Hello All
I know powerlink has a preamped line out in the cable for left and right
i also know that there is a pin for speaker on.
Does anyone know what voltage is used for the on signal?
im hopnig 12 volt so it can triggar a seperate amp to switch on.

It`s only 4-5 volt on PIN 4.

It's 5 V ideed.
But you can covert it very easy from 12v to 5v with a resistance and a zener diode.

This worked perfectly for me.
Hay sorry other way round I want to use the powerlink 5v to triggar a 12 v trigger on a amp
Would this work is .83mamp enough current?

Persoanally I would not recomend the dc convertor, the powerlink signal will not be designed to power loads, which is what this will present itself as.
What I would do is build a little box with a switched 12v signal coming from a separate power supply. You could make it nice n neat and it would still be very simple!

Perhaps more to the point, I don't think it would even work. For example in 9500, the Powerlink pin 4 signal comes from a CMOS port pin through a 1K resistor. If you load it by for example 2 mA only, the output voltage will have dropped below 3 volts. I'm sure it can't even supply enough current for the converter to start up, let alone produce any useable output.

Hi there
so i need to build a small peice of electronics that will receive a very low signal and then use a external power supply to switch a 12v feed on.
this should not be to difficult, thanks all

Yes, at the minimum it could be a single transistor (and a base resistor and a protection diode) that would be enough to drive a relay, for example. There's probably an example somewhere in the archives already.
Hi,
i have been using one of these for s few years now to control a 12v trigger signal (from a 12v plug top power supply) to power amplifiers from the 5v powerlink output of my Beosound 9000.
