The AirTurn BT500S-4 Controller is a professional wireless Bluetooth footswitch designed for hands-free control of apps, software, and digital devices during live performances, studio sessions, or presentations.

Featuring four durable steel switches in a stompbox-style layout, the BT500S-4 enables you to turn digital sheet music pages, start or stop backing tracks, trigger effects, send MIDI commands, control DAWs, teleprompters, lighting software, and more — without using your hands.

The controller connects wirelessly via Bluetooth (range up to 200+ ft / 60+ m) to smartphones, tablets, and computers, and offers over 200 hours of operation on a single charge thanks to its built-in rechargeable battery. Custom commands such as keystrokes, macros, and MIDI messages can be easily assigned using the AirTurn Manager app.

Built from a rugged polymer blend housing with industrial-grade switches, the BT500S-4 is designed for demanding stage use while remaining lightweight and pedalboard-friendly.
