1.0 Setting Up

1.1 Applications

To assist in planning the installation, Figures 2 through 9
(pages 9–14) illustrate typical configurations with recom-
mended wiring guidelines.
Note: The normalized SPL estimate given for each configura-
tion is based on the FreeSpace
measured at 1W @ 1 m. Actual SPL measurements may vary
depending upon ceiling height, loudspeaker spacing, and
cable losses (see Section 3.2, Wiring considerations).
Note: There may be instances when an installation requires an
odd number of loudspeakers, that is, 3, 5, or 7 per channel.
This expansion module makes these possible.
The 5– and the 7–loudspeaker configurations will yield output
variances between the loudspeakers connected to the odd
loudspeaker channel. The recommended wiring configurations
are shown in the following figures.

1.2 Loudspeaker placement

Consult the Bose
Installer's Guide for complete loudspeaker placement guide-
lines.

1.3 Polarity

For correct phasing between loudspeakers, connect them with
consistent polarity. While incorrect phasing does no physical
harm, it diminishes the bass response.
• Connect the (–) at the expansion module loudspeaker outputs
to the (–) at the loudspeaker terminals.
• Connect the (+) at the expansion module loudspeaker outputs
to the (+) at the loudspeaker terminals.
