ROUTING AUDIO VIA ETHERNET
RAVE™ is a revolutionary signal transport system that
allows you to route multiple channels of audio over
standard Ethernet hardware and cabling. A single RAVE
network can now replace hundreds of audio cables,
dramatically reducing installation time, effort and
cabling costs while improving routing flexibility and
audio performance. RAVE is the ideal audio transport
system for arenas, theatres, broadcast facilities, and
other applications requiring multiple channels routed
over long distances free of noise and hum.
Easy Routing of Multiple Audio Channels
What are the Benefits of RAVE?
Large sound systems often require routing dozens of audio channels over long distances to
multiple locations. Analog technology requires a separate line for each channel,leading to large
cables and conduits, and time-intensive installations.
• Reduce installation costs—replace up to 64 analog lines, conduit, isolation transformers,
Analog cabling can be a nightmare—prone to errors and subject to interference and noise. It’s
also time consuming to design and install, as well as difficult to re-route and reconfigure. Cable,
conduit, termination and labor costs can be the single largest expense of a system.
• Superior audio quality—up to 24-bit/48 kHz digital audio resolution system-wide,
RAVE is a digital audio transport system employing CobraNet™ technology licensed from Peak
Audio. This assures compatibility with all other CobraNet-licensed products—avoiding the
limitations imposed by closed-end, proprietary network audio systems. RAVE transports audio
signals over Fast Ethernet networking components in an uncompressed 48 kHz digital format in
resolutions of 16-, 20- or 24-bit. Using standard network hardware and physical media, a RAVE
system has a maximum capacity of 64 audio channels on a 100BASE-TX segment and the ability
to support hundreds of audio channels on a switched Ethernet LAN (Local Area Network).
• Greater flexibility—expand the system or re-route signals without rewiring
and distribution amplifiers with a single CAT-5 cable or fiber
immune to ground loops or EMI
Replace audio cable with a single CAT-5
network cable,or for longer distances
(>328 feet or 100m), with fiber optic cables.
A RAVE device can be configured by either the front panel switches or via software. You can
quickly design a RAVE network right out of the box by simple configuration via the front panel
switches. In software mode, RAVE offers an even greater array of configuration options—
accessible via SNMP (Simple Network Management Protocol). Such features include complex
audio mapping, audio channel duplication, device timing prioritization, and more. Once the
device is configured, parameters can be written into permanent memory.
RAVE can provide great economies over conventional wiring methods, yielding significant time
and cost savings in the reduction of cabling infrastructure. With six models available,it is easy to
interconnect a wide variety of analog and digital audio equipment. Finally,because it is Ethernet
based, RAVE easily supports system reconfiguration and expansion with off-the-shelf
networking components.

Building a RAVE Network
Building a RAVE Network
Standard Analog Approach
Each RAVE unit handles 16 audio channels—
in either analog or digital AES/EBU format,
depending on the model. More audio
channels can be added to a network using
additional RAVE units and inexpensive Fast
Ethernet hardware such as switches, repeaters,
and standard CAT-5 and fiber-optic cable
(with the use of media converters).
RAVE devices route the audio signals over a
standard Fast Ethernet network to the signal
processors (such as the DSP-3 devices) and
the amplifiers.

Switched Ethernet networks offer several advantages to audio system
designers that were not previously available—including the presence of nonaudio data via virtual networks, multiple network protocols, expanded
capacity for hundreds of audio channels, and redundant network links.
