Impedance Transformer and sound amplifier

Hi

I have some third part circuit to make some lights dancing with sound, but it usually doesn't work. So I have tried to make it, but I have a problem with the impedance transformet to attach the circuito to mi Hi-Fi amplifier. It have 50+50W rms output with 6 omh impedance, and i use a 6-2k ohm impedance transformer, but the output voltaje in secundary is tooooo high (if amplifier outputs 35V, the impedance transformer output 350 V or more).

I would like to know how to calculate the correct impedance I need to attach the circuit to my HI-FI sound amplifier, or how to reduce the voltaje without damagin the amplifier (of course!!). I don't found any information about it in internet, and my electronic knowledge isn't enough for it xD

Any help will be good!

thaks!

reverse transformer

Run the transformer the other way around so it steps the voltage down. To further reduce the transformer output voltage, use a resistor divider. You want the tap across the amplifier output to be a high impedance so it does not waste power.

I am assuming that you are using the audio to trigger the lamp drivers.

Yes it's to control the lamps with the music.
where I should connect the voltaje divider ? In primary or secondary coil? Primary is connected to the HIFI system, and secondary to the control circtuit of lamps.

I undestand how a voltaje transformer works, but impedance one... i can't understand totally. Well.. It's a half time proyect.. really that kind of proyects that one does form a mounth to other xDD A neverending proyect.. hehe

Thanks. CU
