Notes to Observe in Using the S-4000 System
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.
