5 Troubleshooting
Problem: Hub’s Power indicator does not turn on.
Procedure: Check that the hub is plugged into a live outlet. After you
have ensured that it is not a power issue, check that you have a hot
signal going into the inputs. If a signal is not detected, the hub will go
into a sleep mode after 5 minutes to comply with Energy Star.
Problem: Amplifier Node’s power indicator does not turn on.
Procedure: First check to make sure that the power indicator is lit on
the hub, if not then see the corresponding Troubleshooting entry. If this
does not resolve the issue, then double-check the Cat5 cable going
from the hub to the amplifier node. Replace this cable if possible. If this
is not the issue, then ensure that you are not stringing too many nodes
on a line. Refer to section 3.2.2 for more information on this.
Problem: Amplifier Node is outputting no audio.
Procedure: First check that the signal indicator on the hub is lit and the
volume control is at a reasonable level on the hub. Next, to rule out a
cabling issue, check that the power indicator is lit on the amplifier
node. If this does not resolve the issue then refer to section 3.2.2 to
ensure that the DIP switches are correctly configured on the node. If all
of the channel selection switches are in the “up” position, then this is
most likely the issue. Refer to section 3.2.2for the proper settings.
Problem: Amplifier Node is outputting weak audio
Procedure: First check the Level knob on the hub to make sure it is at
a reasonable level. Next, check the DIP switches on the front of the
amplifier node to see what the gain is set at. If both switches are in the
“up” position and you still have a weak output, check to make sure
that you are not stringing too many nodes on a line. Refer to section
3.2.2 for more information on this.
