I have just dug out my old but working fine Laser FX sound to light effect.
This needs a mono audio input either line or speaker and its input impedance seems to be around 50K
My Denon DM37DAB has a mono output for a sub woofer I guess.
Can I connect to this device using that? would any harm come to the Denon?
I could add a resistor in the line etc.
Thanks for advice
