Tempest Belt Stations have wireless ISO. Wireless ISO lets a Belt Station user talk only to other wireless belts on their channel. When enabled, a Belt Station user can push the Enter button to activate Wireless ISO. This enables the user’s Microphone and routes the audio to all other wireless Belt Stations on the active channel. The wireless user’s audio does not go to the hardwired intercom for as long as the Enter button is pressed. This feature is great for stage managers and other situations where “offline” conversations are necessary. Tempest gives you the tools to get the job done!
