Meridian America 541 - Manual (Page 63)

Troubleshooting and maintenance
57
Communication is not working
between the surround controller and
other Meridian products
❍ Check that all products are interconnected using the correct
comms leads.
❍ If the installation includes 200 Series or 600 Series units,
check that all 500 Series units are set to 200 mode.
The sound is not clear
❍ If speech sounds muffled in a system with a centre
loudspeaker check that sound is coming from the centre, as
there may be a connection problem.
❍ If speech sounds muffled in a system with no centre
loudspeaker you may have selected a layout that expects one;
see Configuring the surround controller, page 35.
The picture quality is poor
❍ Check that you are using suitable quality cables with good
connectors.
❍ Check that there is not a ground-loop between any of the
components connected to the 541.
Remember that reception of broadcast or cable signals can be
significantly degraded by cross-modulation in the RF domain. It
is unwise to attempt to cascade and mix several video sources
(eg LaserDisc, VCR, etc) to an antenna system.
There are problems using the SCART
connectors
❍ Check that the SCART leads you are using have the correct
pins; see SCART connectors, page 31.
❍ Check that you are not making the connections to both the
SCART and phono connectors.
❍ If the TV is not displaying a picture check that the TV is
switched to the AV input, or Function Select is working.
❍ If you are watching an RGB source your TV may need to be
switched away from it, or the RGB source turned off.
There is no on-screen display (OSD)
❍ Check that you are feeding a composite video signal on either
SCART or phono for the current source.
