The Relay Switchbox USB from PunchLight is a small, USB-powered unit with two built-in switching relays. The unit can control any signaling systems that arealready installed in your studio. You can control other devices such as speakers, a microphone, or your own light system with this box. The Relay Switchbox USB can work without a power supply, as it is connected and powered via a 5V USB port.

The Relay Switchbox USB is designed for anybody working in project, dubbing, or post production studios that needs visual confirmation of when a recording begins or ends. This simple, precise, and easy to use device is ideal for musicians and sound engineers as well as film, TV, and video editors. It is easy to install in any studio environment.

It is possible to connect an additional external light, such as the PunchLight RECORDING Display, RECORDING PlexSign, RECORDING Ring, or RECORDING Lamp, though a 12V power supply will be needed (all sold separately). The unit is compatible with most audio applications such as Pro Tools, Cubase, Logic Pro, Digital Performer, Samplitude, Reaper, Sonar, and Vegas Pro. The software automatically sends information about Recording start/stop and record "ready" to the Relay Switchbox USB. All functions are set up via the PunchLight Software Utility.
