Hello,
I have an Acoustimass 9 that I want to connect to a Pioneer 5.1 amplifier. Is it possible? can you help me in building an adapter to the bose din? (attached picture).
Best regards,
Lorenzo

Lorenzo, I have just got a schematic for the amp. I am trying to utilise it for a sub. Are you looking at just using it for a sub, or what are your intentions.
There is a couple of issues that I can see to start. ie the amp is turned on my an external voltage (from controller) looking at bypassing that at the mo. Second issue is volume controll of the amp which comes from serial data, however this is also bypassable with some effort. I will let you know how my project progresses |

Thanks Mark!
Now I finally got my hands on the system!
Unfortunately it seems like the sub is AM9P...
The prior owner had a really crappy repair-job on the input-cable (the 8-pin DIN-cable). I cant understand how he have connected this? It seems that:
top of 3,5mm is connected to pin 7
mid of the 3,5mm is connected to pin 3
base of the 3.5mm is connected to pin 6
ground on the rca:s is pin 5 and pin 2
Tip of rca:s is pin 4 and pin 1
Is this correct? (pinouts according to the "maleside" of this: http://freespace.virgin.net/tom.baldwin/DIN8-pinout.gif )
Feels that I have to start with checking all the cables before I start digging into the sub
With best regards
Olof

Olof,
I will refer to the 3.5mm jack sections as "tip","middle" and "shield". The "tip" should be connected to pin 6, this carries serial data to the sub. The "middle" carries the 10-12v turn-on voltage to control the power on the sub and should connect to pin 1. The "shield" is ground and should be connected to pin 7
Pins 2 and 4 are the signal inputs for the Left and Right channels respectively. Pins 3 and 5 are the grounds for the two channels. A mixup of these two sets, 2&3 or 4&5 is no big deal because they drive a differential amp within the sub (and there is a "differential" regardless of which pin is ground and which is signal. The important ones are of course the ones for serial Data and turn-on voltage. Make sure they are correct. And by the way, the reference you found for the male 8-pin DIN connector is correct.
Sorry for pasting someone elses thread on here but it may help. |
