hello, i'm new to this section and this website. i am currently debunking the PCB of an Altec Lansing VS2621, or at least what is remaining of it...

i have the main subwoofer but i don't have the 2 speakers. i had it because the composite connector was broken and speakers were stolen. the guy let it to me because otherwise he would throw it away.

Though, i know nearly why each component's role is done for.

if anyone needs the schematic, i have it.
v1 :  alteclansing_vs2621.pdf ( 47.77k ) Number of downloads: 309

v2 :  altec_lansingvs2621_2.pdf ( 86.72k ) Number of downloads: 231

Besides, i need heavily backlighted normal and reverse pictures of the pcb of the speakers.

this is my last hope, no pictures of the pcb can be found on internet. my project is to transform that audio kit into an active subwoofer. my audio system misses a .1 speaker that system is 7.1 and i have already the 7 speakers .

from the signals written on the main board, i guess there is:
_ button on/off
_ volume potentiometer,
_ jack 3.5 stereo connector
_ a pcb/board

the idea is to give vs2621 owners a schematic in order to repair theirs (and also for my own project).

add me to the club

Hi all,
anyone knows what causing my vs4121 sound intermittent?

like how?

chances are your cable is dying or your volume pots are old and needs cleaning

I usually advice spraying with contact cleaner and twist the volume back and forth to clean it but most of the time vs4121 is so tightly covered the spray couldn't get into the electronics

ATP3 still alive n kickin....!!!

Hello everyone!

I have:
MX5021 Black since 2006
MX5021 White since 2008
FX6021 Silver since 2018 (yesterday) (now cleaning it from prev. owner, yuck!)

Sources: iPod 5.5G 80 GB (like new), E-MU 1820m, etc.

Hi guys, I am selling VS 3151 (5.1 Surround), And also ATP 3, both are in superb condition, under utilized, if anyone interested, please drop me an offer. Thanks !

post pictures of it, so i can help you a bit to know which component is likely to be responsible of your problem. i hope you still visit this forum :/

Waseh 2017 post. Haha. Sold it away few months back as it is. Didnt manage to fix it anyway

thanks for the reply anyways hope for me that i'll find another one who has that model. i think i'll do it
the schematics that i've posted were done by following each copper track to each component.
i wrote down everything i could. but there are some parts i don't understand (the big part in the middle of the sheet).

if anyone needs some advice about repairing some cable... i can help.

Hello guys,

The reason this thread still alive because all love their Altec speakers.. Good quality build!!

Recently, I retrieved an old Altec Lancing ACS48 from my storeroom and it's dead.. Thinking to repair it and called Ban Leong just now (previously Altec distributor and SC) but they said no longer repair it..

Anyone have any contacts to repair PC speakers?? (techinian/shop/hifi shop contacts and etc...) I"ve been asking around but none can help.. Hope Lowyat can help...

Thanks guys..

Please help out this brother, I too a fan of Altec Lansing speaker, if someone knows a reputable speaker technician please do share.

Hi all, i recently use back my speaker that i keep for over 20 years, it still work like before. sound quite good actually for an old 2 decades product. I like it by the way, wish altec lansing come out with a model similar to this and refine everything that they can. It is ACS 45.

if you feel confident enough to unscrew and solder/desolder some pins or else, send me the pictures i will tell you how to do it and on which parts of boards

Anyone here want to let go ADA 885? Even spoilt. PM me plz.

Hi, I have VS 3251 (5.1 Channel) and also ATP 30 (2.1) up for sale, both are in superb and working conditions. Interested ?

Still available?

yup, both are still available.

having problems controlling the volume on my ACS 45.1, the buttons sometimes not really functioning well. Any owner that face the same issue? any solution?
