Troubleshooting
Red power indicator on front panel not
lit
Check the following:
• The power switch on the front panel of the DSP420
is turned on.
If the DSP420 will still not illuminate, check any fuses
in your power supply and the fuse on the front panel
of the DSP420. If these are all intact, contact your
retailer.
Red power indicator on front panel is
flashing
This normally indicates that the DSP420 has
overheated and that it has shut down to cool down. If
the DSP420 is cold, it may indicate a fault.
• Allow the DSP420 to cool down. It should then
operate normally.
Green lock indicator will not light
The green indicator lights when the product is out of
standby and is locked to a digital source.
• Check that the digital audio input is wired correctly
and that it is connected to an active source of SPDIF.
• Check that the COMMS is wired correctly and that
the Meridian system is out of standby.
Note: The DSP420 boots to an out of standby state,
unlike other Meridian DSP loudspeakers, so repowering
the unit will ensure that it is out of standby.
Drive units move when the loudspeaker
is switched on or off
This is normal as the loudspeaker's active electronics
settle.
Sound is odd or mono
• Check the channel selector switches on both
loudspeakers are correctly set.
Only the master loudspeaker plays
• Check the RJ45 cable is connected correctly.
Centre not working
• Check that the channel switch is set to LEFT/
CENTRE.
There is radio interference
The DSP420 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 DSP420 and its cabling.
• Ensure that the receiver uses well-screened antenna
cable.
• Relocate the receiver with respect to the DSP420.
• Connect the receiver and this product to different AC
outlets.
• If the problem persists contact your retailer.
Configuring the DSP420 does not have
any effect
Make sure that you are configuring the DSP420 used
as the master digital loudspeaker in the system. This
determines the configuration of all digital loudspeakers
in the system.
