SECTION 2: UNDERSTANDING THE MONGOOSE SYSTEM
Rane understands the pain and expense of pulling and managing miles of analog cable throughout a large
audio installation, not to mention the potential for inferior sound quality. e advent and rapid adoption
of digital audio networking has almost ended this cabling and quality nightmare – but not quite. You
have probably utilized one or more of the networking solutions that exist today – for example, CobraNet,
Ethersound, and others. But, as discussed in the introduction, these solutions arent appropriate in all
situations. Because placing just a few channels on a large bandwidth network Bundle is inefficient and
expensive, you are probably still using analog cabling in low channel count applications.
Since you’re reading this manual, we can assume that you are seriously considering replacing all this
cabling with less expensive shielded CAT 5e cables and distributing the audio digitally via a RAD network.
Congratulations! You’ve made a wise choice. To help make this transition from analog to digital and from
older audio technology to new, this section provides a thorough explanation of the entire Mongoose
system – as well as suggestions for incorporating it into your larger audio system as efficiently as possible.
The Big Picture
