Design Manual

To handle these requirements, the contractor decides to use two DSP boxes – one handles the eight
incoming music and television signals while the other handles the microphone mixing and zone processing.
Inputs to the zone processing/microphone mixing DSP box are limited to two CobraNet Bundles. One of
these Bundles is used for receipt of the music/television channels. This leaves only one Bundle for receipt
of the microphone signals from both the student union and the cafeteria. Without the Mongoose, this
would be impossible and an additional DSP box would need to be purchased. Using Mongoose technology,
however, you can combine the microphone signals from disparate locations into a single CobraNet Bundle,
eliminating the need for that additional DSP box. The floor plan drawing illustrates how this is done:
