If your surround processor or preamplifier
does not include a Calibration option, listen to
familiar source materials and adjust the gain
until the bass sounds solid and deep, but not
boomy or intrusive.
Setting the phase (polarity)
The PHASE switch allows you to invert the
phase (reverse the polarity) of the signal to the
subwoofer.
If your digital surround processor includes
a Calibration option and you can adjust the
phase there, set the switch to the + position.
If the bass sounds hollow or phasey, and does
not image correctly, change the position of the
PHASE switch. If in doubt, select the position
that gives the most bass.
When you have completed configuration of
the C52, replace the acrylic cover provided, to
avoid unintentional adjustment.
TROUBLESHOOTING
Unit goes silent when played hard
The unit 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 C52 is
switched on or off
This is normal as the electronics settle.
Subwoofer stays in standby
This indicates a problem with the Comms
setup:
• Checkthecommscabling
• 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 configured 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 definitions in the configuration
and change as necessary.
