The Beneﬁts of a Mongoose

To most eﬀectively design a system containing a RAD network, you need to understand its beneﬁts so you

can take full advantage of them. For example, when using RADs, not only can you place line-level audio

and a microphone within the same conduit, you can place it on the same cable!

Following is a brief discussion of how key aspects of an audio system are handled within a Mongoose

system versus a typical analog system.

Less Expensive Cabling and Conduit

e foremost advantage of the Mongoose system is its use of CAT 5 cables for audio distribution. We don’t

have to tell you the cost beneﬁts of using CAT 5 versus shielded audio cables and conduit. But bear with

us. Since we’re highlighting the beneﬁts of a Mongoose, we’ll expound a bit more on the cost savings. Not

only is CAT 5 cable much less expensive than shielded analog cable, use of CAT 5 cable eliminates the

need for conduit. In addition to that, a RAD can transmit up to four channels (two input, two output) over

one CAT 5 cable. To top things oﬀ, the RAD is also able to transmit power and a data signal – all on that

same CAT 5 cable. To provide all this functionality in an analog world would require pulling six times the

amount of cabling needed by the RAD network as well as the use of conduit to house all that cabling! So

not only is the medium itself less expensive, but the diﬀerence in time and labor costs is huge. As a matter

of fact, by using CAT 5 cables, it may be possible for some economies of scale – why not have the IT folks

pull and terminate your CAT 5 cable at the same time they pull the data wires for the building?

Simpler Cable Termination

Your installers will be happy to know that they can toss their soldering irons aside. Terminating connections

in the Mongoose system involves nothing more than the simple process of crimping CAT 5 cables. And

unlike soldering, the crimping process does not require electricity.

An added beneﬁt is the automatic testing that the Mongoose performs on each connection. When

the installer terminates and connects the CAT 5 cable to the RAD, the Mongoose automatically tests

the connection (assuming, of course, that the Mongoose is connected and powered on). e status of

the connection is immediately reported via the status lights on the RAD. If there’s a problem with the

connection, it can often be solved by simply re-crimping the cable – a much easier process than having to

re-solder a connection.

Better Sound Quality

Susceptibility to noise interference is much greater with analog than with digital transmission. Replacing

your analog channels with a RAD network immediately provides you with far superior sound quality –

especially if you’re transmitting the signal over substantial distances. In addition to eliminating noise

interference, the RAD’s transmitters and receivers have a high common mode range.

Digitizing the audio at the wall eliminates the mounting, expense, and trouble of isolation transformers

traditionally used in analog applications. Plus, passing low frequencies through analog isolation

transformers requires large cores and therefore more space. RADs save the space and pass those low

compromise.
