I’m considering a fix/mod for my djx700 mixer, but i lack the information to continue, so i hope someone here could help…
My effects on/off button broke the other day, so i decided that i would replace it with an arcade button.
But the problem is, that the base of the button is too deep to fit on the board(second pic). Now i really don’t want to use a spacer, because the button would stick out of the mixer too much, so i need to know if it is safe to make a hole in the mixer motherboard (the board pic with the white circle).
As far as i can see there are no other connections going trough the board on the spot i need to drill other than the led and the effect button itself…
There is at least the LED traces that run there and the hole would be very very close to the driver IC’s of the led.
Take a good look at some of the POT’s. If you add up the amount of ttracks you see on both sides, and they are less than the number of solder pads, it’s a multilayer board. It’s not an airtight way of determining it though.
as boarderbas says, drilling into a PCB “can” be dangerous, as many manufacturers use multilayer boards.
why not find a place on the mixer top that has space and relocate it there ?
BTW there’s a multitude of other styled buttons that could replace the broken one, an arcade button for this job is overkill, checkout eBay for non latching momentary switches Pardon Our Interruption...
