The Mongoose and its Tracker software work with Rane's Remotes Audio
Devices (RADs) and your CobraNet network to deliver digital audio to
the last mile of installations – between the equipment room/rack and
remote spaces. OK, it's not a mile, we lied: it's actually 100 meters
(328 feet to those in Liberia, Myanmar and the USA).
The Mongoose's 32-by-32 digital audio matrix router receives its first
16 audio channels from up to eight RADs via the eight rear panel 8P8C
(RJ-45) Remote Audio Device ports. The second 16 matrix input channels
come from two eight-channel CobraNet receive (Rx) Bundles via standard
CobraNet Primary and Secondary/backup ports. The 32 matrix router
outputs transmit 16 channels to eight RADs and 16 more channels to two
CobraNet transmit (Tx) Bundles.
family of RAD models connect to the Mongoose. Each converts analog
audio to or from 24-bit, 48 kHz digital audio. Standard CAT 5 cable and
termination transport four digital audio channels – two channels in
each direction – as well as power, ground and a communications channel
via Rane's proprietary RAD Network. Status indicators are at the RAD
signal entry points, at the front and back of the Mongoose, and in
Mongoose Tracker software.
can replace the analog mic and line level portions of an audio system
with digitized audio over regular CAT 5 cable. Mongoose can be used
with or without CobraNet.
Think about your last: auditorium, church, hotel, theater, stadium,
convention center, campus, bar, restaurant, club. Rane's Mongoose and
RADs solve problems you likely encountered if you ran analog audio
between remote rooms and equipment racks.
Problem 1: Transmit & receive a small number of audio channels (2-6) to multiple, scattered locations.
Solution 1: Mongoose & Remote Audio Devices (RADs).
Problem 2: Conduit is expensive & multiple independent runs are needed for: mic, line, speaker, computer data, AC power...
2: Mongoose & RADs' digital CAT 5 solution eliminates or greatly
reduces mic & line conduit costs, labor, troubleshooting... Some
jobs may permit using the computer/data conduit, cable, labor and
Problem 3: Analog termination
requires either stripping & screwing down each wire (for
Euroblocks) or soldering each wire and assembling the connector (XLR,
TRS or RCA).
Solution 3: RAD Network CAT 5 cables are quick and easy to terminate using standard 8P8C (RJ-45) connectors.
Problem 4: Analog twisted-pair (mic/line) cable is costly & requires 1 cable per channel.
4: RADs digitizes audio at each wall location, transporting 4 channels
(2 in each direction) on a single, less expensive CAT 5 cable.
5: Analog cable & devices (MP3/CD players, satellite receivers,
laptops) are prone to ground loops, electromagnetic interference (EMI),
hum, buzz, noise...
Solution 5: RAD Network audio is uncompressed, 24-bit, 48 kHz digital, run over differentially balanced CAT 5.
6: Long analog cables beyond 12 feet (3.6 meters) require isolation
transformers. And if you require low frequencies, large transformers
Solution 6: RADs support a 492 foot
(150 meter) long digital RAD Network that provides 45 volt common mode
rejection without isolation transformers.
Problem 7: Testing analog audio wall connections is lots of work for installers.
Solution 7: RADs'indicators immediately self-test CAT 5 connectivity.
Problem 8: Analog wiring mistakes & broken cables in distant rooms are difficult to troubleshoot.
8: Both ends of RAD Network cables & the Mongoose Tracker software
indicate and inform installers about any and all wiring mishaps.
Problem 9: Fork lifts that meet XLR wall plates at high velocities equals a service call.
Solution 9: Maintenance staff can order and replace RADs without a contractor or a PC.
Problem 10: There are no signal or overload indicators, or the cable's good indicators on analog XLR plates.
Problem 11: Re-routing analog audio via patch bays is troublesome & problematic.
Solution 10: RADs have all these – and they dim with the light level in the room.
11: Mongoose adds matrix routing where it was previously unaffordable
(e.g., tie line applications), plus cost-effectively route disparately
scattered audio sources/destinations to and from CobraNet.
