Mk114 - niedervoltlichtorgel / low voltage light organ

I have buy the LOW VOLTAGE LIGHT ORGAN. Connect is 12V DC input and output 12V DC LED’s. Problem is, that the LED’s glow, I have to turn the sound up very loud. Is there anything I can do?

Thanks a lot


Unit is equipped with an opto-coupler at the input, so you need at least 1.7V at the input.

Hmm… that makes sense.
On the website of Vellman I find the construction manual, but I miss a circuit diagram.
Is this available? Probably, it would be very helpful.

Diagram has been mailed to your address.

Great. Thank you! :smiley:
