Hi i am in Australia I just wanted to double check.
I was told the Marantz 7005 that i have a cant connect it to a XPR-5 because the pins are different configuration. If so can't i simply change the positive and negative on the amp/speaker side
thanks

It seems hard to believe that they aren't using standard balanced connectors.

the issue isn't the speaker side it's the connection between the processor and amp, your processor uses a uk/euro pin out whilst emo amps use the US variant pin out..
I told you this over the phone earlier today if you don't believe what I tell you walk into the place you brought the marantz from they will tell you the same exact thing even emo tech will do the same..
green i would of thought that too sadly it isn't the case, it's widely known over on avs not sure which version the NZders get here in australia we get euro/uk pin lay out

suit yourself if you're currently using xlrs in your current configuration see if you can a convertor plug or get someone to build you a set of cables suitable us-uk/euro xlr...
either that or run rca-rca.....

You can have some made or make them yourself. That is what I have heard of guys doing.

Micheledlp, how long is your run from pre to amp? If less than 15-20 ft., why don't you simply use RCA interconnects?

Never heard this before with XLR's.
Anyone have a link to where this is the case?
I have here a Modwright Pre, XSP-1 and a XPA-200 and an Italian amp with XLRs and they all seem to be interchangeable between them all. Also a Nad M51 and a Musical Fidelity phono stage and they work on both Preamps with XLR.
ADDED:
I did just read this on another forum

Re: XLR: American vs European pinouts?
Postby Bob Lee on Fri Feb 25, 2011 1:52 pm
There is no "American" or "European" XLR pinout. The AES adopted a standard of pin 2 = + (or "hot") and pin 3 = - (or "cold") back in 1992 (http://www.aes.org/publications/standar ... m?docID=19). Before that, it was haphazard, with some manufacturers using pin 2 + polarity and others using pin 3 +. It's possible that more European manufacturers used one than the other and more American manufacturers used the opposite (perhaps a point of confusion for Marantz); I only know that there was quite a mix (QSC has always used pin 2 +, but in the early 90s I worked for another US power amp manufacturer that used pin 3 +), and probably the overall number tilted a bit in favor of pin 2. At the September 1990 AES Convention in Los Angeles, the LA section spoofed that lack of decisive coordination by handing out "XLR Polarity Indicator" spinner cards; the possible results were "Pin 2 +," "Pin 3 +," and "Spin again." :lol:
Fortunately, for any processor, cable, or other device with balanced XLR input and XLR output, there is no polarity issue as long as it is the same from in to out. For other audio devices that convert between balanced and unbalanced, such as microphones, power amps, DI boxes, etc., polarity doesn't matter much as long unless you're using multiple ones (i.e., more than one amp) with different polarities.

I thought the American 3 pin = hot configuration has gone obsolete and all modern equipment now uses 1=ground, 2=hot, and 3=cold. 2 and 3 used to be wired differently depending on the country the equipment was intended for. But I thought that the 2=hot has become an international standard. Call Emo.
I'm not even sure it would make a difference to you but I'm not 100% on that. Forum member DYohn may have some input on this.

Forum member DYohn may have some input on this. geebo is right. This is an OBSOLETE problem, that is only an issue when matching (much) older equipment to new. Shouldn't have any problems with equipment manufactured over the last couple decades... |

So worst case, if pins 2 & 3 were reversed for one component on all channels, wouldn't then all signals just be 180 out of phase and hence in-phase with each other? Sounds like it's a moot point anyway as it's no longer an issue

Okay, let's put this to bed once and for all,... I did find this interesting explanation online though that states that this has been an obsolete issue for quite some time now. See this, (and scroll down to the part titled "Technical usage information"): en.wikipedia.org/wiki/XLR_connectorIt states in part: Prior to the introduction of this ("European") standard, the wiring of pins 2 and 3 varied. The pin 2 "hot" and pin 3 "cold" convention was typically used by European and Japanese equipment manufacturers, but American companies used pin 3 "hot" and pin 2 "cold". This caused problems when interconnecting equipment with unbalanced connections. The pin 3 "hot" convention is now obsolete but is still found on vintage equipment. Pin 1 has always been ground and/or shield if the cable is shielded, and many connectors connect it internally to the connector shell or case. So it appears that only when "vintage" equipment is paired with new equipment that it may be an issue. Otherwise the "European XLR Standard" has been the universal standard for quite some time now, and it shouldn’t be an issue with any equipment manufactured over the last couple decades. And I'd bet its what Emo has been using for their amps and XLR interconnects for a long long time now... |

I'm drumming up and old thread, but this was on my mind today. When making a custom cable from the G3P center sub to feed a MiniDSP 2x4 Balanced, what is the actual pin out of the XLR socket? I was planning to confirm this is correct before I start messing with my subs again today. I'm afraid I've had these wrong. Im trying to understand if it is the Emotiva processors or just the amps that are not following industry standard.
