Change xlr speaker outs to 1/4" speaker outs?
This vibration technologies sl140 is a solid state slave amp. There are two xlr (microphone) cable speaker outs that I want to switch to 1/4" jacks.
The 1/4" jacks have three pins on the back.
The xlr jacks are also connected by three wires to the circuit board.
The xlr jacks also come out of the amp as 8 ohm and 16 ohm and are wired accordingly within(3 wires).
I understand I only need two wires (+ and -) to wire up the 1/4" jacks and I'm handy with a voltmeter to determine what pins are center or not but the xlrs and internal wiring of the amp are throwing me.
My thoughts are two of the wires are the same (either hot or ground) and the lone wire will be the other. Determining which is hot or ground in the amp is a problem.
The wires are colored and I am planning on opening up to see the board and what's what but was kind of hoping for someone who may know a thing or two to throw a bone my way. I was hoping it would be quite easy to do.
(Couldn't find a schematic, info or an active number for this company.)
Is dit een goede vraag?
joe, since this seems to be a somewhat different piece of hardware, it might be beneficial to post a couple of images on here so we can see what you see.:-)
Thanks very much for the background and help...I just got into the amp...which is just the slave amp...it has an input on the front with a gain as well but no distortion effect I think...it is grey. ;)
Here's some pics just in case as I wouldn't want to miswire this thing...it seems the two yellow are continuous with the screws in the back plate, not the plate itself, as well as the casing of the xlr outputs.
It appears that I have ground(?) to pin 1 and 2 on both xlrs but they head out to different spots on the board near one another and the 8ohm tap has it's grounds separated.
Pin 3 seems to go into the other side of the board and is common on both 8 and 16 taps.
