Enjoying Home Theater
You can use two sets of speakers with the AV receiver: speaker set A and speaker set B .
Speaker set A should be used in your main listening room for up to 7.1-channel playback.
*While speaker set B is on, speaker set A is reduced to 5.1-channel playback.
Speaker set B can be used in another room and offers 2-channel stereo playback.
*Only analog input sources are output by speaker set B.

Speaker Set A: Main Room
Front left and right speakers (SKF-940F)
These output the overall sound. Their role in a home theater is to pro-
vide a solid anchor for the sound image. They should be positioned
facing the listener at about ear level, and equally spaced from the TV.
Angle them inward.
Center speaker (SKC-940C)
This speaker enhances the front
left and right speakers, making
sound movements distinct and
providing a full sound image. For
movies it’s used mainly for dialog.
Position it close to your TV facing
forward at about ear level, or at
the same height as the front left
and right speakers.
Subwoofer (SKW-940)
The subwoofer handles the bass
sounds of the LFE (Low-Frequency
Effects) channel. In general, a
good bass sound can be obtained
by installing the subwoofer in a
front corner, or at one-third the way
along the wall, as shown.
Speaker Set B: Sub Room
Surround left and right speakers
(SKM-940S)
These speakers are used for precise
sound positioning and to add realistic
ambience. Position them at the sides
of the listener, or slightly behind, about
2–3 feet (60–100 cm) above ear level.
Ideally they should be equally spaced
from the listener.
Surround back left and right speakers (SKB-940)
These speakers further enhance the realism of surround
sound and improve sound localization behind the listener.
Position them behind the listener about 2–3 feet (60–100 cm)
above ear level.
THX recommends that they be placed as close as possible in
order to make advantage of their proprietary ASA (Advanced
Speaker Array) technology. If this condition is not possible,
adjust the SB Spc (Surround Back Spacing) setting via the
THX Audio (see page 51).
* While speaker set B is on, these speakers output no sound.
