I recently acquired a Boston Digital Model BA735 Speaker. It is in mint condition. Power supply included. My question has to do with the 'control' connector, which resembles an "S" video connector.
The speaker is 7.5" H X 6" wide. It has an amp inside that I would like to use. Sending audio into the RCA connector, lights up the 'activity' LED. No output due to the fact it needs to be 'controlled' somehow. Can anyone tell me how it's controlled? I haven't started tearing it apart yet, YET... ha ha

tnx

That had two satellite speakers, one with a control.  The second speaker connected to the first (the one with the controller).

If you don't have the satellite speakers, you'd have to follow the wiring to see which are the Power pair, the Volume control and then the left and right channel.

Sounds like all you have is the sub-woofer.

Thanks Jim.
Sorry about the multiple posts. I asked my 'Elmers' question from the main page. I previewed it, and when I hit 'post', I got an error message (3X) HA HA
When I went to 'forums', then I saw the 3 postings. Strange.
Anyway, I must have one of the satelites, I went back today to get the sub-woofer, which was MUCH larger and VERY heavy, and it was gone. The place I buy my speakers is a Sherrif's Youth Ranch 'outlet', kinda like an indoor flea market. LOTS of the stuff is ex-evidence, put up for sale to benefit the Boy's Ranch. Kind of a win-win.....
The circuit board is very dense and loaded with SMT devices. I was hoping that there was a way to turn on the amp and speaker by sending a control signal (VDC, ground, whatever) via that small 'control' connector. I really don't want to toss the amp and just use the speaker and enclosure........

tnx

 These are computer speakers and are meant to work with the subwoofer. Looks like you only have 1 of 3 required assemblies.

The sub enclosure contains the amp for the subwoofer and the line level audio and control circuits to feed the other speakers

 I would try to find a sub as it will be a mess trying to get this to play.

I have one of these, and it is still in use. As others have noted, it sounds like your have bass speaker only. There are two other speakers that also go with this (left and right speakers). The speakers were sold with Gateway PC's around 2000.

There is a further catch, these require a digital output from a Sound Blaster card that was also specifically made for Gateway. Mine still work fine, but with out the missing bits you may just have some interesting parts.
