Classroom audio: soundbars, speakers and microphones

Please note: this is independent guidance. Vision Tech is not affiliated with Clevertouch. Menus and features differ between models and software versions, so check your screen's own manual or on-screen help, and speak to your school IT team or supplier before changing admin-locked settings, updating firmware or doing a factory reset.

Good sound matters as much as a good picture. Interactive screens usually have built-in speakers, but a classroom or meeting room may also have a soundbar, separate speakers or a microphone.

What your room may have

Rooms vary. Some have only the screen's speakers. Others have a soundbar fixed below the screen, ceiling speakers, a wireless microphone or a conference microphone on the table. Ask your IT team what is fitted in your room.

Check the basics

  1. Switch on any separate speakers or amplifiers. They often have their own power and volume controls.
  2. Raise the volume on the screen and on the speakers.
  3. Check mute is off.
  4. Check the connection. Soundbars usually connect by an audio lead, HDMI or Bluetooth.

Laptop sound

When you use a laptop, choose the right sound output on it. It should be the screen, HDMI or the soundbar, not the laptop speakers. See our guide on no sound.

Microphones

  • Wireless microphones need charged batteries or a charged pack. Switch them on and check the receiver light.
  • Keep the microphone away from speakers to stop whistling feedback.
  • Test the microphone before the lesson or meeting starts.

When to get more help

If sound is crackly, cuts out, or the soundbar will not pair, tell your IT team. Give them the make of the device, if known, and what it is connected to. If the screen is managed by your school or company, some settings may be locked. Your IT team or the supplier you bought the screen from can help with warranty, firmware and admin-locked settings.

Did this help? If you are still stuck, email Vision Tech and tell us what you can see on the screen. Menus and button names can differ slightly between versions and makes. If something does not match, stop and ask rather than guess.
