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 dealer.
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 speakers, so repowering the unit will ensure that it
is out of standby.
Drive units move when the speaker is
switched on or off
This is normal as the speaker active electronics settle.
Sound is odd or mono
❍ Check the channel selector switches on both loudspeakers
are correctly set.
