    Can a non-switched power supply be used in place of a switched one?

    The PC power supply hack included grounding the green wire so the power supply is always on.

    Can a non-switched power supply be used in place of a switched one?

    Well, I do have a car battery in the basement hooked to my backup sump pump but it's registering 13.2V and I am a little uneasy about sending too much voltage into the keyboard. Seems like there is a risk no matter which way I go.

    Can a non-switched power supply be used in place of a switched one?

    As mentioned I got the computer power supply hack to work with the keyboard, but then on a Korg forum someone made this comment regarding the power supply: It's always been my understanding that power supplies technically do not put out amperage and the connected device uses only as much as it...

    Can a non-switched power supply be used in place of a switched one?

    Thank you for your replies. Right now I am looking into a tutorial on hacking a PC power supply for 12V. It is my understanding that the amperage output is plenty for the keyboard. Does that sound like it would work? - - - Updated - - - Well, I got the PC power supply hacked, splicing...

    PCB internal microphone to line level?

    Thanks for the reply. My mixer has a direct out for each channel so I can send only the kick drum channel to the strobe controller. I will give your suggestion a shot and see what happens. I would imagine that I could also use the potentiometer to find the optimum resistance and then replace...

    PCB internal microphone to line level?

    Hi, I don't know if this is the right place to ask this question or not but I'll try... I play in a band and I would like to connect a sound activated strobe light controller to a direct line out of my mixer for the kick drum, so the strobe triggers when the kick drum is played. The strobe...
