4 pin xlr question
« on: July 27, 2004, 07:44:36 PM »
Why are many power cables made with 4 pin xlr's?  Could you use a three pin xlr?  They sell the three pin connectors at my local music store.  I would rather not order them if there is no need.
Thanks,
Ed

4-pins are the standard for battery connectors mainly

3-pin connectors are the standard for high-quality mic cables

so its really sticking w/ the standard :)

you can use whatever you want. it's not mandatory to use a 4pin. 4 pin connectors provides flexibility to run 2 different voltages like the Echocharge systems.

if you're building a custom power supply, i wouldn't even use a 3pin xlr. i like the Molex connectors myself. they are cheap, versatile and works well.

Yet, so many folks use the 4-pins that for that one time you are at a show in the OTS and your battery dies, do you really think that the spare the guy behind you has is a 4-pin or a molex?

I'd go with what has become the standard.

i'm not disagreeing with you, but speaking from personal experience, i don't think anyone will have a spare 24v system if i ever ran out of juice for my pre.

from looks of it, majority of folks here use their own DIY setups with all kinds of pin assignments, although a standard is in place.  just think of all the different voltage sources that are out there now: 4.5v, 5v, 6v, 7.2v, 9.2v, 12v, etc. etc.

i'll stick to my own design because it works best for me.

A good reason not to use 3 pin xlrs -- you wouldn't want to accidently plug your mics directly into a battery/power supply by mistake

quoted for truth

no way I would use a 3pin xlr for anything power related.
