wiring emergency

[psy]

im about to knock up a couple of balanced XLR cables to connect my pioneer djm600 to my amp but I have noticed an eccentricity in the pinouts of the djm600.

 

on pretty much everything else I look at the pin outs are 1 gnd, 2 hot and 3 cold but the djm has it down as 1 gnd, 2 cold and 3 hot.

 

my question is do I connect the pins at both sides the same ie. the usual 1 gnd, 2 hot and 3 cold or do I connect the pins on the amp side the normal way but connect the pins on the djm side the pioneer way in other words should I be connecting hot to hot and cold to cold as according to the spec on each piece of equiment like this (amp side) pin2 - (mixer side) pin 3, (amp side) pin3 - (mixer side) pin2 ?

 

im actually doing the job at the minute so I would appreciate any help as soon as anbody is able.

As long as both ends are balanced, and both cables are the same, a conventional straight-thru cable should be fine. Nobody will notice that your sound is back-to-front.

As long as your amplifier has balanced inputs - just wire your cable straight pin to pin, screen pin 1 to pin 1, pin 2 to 2 and pin 3 to pin 3.

Your cable will then be standard - and can be used anywhere, with no danger of 'spurious polarity reversals'.......

cheers guys.

 

whaddya mean by back to front though?

Although there are arguments saying that its a good idea to have everything in phase, and as such wire up two small 20cm cables (Ideally with some bright coloured flex, I use orange) To invert the phase of the output. As a result the main outputs are in the same phase as any secondary outputs/booth outputs, if there is any leak FOH or you are half way in between there would be some totally crazy phase issues.

so youre saying its better to make a straight through cable then even if the pin outs are reversed on the mixer? am I right. it doesnt matter to me which way I make the cables as im only ever going to be using them for this one job so I just want the best way and the one thats likely to cause less issues irregardless of which way that is.

 

cheers btw

POLARITY

Sorry about that, got a little carried away. Maybe you want the booth outputs the oposite POLARITY, there are arguments for and against this. The same can sometimes apply to FOH and monitors.

 

I'd just wire them straight 1 to 1 2 to 2 3 to 3 etc, especially if it's just for 1 job. Unless you are using other outputs to go to speakers in the same stacks of course. It's unlikely you're going to be doing that.

ooo... did I mention it's POLARITY

I wouldnt worry about it. So long as pin 1 is always ground then I dont think anyone will really notice. Electrically it will be fine.

[Rob_Beech]

Providing they are both identical to eachother of course.

the only other speaker connected is a powered speaker run directly from the booth output as a monitor also I run from the rec output but thats not to speakers just a laptop soundcard for recording

[Rob_Beech]

Then you won't have any trouble.

actually just one last question. all the audio outputs on the mixer are 1v except I have noticed the XLR outs are 1.23v

 

would I be better off keeping the sensitivity switch on the amp at 1v or putting it up to the 1.44v setting?

[Rob_Beech]

leave it as it is for now, and see how you go. If you find that you're overloading the amp easily then switch it. At 1.44v setting and only 1.23 from the desk, you'll ensure you won't send the amp above its rated power, but you'll also not be able to get the most out of the amp.

ok cheers this is gonna sound really stupid though how do I know if im overloading the amp?

 

sorry for the idiot questions but im giving my new gear its first run out on saturday and I want to try and get the best from it without wrecking it in front of 100+ people ;)
