POWER.
REAC EMBEDDED POWER is a technology for using Cat5e cables to supply power as well as REAC audio signals.

power source.
This unit automatically detects whether a REAC device connected to a REAC port from 3 to 10 is compatible
with REAC EMBEDDED POWER. If the REAC device is found to be compatible with REAC EMBEDDED POWER,
this unit automatically supplies power to it. Power is not supplied if the device is not compatible.
