I ordered a new DR3 amp yesterday and just NOW read in the user guide that the input voltage for rated power is 2.4 volts. That seems pretty high for home gear. Does anyone else know whether this is true or not?

Does anyone else know whether this is true or not? Looking forward to a followup response. Just checked my Onkyo's maximum output voltage through XLR which is 2.0 volts.

IMHO everything is in perfect order, everything is normal ... for example, Mcintosch mc601/611, mc1.25 has 4.8 Volts Balanced 2.4 Volts Unbalanced ,... mc1,2 has 5.0 Volts Balanced 2.5 Volts Unbalanced Looking forward to a followup response. Just checked my Onkyo's maximum output voltage through XLR which is 2.0 volts. I'd really love to find out if this is true.

I had thought that the nominal "standard" for Unbalanced RCAs was 2.0V for maximum signal, and 4.0V for Balanced XLR. Either way, it's a little odd that the DR3 specifications state "Input Sensitivity (for rated power; 8 Ohm load): 2.0 V" without any reference to Unbalanced RCA versus Balanced XLR. Something seems missing there.

you're right ; ... the question is whether 2.4 volt applies to rca or xlr inputs? If the rca then the voltage sensitivity on xlr should probably be twice as high, ... and if 2.4 volt is on xlr then on rca it will probably be 1.2 volt, .... unless I'm wrong? For comparison, I found the parameters of my h30 and it is so; Input sensitivity for 1W into 8 ohms, unbalanced and balanced inputs Stereo and mono modes: 71.1mV ..... www.soundstagenetwork.com/index.php?option=com_content&view=article&id=1331:measurements-hegel-music-systems-h30-stereo-mono-amplifier&catid=97:amplifier-measurements&Itemid=154...In practice, both Emotiva DR1 and Hegel play great with the Mcintosh c52, Hegel p30 preamplifiers, ... Onkyo1100 ... personally, I always trust my ears, not technical data on paper I had thought that the nominal "standard" for Unbalanced RCAs was 2.0V for maximum signal, and 4.0V for Balanced XLR. Either way, it's a little odd that the DR3 specifications state "Input Sensitivity (for rated power; 8 Ohm load): 2.0 V" without any reference to Unbalanced RCA versus Balanced XLR.

He also said RMS and 1.4 was max which also doesn't make any sense.

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/

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.

Yes, I own a DR3 amp with an Onkyo PR-RZ5100. Are you using the XLR connections? Yes indeed. Just bringing up another point. The XLR inputs of the Emotiva amps allegedly have the pins reversed. Therefore, using an Emotiva amp with amplified or active subwoofers may lead to out of phase cancellations. Would like someone to actually touch upon both these points: What is the input voltage of XLR in the DR series amps? And do the DR series amps have XLR pins reversed which lead to phase cancellation when using "other" amps simultaneously with Emotiva amplification?

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

Anyone needing an adapter to switch the pins: www.parts-express.com/neutrik-na3fmx-3-pin-xlr-female-to-male-polarity-reversing-adapter--092-2410I just ordered 3 for the LCR channels my DR3 is using. This has been a major issue while trying to set up the system. I have been trying to use the 180 phase dial on the active subwoofers in order to invert the final phase from the Onkyo to my subs because the Emotiva amp doesn't match. The final output from the LCR powered by the Emotiva and the active subwoofer are not correct. The adapter, I think, is a better solution. As you can see the Onkyo use a different pin 2 hot or cold arrangement than the Emotiva amp. On either side of the XLR is a wiring a diagram showing the pin configurations:

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...
