The S-4000-SP is a REAC splitter for use with the RSS S-4000 Digital Snake System.
Use of this REAC splitter enables you to do the following:
• It permits you to extend REAC cables in lengths of 100 meters.
• It allows you to split the master REAC device’s input audio to a split REAC device.
In addition, the S-4000-SP also has the following features:
• The S-4000-SP is made up of two independent 5 port splitters with independent
power supplies. These two splitters can be used independently as dedicated
splitters for the REAC device’s MAIN port and BACKUP port. This provides a fully
redundant REAC connection system.
• Two independent internal power supplies furnish power to each of the two internal
splitters, enabling uninterrupted use in the event the power happens to cut out in
one of the power supplies or if there is some other sort of power interruption.

Notes to Observe in Using the S-4000 System
Use and Handling of REAC Systems
The REAC cables used in digital snake systems employ computer network
technology to enable transmission of multichannel audio signals.
In very rare cases, however, noise may be generated when these systems are used in
certain environments. If noise is present, check the following points.
About REAC Cables
As REAC cables use computer network technology, you should pay attention to the
following points regarding wiring with network cables.
• Ensure that cables used for REAC connections conform to the Cat5e (Ethernet
Category 5) standard.
• No single cable should be longer than 100 meters.
• Do not use cables with cut or torn coverings.
• Do not subject cables to undue stress.
• Do not wind or bend cables such that the radius of the turn is 25 mm or less, and do
not double cables over.
• Do not bind cables tightly into bundles.
Notes to Observe When Producing REAC Cables
If you are making your own REAC cables, note the following precautions in addition
to those above.
• Use plugs (RJ-45) conforming to high reliability standards.
• Do not separate the wires (twisted pairs) within the cables.

Advantages and Precautions to Note
When Connecting the Split Device with MAIN and BACKUP
As shown in the figure below, using the S-4000-SP for REAC connections with MAIN and BACKUP allows one
splitter to ensure continued REAC transmissions even if the other splitter fails.
However, REAC transmissions will not be switched if there is a failure in the MAIN REAC cable connected to the
split device. Accordingly, no audio will be output from the split device under such circumstances.
This is due to the fact that REAC split devices are designed exclusively for the reception of signals only, so even
if a split unit should detect an error, it cannot communicate this back to the Master Device.
■
Example of Malfunction
If cable or is interrupted, the system will automatically switch to the BACKUP REAC system.
However, if there is a failure of the MAIN REAC cable going to a Split Device, cable , then the system will not
automatically switch to the BACKUP REAC system, cables , and .
■
Reestablishing Transmission
Carry out the following steps in the event a transmission failure to the split device prevents the transmission of
audio to the Split device.
1.
Disconnect the active REAC cable from the REAC connector in either the MASTER or SLAVE device.
The active REAC connector will have a blinking indicator light.
To activate REAC transmission using the BACKUP cable system, you can disconnect the MAIN cable from
either the MAIN device, cable , the MAIN connector on the S-4000-SP, cables or , or the MAIN
connector on the SLAVE device, cable . Once you do this, the system will automatically switch to the
BACKUP REAC system and use cables , and . Audio will be restored to all SPLIT devices.
2.
Check the REAC cable in which the failure occurred.
