��

• 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.

��

��

• 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.

��

��

• The unit should be located so that its location or position does not interfere with its proper ventilation.

��

��

• Always grasp only the plug on the power-supply cord when plugging into, or unplugging from, an outlet or this unit.

��

��

• 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.

��

��

• Never handle the power cord or its plugs with wet hands when plugging into, or unplugging from, an outlet or this unit.

��

��

• 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 (p. **).

��

��

• Whenever you suspect the possibility of lightning in your area, pull the plug on the power cord out of the outlet.

��

��

• 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.

��

��

• 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.

��


�

��

• 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.)

Using the Unit Safely

6 S-4000 Digital Snake Owner’s Manual

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:

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.

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.

• 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.

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).

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 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 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:

• A crossover cable

must

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.



• 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 A

ppendix 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).

��

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 NE8MC-

1-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.



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 a “Master” REAC device to one or more “Split” REAC devices.

See Chapter 7 for information on splitting audio to multiple destinations.

��

36

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.



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).

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-digital

(A/D) and

digital-to-analog

(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).



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 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 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 module provides two REAC connection ports—one for the main REAC connection, the other for a redundant backup.

•

one S-BP Blank Panel

—This 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:



•

Better analog signal quality

—By 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 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 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.)


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 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 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 meter male breakout cable to connect S-4000H outputs to audio destinations

(DB-25 connector to eight male XLR connectors).

•

SC-A0805DF

—4.5 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


for information about the S-4000H’s DB-25 connectors.



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.


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 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 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-4000R provides signal status indicators for all of the S-4000 System’s 40 input channels.

•

Clip indicators

—The S-4000R provides channel clip indicators for all of the S-4000 System’s 40 input channels.

•

Memory presets

—10 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.RSSAmerica.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.

Install the slide-on connector guard on the S-4000H front panel to provide protection for the DB-25 input and output connectors. When installed, the connector guard will support DB-25 connectors that are plugged in the front panel, and prevent them from being bent due to accidental stress or the weight of the connector’s cable.

1. Turn off the power on all equipment and disconnect all cables from the S-4000H unit.

2. Slide the DB-25 connector guard over the S-4000H front-panel lugs as shown.

3. To hold the connector guard in place, use the supplied screws as shown.

44

Make sure that the connector guard is installed as shown in the above illustrations. If its orientation is reversed, it won’t remain attached.



Rack-Mounting the S-4000R

The S-4000R Remote Controller is designed for handheld or desktop use. If desired, it can be rackmounted by installing the included rack-mount brackets.

Use the following procedure to install the rack-mount brackets on the S-4000R.

1. Disconnect the RS-232C cable from the S-4000R unit.

2. Install the S-4000R rack-mount brackets with the supplied screws as shown in the following diagram.



Using the REAC Connector Covers (S-4000S and S-4000H)

The REAC ports on the S-4000S and S-4000H units feature rugged Neutrik® EtherCon® connectors. As discussed in Chapter 5, they can accept either standard RJ45 plugs or RJ45 plugs housed in EtherContype connectors.

When using an Ethernet cable with standard RJ45 plugs (such as the cable included with the S-4000

System), fit the included REAC connector covers on the REAC ports as shown.

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

cannot

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.



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

S-4000S’s internal power supply.

On the S-4000H:

• 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

S-4000H’s internal power supply.

Use only the supplied power cords to prevent damage to the units.

An optional S-240P External Power Supply Unit can be used to supply redundant backup power to an S-4000S or S-4000H unit. Visit www.RSSAmerica.com or contact an RSS dealer for more information.



REAC Connections

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.

The S-4000 System includes a 10 meter Cat5e Ethernet crossover cable. This cable length is appropriate for testing and small installations. If a longer cable length is required, you’ll need to provide Cat5e Ethernet cabling with the appropriate length for your particular application.

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 (such as the one included with S-4000 System) to the MAIN REAC port on the S-4000S, and the other end to the MAIN REAC port on the

S-4000H.

��

��

��

��

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.

��

��

��

��

If redundant operation is not required, use only the MAIN REAC ports.

For proper system operation, the REAC port on one device must be connected to the likenamed REAC port on the other device—that is, always connect MAIN to MAIN, and BACKUP to

BACKUP.



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.



��

��

��

��

��

��

��

��

��

��

��

Note: The connection shown above will work when extending the REAC cable length (MAIN and

BACKUP) a total of 200 meters. If you need to extend the distance another 100 meters, use separate 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

• 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


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.



Audio Connections

When making audio input connections with the S-4000S and/or S-4000H units powered on, always press and hold the MUTE ALL OUTPUTS button on the respective unit’s front panel so its indicator lights. This will mute the sound coming from the S-4000 System’s audio outputs and prevent possible damage to connected speakers and other devices. See Page 63 for more information about MUTE ALL OUTPUTS.

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 to prevent possible damage.

To prevent hazard or damage, ensure that only microphone cables and microphones conforming to IEC-268-15A are connected.

Afin d’éviter tout risque ou dommage, ne brancher que des câbles de microphone et des microphones conformes à la norme IEC-268-

15A.



To facilitate custom labeling for a particular installation or multiple S-4000 Systems, the S-4000S is shipped from the factory without channel number labels on its input and output modules.

See


for an illustration showing the S-4000S’s input and output channels as they correlate to the S-4000H’s audio I/O channel numbers and input channel selection on the S-4000R.

If desired, use the included adhesive-backed number label sheets to affix channel numbers to the S-4000S’s input and output modules.

S-4000S Audio Inputs

The S-4000S’s audio inputs are used to send source audio signals to the S-4000H’s audio outputs.

Connect the output of balanced audio devices (microphones, instrument outputs, etc.) to the 32 balanced audio inputs on the S-4000S front panel.

To connect unbalanced sources:

• use a direct box—such as the BOSS DI-1—or balancing adaptor in-line

—or—

• a cable adaptor with the following wiring:

��

�

�

�

��

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.



Input Status Indicators

Each S-4000S input has three status indicators:

•

+48V

—lights orange when +48 V phantom power is supplied from the channel.

•

CLIP

—lights red when the input signal exceeds 0 dB.

•

SIG

—lights green when the input signal is greater than -40 dB.

The CLIP and SIG signal status indicators represent the signal level in the digital domain (post-

A/D conversion). Signals exceeding 0 dB will clip, resulting in distortion.

Preamp gain and phantom power on/off status are controlled from the S-4000R. See Pages 66-69 for more information.

S-4000S Audio Outputs

The S-4000S’s audio outputs are used to receive audio signals connected to the S-4000H’s audio inputs.

Connect the S-4000S’s eight balanced audio outputs to the balanced audio inputs of the desired devices.

If you need to connect the S-4000S’s audio outputs to unbalanced devices, use a direct box or balancing adaptor in-line, or a cable adaptor with the wiring described in the previous section

(

S-4000S Audio Inputs

).



S-4000H Audio Connections

The S-4000H’s balanced audio I/O is provided in groups of eight on DB-25 connectors. See

Appendix

S-4000H Audio Outputs

The S-4000H’s audio outputs are used to receive audio signals connected to the S-4000S’s audio inputs.

Connect the S-4000H’s balanced audio outputs to the destination device’s balanced line level (+4 dBu) inputs.

In most cases, you’ll use a breakout cable—such as the RSS SC-A0805DM—for connecting the

S-4000H’s audio outputs to the balanced inputs on the receiving device. This cable has a DB-25 connector on one end and eight male XLR connectors on the other.

If the receiving audio device’s inputs are provided on DB-25 connectors, DB-25-to-DB-25 cables with the appropriate wiring can be used. Refer to the documentation for the receiving device for information on its DB-25 input wiring.

S-4000H Audio Inputs

The S-4000H’s audio inputs are used to send source audio signals to the S-4000S’s audio outputs.

Connect the sending device’s balanced line level (+4 dBu) outputs to the S-4000H’s balanced audio inputs.

In most cases, you’ll use a breakout cable—such as the RSS SC-A0805DF—for connecting the sending device’s balanced audio outputs to the S-4000H’s DB-25 audio input. This cable has a DB-25 connector on one end and eight female XLR connectors on the other.



If the receiving audio device’s outputs are provided on a DB-25 connector, a DB-25-to-DB-25 cable with the appropriate wiring can be used. Refer to the documentation for the sending device for information on its DB-25 output wiring.

The signal level received at the S-4000H’s inputs can be monitored from the S-4000R. See Page

66 for more information.

Powering Up/System Status Indicators

Powering Up

Connect and power up devices in the following order:

Turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices.

Additionally, 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 previously.

2. Connect audio devices to the S-4000S and S-4000H inputs and outputs as described previously.

3. Turn on any devices connected to the S-4000S and S-4000H units’ audio inputs.

4. Turn on the front panel power switches on the S-4000S and S-4000H units so that their INT indicators light.

The S-4000S and S-4000H units are equipped with protection circuits. A brief interval (a few seconds) after power up is required before the units will operate normally.

5. Turn on the power to the audio devices (mixing consoles, power amplifiers, monitor speakers, etc.) connected to the S-4000S and S-4000H units’ audio outputs. (Note: It’s always best to power on any speakers or amplification systems last.)



Checking the System Status Indicators

The S-4000S, S-4000H, and S-4000R have system status indicators that allow you to monitor the integrity of the component connections when the system is powered up.

Power Indicators

S-4000S/S-4000H

• INT

—This indicator lights when the unit is receiving power from its internal power supply.

• EXT

—This indicator lights when the unit is receiving power from an optional S-240P External Power Supply Unit connected to its rear panel EXT. POWER DC INPUT jack.

Visit www.RSSAmerica.com or contact an RSS dealer for information about the S-240P External

Power Supply Unit.

S-4000R

The POWER indicator on the S-4000R will light when it’s receiving power from an S-4000S or S-4000H.

REAC Communication

REAC Ports (S-4000S/S-4000H)

The indicator on the REAC port (MAIN and/or BACKUP) flashes when communication is established with another REAC device. If communication fails, the indicator will go out.

REAC System Indicators

The S-4000S, S-4000H, and S-4000R have REAC indicators that light when REAC communication is established. If communication fails, these indicators flash.

��



Remote Communication

CTRL Indicators

The S-4000S, S-4000H, and S-4000R have CTRL indicators that show when RS-232C communication is established within the system.

•

On the S-4000S and S-4000H units

—

• CTRL lights when an RS-232C device (such as the S-4000R) is connected to the S-4000 System and communication is established.

• If no RS-232C device is connected to the S-4000 System—or if a device is connected and communication is not established—

CTRL will not light.

• If the RS-232C device is disconnected after communication has been established, CTRL will flash for 10 seconds.

•

On the S-4000R

—CTRL lights when communication is established with the S-4000 System. If communication fails, CTRL will flash.

For more information about the system status indicators, see

Appendix A: Troubleshooting

.

Powering Off

Perform the following steps to power off the S-4000 System.

1. Turn down the volume and power off any devices connected to the S-4000S and S-4000H units’ inputs and outputs. (Note: It’s always best to turn down the volume and power off any speakers or amplification systems first.)

2. If an S-4000R is connected to the system, press and hold the S-4000R’s LOCK button until its indicator lights. (Locking the S-4000R retains the current S-4000S input settings when the power is turned off.)

3. Power off the S-4000S and S-4000H units. To prevent the units from being powered up again inadvertently, unplug the power cords from the AC outlets after the front panel power switches have been turned off.

If an S-240P External Power Supply Unit is providing power to an S-4000S or S-4000H, the

S-4000S or S-4000H unit will keep operating even if the front panel power switch is in the OFF position.



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.

��

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.


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 LED 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.



Using the S-4000R Remote Controller

When the S-4000R is connected to the S-4000 System, you can:

•

control S-4000S input channel functions

—including preamp gain, pad, and phantom power.

•

monitor signal level status of the system’s input channels

—including the presence of signal and overload (clip).

•

monitor the level of the system’s input channels

—using the eight-segment LED input meter.

•

monitor system status

—using the various indicators on the S-4000R panel.

•

store and recall

—10 different sets of S-4000S channel settings

To facilitate custom labeling for a particular installation or multiple S-4000 Systems, the S-4000S is shipped from the factory without channel number labels on its input modules. See

Appendix B:

Connector Information

for an illustration that identifies the S-4000S’s input channels for channel selection on the S-4000R.

When the S-4000R is connected to a unit set as a Split REAC device, only system and signal level monitoring is possible. See Chapter 7 for more about split setups.

In the following sections, we’ll show you how to use the S-4000R’s functions. Before proceeding, make sure that the S-4000R is connected to the S-4000S or S-4000H as described on Page 55.

Lock Mode

The S-4000R has a Lock mode that blocks the editing of S-4000S input channels. This protects the current channel settings from accidental changes during a live performance.

•

To lock the S-4000R

—press LOCK so its indicator lights. When locked,

S-4000S channel settings cannot be adjusted.

•

To unlock the S-4000R

—press and hold LOCK until its indicator goes out

(approximately 1.5 seconds). When unlocked, S-4000S channel settings can be adjusted.

When the S-4000R is powered up, it will remember its last Lock mode state (locked or unlocked).

When the S-4000R is in a locked state, you can still use the CHANNEL knob to select channels whose signal level you want to monitor with the LED input meter.



Monitoring Input Signals

Signal Status Indicators

The S-4000R has two rows of signal status indicators that allow you to monitor the signal activity on the S-4000 System’s 40 audio inputs (1-32 for the S-4000S and 33-40 for the S-4000H).

• SIG—lights green when the input signal level is higher than -40 dB on a particular channel.

• CLIP—lights red when the input signal exceeds 0 dB. Once a CLIP indicator lights, it stays lit until cleared with the CLIP CLEAR•ENTER button.

The signal status indicators represent the signal level in the digital domain (post-A/D conversion).

Signals exceeding 0 dB will clip, resulting in distortion.

Clearing the CLIP Indicators

When an input signal on a particular channel exceeds 0 dB, the corresponding signal status CLIP indicator will light, and the CLIP CLEAR•ENTER button will flash.

To clear all lit CLIP indicators, press CLIP CLEAR•ENTER so its indicator goes out.

To keep a channel’s CLIP indicator from lighting again, lower the preamp gain on that particular channel (see Page 67 for more information).

The signal status indicators also warn you when there’s a problem with the system. See

Appendix

A: Troubleshooting




LED Input Meter

The S-4000R features an eight-segment LED input meter for precise input signal measurement.

To view an input channel’s signal level with the LED input meter, turn the CHANNEL knob to select the desired channel (1-32 for the S-4000S and 33-40 for the S-4000H).

The LED input meter represents the signal level in the digital domain (post-A/D conversion).

CLIP will light when the signal exceeds 0 dB.

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 LED display.



Setting the Preamp Gain

Use the following procedure to set the preamp gain on an S-4000S input channel:

1. Select the desired channel (1-32) with the CHANNEL knob.

2. Send an input signal to the selected channel.

3. While viewing the input level on the LED input meter, use the GAIN knob to adjust the preamp gain to the desired level.

If the signal level exceeds 0 dB, the CLIP indicators on the LED input meter and signal status indicators will light and distortion will occur. For the best audio quality, set the preamp gain so the meter reads between -18 and -3 dB on the input signal’s loudest peaks.

4. Repeat Steps 1-3 to adjust other channels’ preamp gain.

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.



Use the following procedure to engage the input pad on a particular channel:


2. Press PAD so its indicator lights.

3. Repeat Steps 1-2 to engage the input pad on other channels.

To turn off a pad, select the channel with the CHANNEL knob, and then press PAD so its indicator goes out.

While a channel’s input pad setting (on/off) is changed, its output is temporarily muted to avoid noise.

Phantom Power

Each of the S-4000S’s inputs can supply +48 V phantom power to devices that require it, such as condenser microphones or active direct boxes.

Always turn the phantom power off when connecting any device other than condenser microphones that require phantom power. You risk causing damage if you mistakenly supply phantom power to dynamic microphones, audio playback devices, or other devices that don’t require such power. Be sure to check the specifications of any microphone you intend to use by referring to the manual that came with it. (This instrument’s phantom power: 48 V DC, 14 mA Max.)

Use the following procedure to turn on phantom power on a particular channel:


2. Press PHANTOM +48 V so its indicator lights.

3. Repeat Steps 1-2 to turn on other channels’ phantom power.

To turn off a channel’s phantom power, select the channel with the CHANNEL knob, and then press

PHANTOM +48 V so its indicator goes out.

While a channel’s phantom power setting (on/off) is changed, its output is temporarily muted to avoid noise.



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:

��

With the S-4000R unlocked, use the following procedure to unlink a channel pair:

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.



Memory Function

The S-4000R features 10 user-storable memory presets. A memory preset contains channel settings

(preamp gain, pad, phantom power, and stereo link) for all of the S-4000S’s 32 input channels. Using memory presets, you can quickly reconfigure the S-4000S for frequently used audio input setups.

If the S-4000R is in a locked state, it’s not necessary to unlock the unit before selecting or storing presets. The unit is automatically unlocked when entering a Memory mode.

Storing a Memory Preset (Memory Store Mode)

To store the current settings to a memory preset:

1. Press and hold STORE until its indicator lights solid.

2. Turn the CHANNEL knob until the desired memory preset (0-9) is shown in the LED display.

The currently loaded preset displays a period (.) next to the preset number. If the currently loaded preset is in a state different than the stored version, two periods are displayed.

70

��

3. Press CLIP CLEAR•ENTER to finalize your selection. (To exit Memory Store mode without storing the current settings, press STORE so that its indicator goes out instead.)

4. If you wish to store the current settings to another memory preset, repeat Steps 2-3. To exit

Memory Store mode, press STORE so that its indicator goes out.

Recalling a Memory Preset (Memory Recall Mode)

To recall a memory preset:

1. Press and hold RECALL until its indicator lights solid.

2. Turn the CHANNEL knob until the desired memory preset (0-9) is shown in the LED display.

The currently loaded preset displays a period (.) next to the preset number. If the currently loaded preset is in a state different than the stored version, two periods are displayed (see the illustration above). If you wish to retain the current settings, exit as indicated in Step 3.

3. Press CLIP CLEAR•ENTER to finalize your selection. (To exit Memory Recall mode without making a selection, press RECALL so that its indicator goes out instead.)

4. If you wish to select another memory preset, repeat Steps 2-3. To exit Memory Recall mode, press

RECALL so that its indicator goes out.

While a memory preset is recalled, all system outputs are temporarily muted.

Using Two S-4000R Units in a Single S-4000 System

As discussed in Chapter 6, the S-4000R can be connected to either the S-4000S or S-4000H. However, if you have a second S-4000R (available separately), you can connect one to each unit. This allows for control and signal monitoring of the S-4000 System at the location of either S-4000 unit.

The following behaviors occur when two S-4000Rs are used in a single system:

• Only one S-4000R unit can be used to edit S-4000S channels and recall/store memory presets at any one time.

• When one S-4000R unit is in use, the other S-4000R unit automatically enters a locked state and its LOCK button flashes.

See “Using the S-4000R Remote Controller” in Chapter 6 for information on operating the

S-4000R.

Computer Control (S-4000 RCS)

The S-4000 Remote Control Software (S-4000 RCS) allows for the remote control and monitoring of the S-4000 System from a personal computer equipped with an RS-232C port.

Functionally, using the S-4000 RCS is similar to using the S-4000R Remote Controller, but with the conveniences provided by a personal computer.

S-4000 RCS features:

•

S-4000S input channel control screen

—View and adjust settings for all S-4000S channels from one screen.

•

Comprehensive input level meter screen

—View input activity of all input channels from one screen.

•

100 memory presets

—Store and recall up to 100 different S-4000S input setups.

•

Integrated monitoring and control of multiple systems

—You can connect up to four S-4000 Systems to multiple RS-232C ports on a personal computer. This allows for control and signal monitoring of multiple systems from a single interface.

Where to Get the S-4000 RCS

The S-4000 RCS is available as a free download from www.RSSAmerica.com. Refer to the documentation included with software for instructions on using it with the S-4000 System.

System Requirements

The S-4000 RCS is available for both Windows and Macintosh operating systems. Please visit www.RSSAmerica.com for the latest S-4000 RCS version and current computer and operating system requirements.


7—Advanced Use

System Expansion

Adding More I/O

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:

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 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 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.


7—Advanced Use

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:



• Bi-directional (full-duplex) communication

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.


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.)


7—Advanced Use

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.

78

Notes on REAC MIDI Communication

• 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:



• Bi-directional (full-duplex) communication


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.
