Number of Students
Customers can choose the power of the amplifier by the number of students in their classroom. The power of different amplifiers varies, as well as the effect and quality of amplification. So teachers of different ages can choose the most suitable amplifiers for themselves by their teaching scenarios and the number of students in their classes.

For kindergarten teachers, our recommended amplifier is the output power of the 5-10W amplifier, the reason for the recommendation is that the output power of the 5-10W amplifier is suitable for the number of students is 30-80, the number of kindergartens is generally in this range, so this type of amplifier is the most suitable.

According to the size of the primary/secondary school classroom and the number of students in the classroom, we recommend 10-18W amplifiers for primary/secondary school teachers, because the number of students applying to amplifiers with an output power of 10-18W is 80-120, and the classrooms and number of students in primary and secondary schools are generally within this range, so this type of amplifier is the most suitable.

For the number of students at university or outdoor teaching, we recommend 20W and above amplifiers for university or outdoor teaching teachers, as these high-power amplifiers allow 180 people to hear clearly.

The Amplifier Classroom Area
Before shopping for a voice amplifier, consumers need to know how much area the number of teachers and students. Because different power amplifiers’ amplification effect is not the same, the area of amplification is also different. Classroom area related to the amplifier output power and sound transmission distance, but also the consumer needs to consider. These are also the parameters of the amplifier, different power amplifiers, these parameters are not the same.

First of all, for kindergarten teachers, Our recommended amplifiers are the output power 5-10W amplifiers, the reasons for the recommendation are that the output power 5-10W amplifier is suitable for the applicable site area is within 40 meters, kindergarten classrooms, and the number of people generally in this range, so this type of power amplifier is the most suitable.

Depending on the size of the primary/secondary school classroom and the number of students in the classroom, we recommend 10-18W amplifiers for primary/secondary school teachers, because the applicable site area is within 80 meters, and the classrooms and numbers of primary and secondary schools are generally within this range, so this type of power amplifier is the most suitable.

Depending on the size of the university or outdoor classroom and the number of students in the classroom, we recommend 20W and 20W+ amplifiers for teachers in university or outdoor teaching scenarios because of the long sound transmission distance of these high-powered amplifiers, which can reach 1000 square feet.

In the face of customer amplification in different teaching scenarios, we recommend the use of different amplifiers. Teaching scenes can be divided into indoor or outdoor. Indoor according to the use of the area and the number of people to choose the right amplifier, outdoor according to whether the movement, will not be easy to fall and other considerations to choose the right amplifier.

In the face of outdoor teaching, our most recommended is a fall-proof, waterproof, and dustproof amplifier.

whether to interact with students in the classroom

In the face of interaction in the classroom, we recommend two choices of microphone amplifiers to teachers. By whether the teacher and students interact, teachers choose whether to buy this amplifier with two wireless microphones. The biggest feature of this amplifier is that it can be connected to two wireless microphones at the same time so that the teacher can use the wireless microphone in the classroom to lecture and ask questions to students, and the following students use the wireless microphone to answer, which plays a good effect on the interaction in the classroom.

The amplifier with two wireless microphones also has the function of Bluetooth, which can be used to play music through Bluetooth devices such as cell phones and computers. Students and teachers can sing and read aloud together through the wireless microphone, which can bring interaction and a great help to teach, while inserting U disk and TF card can also play music, without the use of special Bluetooth devices.

If you need to interact with students in the classroom, you need to buy an amplifier with two wireless microphones, if you do not need to interact with students in the classroom, you only need to buy an amplifier with one microphone.

Voice Amplifier for teaching offline and online at the same time

Due to the global pandemic, the teachers are one of those who faced difficulty and challenges when teaching to their students. Today, classes are done either offline or online. If there’s one helpful gadget that assisted teachers during this time, they are the voice amplifiers!

Voice Amplifiers can assist teachers in the new normal manner of teaching in the following ways:

Speak loud and clear.
Voice Amplifiers will assist teachers in exerting less effort in their delivery of teachings to be discussed with their students. Voice amplifiers will perform the work for them instead of giving their lectures loudly or manually amplifying their voices. As a result, teachers will not strain their voices while giving lessons since they can speak quietly, and the voice amplifier will deliver a clear and loud message to the students.

Reduce your mental stress.

One of the most formidable obstacles that a teacher must overcome is stress. It’s impossible to avoid, especially when pupils don’t receive or understand what the teacher is saying, resulting in a barrage of questions. However, it may have an impact on their ability to teach in the future. Voice amplifiers can reduce mental stress since they will present lectures to the students loud and clear, and the teacher will have confidence in all of their efforts in discussing how well the students understood the lessons.

Learning that is more efficient.

Teachers can deliver loud and clear lessons to pupils by utilizing the voice amplifier, which provides the highest audio quality for improved learning. Students will be able to hear the information without any sound barriers, typically caused by low-quality audio output from some microphones on teachers’ devices.

Examples include those utilized in online classes, which will be established as the ‘new normal’ mode of schooling in pandemic situations.

The presentation is similar to that of a classroom.

Suppose the teacher prefers to use a chalkboard, whiteboard, charts, or any other teaching approach. In that case, the Voice Amplifier can be worn on the waistband and used to discuss the lesson with the connected microphone if the teacher has a board at home. Because the Voice

the Amplifier is also equipped with Bluetooth, the teacher can use the wireless microphone. The teacher can pick between the two options based on their preferences.

Voice Amplifier for a Music Teacher
Music teachers need to emphasize their lesson by talking clearly and with the right volume in class. But, when they talk aloud, it can cause fatigue in their throat area that can give them voice problems. Thus, they need to keep muscle stress to a minimum.

The esophageal muscle is considerably affected when we converse for an extended period, especially with music teachers who offer lessons to their students for several hours. Teachers will not need to shout for students to understand clearly what is being said if they use a voice amplifier. Teachers will be able to give their students the finest education possible by staying in good shape.

With the help of voice amplifiers, music teachers can now enjoy teaching while protecting their voice. The Voice Amplifier is equipped with USB Aux, wherein you can connect it to your laptop or desktop to give a power supply. While the voice amplifier is connected to your device, it is also charging power to itself, so you do not need to worry about the amplifier’s capability. Teachers can use the amplifier for their entire class schedule.

Always invest in a good headset and sound equipment. Clear audio is critical when teaching. Get a good microphone, preferably with a wireless headset so your students can hear you loud and clear and you can hear them as well, whether you’re doing a live class or recorded one.
