Meridian 565 Installation Manual page 61

Sound not clear
If speech sounds muffled in a system with a centre speaker,
check that sound is coming from the centre as there may be a
connection problem. In a digital or Meridian feed to the centre
you may have set it up to be right instead of left so that it is
playing a subwoofer signal.
If speech sounds muffled in a system with no centre speaker,
you may have selected a layout that expects one. See
Specifying the speaker layout, page 22.
Centre not working
There may be a connection problem.
In a digital or Meridian feed to the centre, you may have set it
up to be right instead of left, and therefore it may be playing a
subwoofer signal.
There is a hiss when starting DTS
LaserDiscs
The DTS audio stream is indistinguishable from a PCM audio
stream; the 565 takes 30 msec to identify the encoding, during
which a hiss is heard.
With non-video DTS sources you can add a 30 msec delay to
avoid this. However, with video sources the delay would
cause a noticeable sync problem, so the hiss is unavoidable.
