Maintaining Your 901
If your 901 speakers have a painted surface, clean with a soft damp cloth. If necessary, use
®
a mild detergent such as dish soap. If the speakers have a wood veneer finish, clean them
with wood furniture polish. You may vacuum the speaker grille panels carefully, if necessary.
Do not use any sprays near the system. Do not use any solvents, chemicals, or cleaning
solutions containing alcohol, ammonia, or abrasives. Do not allow liquids to spill into any
openings.
If you have a problem with your 901 Series VI speakers or 901 active equalizer, turn off the re-
ceiver or amplifier before you proceed. Then check all the connections between the speakers,
receiver, and active equalizer. Correct any wiring problems before you follow the guidelines
below. Problems are more likely to originate with equipment other than speakers, so you may
also want to refer to your receiver or other component owner's guides.
What to do
• Do not switch the wires; this could damage a speaker. Turn off the amplifier and disconnect
the defective speaker wire at the amplifier. Reconnect it to the other channel. If the speaker
now plays correctly, the problem is not in the speaker or wiring.
• Connect the speakers to another receiver or amplifier that is known to be operating
properly. If the speakers now play correctly, the problem is not in the speakers.
Note that the tonal balance of the 901 speakers will be incorrect if the 901 active equalizer
is not being used with this second receiver or amplifier.
• Check to be certain that the 901 active equalizer is in the circuit. Review the Playing
your speakers section of this guide on page 14.
• Try turning down the volume. If the distortion goes away you may be using an insufficiently
powered receiver or amplifier.
• Bypass the equalizer to see if the system operates properly without it. (Speakers will not
have any highs or lows.) Check to see that all connections are correct and that none of
the cables is defective.
• Contact your authorized Bose
a factory authorized agency or by the Bose factory. Bose Corporation will make every
effort to remedy any problem within the terms of the warranty.
