No sound from subwoofer
If your subwoofer does not work on your altec lansing speakers,
more than likely you blew the subwoofer amplifier board.
I have an ADA-885 system and bought it brand new back in
November 2000 and has been flawlessly operating great up
until this past month when my subwoofer went out but my
"satellite" speakers kept working. After disassembling the
subwoofer box I first noticed that the subwoofer amplifier
board is seperate from the rest of the grouped boards for
the dolby and satellite speakers. The subwoofer box is
designed to use the air from the subwoofer to actually
cool the amplifier boards inside the unit, great feature
until your subwoofer goes out, that is when your main
amp will more than likely fail soon after the sub amp
fails, as it uses the air from the subwoofer to keep the
amps cool. I know this might be an older post but
hopefully I can put it in the right category to hopefully
be able to help someone out in the future.
You can test the ohms of the speaker with a multi
tester. It's a dual voice coil speaker, 6 ohms each.
Well my system is broke and needs another
subwoofer amplifier board so if anybody reads
this and has this subwoofer, I need my sub amp
fixed ! or if you have the subwoofer unit maybe
and nothing else to go with it but the subwoofer
lights up, give me a jingle, I'd buy it from you !!
