FORMULA SOUND AT-1 WALL -  Automatic Volume Level Control Unit, Wall/Surface Mountable -
The AT-1 Wall has been designed to be installed onto a wall or flat surface and used in conjunction with the SENTRY MK2 environmental noise control unit. It is a digitally controlled stereo unit and its purpose is to control the volume level of an audio system connected to it, without cutting off the system completely. It will control the connected system to the maximum level allowed as defined by the Sentry Mk2, thus removing the worry of having to continually watch levels. It does this without affecting the dynamic range of the music being played, and because the control chain is microphone driven the amount of absorption which takes place when a venue is full of people is automatically catered for.
