THE UNIT SAFELY

010

●

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.

.....................................................................................................

012a

●

Immediately turn the power off, remove the power plug 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

• The unit does not appear to operate normally or exhibits a marked change in performance.

.....................................................................................................

013

●

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.

.....................................................................................................

014

●

Protect the unit from strong impact. (Do not drop it!)

.....................................................................................................

015

●

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.

.....................................................................................................

016

●

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.

.....................................................................................................

026

●

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.

.....................................................................................................

101a

●

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

....................................................................................................

102b

●

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

....................................................................................................

103a

●

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.

....................................................................................................

104

●

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.

....................................................................................................

IMPORTANT NOTES

In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 2 and 3–4, please read and observe the following:

Power Supply

301

●

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.

307

●

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.

308

●

This device has no power switch. Disconnect the plug from the power outlet whenever shutdown of power is required. The power cord’s plug should be connected to the closest available power outlet to the device; this should be within immediate reach during use.

Placement

351

●

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.

352a

●

This device may interfere with radio and television reception. Do not use this device in the vicinity of such receivers.

352b

●

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.

355b

●

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.

360

●

Depending on the material and temperature of the surface on which you place the unit, its rubber feet may discolor or mar the surface. You can place a piece of felt or cloth under the rubber feet to prevent this from happening. If you do so, please make sure that the unit will not slip or move accidentally.

Maintenance

401a

●

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, nonabrasive detergent. Afterwards, be sure to wipe the unit thoroughly with a soft, dry cloth.

402

●

Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation.

Additional Precautions

552

●

Unfortunately, it may be impossible to restore the contents of data that was stored in the unit’s memory once it has been lost. Roland Corporation assumes no liability concerning such loss of data.

553

●

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.

556

●

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.

557

●

A small amount of heat will radiate from the unit during normal operation.

558b

●

To avoid disturbing your neighbors, try to keep the unit’s volume at reasonable levels (especially when it is late at night).

559a

●

When you need to transport the unit, package it in the box (including padding) that it came in, if possible. Otherwise, you will need to use equivalent packaging materials.

1—Introduction

Conventions Used in the Manual

Names

The S-1608/S-0816 Digital Snake System is comprised of three primary components:

• S-1608 Stage Unit

• S-0816 FOH Unit

• S-4000R Remote Controller

Throughout the text, the individual components’ names are often shortened, and referred to simply as “S-1608,” “S-0816,” and “S-4000R.” When a procedure or description refers to the entire system, the name “S-1608/S-0816 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-1608/S-0816 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-1608/S-0816 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-1608/S-0816 System will function just as well in any installation where an audio snake is required.

1—INPUT Connectors

Each Input Channel provides balanced input jacks with female XLR connectors. Each input has a variable gain preamp that accepts signals from -65 to +10 dBu (+28 dBu maximum). Additionally, there are three status indicators for each input:

•

CLIP

•

SIG

•

+48V

Although changes may not seem smooth when adjusting preamp gain using an S-4000R remote controller or an S-4000RCS (remote control software) on a computer, this is not a malfunction. Some noise is also generated when switching between the following gain levels. This is not a malfunction. Three locations when Pad=ON: +3 ↔ +2, -13 ↔ -14, -19 ↔ -30 (dBu) Three locations when Pad=OFF: -17 ↔ -18, -33 ↔ -34, -49 ↔ -50 (dBu)

The S-4000R upgrade allows the gain level to be verified with numerical values. See the Roland website for the version that supports this feature and how to upgrade. http://www.rolandsystemsgroup.net

—lights red when the input signal exceeds 0 dB (after A/D conversion).

—lights green when the input signal is greater than -40 dB (after A/D conversion).

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

Preamp gain adjustment and phantom power status can be controlled from the S-4000R Remote Controller or from a computer using the S-4000 RCS.

2—OUTPUT Connectors

Each Output Channel provides balanced output jacks with male XLR connectors. Signal output is +4 dBu typical, +22 dBu maximum.

3—REMOTE Indicator

The REMOTE indicator lights in orange when an S-1608/S-0816 system is communicating with another device via the RS-232C connection. If no RS-232C device is connected, or if a problem occurs in transmitting via the RS-232C connection, the indicator ﬂashes or goes off. See Page 47 for more information.

4—REMOTE Connector

This D-Sub 9-pin female connector is provided for remote control and signal monitoring of the S-1608/S-0816 System from an external device supporting the RS-232C serial interface protocol. Normally, you’d connect the S-4000R Remote Controller to this connector using the supplied DB-9 cable. If you’re using the S-4000 RCS on a computer, connect the computer’s RS-232C port to this connector.

See Chapters 6 and 7 for information about remote control of the S-1608/S-0816 System. See

This optical type digital out connector outputs the audio signal input to INPUT 1/2 of the S-1608/S-

0816.

6—[MUTE ALL OUTPUTS] Button

The [MUTE ALL OUTPUTS] button is a momentary switch used to temporarily mute the S-1608/ S-0816 System’s audio outputs. This allows for noise-free connection of audio input sources.

Press and hold the [MUTE ALL OUTPUTS] button. After approximately 1.5 seconds, its indicator lights. While the indicator is lit, the audio outputs of all connected REAC devices are muted.

The system outputs will become un-muted after [MUTE ALL OUTPUTS] is released. 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.

If the exhaust fan has stopped working for any reason, the [MUTE ALL OUTPUTS] indicator will flash. See:

S-1608/S-0816 System Overview

Concept

The S-1608/S-0816 System brings the digital revolution to the world of audio snakes. Using computer networking technology, the system allows you to transfer 24 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.

Things to Know

About REAC

About

At the heart of the S-1608/S-0816 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.

The S-1608/S-0816 system transfers a total of 24 channels of audio signal: 16 channels from the S1608 and 8 channels from the S-0816.

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 REAC Splitter S-4000-SP or Ethernet switching hubs

• Easy device splits using REAC Splitter S-4000-SP or Ethernet switching hubs

• Extremely low device-to-device transmission latency (The REAC network latency is about 375 microseconds. The signal latency for analog input to another analog output is about 1.2 milliseconds.)

If routed through the S-4000-SP REAC splitter or a switching hub, an approximate 200 microsecond delay is added for each device.

• Hot-swappable connection

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-1608/S-0816 System. Though the cables look the same on the outside, the RJ45 plugs are wired in different ways. With a:

•

crossover cable

result, the two RJ45 plugs on each end of a single cable are wired differently.

•

straight-through cable

arrangement (each plug is wired the same).

—some of the wires inside the cable are “crossed over” at each RJ45 plug. As a

—the wires inside the cable are connected to each RJ45 plug in the same

26 S-1608/S-0816 Digital Snake Owner’s Manual

5—S-1608/S-0816 System Overview

RJ45 plug REAC RJ45 receptacle

In the following cases, either a crossover or a straight-through cable can be used.

• When directly connecting the S-1608 and S-0816 via REAC

• When using the S-4000-SP REAC splitter to extend the REAC cable or to split connect a separate S-1608 or S-0816

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

fig.5-03.eps

As mentioned previously, Cat5e Ethernet cables use RJ45 plugs. Each REAC device provides an RJ45 receptacle for its REAC ports.

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.

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

meters. However, if you need to extend the cable length, you can use two cables (REAC cables or Cat5e 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

fig.5-04.eps

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

—The maximum length for a single REAC cable is 100

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

REAC device modes—including “Master,” “Slave,” and “Split”—are discussed starting on Page 38.

28 S-1608/S-0816 Digital Snake Owner’s Manual

5—S-1608/S-0816 System Overview

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 up to 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.

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

The S-1608 and S-0816 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-1608/S-0816 system provides variable gain preamps on each of its 24 audio inputs. This allows for signal optimization at the source, resulting in the highest A/D conversion quality.

(A/D) and

digital-to-analog

(D/A) conversion.

RS-232C Serial Interface

The S-1608 and S-0816 feature REMOTE connectors that support the RS-232C serial interface protocol. RS-232C is a standard communications interface found in computers.

The S-1608/S-0816 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 (S-4000 RCS).

If RS-232C devices are connected to the REMOTE connectors on both the S-1608 and S-0816, the system can be controlled from either device (though only one remote device can control the system at any given time).

The System Components: A Closer Look

S-1608 Stage Unit

The S-1608 is the stage connection interface for the S-1608/S-0816 System. Its box design supports 24 channels of audio input and output (I/O). As standard, it comes in a 16x8 conﬁguration—16 audio inputs and 8 audio outputs.

S-0816 FOH Unit

The S-0816 is the front-of-house (FOH) connection interface for the S-1608/S-0816 System. As such, its I/O conﬁguration is the opposite of the S-1608—8 audio inputs and 16 audio outputs.

As it name suggests, the S-0816 FOH Unit’s main application is near the FOH mixing console. However, the S-0816 can be used anywhere you need to receive stage audio from the S-1608—at a monitor console, a multi-channel recording device, a broadcast feed, etc. Additionally, multiple S0816 units can be used for split destinations when connected to the system via an Ethernet switching hub. See Chapter 7 for details.

About the Remote Controlled Preamps

Each input on the S-1608 and S-0816 employs a newly-developed variable gain preamp. Designed for warm and accurate sound reproduction, the preamp 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-1608/S-0816 System to an analog mixing console, you may be wondering why you need adjustable gain at the S-1608/S-0816 System’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-1608/S-0816 System’s inputs:

•

Better analog signal quality

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

Precautions for Rack Mounting

• When mounting the S-1608 or S-0816 in a rack, observe the following precautions to ensure efﬁcient and effective cooling.

- Ensure that the location provides good air ﬂow and ventilation.

- Do not allow the vents to become obstructed.

- Avoid using the S-1608 or S-0816 in sealed-type rack mounts. As this type of rack does not permit heated air within the rack to be expelled, the heated air is drawn into the S-1608 or S-0816 as a result, thus preventing adequately efﬁcient cooling.

- If the rack’s rear panel is not removable, ensure that a ventilation port or exhaust fan is provided at the top of the rack’s rear panel to expel any accumulated heat.

- If the S-1608 or S-0816 is mounted in a portable rack, remove both the front and rear rack covers before use to ensure that the S-1608’s or S-0816’s front and rear panels remain unobstructed.

•

—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.

•

—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.)

• You can expand your system by using an additional S-0816 at a “split” location. This will deliver the 16 inputs from the Stage (Master) unit but will not allow any return channels. The additional S-0816 will require the use of the S-4000-SP or a standard gigabit Ethernet switching hub in order to switch the Ethernet data. Your split location S-0816 REAC mode must be set to Split (SP).

Setting the REAC Mode

If you set the REAC mode of a split location S-0816 as a REAC Slave device (S), the system will not work properly. It creates a communication problem in the REAC routing system. In order to maintain correct REAC routing, perform the following:

1. Turn off the power of all REAC devices according to “Powering Off” (Page 46).

2. Set the [REAC MODE] switches of all REAC devices properly.

3. Turn on the power of all REAC devices again according to “Powering Up” (Page 46).

See Chapter 7 for information on setting up Split REAC devices with a REAC Splitter S-4000-SP or Ethernet switching hub.

fig.6-16.eps

The [REAC MODE] switch on the S-1608/S-0816 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-1608, set the [REAC MODE] switch to M.

2. On the S-0816, 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.

REAC Cable Length Extension

If necessary, the REAC cable length can be extended by placing a REAC Splitter S-4000-SP or Ethernet switching hub in-line to refresh the REAC signal. Multiple splitters and 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 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.

REAC Connection Notes

• The REAC connection can be “hot-swapped”—that is, connections can be made when the S1608 and S-0816 units are powered on.

• In some circumstances, this connection may result in brief noise at the system’s audio outputs. To avoid this, turn down the volume and/or power off any devices connected to the S-1608/S-

0816. Or, connect/disconnect the REAC cable while [MUTE ALL OUTPUTS] is held.

• If the REAC cable is disconnected while [MUTE ALL OUTPUTS] is held, it’s possible that one of the S-1608 or S-0816 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 (REAC 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-1608 or S-0816.

fig.6-23.eps

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

The S-4000R can be connected to either the S-1608 or S-0816. 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-1608 and S-0816 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-1608 and S-0816 units in the S-1608/ S-0816 System. See Chapter 7 for more information.

The S-1608’s (S-0816’s) audio inputs are used to send source audio signals to the S-0816’s (S-1608’s) audio outputs.

Connect the output of balanced audio devices (microphones, instrument outputs, etc.) to the balanced audio inputs on the S-1608 (S-0816) 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:

GROUND

HOT

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

fig.6-35.eps

Ordinarily, when plugging and unplugging devices to and from the audio inputs and outputs on the S-1608 and S-0816 units, the volume of all devices connected to the S-1608/S-0816 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-1608/S-0816 System’s audio outputs.

1. On the S-1608 or S-0816 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 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-1608 and S-0816 units to the audio inputs of other devices, always turn down the volume or turn off the power on the receiving devices.

Indicator

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 S1608/S-0816 units will remain in a muted state when [MUTE ALL OUTPUTS] is released. If this occurs, use the following procedure:

6—Using the S-1608/S-0816 System

Input Pad

fig.6-42.eps

Each S-1608/S-0816 system’s input channel features a switchable input pad. When the pad is engaged, the channel’s input sensitivity is reduced by 20 dB.

Use the pad when connecting a “hot” audio source to an S-1608/S0816 system’s 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:

1. Select the desired channel (1–24) with the [CHANNEL] knob.

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.

Stereo Link

The Stereo Link function allows you to link odd/even adjacent S-1608/S-0816 system’s 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-1608 or S-0816.

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:

Channels 7 and 8 linked: Channels 23 and 24 linked:

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.

Advanced Use

Using Two S-4000R Units in a Single S-1608/S-0816 System

As discussed in Chapter 6, the S-4000R can be connected to either the S-1608 or S-0816. 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-1608/S-0816 System at the location of either unit.

fig.7-01.eps

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-1608/S-0816 system’s 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.

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 REAC splitter S-4000-SP or standard Ethernet hardware.

By integrating a REAC splitter S-4000-SP or an Ethernet switching hub into the REAC system, source signals from REAC Master unit can be split to multiple additional REAC Split 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.

56 S-1608/S-0816 Digital Snake Owner’s Manual

7—Advanced Use

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-1608/S-0816 System is extremely easy. Simply add a REAC splitter or a switching hub and an S-0816 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-1608, they can be split as many times as you wish with absolutely no loss in quality.

What You’ll Need

To split the S-1608’s 16 channels of input audio, you’ll need:

• a REAC splitter S-4000-SP or an Ethernet switching hub with enough ports to connect each REAC device.

• an additional S-0816 unit for each split destination.

• REAC cable SC-W100S or Cat5e 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.

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 Master/Slave device’s 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.)

Setting the [REAC MODE] Switches

See Page 38 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-1608, set the [REAC MODE] switch to M.

2. On the primary S-0816 (usually at the FOH position), set the [REAC MODE] switch to S.

3. On each S-0816 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.

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)

• 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 up to 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).

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.)

Appendices

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.
