Hi Guys
i was wondering if anybody can help me with a querie, as i am new to emo gear, ive got the xsp-1 gen 2 pre-amp & dr2 gen3 connected using XLRs, all is good no problems, i have a network player connected to the xlr balanced input of the xsp-1 using xlrs, no major problems, but as i said im new to the emo gear only had 1 week, so still tweaking & tinkering with various settings and in such, i found on my network player the option on balanced outs (hot2 or hot 3) ive been running at hot pin 2 but couldnt find what the correct config is for the xsp-1 or what the consequence of running this might be if wrong, any advise would be welcome, many thanks. T.K.P.

Emotiva use the American standard for XLR, commonly called hot pin 2.
Cheers

Hello,
I have a Yamaha CX-A5100 that is showing in the manual that the XLR output is 1 - ground 2 - hot 3 - cold. But, the last time I connected an Emotiva amp to it, the speaker tests all failed polarity. So, I swapped the speaker connections. How does this happen if Emotiva is using this American standard? Would not Yamaha use a different standard?
Thanks.

It's an non issue. It involves absolute phasing which is a *bleep* anyway because many devices have an even number of phase inversion amplifying stages and many have even numbers of phase inversion stages. So phase will always be an issue.

But, the last time I connected an Emotiva amp to it, the speaker tests all failed polarity. So, I swapped the speaker connections. How does this happen if Emotiva is using this American standard? Would not Yamaha use a different standard? Thanks. EIA Standard RS-297-A formalized the universal XLR3 pinout standard back in 1970. For reasons known only to Emotiva, all of their amplifiers use the long obsoleted “American” standard (pin 3 hot/pin 2 cold). This only becomes an issue “if” you are mixing Emotiva amplifiers with any other brand that uses the official EIA standard (which logically should be all of them). If you find yourself in this situation, the easiest solution is to reverse the polarity of the speaker wires at the back of the Emotiva amp. Since all of Emotiva’s preamplifiers and source components use the proper EIA pinout standard, my hope is that they will also bring their future generations of amplifiers into universal compliance. |

AudioHTIT thanks, this is what I had remembered. The big mystery to my is why they do their pre-amps and processors one way, and the amps another. Perhaps as some have suggested it matters not in the big scheme of things, still curious though.

Sometime back I posted a Secrets article which compared the design of the EMO XPA-1 to the ATI 6002. As I rember 😳 from the article the EMO is an “inverting” design and the ATI a “non-inverting” design. So could be ? EMO uses the European standard XLR to compensate for a phase inversion. Keith? Lonnie?
