• Before using this unit, make sure to read the
instructions below, and the Owner's Manual.
• Connect mains plug of this model to a mains
socket outlet with a protective earthing
connection.
A
• Do not open or perform any internal modifications on the unit.
• Do not attempt to repair the unit, or replace parts
within it (except when this manual provides
specific instructions directing you to do so). Refer
all servicing to your retailer, the nearest Roland
Service Center, or an authorized Roland
distributor, as listed on the "Information" page.
• Never use or store the unit in places that are:
• Subject to temperature extremes (e.g., direct
sunlight in an enclosed vehicle, near a heating
duct, on top of heat-generating equipment); or
are
• Damp (e.g., baths, washrooms, on wet floors);
or are
• Humid; or are
• Exposed to rain; or are
• Dusty; or are
• Subject to high levels of vibration.
A
• The unit should be connected to a power supply
only of the type described in the operating
instructions, or as marked on the rear side of unit.
E
• Use only the attached power-supply cord. Also,
the supplied power cord must not be used with
any other device.
• Do not excessively twist or bend the power cord,
nor place heavy objects on it. Doing so can
damage the cord, producing severed elements
and short circuits. Damaged cords are fire and
shock hazards!
• This unit, either alone or in combination with an
amplifier and headphones or speakers, may be
capable of producing sound levels that could
cause permanent hearing loss. Do not operate for
a long period of time at a high volume level, or at
a level that is uncomfortable. If you experience
any hearing loss or ringing in the ears, you should
immediately stop using the unit, and consult an
audiologist.

Using the Unit Safely
A
• Immediately turn the power off, remove the
power cord from the outlet, and request servicing
by your retailer, the nearest Roland Service
Center, or an authorized Roland distributor, as
listed on the "Information" page when:
• The power-supply cord, or the plug has been
damaged; or
• If smoke or unusual odor occurs
• Objects have fallen into, or liquid has been
spilled onto the unit; or
• The unit has been exposed to rain (or
otherwise has become wet); or
• The unit does not appear to operate normally
or exhibits a marked change in performance.
• In households with small children, an adult
should provide supervision until the child is
capable of following all the rules essential for the
safe operation of the unit.
• Protect the unit from strong impact.
(Do not drop it!)
• Do not force the unit's power-supply cord to share
an outlet with an unreasonable number of other
devices. Be especially careful when using
extension cords---the total power used by all
devices you have connected to the extension
cord's outlet must never exceed the power rating
(watts/amperes) for the extension cord. Excessive
loads can cause the insulation on the cord to heat
up and eventually melt through.
• Before using the unit in a foreign country, consult
with your retailer, the nearest Roland Service
Center, or an authorized Roland distributor, as
listed on the "Information" page.
A
• The unit should be located so that its location or
position does not interfere with its proper ventilation.
B
• Always grasp only the plug on the power-supply
cord when plugging into, or unplugging from, an
outlet or this unit.
A
• At regular intervals, you should unplug the
power plug and clean it by using a dry cloth to
wipe all dust and other accumulations away from
its prongs. Also, disconnect the power plug from
the power outlet whenever the unit is to remain
unused for an extended period of time. Any
accumulation of dust between the power plug
and the power outlet can result in poor insulation
and lead to fire.
• Try to prevent cords and cables from becoming
entangled. Also, all cords and cables should be
placed so they are out of the reach of children.
• Never climb on top of, nor place heavy objects on
the unit.
B
• Never handle the power cord or its plugs with
wet hands when plugging into, or unplugging
from, an outlet or this unit.
A
• Before moving the unit, disconnect the power
plug from the outlet, and pull out all cords from
external devices.
• Before cleaning the unit, turn off the power and
unplug the power cord from the outlet.
• Do not put anything that contains water (e.g.,
flower vases) on this unit. Also, avoid the use of
insecticides, perfumes, alcohol, nail polish, spray
cans, etc., near the unit. Swiftly wipe away any
liquid that spills on the unit using a dry, soft
cloth.
A
• Whenever you suspect the possibility of lightning
in your area, pull the plug on the power cord out
of the outlet.
B
• Keep the included ferrite cores and REAC
connector covers in a safe place out of children's
reach, so there is no chance of them being
swallowed accidentally.
C
• Keep any screws for the connector guard you may
remove and the included screws for the connector
guard in a safe place out of children's reach, so
there is no chance of them being swallowed
accidentally.

Using the Unit Safely
• Always turn the phantom power off when
connecting any device that does not require +48 V
phantom power. You risk causing damage if you
mistakenly supply phantom power to dynamic
microphones, audio playback devices, or other
devices that donʼt require such power. Be sure to
check the specifications of any microphone or
other device you intend to use by referring to the
documentation that came with it.
(The S-4000S phantom power specification:
+48 V DC, 14 mA Max.)

Important Notes
In addition to the items listed under IMPORTANT
SAFETY INSTRUCTIONS (Page 2) and USING THE
UNIT SAFELY (Page 3), please read and observe the
following:
•
Noise may be produced if wireless communications
devices, such as cell phones, are operated in the
vicinity of this unit. Such noise could occur when
receiving or initiating a call, or while conversing.
Should you experience such problems, you should
relocate such wireless devices so they are at a
greater distance from this unit, or switch them off.
•
When moved from one location to another where
the temperature and/or humidity is very different,
water droplets (condensation) may form inside
the unit. Damage or malfunction may result if you
attempt to use the unit in this condition. Therefore,
before using the unit, you must allow it to stand for
several hours, until the condensation has completely
evaporated.
Power Supply
•
Do not connect this unit to same electrical outlet
that is being used by an electrical appliance that
is controlled by an inverter (such as a refrigerator,
washing machine, microwave oven, or air
conditioner), or that contains a motor. Depending
on the way in which the electrical appliance is
used, power supply noise may cause this unit to
malfunction or may produce audible noise. If it
is not practical to use a separate electrical outlet,
connect a power supply noise filter between this
unit and the electrical outlet.
•
Before connecting this unit to other devices, turn
off the power to all units. This will help prevent
malfunctions and/or damage to speakers or other
devices.
•
Although the LEDs are switched off when the
POWER switch is switched off, this does not mean
that the unit has been completely disconnected
from the source of power. If you need to turn off the
power completely, first turn off the POWER switch,
then unplug the power cord from the power outlet.
For this reason, the outlet into which you choose to
connect the power cord’s plug should be one that
is within easy reach and readily accessible.
Maintenance
•
For everyday cleaning wipe the unit with a soft,
dry cloth or one that has been slightly dampened
with water. To remove stubborn dirt, use a cloth
impregnated with a mild, non-abrasive detergent.
Afterwards, be sure to wipe the unit thoroughly
with a soft, dry cloth.
•
Never use benzine, thinners, alcohol or solvents of
any kind, to avoid the possibility of discoloration
and/or deformation.
Additional Precautions
•
Use a reasonable amount of care when using the
unit’s buttons, sliders, or other controls; and when
using its jacks and connectors. Rough handling can
lead to malfunctions.
•
When connecting / disconnecting all cables, grasp
the connector itself—never pull on the cable. This
way, you will avoid causing shorts, or damage to
the cable’s internal elements.
•
A small amount of heat will radiate from the unit
during normal operation.
•
To avoid disturbing your neighbors, try to keep the
unit’s volume at reasonable levels (especially when
it is late at night).
Placement
•
Using the unit near power amplifiers (or other
equipment containing large power transformers)
may induce hum. To alleviate the problem, change
the orientation of this unit; or move it farther away
from the source of interference.
•
This device may interfere with radio and television
reception. Do not use this device in the vicinity of
such receivers.

1—Introduction
Conventions Used in the Manual
Names
The S-4000 Digital Snake System is comprised of three primary components:
•
S-4000S 40 CH I/O Modular Rack
•
S-4000H 32x8 FOH Unit
•
S-4000R Remote Controller
Throughout the text, the individual components’ names are often shortened, and referred to simply as
“S-4000S,” “S-4000H,” and “S-4000R.” When a procedure or description refers to the entire system,
the name “S-4000 System” is used.
Additionally, the names of buttons, knobs, and connectors are shown exactly as they appear on the
system components. As a result, these names are shown completely in capital letters. For example, the
button labeled “LOCK” will appear in the manual as the LOCK button, or simply LOCK, as in “Press
LOCK.”
One button on the S-4000R serves a dual purpose. The button’s name indicates both of its functions:
CLIP CLEAR•ENTER.
Usage Conventions
The purpose of the S-4000 System is to function as an audio “snake”—a device used to transfer
multiple audio signals from one place to another, usually over a long distance. Since the S-4000
System transfers signals as digital data—the system’s primary benefit—it’s called a “digital snake.”
In most cases, audio snakes are used in sound reinforcement applications that involve a musical
performance, a theatre presentation, or an orator (or orators). In such applications, the primary source
of the audio is at a “stage” area, and that audio is sent via the snake to a “mixing” position (also
referred to as the “front of house” or FOH position).
Of course, there are many other usage applications for an audio snake, such as transferring audio
to a recording setup, a broadcast feed, or any other application where multiple audio signals are
transferred and managed.
Occasionally, the manual refers to a physical location for the system’s components as the “stage,”
“mixing,” or “front of house” location. These terms are used only for the sake of brevity or to illustrate
the signal flow of the system in terms understood by a typical audio engineer. However, they are not
meant to imply that the system is unsuited for a particular alternate application. The S-4000 System
will function just as well in any installation where an audio snake is required.

S-4000 System Overview
Concept
The S-4000 System brings the digital revolution to the world of audio snakes. Using computer
networking technology, the system allows you to transfer 40 channels of high-quality audio over an
extremely long distance on a single lightweight cable. The digital advantage also brings with it easy
installation, low cost, portability, and pain-free expansion.
The Old School...
Traditional audio snakes transfer signals as analog audio. They consist of a large diameter cable
containing multiple wires—one for each channel—that carry the audio signals from one location to
the other. Though they get the job done, analog snakes are bulky, heavy, and often very expensive.
On top of that, analog signals traveling through hundreds of feet of cable always have some degree of
high-frequency loss and overall degradation due to cable capacitance, inductance, and resistance.
...Meets the New Generation
The fundamental benefit of the digital snake is that it eliminates long analog audio signal transfers and
the signal degradation and noise interference that always comes along with them. This is accomplished
by converting audio signals to digital data near the source, allowing them to be transferred hundreds
of feet with absolutely no loss in sound quality. Additionally, since the multiple signals are transferred
over a single lightweight cable, the enormous bulk of the analog snake’s multichannel cable is also
eliminated.

5—S-4000 System Overview
Things to Know
About
At the heart of the S-4000 System is the REAC (Roland Ethernet Audio Communication) interface. This
proprietary protocol is based on the Ethernet technology that’s used in computer networks, and allows
for the transfer of up to 40 channels of digital audio over a single Cat5e Ethernet cable.
REAC features and benefits:
•
40 channels of digital audio transfer at a 24-bit/96 kHz sampling rate
•
Cable length up to 100 meters (330 feet)
•
Cable length extension using Ethernet switching hubs
•
Easy device splits using Ethernet switching hubs
•
Extremely low device-to-device transmission latency (375 microseconds)
•
Hot-swappable connection
•
MIDI pass-through communication between REAC devices
Understanding Cables and Connections
Hooking REAC devices together is extremely easy, as connections are made using Cat5e (short for
“Enhanced Category 5”) Ethernet cable. This cable is a standard in the computer connection world—in
fact, you may be using an Ethernet cable in your home or office right now to connect your computer
to a high-speed modem, a printer, or a network. This lightweight cable uses RJ45 plugs, which are very
similar to standard telephone connectors.
Cat5e Ethernet Cable Types
There are two different types of Cat5e Ethernet cables that you can use with the
S-4000 System. Though the cables look the same on the outside, the RJ45 plugs are wired in different
ways. With a:
•
crossover cable—some
e
of the wires inside the cable are “crossed over” at each RJ45 plug. As a
result, the two RJ45 plugs on each end of a single cable are wired differently.
•
straight-through cable—the
e
wires inside the cable are connected to each RJ45 plug in the same
arrangement (each plug is wired the same).
It’s important to understand and recognize the difference between these cable types, because they
can’t always be used interchangeably when making REAC connections. In Chapters 6 and 7, we’ll
discuss making REAC connections and let you know what cable type to use in particular situations. For
now, here are some basic rules to know when connecting REAC devices together:
34
•
A crossover cable mustt be used whenever one device’s REAC port is connected directly to another
device’s REAC port with a single Ethernet cable. (The connection of REAC devices directly to each
other is referred to throughout this manual as a “REAC-to-REAC” connection.)
•
Two straight-through cables coupled with an Ethernet crossover adaptor can be used for a REACto-REAC connection.
S-4000 Digital Snake Owner’s Manual
5—S-4000 System Overview
•
Straight-through cables should be used when an Ethernet switching hub is integrated into the
system for cable length extension or split applications. (We’ll discuss switching hubs a little
later.)
Ethernet connection standards recommend using straight-through cables to connect devices
to the ports on a switching hub, and crossover cables when connecting hub-to-hub. However,
some switching hubs provide ports that allow the use of either crossover or straight-through
cables—the port will detect the type of cable that’s connected and adjust the signal transfer
accordingly. Consult the switching hub’s documentation to determine which type of cables you
should use with it.
See Appendix B: Connector Information for Cat5e crossover and straight-through cable wiring
diagrams.
Ethernet Connectors
As mentioned previously, Cat5e Ethernet cables use RJ45 plugs. Each REAC device provides an RJ45
receptacle for each of its REAC ports (MAIN and BACKUP).
,{xÊ«Õ}
, Ê,{xÊÀiVi«Ì>Vi
Though the standard RJ45 connection is very reliable, in high-traffic installations you may want to
protect the connection between the RJ45 plug and its receptacle. To this end, REAC RJ45 receptacles
utilize rugged Neutrik® EtherCon® connectors. When used with RJ45 plugs housed in EtherCon
connectors, this provides a robust latching connection similar to that provided by an XLR connector.
Neutrik offers EtherCon connectors for the fabrication of new cables (models NE8MC-1 and NE8MC1-B), and EtherCon connectors that can be added to a pre-made Ethernet cable (models NE8MC and
NE8MC-B).
A REAC port’s RJ45 receptacle can accept either a regular RJ45 plug or one housed in an
EtherCon connector.

5—S-4000 System Overview
About Ethernet Switching Hubs
An Ethernet switching hub—sometimes referred to simply as a “switch”—is an interface that allows
multiple devices (called “nodes” in Ethernet lingo) to communicate with each other in an Ethernet
network. The switching hub has multiple ports with RJ45 receptacles, and each network device
is connected to one of these ports. When one of the network devices transmits information, the
switching hub’s internal electronics makes sure this information is passed on to the intended receiving
device.
Since REAC is based on Ethernet technology, switching hubs can be used to extend the functionality
of the REAC system. Use a switching hub when:
•
you need to extend the REAC cable length—The maximum length for a single REAC cable is 100
meters. However, if you need to extend the cable length, you can use two straight-through
cables with a switching hub in-line to “refresh” the REAC signal and extend it another 100
meters. (Up to four switching hubs can be used for a maximum cable length extension of 500
meters.) See Chapter 6 for more information.
•
you want to split input audio—from
o
a “Master” REAC device to one or more “Split” REAC devices.
See Chapter 7 for information on splitting audio to multiple destinations.

REAC device modes—including “Master” and “Split”—are discussed starting on Page 49.
To be used in a REAC system, an Ethernet switching hub must meet the following requirements:
•
1000BASE-T transmission speed (IEEE802.3ab, Gigabit Ethernet)
•
Support for 100BASE-TX devices (IEEE802.3u, Fast Ethernet)
•
Bidirectional (full-duplex) communication
Connect REAC devices only to switching hub ports that support 100BASE-TX.

S-4000 Digital Snake Owner’s Manual
5—S-4000 System Overview
The transmission protocol for REAC is based on 100BASE-TX (Fast Ethernet). To transfer 40
channels of digital audio, REAC uses the full bandwidth of this protocol. However, some 100BASETX switching hubs cannot handle this amount of data traffic. Gigabit Ethernet switching hubs
can handle a larger amount of data traffic, so we recommend them for use with REAC devices
(just be sure that the Gigabit switching hub you use supports 100BASE-TX devices).
Consult the switching hub’s documentation for information on its proper use.
Built-in Redundant Connections
In case of an Ethernet cable failure, each REAC device provides two REAC ports—MAIN and BACKUP.
The MAIN port is used for the primary REAC connection, while the BACKUP port provides a redundant
backup. Should the primary connection fail, the backup connection will automatically take over. (Note:
Separate Ethernet cables are used for the MAIN and BACKUP connections.)
A/D-D/A Conversion and Signal Optimization
Before an analog audio signal can be transmitted through REAC, it must first be converted to digital
data. Once in digital form, the audio is sent down the Ethernet cable to the receiving REAC device.
When it arrives there, the signal is converted back to analog for connection to an audio device such
as an analog mixing console. This process of turning analog audio into digital data and back again is
called analog-to-digitall (A/D) and digital-to-analog
g (D/A) conversion.
The S-4000S and S-4000H units employ extremely high-quality 24-bit/96 kHz A/D and D/A converters
on all audio inputs and outputs for the very best possible sound quality.
Additionally, the S-4000S provides variable gain preamps on each of its 32 audio inputs. This allows
for signal optimization at the source, resulting in the highest A/D conversion quality.
RS-232C Serial Interface
The S-4000S and S-4000H feature REMOTE jacks that support the RS-232C serial interface protocol.
RS-232C is a standard communications interface found in computers.
The S-4000 System can be controlled from a remote device utilizing RS-232C, such as the included
S-4000R Remote Controller or a personal computer running the S-4000 Remote Control Software.
If RS-232C devices are connected to the REMOTE jacks on both the S-4000S and S-4000H, the
system can be controlled from either device (though only one remote device can control the
system at any given time).

5—S-4000 System Overview
Optional Redundant Power Supply
The S-4000S and S-4000H units each provide rear panel EXT. POWER DC INPUT jacks for connecting an
optional S-240P External Power Supply Unit. The S-240P provides backup power—and uninterrupted
audio—should a unit’s internal power supply fail. As with the redundant REAC connection, this
provides an important “safety net” in critical sound reinforcement situations.
To provide redundant power for the entire system, use a separate S-240P for each S-4000S/
S-4000H unit.
The System Components: A Closer Look
S-4000S 40 Channel I/O Modular Rack
The S-4000S is the stage connection interface for the S-4000 System. Its modular design supports 40
channels of audio input and output (I/O). As standard, it comes in a 32x8 configuration—32 audio
inputs and 8 audio outputs.
The “modular” aspect of the S-4000S is in its connectivity. The unit’s chassis provides 12 slots for
various RSS modules. The standard 32x8 configuration includes:
•
eight SI-AD4 Input Modules—Each
s
SI-AD4 contains four balanced audio inputs with variable gain
preamps, phantom power, and pad. Additionally, each input is equipped with a 24-bit/96 kHz
A/D converter.
•
two SO-DA4 Output Modules—Each
s
SO-DA4 contains four balanced line level audio outputs.
Additionally, each output is equipped with a 24-bit/96 kHz D/A converter.
•
one S-REAC2 Module—This
e
module provides two REAC connection ports—one for the main REAC
connection, the other for a redundant backup.
•
one S-BP Blank Panel—This
l
panel covers the final unused module slot. An optional RSS module
can be installed here.
RSS modules are not user-installable. They must be installed at the factory or by an RSS
Authorized Service Center.
About the Remote Controlled Preamps
Each input on the SI-AD4 modules employ a newly-developed XR-1 variable gain preamp. Designed
for warm and accurate sound reproduction, the XR-1 accepts input signal levels from -65 to +10 dBu.
Additionally, it provides an enormous amount of headroom before distortion—an incredible +28 dBu
maximum input level. Each preamp’s gain is controlled remotely from the S-4000R or S-4000 RCS,
allowing you to optimize signal levels right at the connection interface.
If you’re connecting the S-4000 System to an analog mixing console, you may be wondering why you
need adjustable gain at the S-4000S’s inputs. After all, you have gain adjustment at the console inputs,
right? Well, there are a few very good reasons to adjust the signal level at the S-4000S inputs:
38
S-4000 Digital Snake Owner’s Manual
5—S-4000 System Overview
•
Better analog signal quality—By
y
adjusting the input gain so close to the source, the analog signal
travels through less analog cabling before the signal level is optimized. Shorter analog cabling
means less possibility of noise and signal deterioration.
•
Better digital signal quality—A/D
y
converters take “snapshots” of the analog audio during the
digital conversion process. By optimizing the signal level before the A/D converter, a much
higher resolution snapshot can be taken—and higher resolution means better signal quality.
•
Memory presets add digital mixer features to the analog mixer—One
r
of the big advantages of a
digital mixer is the ability to store and recall frequently used setups. By taking advantage of the
10 memory presets in the S-4000R—or 100 presets using the S-4000 RCS—you can bring some
digital functionality to your analog mixer. (More on the S-4000R in a little bit.)
S-4000H 32x8 FOH Unit
The S-4000H is the front-of-house (FOH) connection interface for the S-4000 System. As such, its I/O
configuration is the opposite of the S-4000S—8 audio inputs and 32 audio outputs.
As it name suggests, the S-4000H FOH Unit’s main application is near the FOH mixing
console. However, the S-4000H can be used anywhere you need to receive stage audio from
the S-4000S—at a monitor console, a multi-channel recording device, a broadcast feed, etc.
Additionally, multiple S-4000H units can be used for split destinations when connected to the
system via an Ethernet switching hub. See Chapter 7 for details.
About the S-4000H’s Audio I/O
The S-4000H’s audio I/O is provided on standard DB-25 connectors. Each connector supports eight
channels of audio.
•
One input connector—provides
r
eight channels of balanced line level audio. Each input channel is
equipped with a 24-bit/96 kHz A/D converter.
•
Four output connectors—provide
s
eight channels of balanced line level audio per connector. Each
output channel is equipped with a 24-bit/96 kHz D/A converter.
By providing audio on DB-25 connectors, breakout cables can be easily connected for a quick and
clean setup. RSS offers the following optional breakout cables:
•
SC-A0805DM—4.5
M
meter male breakout cable to connect S-4000H outputs to audio destinations
(DB-25 connector to eight male XLR connectors).
•
SC-A0805DF—4.5
F
meter female breakout cable to connect audio sources to S-4000H inputs
(eight female XLR connectors to DB-25 connector).
If desired, you can purchase third-party breakout cables or fabricate your own to suit your requirements.
See Appendix B: Connector Information for information about the S-4000H’s DB-25 connectors.

5—S-4000 System Overview
Why Doesn’t the S-4000H Have Remote Controlled Preamps?
Since the S-4000H is designed to be used near the mixing location, its audio inputs will most often
receive line level audio from the mixing console (e.g., to feed amplifiers at the stage position). In this
application, variable gain preamps are unnecessary, since the audio level can be easily adjusted at the
source. As such, the S-4000H’s inputs are fixed at line level (+4 dBu).
The signal level at the S-4000H inputs can be monitored from the S-4000R or the S-4000 RCS.
S-4000R Remote Controller
The S-4000R functions as a remote controller for the S-4000 System. It can be connected to either the
S-4000S or S-4000H unit, whichever is most convenient for you.
•
S-4000S input channel control—The
l
S-4000R provides control over the S-4000S’s input channels.
This includes preamp gain adjustment, phantom power and pad on/off status, and channel
linking.
•
Input level monitoring—An
g
eight-segment LED meter allows for precise preamp gain adjustment
of the S-4000S’s input channels. Additionally, the meter can be used to view signal levels from
the S-4000H’s audio inputs.
•
Signal status—The
s
S-4000R provides signal status indicators for all of the S-4000 System’s 40
input channels.
•
Clip indicators—The
s
S-4000R provides channel clip indicators for all of the S-4000 System’s 40
input channels.
•
Memory presets—10
s
memory presets allow you to store and recall frequently used S-4000S input
channel setups.
Computer Control
All functions that can be controlled from the S-4000R can also be controlled from a personal computer
equipped with an RS-232C port(s), and running the S-4000 Remote Control Software (S-4000 RCS).
Up to four S-4000 Systems can be controlled at once.
The S-4000 RCS is a free download from www.roland.com.

Installation Notes
S-4000S and S-4000H
The S-4000S and S-4000H can be used in a free standing configuration, or rack-mounted using the
installed rack-mount brackets.
Whatever method you choose, be sure to provide adequate air flow around the units, and be sure
not to block the intake and exhaust vents. Failure to do so will result in the units overheating, causing
automatic shutdown and possible damage.
For the location of the intake and exhaust vents, see Chapter 4, Panel Descriptions.
Using the AC Cord Clamp
The S-4000 and S-4000H units have AC cord clamps to prevent the cord from being pulled out
accidentally.
Recessed Rack-Mounting
If desired, the rack-mount brackets on the S-4000S and S-4000H units can be reinstalled so that the
units’ face plates are recessed when mounted in a rack. This can be useful for protecting the front panel
connections in high-traffic installations, as the connectors plugged into the various inputs and outputs
will not protrude from the face of the rack.
Reinstall the rack-mount brackets only in the configurations shown. Attempting to reinstall
the rack-mount brackets in a different configuration will not provide enough support for rackmounting, and may result in damage to the units.

Setting the REAC Mode
The S-4000S and S-4000H each feature a REAC MODE switch.
This switch sets the REAC behavior of each device, and determines
how audio is transferred throughout the system. Each unit’s
REAC MODE switch must be set properly for correct system
operation.
The REAC MODE switch has three different settings:
•
•
•
M—configures
—
the unit as a Master REAC device. A Master REAC device can:
•
send audio signals to Slave and Split REAC devices.
•
receive audio signals from a Slave REAC device.
S—configures
—
the unit as a Slave REAC device. A Slave REAC device can:
•
receive audio signals from a Master REAC device.
•
send audio signals to a Master REAC device.
SP—configures
—
the unit as a Split REAC device. A Split REAC device can:
•
receive audio signals from a Master REAC device (a Split device cannott send audio
signals).
When setting the REAC MODE switches, here are the most important rules you need to know:
•
There must be—and can only be—one Master REAC device in a system.
•
There must be—and can only be—one Slave REAC device in a system.
•
There can be many Split REAC devices in a system.
•
In most circumstances, it’s best to make the main stage connection unit the Master REAC device
and the FOH unit the Slave REAC device. (This configuration allows you to split the stage audio
to multiple destinations—see Chapter 7.)
The only time you need to set a unit as a Split REAC device is when you’ve expanded the system with
one or more additional S-4000H units connected via an Ethernet switching hub. In these cases, the
additional units are set as Split REAC devices so that they’re blocked from sending audio to the Master
REAC device—otherwise, they’d conflict with the audio sent to the Master from the Slave.
See Chapter 7 for information on setting up Split REAC devices with an Ethernet switching
hub.
S-4000 Digital Snake Owner’s Manual

6—Using the S-4000 System
Setting the REAC MODE Switches
The REAC MODE switch on the S-4000S/S-4000H is recessed
from the front panel so that its setting can’t be changed
inadvertently. To change the switch setting, use a blunt-tipped
instrument such as a ball-point pen, mechanical pencil, etc.
With their power off, set the units as follows:
1.
On the S-4000S, set the REAC MODE switch to M.
2.
On the S-4000H, set the REAC MODE switch to S.
If the REAC MODE switch setting is changed when the unit is powered on, the new setting won’t
take effect until the unit is powered off and then back on again.
Component Connections
AC Power Connections
On the S-4000S:
•
Connect one end of the supplied AC power cord to a grounded AC outlet,
and the other end to the INT. POWER AC INPUT jack to provide power for the

Cable Requirements
A single cable REAC-to-REAC connection requires a standard Cat5e Ethernet cable with RJ45 plugs
wired in a crossover configuration. The maximum length for a single cable is 100 meters (330 feet).

As a reminder, a “REAC-to-REAC” connection means connecting directly from REAC device to
REAC device, with no switching hub in between.
If a crossover cable is not available, two Cat5e straight-through cables coupled with a Cat5e crossover
adaptor can be used for a REAC-to-REAC connection. In such cases, the total cable length—including
the crossover adaptor—must not exceed 100 meters.

Connecting Cables to the REAC Ports
The S-4000S and S-4000H each feature two REAC ports—one labeled MAIN and the other BACKUP.
The MAIN REAC port provides the primary REAC connection.
For the primary REAC-to-REAC connection:
•
Connect one end of a Cat5e crossover cable to the MAIN REAC port on the S-4000S, and the
other end to the MAIN REAC port on the S-4000H.
-‡{äää

The BACKUP REAC port provides a redundant REAC connection in case the MAIN REAC connection
fails. This redundancy requires a second Cat5e cable.
For the redundant REAC-to-REAC connection:
•
Connect one end of a second Cat5e crossover cable to the BACKUP REAC port on the S-4000S,
and the other end to the BACKUP REAC port on the S-4000H.

REAC Cable Length Extension
If necessary, the REAC cable length can be extended by placing an Ethernet switching hub in-line to
refresh the REAC signal. Multiple switching hubs can be used (up to four total), with a maximum cable
length of 100 meters between hubs. (Total cable length with four switching hubs: 500 meters.)
See Chapter 5 for a discussion about Ethernet cables. See the Appendices for a crossover cable
wiring diagram and Ethernet switching hub requirements.
Use Cat5e straight-through cables to connect REAC devices to the ports on the switching hub. If
multiple hubs are used, use Cat5e crossover or straight-through cables to connect hub-to-hub.

Some switching hubs have ports that allow the use of either crossover or straight-through
cables—they will detect the type of cable that’s connected and adjust the signal transfer
accordingly. Consult the documentation for the switching hub to determine what type of cables
can be used.
Using an Ethernet Switching Hub with Redundant REAC Connections
If an Ethernet switching hub with at least four ports is used in-line for cable length extension, the
S-4000S and S-4000H MAIN and BACKUP REAC ports can be connected to the ports on a single hub.
The proper signal negotiation will be handled within the switching hub. (See the diagram on the
following page.)
If you connect both the MAIN and BACKUP REAC ports to a single switching hub, you are
weakening the redundancy of the system somewhat—if the switching hub fails, both the MAIN
and BACKUP connections fail along with it. Therefore, in critical installations you may want to
consider using separate switching hubs for the MAIN and BACKUP REAC device connections.

switching hubs in-line (four total) for the MAIN and BACKUP connections.
REAC Connection Notes
•
The REAC connection can be “hot-swapped”—that is, connections can be made when the
S-4000S and S-4000H units are powered on.
•
The system is designed so that operation will inaudibly switch to the BACKUP REAC port should
the MAIN REAC connection fail. However, in some circumstances, this switch-over may result in
brief noise at the system’s audio outputs.
•
If the REAC cable is disconnected while MUTE ALL OUTPUTS is held, it’s possible that one of the
S-4000 units will remain in a muted state when MUTE ALL OUTPUTS is released. If this occurs,
use the following procedure:
1. Reconnect the REAC cable.
2. Press and release MUTE ALL OUTPUTS.
Notes About Handling Cat5e Cables
54
•
Do not subject the Cat5e cable to stress or physical shock.
•
Do not bend the Cat5e cable within a range of 25 mm.
•
Do not fasten Cat5e cables in a tight bundle.
•
Avoid laying multiple Cat5e cables in a parallel orientation over long distances.
•
Avoid laying Cat5e cables near noise sources (AC power cables, motors, fluorescent lighting,
etc.).

Connecting the S-4000R Remote Controller
Using the supplied RS-232C cable, connect the S-4000R’s REMOTE jack to the REMOTE jack on either
the S-4000S or S-4000H.
Power is supplied to the S-4000R through the REMOTE connection. The S-4000R’s POWER indicator
will light when receiving power.
If you require a longer cable than the one provided, you can use an off-the-shelf RS-232C cable or
fabricate your own. See Appendix B: Connector Information for an RS-232C pin out diagram.
The S-4000R can be connected to either the S-4000S or S-4000H. Connect it to whichever
device location is most convenient for you.
The REMOTE connections can be hot-swapped—that is, connections can be made when the
S-4000S and S-4000H units are powered on. This allows you to move the S-4000R from stage
to FOH without shutting down the system’s power first.
Multiple S-4000R units can be simultaneously connected to all S-4000S and S-4000H units in
the S-4000 System. See Chapter 7 for more information.

Ó
"/
When connecting unbalanced sources that require long cable runs (over 6 meters), a direct box
or balancing adaptor placed in-line near the source is recommended for the best audio quality
and noise rejection.
To connect high-impedance sources—such as the output of an electric guitar or bass with passive
pickups—use a direct box or impedance-matching transformer in-line.
Howling (feedback) could be produced depending on the location of microphones relative to
speakers. This can be remedied by:
•
changing the orientation of the microphone(s).
•
relocating the microphone(s) to a greater distance from the speakers.
•
lowering volume levels.

Muting the System Outputs
Ordinarily, when plugging and unplugging devices to and from the
audio inputs on the S-4000S and S-4000H units, the volume of all
devices connected to the S-4000 System’s audio outputs should be
lowered.
However, this may be impractical in some circumstances. In such
cases, you can temporarily mute the sound coming from the S-4000
System’s audio outputs.
˜`ˆV>̜À
1.
On the S-4000S or S-4000H front panel, press and hold the MUTE ALL OUTPUTS button. After
approximately 1.5 seconds, its indicator will light. No sound is output while the indicator is lit.
2.
When you have finished making input connections to the unit, release MUTE ALL OUTPUTS.
The system outputs will become un-muted a few seconds after releasing MUTE ALL OUTPUTS.
If audio is passing through the system when MUTE ALL OUTPUTS is released, the sound may be
distorted until the system outputs are completely un-muted.
Note that MUTE ALL OUTPUTS only mutes the outputs of the S-4000 System, and not the
outputs of other devices. Before connecting the audio outputs on the S-4000S and S-4000H
units to the audio inputs of other devices, always turn down the volume or turn off the power
on the receiving devices.
When an S-4000R is connected to the system, its CHANNEL display flashes when the audio
outputs are muted using MUTE ALL OUTPUTS.
If the REAC cable is disconnected while MUTE ALL OUTPUTS is held, it’s possible that one of the
S-4000 units will remain in a muted state when MUTE ALL OUTPUTS is released. If this occurs,
use the following procedure:
1.
Reconnect the REAC cable.
2.
Press and release MUTE ALL OUTPUTS.

S-4000S Input Channel Settings
With the S-4000R unlocked, use the following procedures to adjust settings on the S-4000S input
channels.
To retain your changes to the S-4000S input channel settings, lock the S-4000R before powering
down the S-4000 System. When the system is powered up, the settings will return to the state
they were in when the S-4000R was last locked. It’s also a good idea to store your custom
settings to a memory preset as well (see the next section for information).
The S-4000H’s eight input channels do not have any adjustable features. However, they can still
be selected with the CHANNEL knob for the purpose of viewing their input levels on the LED
input meter. They are represented on the S-4000R as Channels 33-40.
Selecting a Channel for Editing
Use the CHANNEL knob to select the desired S-4000S channel for editing (1-32). The currently
selected channel is shown in the CHANNEL display.

The indicator lights surrounding the GAIN knob show the currently selected channel’s gain
setting.
To adjust the input level on an S-4000H input, adjust the level at the sending device.
Input Pad
Each S-4000S input channel features a switchable input pad. When
the pad is engaged, the channel’s input sensitivity is reduced by 20
dBu.
Use the pad when connecting a “hot” audio source to an S-4000S
input—one whose signal exceeds 0 dB (and causes the clip indicator
to light) even when the channel’s GAIN knob is at its lowest setting.
S-4000 Digital Snake Owner’s Manual

6—Using the S-4000 System
Stereo Link
The Stereo Link function allows you to link odd/even adjacent S-4000S input channel pairs (1/2, 3/4,
etc.). When channels are linked, gain and pad settings made on one channel of the linked pair will be
duplicated on the other. This can be convenient when audio devices with stereo outputs are connected
to the S-4000S.
With the S-4000R unlocked, use the following procedure to link a pair of channels:
1.
Using the CHANNEL knob, select one channel of the pair that you wish to link together. For
example, if you wish to link Channels 7 and 8, choose either “07” or “08”.
2.
While holding CLIP CLEAR•ENTER, turn the CHANNEL knob clockwise.
3.
Release CLIP CLEAR•ENTER.
When channels are linked, their channel numbers are displayed with two periods (.), as shown in the
following examples:
>˜˜iÃÊÇÊ>˜`Ênʏˆ˜Ži`\
>˜˜iÃÊΣÊ>˜`ÊÎÓʏˆ˜Ži`\
1.
Using the CHANNEL knob, select one channel of the linked pair that you wish to unlink.
2.
While holding CLIP CLEAR•ENTER, turn the CHANNEL knob counterclockwise.
3.
Release CLIP CLEAR•ENTER.
Stereo Link Notes
•
Only odd/even adjacent pairs can be linked (1/2, 3/4, etc.).
•
When a channel pair is linked, the current gain and pad settings of the odd-numbered channel
will be copied to the even-numbered channel.
•
When a channel pair is unlinked, each channel’s gain and pad settings will remain in the same
state as when they were linked.
•
While channels are linked, their phantom power status can still be set independently.
•
S-4000H inputs (33-40) cannot be linked.

The standard S-4000 System provides 40 channels of audio in a 32x8 configuration. By adding
additional systems, you can easily expand your audio I/O as needed.
Each additional system increases your audio I/O capability, as shown in the following table:
Number of S-4000 Systems
Total I/O Capability
1
32x8
2
64x16
3

128x32
Remote Control and Monitoring of Multiple Systems
There are two ways to accomplish remote control and signal level monitoring of multiple systems:
•
Multiple S-4000R Units—Connect
s
one or two S-4000R units to each S-4000 System and control
each 32x8 setup independently.
•
A personal computer with multiple RS-232C serial ports and the S-4000 RCS—Connect
S
a REMOTE
jack from each S-4000 System to an RS-232C port on the personal computer running the S-4000
RCS. See the previous section for information on the S-4000 RCS.
To identify S-4000S channels, use the included adhesive-backed number label sheets to affix
channel numbers to the S-4000S units’ front panel inputs and outputs.

Splitting Stage Audio to Multiple Destinations
As we’ve discussed previously, REAC uses Ethernet networking technology to transfer audio signals.
Besides providing great sound quality and inexpensive and convenient installation, this allows for one
more huge benefit: pain-free audio splits using standard Ethernet hardware.
By integrating an Ethernet switching hub into the REAC system, S-4000S source signals can be split
to multiple additional S-4000H units. This allows you to send stage audio to multiple destinations in
addition to the FOH position, such as:
•
a monitor console.
•
a multitrack recorder.
•
a remote truck.
•
a broadcast feed.
•
a secondary FOH console.
•
anywhere else you need to send stage audio.
Traditionally, when using an analog snake system, audio splits are taken directly at the source. This
requires the use of expensive and bulky transformer-based audio splitters, as well as an additional
analog snake for each split destination. Besides this, analog signal splitting can reduce the source
signals’ quality and greatly increase the potential for introducing noise into the entire sound
reinforcement system via ground loops and RF interference.
Using REAC, splitting the stage audio in an S-4000 System is extremely easy. Simply add a switching
hub and an S-4000H unit for each split destination, hook them together with Cat5e cables, and you’re
ready to go! Besides this setup convenience, REAC splits provide pristine audio quality—once the input
signals are converted to digital data in the S-4000S, they can be split as many times as you wish with
absolutely no loss in quality.
What You’ll Need
To split the S-4000S’s 32 channels of input audio, you’ll need:
•
an Ethernet switching hub with enough ports to connect each REAC device.
•
an additional S-4000H unit for each split destination.
•
straight-through Cat5e Ethernet cables.
Ethernet Switching Hub Requirements
To work with REAC, an Ethernet switching hub must meet the following requirements:
•
1000BASE-T transmission speed (IEEE802.3ab, Gigabit Ethernet)
•
Support for 100BASE-TX devices (IEEE802.3u, Fast Ethernet)
•
Bi-directional (full-duplex) communication
Connect REAC devices only to switching hub ports that support 100BASE-TX.

Setting the REAC MODE Switches
See Page 49 for a discussion about the REAC MODE switches and how they affect REAC signal
flow.
With their power off, set the units as follows:
1.
On the S-4000S, set the REAC MODE switch to M.
2.
On the primary S-4000H (usually at the FOH position), set the REAC MODE switch to S.
3.
On each S-4000H used to receive audio splits from the stage, set the REAC MODE switch to SP.
If the REAC MODE switch setting is changed when the unit is powered on, the new setting won’t
take effect until the unit is powered off and then back on again.
REAC Connections
For the primary REAC connections:
•
Using Cat5e straight-through cables, connect the MAIN REAC ports on the S-4000S/H units to
ports on the switching hub.
For the redundant REAC connections:
•
Using Cat5e straight-through cables, connect the BACKUP REAC ports on the S-4000S/H units to
ports on the same switching hub (or a second switching hub).

The cable length from each REAC device to the switching hub must not exceed 100 meters. If
you need to extend the cable length of a particular REAC device connection beyond 100 meters,
a separate switching hub must be used in-line. See “REAC Cable Length Extension” in Chapter
6 for more information.
76
S-4000 Digital Snake Owner’s Manual
7—Advanced Use
As mentioned earlier in the manual, some switching hubs have ports that allow the use of
either crossover or straight-through cables—they will detect the type of cable that’s connected
and adjust the signal transfer accordingly. Consult the documentation for the switching hub to
determine what type of cables can be used.
If you connect both the MAIN and BACKUP REAC ports to a single switching hub, you are
weakening the redundancy of the system somewhat—if the switching hub fails, both the MAIN
and BACKUP connections fail along with it. Therefore, in critical installations you may want to
consider using separate switching hubs for the MAIN and BACKUP REAC device connections.
Audio Connections and Power Up
Connect and power up devices in the following order:
In each of the following steps, allow each piece of equipment to finish its power-up sequence
before proceeding to the next step.
1.
Connect the system components as described here and in Chapter 6.
2.
Connect audio devices to the Master and Slave REAC devices’ inputs and outputs.
3.
Connect audio devices to the Split REAC devices’ outputs.
S-4000S and S-4000H audio connections are explained in Chapter 6.
4.
Turn on any devices connected to the Master and Slave REAC devices’ audio inputs.
5.
Turn on the power on the switching hub(s).
6.
Turn on the front panel power switches on the Master, Slave, and Split devices so that their INT
indicators light.
7.
Turn on the power to the audio devices (mixing consoles, power amplifiers, monitor speakers,
etc.) connected to the Master, Slave, and Split devices’ audio outputs.
Notes on Split Setups
•
A Split REAC device can only receive audio from the Master REAC device—it can’t receive audio
from a Slave REAC device (or another Split device).
•
When a unit is set as a Split REAC device, its audio inputs are disabled.
•
An S-4000R can be connected to the REMOTE connector on a Split REAC device. However, it
can only be used for system and signal level monitoring—adjustment of S-4000S inputs is not
possible. (If you need to adjust the signal level coming from a Split device’s outputs, use the input
trim controls on the receiving device.)

MIDI Communication Via REAC
In addition to audio communication, the REAC connection allows for MIDI communication as well.
Both the S-4000S and S-4000H units feature MIDI IN and OUT jacks. When you connect MIDI devices
to these jacks, they can send and receive MIDI information to and from each other via REAC. For this
application, you can think of the REAC connection as a “MIDI cable extender.”
REAC’s ability to pass along MIDI information can prove useful for synchronizing devices via MIDI
Time Code (MTC), triggering MIDI sound modules and samplers, and integrating MIDI remote control
devices.
Notes on REAC MIDI Communication
78
•
MIDI data received at the MIDI IN connector of the Master REAC device is transmitted unchanged
to the MIDI OUT connectors of the Slave REAC device and any SPLIT REAC devices.
•
MIDI data received at the MIDI IN connector of the Slave REAC device is transmitted unchanged
to the MIDI OUT connector of the Master REAC device.
•
When an S-4000S or S-4000H is set as a Split REAC device, its MIDI IN connector is disabled.
•
A Split REAC device can only receive MIDI data from a Master REAC device (MIDI data reception
from a Slave REAC device is not possible).

Appendix C: Ethernet Switching Hub Requirements
To be used in a REAC system, an Ethernet switching hub must meet the following requirements:
•
1000BASE-T transmission speed (IEEE802.3ab, Gigabit Ethernet)
•
1000BASE-T switching hub you use support for 100BASE-TX devices (IEEE802.3u, Fast Ethernet)
•
Bi-directional (full-duplex) communication
Connect REAC devices only to switching hub ports that support 100BASE-TX.
The transmission protocol for REAC is based on 100BASE-TX (Fast Ethernet). To transfer 40
channels of digital audio, REAC uses the full bandwidth of this protocol. However, some
100BASE-TX switching hubs cannot handle this amount of data traffic. Gigabit Ethernet
switching hubs can handle a larger amount of data traffic, so we recommend them for use
with REAC devices (just be sure that the Gigabit switching hub you use supports 100BASE-TX
devices).
When using switching hubs in-line for REAC cable length extension, a maximum of four hubs
can be used. (Total cable length with four switching hubs: 500 meters. See Chapter 6 for
more information.)
Consult the switching hub’s documentation for information on its proper use.

* When a switching hub is used in-line with REAC cables, the network latency will increase by the amount of
processing delay introduced by the hub itself. The actual delay is dependant upon the specifications of the
hub, though the maximum delay amount for a single hub should be about 200 microseconds.
