3049.0. "Foot-switch wiring question" by ASABET::blasta.mlo.dec.com::pelkey (life aint for the squeamis) Thu Mar 02 1995 10:51

here's a question on foot switch wiring..

I've got a couple of Yamaha Gx12 series amps..

I run em in stereo..  Since they've both got dual channels
I can use a foot switch to change channels.

My question.. Is it doable to wire 2 leads (standard coax with 1/4
jacks to the amps.) off one foot switch so I can use one switch
to activate both channel selects ?

I've not cut into the switch yet,,, I can't see a reason
why it wouldn't work, but then again, I'm not really sure about
this wiring stuff and I'd hate to hose the foot switch if for
some reason it won't work!

	Should work, and you shouldn't even need coax to do it. ("Coax" being sheilded and all. This isn't an input signal you're dealing with.) -- Sam
3049.2	Try a Y cord.	MILKWY::JACQUES	Vintage taste, reissue budget	`Thu Mar 02 1995 13:56`	5
	You should be able to accomplish this without hacking up a footswitch. All you need is a y-cable. Plug the end of the footswitch cable into the y and feed both amps. Give it a try. Mark

	Mark: RE: Y cable.. No that didn't work already tried... It seemed to put one of the amps in limbo (no channel selected..) I'm fairly sure the "Y" and all cabels in question we're working.... any hints? /r
3049.5	Use a DPDT type switch	SALEM::DACUNHA		`Fri Mar 03 1995 13:43`	5
	You should wire it as two independant circuits, activated by a single lever (footswitch) ideally using a single DPDT switch. These may be difficult to find in a footswitch type case.

	re: Two independant Circuits. Yea, that's sort of where I'm at with this.. I'll give it a try this week.. thanks...
