About MultiPole Technology
The MultiPole capability of your S200 and S300 lets
you better enjoy different types of surround programs
at their best. The descriptions that follow assume you
will position your surround speakers to the left and
right of the listening area and not directly behind it.
Dipole Mode: This mode provides everyone in the
listening space with enveloping surround. Most sound
is projected sideways (to the front and rear of the
room), while little is directed at the listeners (see
Dipole in the
Multipole Modes diagram). As a result,
the sound is well mixed with room reflections, following
longer paths. In Dipole mode, a listener can be closer
to one surround speaker than the other and still hear
both surround speakers. This characteristic makes it
ideal for smaller rooms, where a listener may be closer
to one surround speaker than the other.
Dipole mode is ideal for use with synthesized surround
decoding modes; the choices on your decoder
labeled “Hall,” “Theater,” “Church,” or similar names.
Also, use it for Dolby Surround programs (the prede-
cessor to Dolby Digital and the format supported by
stereo TV programs with surround encoding). Dolby
Surround has a monaural surround channel which is
split between the two surround speakers. Dipole
mode’s dispersion pattern prevents this channel from
“collapsing” towards the closer surround speaker.
Bipole Mode: This mode “fills in the middle”
compared to Dipole mode. Each surround speaker
projects approximately equal amounts of sound to the
sides and at the listening area (see Bipole in the
Multipole Modes diagram). This makes it easier to
hear effects occurring
between the left and right
surround speakers. Dolby Digital’s separate left and
right rear channels make this possible. The more
Dolby Digital program material you listen to, the more
you will benefit from Bipole mode. In larger listening
spaces, Bipole mode can even rival Dipole mode on
non-Dolby Digital program sources.
Monopole Mode (S300 only): In this mode, the
S300 substitutes a dedicated, front panel-mounted,
direct-radiating two-way system for the front and rear
surround drivers. This precise system directs sound
mostly at the listening area, like the front three speak-
ers (see
Monopole in the Multipole Modes diagram).
For centrally located listeners, this mode provides the
most precise sonic imaging, both front-to-rear and
side-to-side. Use it for Dolby Digital programs with
abundant multichannel sound effects.
