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.
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.
5—S-4000 System Overview • Straight-through cables should be used when an Ethernet switching hub is integrated into the system for cable length extension or split applications. (We’ll discuss switching hubs a little later.) Ethernet connection standards recommend using straight-through cables to connect devices to the ports on a switching hub, and crossover cables when connecting hub-to-hub.
5—S-4000 System Overview About Ethernet Switching Hubs An Ethernet switching hub—sometimes referred to simply as a “switch”—is an interface that allows multiple devices (called “nodes” in Ethernet lingo) to communicate with each other in an Ethernet network. The switching hub has multiple ports with RJ45 receptacles, and each network device is connected to one of these ports.
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.
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: S-4000 Digital Snake Owner’s Manual...
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.
• 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.
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.
Page 42
Use the following procedure to remove and reinstall the S-4000S’s rack-mount brackets for recessed rack-mounting. Turn off the power on all equipment and disconnect all cables from the S-4000S unit. Remove only the screws shown in the following diagram (12 screws total), and detach the rack- mount bracket from one side of the unit as shown.
Page 43
6—Using the S-4000 System Recessed Rack-Mounting: S-4000H Use the following procedure to remove and reinstall the S-4000H’s rack-mount brackets for recessed rack-mounting. Turn off the power on all equipment and disconnect all cables from the S-4000H unit. Remove only the screws shown in the following diagram (6 screws on each side, 12 screws total), and detach the rack-mount brackets from the sides of the unit as shown.
6—Using the S-4000 System DB-25 Connector Guard (S-4000H Only) 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.
6—Using the S-4000 System Rack-Mounting the S-4000R The S-4000R Remote Controller is designed for handheld or desktop use. If desired, it can be rack- mounted by installing the included rack-mount brackets. Use the following procedure to install the rack-mount brackets on the S-4000R. Disconnect the RS-232C cable from the S-4000R unit.
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 EtherCon- type connectors.
6—Using the S-4000 System Installing the Included Ferrite Cores on Ethernet Cables Four ferrite cores are included with the S-4000 System for installation on Ethernet cables. Install a ferrite core on the Ethernet cable near the RJ45 plug that will be connected to a REAC port. Use the following procedure to install a ferrite core on an Ethernet cable.
6—Using the S-4000 System 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.
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.
6—Using the S-4000 System 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). ��������������������� �������...
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. �������...
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.)
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.
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.
������������������� ����� ��������������� The S-4000S’s balanced audio I/O is provided on XLR-type jacks. The wiring diagram for these jacks is shown in the following illustration. Make connections after first checking the wiring diagrams of other equipment you intend to connect.
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.
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).
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.
Turn on any devices connected to the S-4000S and S-4000H units’ audio inputs. 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.
6—Using the S-4000 System 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.
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. S-4000 Digital Snake Owner’s Manual...
��������� System’s audio outputs. 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. When you have finished making input connections to the unit, release MUTE ALL OUTPUTS.
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.
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 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.
6—Using the S-4000 System Setting the Preamp Gain Use the following procedure to set the preamp gain on an S-4000S input channel: Select the desired channel (1-32) with the CHANNEL knob. Send an input signal to the selected channel. While viewing the input level on the LED input meter, use the GAIN knob to adjust the preamp gain to the desired level.
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.
6—Using the S-4000 System Stereo Link The Stereo Link function allows you to link odd/even adjacent S-4000S input channel pairs (1/2, 3/4, etc.). When channels are linked, gain and pad settings made on one channel of the linked pair will be duplicated on the other.
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.
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.
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.
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.
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.
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: •...
An S-4000R can be connected to the REMOTE connector on a Split REAC device. However, it can only be used for system and signal level monitoring—adjustment of S-4000S inputs is not possible. (If you need to adjust the signal level coming from a Split device’s outputs, use the input trim controls on the receiving device.)
MIDI 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).
Additionally, the units provide error indicators that let you know whenever a potentially serious problem is detected in the system.
