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.
