The Relay SwitchBox USB is a small USB powered unit with two built-in switching relays. The unit can control any signalling systems already installed in the studio. You can control any other device, e.g. speakers, a microphone or even your own light system via just one small box. The Relay Switch Box USB can work without a power supply, as it is connected and powered via just an USB port.

Compatible with Pro Tools, Cubase, Nuendo, Logic Pro and most other audio/MIDI applications.
