Pin 3 = Left Line In +

Pin 4 = Right Line In +

Pin 5 = Left/Right line In - (Common Ground)

If you want a volume control you need to put one on the inputs. You will buy buy a stereo volume control or potentiometer.

Logitech z3 wiring


I have a logitech z3 subwoofer with a mini-DIN-9 connector socket. It also has a volume control and 110V power cord. As best as i could trace the circuit, and using the TDA7377 stereo bridge amplifier chip datasheet, the pinout for the mini-DIN is as follows (untested):
1: L in (to vol.)
2: R in (to vol.)
3: Power (12V from transformer)
4: Standby (5V to play, 0.05mA; 0V to standby)
5: L out
6: R out
7: Ground
8: Ground
9: Ground

Connecting 3 to 4 with a large resistance (~20K ohms) should enable speaker. Pins 1 and 2 might be swapped; pins 5 and 8 might be swapped. Mini-DIN socket pin holes are numbered right to left, bottom row to top row:
9 8 7
6 5 4 3
2 1

My woofer is not working as if there is a short somewere it comes on then when moved it goes back off


sounds like the contact points on your 9 pin DIN connector are corroded. If carefully cleaning each pin sounds like too much work, a search on ebay for a male 9 pin mini-din might bring you joy. But THAT solution requires some soldering.

A creative speaker SBS A200 connector pin was damaged. we need to connect that cable directly into the board.so we need that pin details.


Hi, I hope this helps,

Pins look like this: (Top view, not copper side)
1 2 3 4 5
6 7 8 9

1 = Thin white wire from thick white cable (Left input)
2 = Gray (Speaker out)
3 = Orange (+V return from volume unit to bass unit)
4 = Not connected
5 = Thin Red wire from thick red wire (Right input)
6 = Blue (+V power from bass unit to volume unit)
7 = Black (GND - if socket removed, solder 3 socket shield holes to each other or solder black wire directly leftmost hole)
8 = Not connected
9 = Shield copper from thick red wire

Shield copper from thick wire : Solder to GND or Left unconnected

An i get the diagram for the ON OFF switch and volume control? mine is damaged i like to fix it


-"Can i get the diagram for the ON OFF switch and volume control?". I built mine based on a schematic generated by tracing the printed circuit board of a working unit. Some component values are non-standard but I just used the nearest standard values. The ON/OFF switch was also replaced by a toggle switch because the original is an integral part of the volume control. The 9-pin mini DIN connector presented the greatest hurdle in my part of the world but got lucky cannibalizing a discarded Strobe Pro scanner. The completed unit worked as charm. The schematic can be found here: http://i1192.photobucket.com/albums/aa327/aguinart/Creative5200.jpg.
