Insufficient volume from a device
connected to the output jacks
●
You’re using a cable that contains a built-in resistor.
Insufficient volume from a device
connected to the INPUT jacks
●
You’re using a cable that contains a built-in resistor.
Use a connection cable that does not contain a resistor.

The REAC port provide a REAC indicator that shows the REAC
communications status.
The following table shows the meaning of the REAC indicator
status:
If REAC connection is unsuccessful, check the following points:
• Make sure that all REAC devices are powered on.
• Check the Cat5e cable connections.
• Make sure that the Cat5e cables are not damaged.
•
Verify that you’re using the appropriate type of cables. (See
“About REAC” (p. 11)
• If you’re using a switching hub, is it operating?
• If you’re using a switching hub, is it connected correctly?
•
If you’re using a switching hub, does it have the correct
specifications? (See “Requirements for switching hubs” (p. 120)
