Example Applications
This section includes several example audio designs utilizing the Mongoose system. Each example includes
a generic one-line audio design, a detailed floor plan incorporating the Mongoose technology, and a shop
drawing (similar to the one-line drawing but with Mongoose equipment specified). Each example also
includes a link to its corresponding Mongoose Tracker configuration file (on the Rane website). You must
use the Mongoose Tracker application to open and view these configuration files.
We’ll begin with the simplest design – a tie-line.
RAD to RAD Using a Single Mongoose (Tie-Line)
This example involves the Saint Dawkins Church, which has a congregation of about 2000 people. The main
sanctuary of the church holds 1300 people, so there is occasionally an overflow problem. It happens rarely,
however, so the church board has decided against the expensive proposition of enlarging the sanctuary.
Instead, they want to use the large meeting room in the church school building across the street to house
overflow congregation members. They plan to install a projection system that will transmit the audio from
the sanctuary to this meeting room.
Mongoose technology is perfect for this situation. Since the meeting room is across the street from the
church (and the source of the audio signal), installing analog cables could prove problematic. Even with
the addition of isolation transformers, there is absolutely no guarantee that the sound quality will be
suitable. The church board would definitely be hearing a few complaints from members who had to sit in
a room across the street and couldn’t understand a thing that was said! The digital signal provided by the
Mongoose system solves this issue completely, delivering clear sound to the poor folks who slept too late
to get a church seat. Also, because it’s a simple tie-line system, the Mongoose provides the connection
without requiring a CobraNet network. The signal travels directly from an input RAD to the Mongoose to
an output RAD in the overflow room.
Following is the one-line drawing for this audio system:
