Hi Good day! Im planning to rebuild my Philips powered subwoofer. i just want to ask based on the 8 pins(RB909), how can wire the power on switch and how can i put the input signal? thanks

 

You have not shown enough of the circuit to really tell.

 

Where did that connector originally connect to?

 

Probably linking pins 1,2 together , but you need to post the full circuit.

apology for the late reply. i think i attached the wrong diagram. diagram is from the main unit of philips component. 9pins(D) from the main unit is connecting to the subwoofer. component is already dead. i just want to rebuild the subwoofer so i can connect it to my computer. can you help how to power the subwoofer unit and how to wire input signal thanks.

connected to philips component. subwoofer is just part of the component.

What we really need is the circuit of the subwoofer' Otherwise the best I can deliver is a good guess, which may not be good enough. But based on what I see you still need a power supply that delivers both the -23 volts and the +5 volts. So please see about posting the complete circuit of the subwoofer component. And don't dispose of the main unit yet because it appears that you will need a power supply.

Hi MisterBill, i sent new diagram. pins are above letter D of the diagram. thanks.

Unfortunately I don't see the new diagram. And I examined the previous ly posted one and I don't see anything on it that looks like a power supply. So there is a bit of a problem someplace. If you still have the complete system, I suggest that you follow the mains connection into it and it should go to the power supply. You will need at least some portion of that supply to power the amplifier. ALSO, you may be able to find a circuit diagram someplace on the web. I have about 20% luck in finding them on the web.
