I am working on a Light Organ circuit designed to take Speaker level. I would like it to take Mic level. I was thinking a Transformer would do the trick. Any help or suggestions is appreciated. I would like something designed into the circuit itself rather than something external.
Mic level to speaker level (High Level)

Your subject line seems to ask the opposite of what you want!?
Transformers are the classic way of doing it when hardwired, but I never liked that approach, as it interferes with the sound.
If you want stuff designed into your circuit, you sort of have to post your circuit
My best suggestion is to use a mic as input device, that way you get the light to react to people clapping/stomping as well - makes for a more inclusive approach (I'm assuming you're gonna use it for parties and such).
If you only want the sound itself to manipulate the light, a line level feed from your amplifier would still be better than tampering with the speaker signal. Add a voltage divider if needed.
It reads to me as exactly what I want, my signal is at Mic Level, the Circuit wants to see Speaker level,

So...connect it to the speakers.
There are no speakers
Then you need an amplifier.
Or you can tell us about the circuit and we can modify it (as other people already said).
The poster for a Yoga class doesn't really amplify your information.
A step up Transformer is what I am looking to do most likely
Yes as I said before I am trying to avoid an external amplifier
Seren already gave me the info I need actually!

I don't think that's going to work. You need about 100 to 1 voltage gain. A milliwatt transformer trying to drive an input that is expected to see an 8 ohm driver...I can't find one.
I don't think so!
I read your post as if you wanted to do a classic (seventies) hookup from speaker output to the light organ, which typically needs lower input amplitudes.
My bad for reading you wrong!
You may be able to use a microphone transformer, they are very expensive (although a low quality type may be found - don't ask me where though), but this is probably a very kludgy way of doing it.
You have been asked a couple of times to post a schematic, I'll ask as well and if your hesitance to do so is that you don't have it, at least supply as much info about it as you have, like make/model and some focused photos of it's circuit.
It's quite likely that what you have could be changed to take mic level, as there's likely a simple voltage divider (or even a transformer), in your existing input stage.
I haven't followed this very closely but couldn't you make use of the preamp on this page plus one of the small power amps at bottom of page? http://www.mcmelectronics.com/prod/...UPjdD2A.1&utm_referrer=www.mcmelectronics.com
Mike preamps do not drive to speaker level. . .
It's mic not "Mike" ..
