Notifier DVC-EM — Digital Voice Command, Expanded Memory: the digital audio processor, message generator and router at the heart of a Notifier audio command center.
Each DVC carries up to eight audio channels, five firefighter telephone channels, and control of up to 32 Digital Audio Loop devices such as DAA2, DAX and DS-DB amplifiers. It is also the required control for a DVC-RPU. This is a board, not a finished console: chassis, cabinet, dress plate and microphone carry their own numbers.
