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 effect 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 po-
sition and keep them at least one or two feet
above ear level.
The diagram to the left shows the use of di-
pole surround speakers. These are usually
positioned to the side of your listening posi-
tion. 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 effect is that you
cannot hear the direct sound from the sur-
round speakers because they don’t directly radiate into the listening space. Most manufactur-
ers of dipole speakers intended for use as an effects 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 reflections from the sidewalls, floor, or the ceiling. Avoiding
direct aim at the listening positions will give the effect 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.
