i had a Altec Lansing Technologies model ACS45, a cable connector 5 pins male from small speaker (treble) to big one (base)was broken, can some one help me to have a schematics or wiring for it Thank

Have you tried asking Altec Lansing for the info?

I have internal wiring for ASC45.1 (using digital volume control).

Did any one have the schematic of it.

hi,
you can find the datasheets of the I.C. on http://www.alldatasheet.com/ but only this for schematic I tried to answer altec but don't have response at this time (. This can perhaps help you help you, so if you have no ON/OFF and NO UP/DOWN volume it seams it is the PT2256 is the cause of this. I have this prob on mine, I change the 4013 and the 4011 but the problem persist. If you desolde the pin 6 & 7, the ON/OFF restart but you don't have the volume UP/DOWN. If you don't have the sound with this you can try to shunt pin 2 & 3 and pin 14 & 15, in this case you retrieve the sound but without volume adjustement. So you must find the PT2256 and change it to restore the normal working.
Hope this help you. ) and others have the same prob.

I have an Altec Lansing ACS45; much thanks about the pinout. Note that for my system, the Volume UP and DOWN are reversed as compared to your arrangement. Otherwise it works beautifully.

One question: the ACS45 does not seem to shut off when the volume UP and DOWN are pressed simultaneously (my logic is that i connect vol UP+DN+Ground all together). any fault in my logic? or is the ACS45 (don't know about the ACS45.1 at all) simply limited in this way?

One more device saved from the landfill :-).

sorry to dig up an old topic but I have the ACS45.1 system an it turns on and has sound but you cant adjust the volume control up or down. It's not in the cable and no reply from altec for awhile.. does anyone have a circuit digram for the main board or know what the problem part is?? ic..transistor..????

Cheers
