Unless someone here just happens to work for BA and has the schematic we won't be able to help with that. Fixya is a volenteer thing so there is a fairly varied tech base represented here so you never know.

I've looked at that board (I think) and the ic you are looking at is a 16QFP?
I'm not 100% sure but I think it was a atmel part.

You may end up having to pull it to actually id it. The schematics are going to be rather unlikly to get too far out of the factory.

Well I searched high and low, but couldn't find anything at all.... usually, though a KB controller, seldom fail? Usually, it is the Interface, that has been "Spiked" or a Power Supply problem. Use you 'scope and feed a signal in. and trace it to where it stops... You could also use a signal generator, say an old radio, and use a capacitor to feed in the signal, to a handy point, and use an old, earphone, with Probes attached to it.. Also check, you power supply, is that OK, 'cause if it's NOT nothing else can be..

The Bacini Acoustica will not charge. It works only when the charger is plugged in. Could the battery be "dead"? If dead, what type do I need to replace?


It requires a 12V 7.2ah battery F1 terminal. Its located on the bottom of the tower just under the charger input. You need a phillips screwdriver to remove the cover plate which has 6 screws. If you own this Bacini Acoustica Tower Speaker, please publish the wall charger information found on the back of the charger. I need to replace that.

No sound


1. check the power, is the LED indicator light when you turn on the power?
2. assuming the power is ok, unplug the phone plug from the computer, plug it to an ipod or any mp3 player's phone jack, still no sound? here are the possible causes:
a) broken internal copper conductor from the phone plug, b) busted amplifier chip
if you have basic electronics knowledge, these multimedia speakers are easy to repair, otherwise replace the whole unit. ;-)

I have an S-air wieless stereo and when I try to add additional speakers (wall jack type) the main unit will only pair with one speaker at a time - it unpairs the others. I can't get all of them to play at...


The unit probably does this so that you don't have an impedance mismatch which would mess up the internal amplifier...most home stereos will do this to protect the amplifier...

I have Bacini Acoustica portable Wireless Indoor/Outdoor Music Box I lost the manual and I don't know how to hook it up to the back of my new HD TV can you help me???


You plug the transmitter power adapter into the back of the speaker then you use the dual rca cable to plug into the left and right outlets on the tv and into the adapter. Mine came with the pig tail cord.
