DIY 12v trigger output ..

So , this thing doesn’t have a 12v trigger out ..
I’m gonna make one using one of the USB ports ....

We’ll see if it works ......

    Just tried it .....
    Works perfect !
    The 851 USB ports output power....

    Cut the end off a USB cable , stripped the sheath off ....
    The green and white are data , the red and black are power , black being ground.
    Spliced the usb power wires to a mono 3.5mm jack cable and presto , 851 now has a 12v trigger out !! Snip the green/white wires , wrap rest with electrical tape or whatever to make pretty ...

    Turns the amp on and off !

    It would probably work with anything , TV’s etc , that has a powered USB port ....

    I thought the power lines on USB were 5V (??).

    PS Get yourself some heatshrink tubing to "finish" it like a pro! ;) I can send you some if you don't have any, are loath to purchase some and if you live in the US and want to PM me an address :)

    That would be great !
    I’ll pm ya .....

    USB ports ARE typically 5v - that’s the usb standard ....
    Most trigger inputs will work with less than 12v ..... usually anywhere from 5-12 v...
    There is no standard for trigger inputs from what I gather .

    All I know is it works perfectly !

    Can't beat empiricism! I "assumed" that was what was goin' on (i.e., voltage promiscuity on the part of the trigger, so to speak). :)

    Just in case anyone else is interested...
    Personally , I think this is a potentially great problem solver for some ...
    I know it was for me ...
    I figured it out after I found this , knowing a USB port had power ....

    well, it's like frequency agile, you know?
    5 VDC... 12VDC... whatever it takes to turn 'er on, you know?
