If you call a Pleneo room and the audio doesn’t feel stable,
volume may shift. Voices may rise and fall unexpectedly.

No need to worry.

This is often caused by Automatic Gain Control (AGC) being active on a microphone.

AGC continuously adjusts microphone levels.
In a Pleneo system, that behavior isn’t needed.

When AGC is enabled, the system and the microphone both try to control volume.
At the same time.

You might experience:

• Volume that jumps during speech

• Audio that feels like it’s “pumping”

• Voices that sound uneven or inconsistent

• A room that feels unpredictable

Instead of smooth, balanced sound, the experience becomes unstable.

Pleneo already manages audio levels automatically.
It’s designed to control the full signal path.

AGC introduces a second layer of adjustment.
Two systems. One task.

The result is conflict.
And that conflict is heard as shifting volume.

Turn off AGC on the microphone.

In most cases:

• AGC is already disabled by default

• No additional setup is required

If you hear uneven volume, this is the first setting to check.

With AGC disabled:

• Volume stays consistent

• Speech sounds natural

• The room feels stable

• Audio behaves as expected

Everything aligns.
Everything just works.

Pleneo Room OS is built to manage audio end to end.
From microphone input to speaker output.

No overlap. No interference.

Disabling AGC allows the system to perform exactly as designed.

Uneven volume is often caused by AGC being enabled.

Key takeaways:

• AGC automatically adjusts microphone levels

• Pleneo already manages audio internally

• Running both creates unstable sound

• Turn off AGC to restore consistency

Check the microphone.
Disable AGC.
Let Pleneo Room OS handle the rest.
