The standard XLR orientation for “European“ amps is 1 Ground, 2 Hot, 3 Cold, whereas the standard XLR orientation for “American” amps is 1 Ground, 2 Cold, 3 Hot. Not all amps made in/for Europe use the European standard orientation and not all amps made in/for American use the American standard. The Emotiva amps I have encountered all use the American standard. The preamp outputs should match the power amp inputs. There are XLR cables available that swap the 2 and 3 pins so that, for example, a European pre amp can be used with an American power amp. In regards to power amp input Voltage, the maximum voltage between the ground and the hot pins is commonly around +2.2 volts. Between the ground and the cold pins is around -2.2 volts. With that in mind some power amp manufactures quote the maximum input voltage as 2.2 volts and some quote it as 4.4 volts. Personally I’ve never really concerned myself with power amp maximum input voltages, they play so loud at 0.5 volts, whether the max is 2.0 volts or 2.4 volts is irrelevant. Cheers Gary Except that the days of "European" and "American" standards are long gone. There's only one standard and that is EIA Standard RS-297-A (which was adopted in 1973). This standard defines the XLR3 pinout as pin 2 "hot" and pin 3 "cold". This standard was also adopted by AES and has been the " standard" XLR3 pinout for line level audio since the 1980's. Outside of Emotiva and Sunfire, I've never encountered a "consumer" grade amplifier that did not follow the adopted XLR3 standard... Be nice if Emotiva packaged the adapters or sold them on their site. At the very least I think there should be a note somewhere on the product's specification. Just think of all those phase issues out there without a lot of people knowing whether their speakers are coming or going pushing or pulling in sync. Spread awareness! J/king

Just keep all of your analog signals flowing through Emotiva equipment. No, wait. What phase does my Sherbourn equipment have?

This turned into a XLR polarity thread, but I'm still wanting to discuss voltage requirements for DR amp, or DR vs XPA and why. Thank you lol. Anyone who has posted lately, do you have any knowledge regarding the voltage requirements for DR amplifiers, and if so why it higher than XPA amps?

my Dr1s are connected to AVR Onkyo rz1100 by rca, and I have no problems ... div align="left"][/div] My Onkyo is the PR-RZ5100 if you meant to ask me. I had to double ck after reading the previous responses but this is the spec of the flagship Onkyo Pre-Pro: Rated RCA Output Level and Impedance 200 mV/1.2 k-ohms (Zone Out) 2 V/1.2 k-ohms (Zone Pre Out) 1.0 V/330 Ohms (Pre Out/Subwoofer Pre Out) Rated XLR Output Level and Impedance 2.0 V/220 Ohms (Pre Out) www.onkyousa.com/product/pr-rz5100/Thank you, actually I thought you had posted in here, but then never saw the comment. I was actually asking Mac about his Onkyo 1100 and hoping it was an AVR and not a prepro lol. I know most prepros have more voltage.

I did not have xpa g3, ..... before I had XPA 1 gen1 ,gen 2 and XPR 1

IMHO DR1 are the best of them all, .... better resolution and musicality,...without any loss of performance I did not have xpa g3, ..... before I had XPA 1 gen1 ,gen 2 and XPR 1 Excellent. Did you notice any loss in performance or level switching to the DR1?

On Emotiva's product page the DR3 input sensitivity is listed as 2.0v. Don't know whether that's a recent addition and answers your question?

I wasnt aware before I purchased. Well, we know that things on paper can't be trusted but online information can be. J/king on this Sarcasm Monday. When convenient I'll call Emotiva and ask which is the correct information, that is, if you don't beat me to the punch. You said the 2.4v is stated in the manual? And that's not some individual amp spec sheet as tested? Enjoy, William

I hate to get embroiled in this, but I DO have a question and comment.
Is the 2.4volt sensitivity single ended or XLR? If XLR, is that 1.2v PER LEG or 2.4v PER LEG?
Every proper XLR device I've ever encounterd has been louder' thru the XLR than single ended because while the same output voltage, it is actually 3db (or is that 6db?) higher in output.
