Side-Axis Speakers
The DMC-1 has two side-axis channels which are
matrixed and derived from the left and right front
channels, so they are available in stereo as well
as surround modes. Use the OSD SPEAKER SIZE
menu to turn the SIDE-AXIS channels ON or OFF
(see pages 56-57).
In the diagram to the left, typical placement of
the side-axis speakers is depicted by the speakers
that appear to be “suspended” where walls are in
the room. Another appears above the window
on the left side of the drawing. Wherever you
position them, place these speakers along the
side walls, close to the fronts. You can also angle
them in towards your listening position for better results. You should not use a surround or eect
speaker (such as a dipole) for side axis speakers. Direct radiating speakers will give the best result
without interfering with the clarity and presence of the main speakers in the front left, center, and
right sides.
The Surround Speakers
Place each surround speaker to be an equal
distance away from your central listening
position and keep them at least one or two
feet above ear level.
The diagram to the left shows the use of dipole
surround speakers. These are usually positioned
to the side of your listening position. They
radiate forwards and backwards and have a
quiet null zone (the “apex” of the triangular
shape) which should point towards the listener.
The overall eect is that you cannot hear the
direct sound from the surround speakers
because they don’t directly radiate into the listening space. Most manufacturers of dipole speakers
intended for use as an eects or surround speaker have excellent details on optimum positioning
for the best overall results based on the application.
Conventional surround speakers can be placed behind the listener, on the rear walls or the side walls
or in the ceiling (as the diagram indicates). Adjust the angle so they do not point directly at the listener
but cause reections from the sidewalls, oor, or the ceiling. Avoiding direct aim at the listening
positions will give the eect of broadening the rear soundstage so that you cannot distinguish the
sound as coming from a small box on the wall but from a larger area behind you.
