How to Use Audio Control for Classroom Teaching



Audio control can be an important part of a classroom environment. That’s why we’ve compiled this list of tools to help you learn how to use them effectively. In no particular order, here are some of the most useful audio control tools for teachers:


You can also use a microphone to amplify sound. A simple amplifier, mixer, and Q-NEX NMP are used to control the volume level of the voice of a speaker or singer. This system works well but has some limitations:

  • The quality of sound will be poor unless you have good speakers and amplifiers. If you have low-quality equipment, it’s better not to use this method because it will make your voice sound terrible!
  • You can only amplify one person at a time using this method (this means there is no way for people in other classrooms or buildings on campus to hear what’s going on).


A speaker is an electro-acoustic transducer that converts electrical energy into sound. A speaker’s sound quality is determined by the frequency response of its audio circuitry, which must be designed with a flat frequency response if the best possible sound quality is to be achieved.

Speakers are typically boxed enclosures containing one or more drivers (a driver being an individual transducer that converts electrical energy into acoustic energy). The enclosure may be vented to improve bass response or sealed to attenuate it, depending on what kind of enclosure you choose.


Amplifier : An amplifier is a device that increases the power of a signal. Amplifiers are used in audio, video and radio systems to increase the voltage or current.


A mixer is a device that combines several audio signals into one signal. It can be used to control the volume and other characteristics of the sound.

Q-NEX networked media processor (NMP)

Q-NEX NMP is short for Networked Media Processor, and it is mainly designed for assisting school’s IT admin to well manage various electronic facilities in a school, and freeing teachers from complicated operation of a multimedia classroom.

One of the main purposes of Q-NEX NMP is to provide an intuitive and easy-to-use interface for teachers to use. Teachers can easily control the digital content in their classrooms with just one touch, such as playing video clips or turning on projectors.

In addition, teachers can also view the real-time status of all digital devices in their rooms via a dashboard interface. They can easily identify which device has malfunctioned and troubleshoot accordingly.

CD player/recorder and turntables

You can connect a CD player/recorder and turntables to the mixer. This will allow you to play music, audio files, or anything else you want through the speakers in your classroom.

To do this:

  • Connect an RCA cable from the “”CD”” input on your mixer to either of the RCA inputs on your CD player/recorder (or cassette deck). If there are any other inputs on your device that have an RCA plug, like an AUX input or something similar, use them instead—it won’t hurt anything if these are connected at this point! The only thing that matters is that there’s a physical connection between these devices for now; don’t worry about sound quality yet!
  • Turn up all volume dials so they’re not muted (if applicable). You may need some help getting this right—don’t worry if it doesn’t work right away though! Just try again later when everyone has gotten used to using their new equipment

audio control

Audio control is the use of a networking media processor, which can be combined with hardware like microphones, speakers, amplifiers, and mixers. You may also want to add other hardware (like a digital signal processor) or software that will make your audio experience better.

When you’re choosing an audio control system for your classroom teaching environment, think about what you need it to do:

  • Is there an existing amplifier that you can connect directly to the network?
  • Where are your microphones located? Do they need to be near where students are sitting or in the back of the room where teachers sit? If so, how far apart?
  • How many more microphones do you plan on having in addition to those connected directly through their own sound cards on computers?


audio control is a valuable tool for teachers and students alike. With the right equipment, you can make your classroom more conducive to learning by making sure that everyone can hear and understand what’s being said.
