How to Connect a Microphone to Your CommBox Speakers

Applies To

CommBox Touchscreens, OPS PC, Premium Sound Bar

Step-by-Step Instructions

Step 1

Connect your microphone to your PC or OPS

• Plug your microphone into the 3.5mm input jack or USB port on your PC or OPS (the inbuilt PC inside your CommBox screen).

• This allows you to control audio settings, adjust EQ, and record directly from your computer.

💡 Tip: Connecting through the PC gives you more flexibility to adjust sound levels and record your voice during lessons or meetings.

Step 2

Adjust your microphone settings on your PC

• Go to Sound Settings on your Windows device.

• Select Input and choose your connected microphone.

• Test and adjust the volume and enhancements if needed.

Step 3

Optional: Connect directly to a CommBox Premium Sound Bar

• If you're using a CommBox Premium Sound Bar, you can plug a 3.5mm microphone directly into the sound bar’s AUX input.

• This provides a simple, plug-and-play option when you don’t need to adjust settings or record audio.

Troubleshooting / What to Do If It Doesn’t Work

• No sound from mic? Make sure the microphone is selected as the default input device in sound settings.

• Feedback or distortion? Lower the mic volume slightly and keep it away from the sound bar’s speakers.

• Sound not playing through CommBox speakers? Check that the PC or OPS is selected as the audio output device.
