Mods to circuit board in an LED par64

hey, while it is not exactly recommended to go in and change things as it voids your warranty should ur led ever need repair but have u tried adjusting the sensitivity knob to low? um i have not see na schematic on the pc board so i dunno im sure you could get a hold of tech support and ask for one but you never know. peace! jingles.

I bought these second hand, so there's no warranty. Unfortunately they don't have a sensitivity knob - only one for 'speed' which controls their pre-programmed change pattern and has no effect when they're switched to 'music'. What I'll do if I got the schematic is replace the relevant resistor with a pot, to make a sensitivity control.

wait what brand are these? and which type of led are you using? like p64 or punch led or what? peace! jingles.

They are no-name Par64s. I'm guessing they're Chinese imports, but there's nothing on them to suggest even that. The PCB markings are normal, English ones, but definitely no make.

oh well then if they are not adj or elation then go ahead and rip em apart man!! lol ya then i don't even know if the schematic for the adj leds will be the same so ur gon just have to go off ur own luck and tech skills! lol. best wishes. jingles.

You could simply program scenes in a DMX controller that has sound response and then make a chase sequence. Since you'd have more control over the timing of changes, you can gain the control back that you want from those LED Par64's.

That would be more of a smart thing to do. But hey, if you feel adventurous with a soldering iron, you'd be best using a pot to take care of it. You shouldn't need a resistor if the pot is done properly inline with the circuit. You might want a PCB or other board of sorts to more easily run leads to and help facilitate mounting, but if the pot is big enough, that might not even be a proble. However, color matching might be touchy unless in master/slave mode.
