Digital Conversion at the Wall
Introduction
Mongoose Benefits
The purpose of Mongoose is to replace the analog mic
and line level portions of an audio system between the
equipment rack and remote spaces with digitized audio over
CAT 5 cable.
• RAD: Digital conversion at the wall or floor box. Not a
Cobranet device.
• Mongoose: Use with, or without, CobraNet.
• Sends and receives scattered digital audio efficiently.
• Greatly reduces troubleshooting.
• Greatly reduces the length of the analog transmission line.
• Status indicators at the point of remote signal entry.
• Change signal routing easily in software.
• Remove the hum and buzz problems of long runs.
• Greatly reduces conduit, labor, and wire cost in the RAD
network — especially the CobraNet run.
RADs
A Remote Audio Device (RAD) provides
analog to digital conversion at the wall (or
floor box). Several connection types and
colors are available.
MICROPHONE
RADs are not CobraNet devices, therefore
without CobraNet's rules and limitations.

RAD Network
Mongoose
The RAD network (blue) is a proprietary
four-channel (2x2) digital audio
bus that connects up to 8 RADs
to a single Mongoose.
The Mongoose routes audio between
RADs. It may operate on its own, or
connect to a CobraNet network.

CobraNet
Mongoose is capable of simultaneously sending two CobraNet
bundles and receiving two CobraNet bundles (16 x 16
channels). The Mongoose performs bundle aggregation
providing CobraNet users low-channel count capabilities of
individual RADs.
Versatility
Mongoose can send and receive digital audio on both the
RAD network and CobraNet. RAD network is an excellent
digital audio transport for non-CobraNet users. Multiple
Mongoose units can be networked to provide more channels.

This is the primary application for Mongoose. The
Mongoose is directly connected to any CobraNet device
port. The CAT 5 CobraNet run carries up to 32 (16 x 16)
channels. Relocating the A/D converters from the DSP to
the wall plate reduces or eliminates long analog runs.

Mongoose Math
CobraNet Users
Mongoose is self-funding in most applications. You save
more by using Mongoose. Significant savings are realized in
hardware, wire and conduit, and the installation of projects.
• Remove or reduce the analog I/O in the DSP.
• Reduce the number of DSP devices.
• A single CAT 5 transmitting CobraNet can replace up to
128 (64x64) channels.
• Pulling and terminating a single CAT 5 cable requires far
less labor than the 32 (or 64) twisted pairs it replaces.
A single Mongoose has the CobraNet capability of 32
channels. Double that to 64 in a multi-Mongoose system.
• In many applications conduit is not required for CAT 5.
Less conduit is required, because digitized audio does
not need to separate mic and line level. The conduit can
be smaller size because a single CAT 5 has the channel
capacity of a fist full of analog runs.
• Cost of terminating. Compare RJ45 crimps versus both
ends of 128 channels of XLRs.
• No time spent finding the hum and buzz culprits.
RADs and Mongoose may greatly reduce costs:
• RAD mic inputs provide 24V Phantom power.
• RADs are powered via the Mongoose.
• RADs are not CobraNet devices, for less rules: no
bundles, address, latency settings.
• CobraNet run <100 meters, RAD run <150 meters.
• Use the RAD network for low channel-count runs,
CobraNet for high channel-count runs.
• On-ramp or off-ramp for CobraNet (from mic to
loudspeaker).
• Aggregate channels to fill bundles.
Instant Diagnostics
Real time testing and status indicators address:
• Is this thing on? No question.
• RADs are their own cable and audio testers.
• Every aspect of RAD network hardware, wire,
terminations, and firmware.
• Monitor system integrity at the RAD, Mongoose, or
computer.
• Owner awareness of system status and solderless
replacement of RADs — No computer required.
• Contractor: verify the system is fully operational before
you leave the job site.
• Consultant: verify the system is fully operational before
you arrive at the job site.
Latency
RAD A/D converter (Input channel): 0.36ms.
RAD D/A converter (Output channel): 0.41ms.
Mongoose (RAD Network processing /
transport): <0.16ms.
CobraNet (selectable 1.3 ms, 2.6 ms, and 5.3
ms).
When calculating latency, know that RADs
usually relocate an A/D converter (from the
DSP to the wall) rather than add one. Therefore,
RADs normally do not add latency.
6
Unfamiliar with CobraNet?
The basic concept of CobraNet is the ability to send
multiple channels of digital audio from one device to
another using standard Ethernet networks. The basic
concept of Mongoose is to connect the scattered channels of
the RAD network to the multi-channel CobraNet network.
CobraNet isn’t scary. Here’s the short version. CobraNet
transmits individual channels of audio in Bundles. Bundles
contain up to 8 audio channels. Most CobraNet equipped
devices can send at least 2 bundles and receive at least 2
bundles (up to 16 x16 channels) though it is possible to
have more.
Suppose we have a Mongoose and want to send
(transmit) a Bundle of 8 audio channels to a DSP device.
Step 1. Pick a number that will be used to identify the
Bundle, say for example, Bundle number 500. Simply
enter 500 into Transmit Properties on the Mongoose
and into the Receive properties on the DSP.
Step 2. Set both the Mongoose and the DSP to the same
latency, i.e., 1.33 ms.

Programming
Mongoose Tracker Software
In the office
The Mongoose can be programmed in the office with
Mongoose Tracker Software. The on-site task is then limited
to system termination as spec'ed.
Mongoose Tracker is shipped on a CD with the
Mongoose product, and is also available free anytime at
www.rane.com/mongoose. It runs under Microsoft Windows®
XP or Vista.
The Mongoose Tracker allows you to easily and intuitively
configure and troubleshoot the RADs and Mongoose
devices in your system.
To communicate with your Mongoose, connect your
computer to a network switch or use a standard Ethernet
patch cable (or crossover cable) to connect directly.
Using Mongoose Tracker, you configure each Mongoose
RAD port with the RAD model to be connected to it. You
can also configure various settings for each RAD, for the
Mongoose itself, and for the CobraNet network.
Setting up the audio routing, using the matrix that
appears in Mongoose Tracker’s main window, makes it is
very easy to connect inputs to outputs.
Mongoose Tracker is also a valuable tool for
troubleshooting any issues that may arise. Although you
can determine a lot from the hardware status indicators, the
software provides more detail, allowing you to drill down
and pinpoint the problem with greater accuracy.
At the job site
On-site, Mongoose Tracker’s Match feature automatically
programs the RAD ports, based on detected devices.
Then simply route between the desired Input and Output
channels in the matrix, and add the CobraNet values if
applicable.
