CARE OF YOUR SUBWOOFER
Your Infinity subwoofer cabinet is finished with a heavy-duty, high-quality vinyl which requires
very little maintenance. Keep the cabinet clean by dusting it occasionally with a damp cloth or
use a good quality furniture polish to maintain its original luster. (When using aerosol products,
always spray the cloth, not the speaker, to prevent any of the product from drifting onto the
electronics of the unit.)
FEEDBACK
If the bass seems boomy, or you notice a rumbling sound when listening to record albums, the
cause may be acoustic feedback. This means that low-frequency vibrations from your speakers
are reaching the turntable. To help isolate the turntable from these vibrations, place the
turntable on a heavy, solid support, as far away as possible from the subwoofer. If you continue
to experience difficulties after experimenting with placement, consult your Infinity dealer.
CD players are also susceptible to acoustic feedback and should be placed on solid supports to
isolate them acoustically. Another method to isolate the CD player is to place it on four
isolation feet available at your local dealer.
IN CASE OF TROUBLE WITH
YOUR SUBWOOFER
If the subwoofer sound is distorted, stops playing or otherwise seems to be malfunctioning, first
determine if the problem is in the subwoofer or the wiring and/or other audio components. If
the problem also affects the satellite speakers, the cause is most likely in your electronics. If it is
only noticed in the subwoofer, make sure that all connecting cables are correct and in proper
working condition. Make sure the subwoofer is plugged in and turned on.
If everything seems to be in good working order and the subwoofer still malfunctions,
DO NOT ATTEMPT ANY REPAIRS! Contact your Infinity dealer and get the name of the
authorized Infinity service center near you. If there is no facility near you, contact Infinity's
Customer Service Department at (800)553-3332, or write:
