Multi-Channel Digital Audio Transfer Systems

Multi-Channel Digital Audio Transfer Systems

•REAC, based on the Ethernet 100BASE-TX protocol,
transfers signals using Cat5e cable.

•Durable and reliable connector made by Neutrik

•Up to 40 channels of 24bit/96kHz audio plus MIDI and
remote control data can be transferred in one cable.

Roland’s original Ethernet technology

REAC (Roland Ethernet Audio Communication) is newly designed technology
for digital audio transfer by Roland. The REAC spec provides a high quality and
safe, redundant digital audio transfer system that can be easily installed or inte­grated for any audio snake application. REAC is a “plug and play” system that
is easy to configure and requires no complex setup or computer operation. Plug
in your mics, plug in the Ethernet cable and you’re ready to go!

The superior quality and reliability of RSS Digital Snakes is made possible by coupling high quality preamps with
Roland’s REAC digital transmission technology. RSS Digital Snake systems are immune to the hums, buzzes
and general impedance and capacitive losses that plague analog snakes. By having the mic preamps close to
their source and by avoiding the transmission losses of long runs of analog cables, your audio has a chance
to sound its best throughout your whole system. The system provides superior clear sound, great intelligibility
with minimum latency and the freedom to easily split or extend your source audio. Digital Snakes ar e the ne xt
generation of audio quality for concerts, corporate events, houses of worship and any kind of audio installation.

High Quality Pre-amps on each input channel

In an analog system, low-level microphone signals are boosted using a mic
preamp only after the long, arduous journey down the analog snake. For this
reason it’s difficult to avoid degradation and cross talk. The digital snake is
equipped with high quality and remote controllable pre-amps that boost the
input gain very close to the source, where the highest quality signal is found.
This ensures that your audio will sound its best. And of course once the signal
is in digital form, it is immune to analog cabling losses. The pre-amp has
been specially designed for live audio applications and is made of high quality
components carefully selected by Roland’s engineers.

■ Latency of digital transfer (one way)

* 0.375 ms is the REAC protocol latency. The A/D and D/A

conversions add a bit more for a total latency of less than

1.2ms, which is very low and well within the acceptable
range for all live audio applications.

Simple and low cost installation with Cat5e cabling

REAC brings another revolution to audio installations by eliminating the need
to use thick, heavy and hard to handle analog multi-pair cables by transmitting
audio using light, slim and easy to handle Cat5e cable. On one very thin Ethernet
cable, REAC can transfer 40 channels of high quality 24bit/96kHz audio signal
plus MIDI and remote control signals. Since the cable used for REAC transfer is
ordinary Ethernet cable, the low cost and easy availability of the cable is a big
advantage compared with using analog cable. From temporary installations in
outdoor concerts to permanent installations in arenas or halls, REAC provides
the benefit of light weight, inexpensive and easy to install cable.

Super low latency digital transmission

Degradation of the audio signal is minimal in any digital transfer system.
However, musicians, performers or even audiences may suffer from the
excessive latency of other digital transfer systems. REAC eliminates these
digital audio transmission problems with its super low latency. Even when
transmitting 40 channels at 24bit/96kHz/Linear, REAC’s latency is only

0.375ms*. This very low latency makes any RSS Digital Snake system perfect
for all audio installations, especially in-ear monitoring systems.

In the analog domain, it is impossible to avoid signal degradation during long
distance audio transfer at concerts or events in large halls or arenas. Digital
transfer of REAC provides extremely flat and pure audio transfer for the whole
frequency bandwidth. Furthermore, additional audio benefits occur because the
source signal is transferred after boosting the gain using the high quality and
remote controllable mic pre-amps.

High quality and low noise digital transfer

Minimize a signal’s damage due to “noise pollution”

Hums and buzzes from external noise sources can often be a problem for
analog snake installation. It can be difficult to know where potential noise
sources might be before installing a snake. Solving subsequent noise problems
requires alot of experience and time. REAC provides an effective solution to
these installation problems. Technically, the risk of noise pollution such as the
induction of hums and buzzes into a digital snake is much lower than in an
analog snake, and cross talk is minimal or non existent. This provides almost
complete routing freedom for your cable installations.

S-4000S/H

Ordinary Mic cable (100m)

Remote Control by computers

A computer can be connected to the REMOTE terminals (RS-232C) of any
digital snake end. Once the S-4000RCS software* is installed, up to 160
channels of a snake system can be remote controlled from your computer
using up to 4 RS-232c ports.

* S-4000RCS software is free and downloadable from www.rssamerica.com.

Limitless splitting of all input sources

The RSS Digital Snake systems are designed to provide splits of source audio
using standard Ethernet hardware. Using a standard switching hub, you can
send source audio to multiple recording consoles, a monitor position, broadcast
location and more. No signal degradation will occur from the source’s master
output to the recording or any other split output.

Very long distance snake systems can be designed using

an S-OPT REAC Optical converter

The S-OPT is a REAC optical converter that converts RSS Digital Snake
System REAC signals to and from optical signals for long distance digital audio
transmission. By using the REAC optical converter and optical cables (sold
separately), the REAC transmission distance can be extended to a maximum of
2 kilometers (1.2 miles).

40 Channels of Digital Recording

The SONAR REAC Recording System when used in conjunction with the RSS Digital Snakes
provides the most comprehensive live recording, mixing, mastering and delivery product
available. Capture up to 40 channels of audio from your Digital Snake/V-Mixing System
directly into SONAR all via a simple Cat5e connected to the network port on your PC.

“ e fact that there is no noise when I turn the snake on is
a vast improvement over previous years. No hums, buzzes
or clicks, which means one less place to look when I am
trouble shooting,”

Jon Laterza, Freelance Audio Engineer,
Lincoln Center Out of Doors Festival, NY

“Even though sound quality was an important factor in
selecting the RSS Snake, the  exibility of the system was
the key selling point. We’re thrilled to have invested at the
beginning to have a system to grow with us for years.”

Rick Charleton
Audio Engineer, Grace Lutheran Church

“ e sonic quality and clarity of the digital snake
is awesome, I feel and hear the dynamics of the
sound clearer than any analog snake. Plus it’s
extremely easy to move for touring.”

Bernie Sandor
Springfever Productions, Toronto, Canada

“What can I say… the Digital Snake just
worked  awlessly and sounded great!”

Jefferey Bruton
GMB Technical (KPLU), Seattle, WA

“ e 64x16 system is perfect; it’s very  exible, so
we can con gure the I/O’s as needed for ballroom
events, our live concert locations and any special
audio need.”

Gino Mulcahy
Mohegan Sun Casino

Never in my decades of audio experience had I
heard such a vast improvement in sound quality.

Art Yeap, Designer/Integrator
Co-Owner of the Novo Group Inc.

“We tested the RSS snake against a 300 foot copper snake.
 e Cat5 audio was much smoother overall. It has much
greater clarity at the top end. We did a blind listening test
and chose the RSS Digital Snake every time!”

Jon Garber
FOH Engineer, Rascal Flatts
