Speaker Sets A and B

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.

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.

Corner

Subwoofer (SKW-940)

The subwoofer handles the bass sounds of the LFE (Low-Frequency Effects) channel. In general, a

1/3 wall

good bass sound can be obtained

length

by installing the subwoofer in a front corner, or at one-third the way along the wall, as shown.

Speaker Set A: Main 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.

Speaker Set B: Sub Room

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.
