I'm not worried about average volume but having enough headroom for the big peaks.

What do you think?

Outlaw 5000 has twice the power per channel but no balanced inputs.


what/how many speakers are you planning on running? are you looking at the XPA-11?

I was going to use for all of the surrounds as a minimum. I have some pretty good amplification for the LCR.

I think the potential conflict depends on the wiring in the AVR/AVP. When I was researching for my new AVP I noted that the Marantz products (AVRs and AVPs) have the European configuration. I don't know about Yamaha, Pioneer, Onkyo, Arcam, etc. I ended up buying an Anthem AVM 60 which seems to have the American (Canadian?) wiring as I have had no trouble with the XPA-7 Gen 3 driving the main channels on the Anthem.

This discussion has raised another issue for me. When I had a Yamaha AVR and an Onkyo AVR before that, YPAO and Audyssey would identify channels that were out of phase. For the Anthem Room Correction I don't see anything to indicate that it will identify an out of phase channel. Perhaps it does and internally corrects the phase. Something to check when I next run ARC.

BTW - I am using Blue Jeans XLR balanced connections from the Emotiva to the Anthem. They are "regular" XLRs as far as I know.

The out-of-phase condition is not something you would even notice if you use only the Emotiva amp because "all" your speakers would be out-of-phase and thus relatively in phase. It has nothing to do with being able to power the speakers. And even if someone was using a second amp that had the same XLR pin arrangement as their pre-amp, but different than the Emotiva, it still might not be very obvious that the speakers driven by the two amps are relatively out-of-phase.

Most people (myself included) were tipped off by Audyssey, which would show all speakers driven by the Gen3 amp as out-of-phase.

Not to sound like a broken record, but it is very important to check the phase between your speakers, especially the fronts, and your subwoofer(s). Since most subs are wired in the AES standard (American) way they will be out of phase with speakers run through the XLR's of the XPA Gen3 amps. If they are out of phase the music/soundtrack at the crossover you set will be affected.
Here is one (of many) ways to check speaker/sub phase: https://www.soundandvision.com/conte...phase-easy-way
It's worth your time and effort to check this out.

Note room correction programs should automatically fix the phase for you. And since speakers are in general at different distances from the MLP in general phase may vary anyway. It is important all speakers be in phase at the MLP, and for subs it is important that they be in phase with the other speakers at the crossover frequency.

This is my point, and the article shows an easy way to check this. All you need is a good SPL meter (I use my trusty old RS), a disc or download that has test tones at different frequencies (specifically your x-over freq) and the patience to do the measurements.
Doing this test I found my SVS sub to get the best reading when its phase is set to 180*. I actually fixed this by attaching an XLR 'phase reverser' -
https://www.amazon.com/HOSA-XLR-COUP.../dp/B000068O4L
and set my sub's phase at 0* which also produced the best results.
Most RC programs do not check sub/speaker phase. I think maybe the advanced Audyssey does, but I would check the sub/speaker phase at the x-over no matter what RC I am using. But that's just me. YMMV.

Yes, I follow all of that. I have my four ceiling/ATMOS speakers driven by an Anthem PVA-4 using unbalanced connections. They could be out of sync relative to the seven main channels. If they are I haven't noticed any problems with the sound or when I ran the ARC room correction.

The unbalanced inputs on the Emotiva do not have the phase shift issue, just the XLR inputs. So it is a flip of the coin as to what inputs you should use to match the phase from the Anthem amp. It might be a good idea to perform phase test with an SPL meter per the link provided by tngiloy.

My 5 channel unit has the same very low-level hiss, volume independent, and I've learned to just ignore it and will never purchase another Emotive unit. All the previous amps I've had over years including my most recent Parasound units never had this hiss problem, they all were stone quiet.
Hmm...my XPA-7 I just bought is dead quiet.

Emotiva Gen 3- less heat?

Hi all,

The wife is planning a cabinet with limited air flow. Of course I'll do what I can, but do you guys know if the new emotiva amps run cool at idle or light "throttle"? Or, any other amps/technology that runs fairly cool compared to "traditional amps"?

thanks!

They run cool. Make sure the cabinet is deep enough to house the amp and connectors.

I have an XPA3 Gen3. It runs cool - cooler than the Denon AVR-X4300H that feeds it. I admit that I rarely run the system at head-banger level.

However, both are in an open rack. "limited air flow" sounds a little worrisome to me. I hope that the cabinet is conducive to adding a silent fan, if things get a little hot.

As codyjenkins posted, it's deep. It is spec'd at 19" (more needed for the cable connectors). By comparison, the 4300 is spec'd at 15.3" deep.

You must definately check this out. There are many solutions and can email them. I have a rack that has access to both front and back with doors, but had no provision for air. I then contacted acinfinity and suggested to modify my back door. I installed two fans on the bottom of the door, that suck air in and two on top (since hot air is lighter than cold) for exhaustion.

In my case, where I have a VERY hot PS4 Pro, it helped a lot especially now on summer.

Thanks! I currently run a t9 on top of my denon 4400 and their dual plate where I have my gear currently.

We’re going to be converting the wood storage of our fireplace into a media cabinet so I’m not sure what I can do to the rear. We’ll have to see once we get it deconstructed a bit.

You can put a pair of exhaustion fans on the right side at the top. It works this way too.

Any experiences with the XPA-DR series? They seem to be the new top model fra Emotiva though I have not found many opinions or reviews. Would love to see the typical Stereophile measurements.

I'm also interested in the Emotiva Dr1. I'm looking for a good 500 watt or more two channel setup. I've owned the first generation Wyred4sound SX1000 monoblocks. I have not heard any of the class D audio amps from D Sonic or any hypex model. I want cost-effective monoblocks so it appears the emotiva Dr 1 would be the best value right now. I am desperately looking for opinions on them at this time. Any owners in this thread care to give their impressions of Emotiva Dr1 or Dr2?

Just hooked up an XPA-11 Gen 3 with 3 Single cards and 4 doubles, confirmed with Audyssey on a Marantz AV7702 pre-pro that all my speaker channels are now out of phase, interesting since it says European and so does Marantz and so does the Lexicon LX-7 replacing it, so Emotiva's "Absolute Phase" is different. I'm just going to swap the + and - plugs at the back of the Amplifier. Looking to upgrade to an RMC-1, so we'll see how phase works out at that point.

Emotiva's XLR's are out of phase. I thought the RCAs were in-phase but do not know for sure.

Just received my Emotiva XPA-7 Gen 3, received it 3 days ago, ordered from my local Emotiva dealer. Have to use a temporary shelf since they forgot to send me the rack ears I ordered.
