5 Troubleshooting
This chapter gives step-by-step troubleshooting procedures, with
suggested solutions, to problems that may occur with the Systemline
Modular System.
Golden rule
Always check cable connections
Speaker will not come out of
standby. The red standby indicator
blinks continuously
The amplifi er is short-circuited or
thermally overloaded so the speaker has
switched into self-protection mode.
The most likely cause of the fault is a
short-circuited CAT5 speaker lead to
the left passive speaker, either due to a
damaged cable or crossed connections.
Check the wiring and correct the fault with
the system powered down. Power up the
system again and check the speaker has
reset and the fault is no longer present.
Note:
The speaker must be powered
down and back up again to reset the self-
protection feature.
Speaker will not come out of
standby. Red standby indicator
remains illuminated
This may be because the speaker and
remote control or keypad have been set
to two different infra-red addresses. Reset
the infra-red addresses as described in
Changing module addresses
, page 18, and
try again.
Speaker switches on, with the
blue indicator illuminated, but
there is no sound
If others zones are working this probably
indicates a break or fault in the wiring
between this zone and the audio
distribution hub.
If no zones are working this probably
indicates a fault in the wiring between the
audio distribution hub and the line-level
input module.
If the speaker has a connection for a local
source, try connecting a local source to
the speaker. If this works it indicates that
the fault is in the wiring between the
speaker and the main system.
Testing sub-zones
If a main zone works, but its sub-zone
doesn’t work, this indicates a fault
between the main zone and the sub-zone.
Sound breaks up and becomes
unstable at high volume settings
If all zones in the system are affected this
is probably due to a faulty power supply,
or a bad connection between the power
supply and the audio distribution hub or
power input module.
• Try an alternative power supply.
• Ensure that you are using a 130W power
supply and not a 45W power supply at the
audio distribution hub.
If only one zone is affected this is most
likely to be due to inadequate power to
the affected speaker.
• Check that the cable length to the affected
speaker does not exceed 50m.
• Check that there is not a loose connection
on the power supply connections to the
affected speaker.
• Try connecting a local 45W power supply
to the affected speaker.
• If the zone is a sub-zone, check that there
is a local 45W power supply for the
sub-zone, and that it is switched on and
connected correctly.
