Troubleshooting
Unit goes silent when played hard
The subwoofer has a temperature sensing system on board, which prevents
overheating of the electronics. The sound will continue when the speaker
has cooled.
There is radio interference
The subwoofer is a digital audio and computing device which has been
designed to very high standards of electromagnetic compatibility.
If this equipment does cause or suffer from interference to/from radio or
television reception then the following measures should be tried:
•
Reorient the receiving aerial (or antenna) or route the antenna cable of
the receiver as far as possible from the subwoofer and its cabling.
•
Ensure that the receiver uses well-screened antenna cable.
•
Relocate the receiver with respect to the subwoofer.
•
Connect the receiver and this product to different AC outlets.
•
If the problem persists contact your dealer.
Drive units move when the speaker is switched on or
off
This is normal as the speaker active electronics settle.
Subwoofer stays in standby
This indicates a problem with the Comms setup:
•
Check the comms cabling; see Connecting the subwoofer to other
equipment, page 17.
•
Reselect the source and increase or decrease the volume.
Subwoofer output sounds odd and lacking in bass
when connected to a Meridian digital processor
A digital audio connection carries two channels. Make sure that you are
picking up the right one. For example, if you have connected the
subwoofer to the Centre/Sub output of the processor, make sure that the
digital input switch is set to 2 to pick up the sub signal. If it is set to 1 you
will hear the signal intended for the centre channel.
If the speaker on a channel is confi gured as Small its signal will not contain
any bass, and a subwoofer set to pick up that channel will therefore not
output much of a signal. Check the subwoofer defi nitions in the
confi guration and change as necessary.
