Microphone Gain

This browser cannot talk to the microphone.

Adjusting the gain needs WebHID, which today means Chrome, Edge or Opera on a computer. Safari and Firefox do not implement it, and no browser on a phone or tablet does — including Chrome on Android.

This unit has no gain control.

Its firmware does not carry the control channel the gain setting lives on, so nothing on the host side can reach it. This is a property of the unit, not of this page or your browser.
