Infinity Alpha 25

ES

Check the speakers for playback first by setting the system
volume control to a minimum level, and then by applying power to
your audio system. Play a favorite music or video segment and
increase the system volume control to a comfortable level.

NOTE:

You should hear balanced audio reproduction across the

entire frequency spectrum. If not, check all wiring connections or
consult the authorized Infinity dealer from whom you purchased
the system for more help.

When the Infinity Alpha 25

ES

speakers are used as part of a 

Dolby Digital or DTS

®

multichannel home theater system with a

powered subwoofer, it is recommended that you set your receiver/
processor speaker mode to “small” or “high-pass” for all
channels connected to an Infinity Alpha 25

ES

. In addition, some

receivers/processors allow you to adjust the high-pass frequency
for the “small” or “high-pass” setting. If your receiver/processor
has this capability, it is recommended that you set the high-
pass frequency to the lowest setting above 70Hz. Consult your
receiver/processor manual for more information about these
adjustments.

The placement and setup instructions in this manual are written
in general terms to cover most typical installations. We realize
that each room is different and that your specific installation may
require some modification to these guidelines. You can be sure
that if you need to install the speakers outside the guidelines in
the manual, they will still deliver excellent sound with any music
or film soundtrack.

Feel free to experiment with the Surround Mode Selector Switch
to determine the best settings in your room with your system.
