This simple and effective 3D-printed cover is designed to lock your mixer’s EQ and gain/level settings in place, preventing accidental or unwanted changes during live events, installations, or rentals.

The cover is made from a single solid piece that fits directly over the potentiometer knobs (no tools or mounting hardware needed).

It is held in place by the knobs themselves, making it easy to install and remove without damaging the mixer.

Compatible with configurations of 2, 3, 4, or 5 adjacent potentiometers, this is a universal solution for most compact and medium-sized audio mixers.

Ideal for DJs, sound techs, or venues that need reliable and consistent mixer settings. Durable, lightweight, and hassle-free.
