of up to 80 meters, getting a voice amplifier with a power output of 10-18W will be suitable. In a position where the gym size is larger than 80 meters, a voice amplifier with a power output of 20W and above will be perfect.

The teaching time

The duration of the class should be carefully considered. These voice amplifiers all come with different battery lives. Some voice amplifiers are very useful for long use, while others were built for shorter events. To avoid a voice amplifier with a low battery, the instructor must consider how long the class will hold.
The duration of the instructor class will allow the instructors to make better decisions when they are ready to buy a voice amplifier… Voice amplifiers do not have the same battery capacity. Voice amplifiers come with varying battery life, which serves different events.
For a class that is more than 8 hours of consecutive use, we recommend that you buy a 20W voice amplifier, which will work for 10 to 20 hours when fully charged. A voice amplifier with 20W will take about 3 hours to have a full charge.
For a class that is less than 8 hours a day, we recommend a 15W, supported with a wireless microphone that can last 5 hours when fully charged.
It is also important to note that the wired voice amplifiers have a better battery life than the wired voice amplifiers

Assistant instructor

Where there is an assistant instructor, we recommend that the instructor gets a tow headset microphone amplifier for the class. One will be assigned to each instructor, so they can make their contribution.
A wireless headset and voice amplifier are most suitable, as they are convenient for use and allow the instructor to easily move around during the lectures. We recommend the WinBridge S92 Plus. The S93 Plus comes with two wireless headset microphones.

Run back and forth

Movement is an important part of every instructor s activities. from the fitness instructor, he may be required to move frequently and bend over to carry out many of the fitness exercises. This means that the instructor will need a voice amplifier that offers him flexibility and is very lightweight
We recommend a wireless voice amplifier that is very portable to carry around. At best, those voice amplifiers come with belt straps and clips, so that the amplifier can be attached to the body of the instructor.
The device must be very lightweight, in order to be used for activities that require lots of movement.

Wired microphone for instructors

Both the wired and the wireless voice amplifier comes with their pro and cons. They are suitable for unique situations. If you are still confused as to whether to get a wired microphone, here is a list of advantages, disadvantages, and applications of a wired voice amplifier. All of which should be considered before the purchase of a wired mic.
Advantages of a wired microphone
1. clearer sounds:
The significant advantage of using a wired microphone headset voice amplifier is that it produces a much clearer sound.
2. Output power:
Wired voice amplifiers usually have a much higher output power and battery life than wireless mic voice amplifiers.
3. Lightweight
Also, the wired mic amplifiers are fairly lightweight, making them easy to carry around by the speaker.

4. Easy handling:
Talking about ease, the wired voice amplifier comes with a belt strap that can be adjusted for the convenience of the user.
In addition, wired microphones produce a clear sound output in comparison to wireless microphones. This is because its amplifiers usually have high output power.
5. Easy controls
the controls are close to the speaker, easily reducing or increasing the speaker’s volume without any stress.
Disadvantages of Wired microphones
The following are the major disadvantages of a wired microphone.
1. It is unsuitable for strenuous movements and may not be suitable for yoga classes.
2. It could also be uncomfortable for the users as they may not like the straps and belt clip.
We do not recommend wired microphones classes that require extreme movements;

Wireless Lavalier Microphone for instructors

The wireless lavalier microphone is a tiny microphone with a receiver connected to other pa systems and attached to the speaker’s body to help amplify his voice. Now, the receiver of this microphone can be connected to any mic jack or UHF wireless signal transfer from a microphone to the receiver making the device a wireless amplifier.

Interact with the students

For interaction between students and instructor, we recommend a double mic wireless headset and handheld microphone. These are best for interaction between students and instructors. Instructors can easily communicate with students with a suitable voice amplifier with the right voice amplifier. We recommend getting a wireless amplifier with two wireless microphones for easier and more proper interaction between the fitness instructor and the students. One microphone will be used by the instructor, while the students will use the other.
Using a wireless amplifier with two wireless microphones will save cost rather than buying two amplifiers. You can also connect the amplifier to other devices like a phone or an iPod via Bluetooth to play music.
If the fitness program is not interactive, you can buy an amplifier with a single wireless microphone.

On-the-spot teaching with a mask

With the advent of the covid-19, wearing a nose mask has become part of our way of life. We are now required to wear our face masks when we are in public places. Obviously, these masks across our mouth and nose hinder and distort proper communication.
The teacher who wears a face mask to teach will notice that his/her voice is very low and unclear, which may lead to misinformation or loss of interest by students in the class. We recommend getting a voice amplifier of at least 5W in order to amplify the voice of the teacher /instructor. These masks also prevent the students from seeing the facial expression of their teachers/instructors.

Waterproof, anti-fall, and rugged voice amplifier

Instructors should ensure that whatever voice amplifier they buy is waterproof anti-fall and rugged. It is important that they don’t buy less quality voice amplifiers that will easily get damaged.
WinBridge voice amplifier offers the best voice amplifier made with the highest quality of materials. They are designed with anti-fall features which use belts and straps to adequately protect the voice amplifier from sustaining damages when they fall.
Also, the instructor should ensure the voice amplifier are waterproof so that they can be used outdoors, even during rainy sessions
WinBridge voice amplifiers use the best quality materials to build their speakers. The WinBridge speakers are highly durable and will last for a long time.

Voice amplifier for outdoor instructors

For outdoor events, the instructor must consider factors such as weatherproof, durability, and even battery life. It is crucial that the instructor get a voice amplifier that is weatherproof, especially waterproof. This is because outdoor events are prone to changing wethers that can damage the voice amplifier.
Also, the instructor should ensure that the voice amplifier has the required battery life needed for outdoor events. Preferably, we recommend picking a 20W plus voice amplifier for these events, as they offer much reach and a better battery life

Voice amplifier for damaged vocal cord
