Sure seems like you have a problem elsewhere. In your speakers or wires or interconnects or the pre or something. You appear to be frying your amps.
Bring it to the dealer and play it on his gear and see if the same thing happens. I bet it doesn't.

I'd have to disagree with that because my old onkyo receiver was fine.
In order to be thorough, i did go through all of my speakers and wire checking for issues but didn't find anything. I wish it was that simple, it sure would have saved me a lot of hassle!

Something is amoss |

Are you certain that the "static" isn't being generated by the MC-700 as it heats up...? There's an entire thread dedicated to the MC-700 and issues resulting from the lack of top venting. Their solution was to apply a stick on heat sink to the DSP. If your old Onkyo receiver has pre-outs, maybe you could use it as a processor just to eliminate the MC-700 as the source of your issue.
Just a thought...

I can try that and see if i ger static when using the receiver preouts. My mc-700 is from the new batch, and has the dsp heatsink. Either way, I'll try that next.

I wish it was that simple, it sure would have saved me a lot of hassle! That doesn't necessarily disprove it, it just could be the Onkyo handled the short/issue better. It also could be the MC and/or your wiring to the MC is the problem since you didn't have the MC hooked to your Onkyo. The odds of 2 Emo amps having the exact same problem, while no one else has it, is low. If you hook it up at the dealer and it doesn't do it, you know it's something else of yours. If it does, then it's due to Emo and it is time to move on to a different amp. |

170f over the heatsinks tells me the ouput devices are much Hotter. The static is these devices just before breakdown. IMO long-term reliability has been compromised. Check Audiogon for a Parasound A51 This is 250x5 and some wacky 4 ohm rating as well. You might have to find a better location for this beast, however. It is a High Bias design so will run warm, but transitions (not 'switches') to a lower bias A/B regimen at maybe 12 watts per side. I see 80lb listed as 'net weight'. I don't know a 'fair price' or the seller or condition, but you might want to drop this guy a line. www.audiogon.com/listings/multi-ch-parasound-a-51-2017-09-18-amplifiersCan your DEALER duplicate your problem? Have they tried? Your speakers are fairly high sensitivity (NOT efficiency) so should not really stress out most amps. |

We do know he is the only one reporting it on this forum. True but it's been out a while and people normally can't come here fast enough to report the smallest of problems let alone this. Plus if it has been happening, Emo would have a standard answer or process to deal with anyone subsequent like Jim. It could very well be an Emo QC issue but I give that less odds, and he can easily confirm it by hooking it up at the dealer. |

I have my new 5175 set for a couple of days now and I usually run it around 35-40 on absolute scale which is around -40 on relative scale on my La Scala's and Forte's on an a/b switch and Heresy as a center on a 3.1 setup. Today i ran it for several hours probably 5-6 ,and went in to check on it before turning it off and it was barely warm to the touch . My Onkyo 703 AVR was warmer than the 5175 and I'm only using the Onkyo for its pre-outs . I am not familiar with there pre-amps yet . I also have not utilized the 12v trigger on the new 5175 as I did my UPA2 which also ran cool . My Onkyo has to have Zone 2 active to use my 12v trigger and it always made my Onkyo pretty warm over its circuitry . I plan to order a USB fan set for it, same as I have on my main theater which is AVR only to help it remain cool. Good luck with the AVR fixing you're issu. I too am really enjoying the sound quality of this amp and so far "knock on wood " have not had this issue .

My Sherbourn Pre/Pros run hotter than any of my amps. I know the Onkyo/Integras you can fry an egg on so that is where most of the heat should be coming from. The only amp I have owned that ran hot at all was my Gen 2 XPA-1. |

Not true: emotivalounge.proboards.com/post/906989/threadI had the same issue. Very hot after 1.5 hours then heavy static/distortion from the speakers. I didnt report it here until the OP posted the same issue. |

Waiting to hear if the DEALER can duplicate the issue.

Alucard, mine has the exact same symptoms. I have tried everything, and nothing I can do has fixed the issue. I am.going to just call the dealer tomorrow and see what they say. It's a serious inconvenience for me simce it's a 3 hour round trip to the dealer 😕

It's a serious inconvenience for me simce it's a 3 hour round trip to the dealer 😕 A lot of people have suggested that the issue is in my setup, but I have checked every wire and speaker very thoroughly. Also, the MC-700 is not getting warm... so the easy stuff is out. Alucard had the same issue, and I am on my second unit, same issue. The big problem here is that I don't want a third unit, so I'm going to have to step down to an A-500 or pony up the money for 3 A-300 amps, or an XPA-5. This isn't going well. I'm going to call Emotiva tomorrow, and hope that they have opened and tested the unit that I shipped back and can give me some insight! |

Wow, I hope the Emotiva QC process has not taken a hit. Something to be said about growing too fast.

Were you able to duplicate the problem with using you're receiver pre-outs ? Never seen an update wether that was a pass or fail. Also I can't remember if you stated if the heat was there from day one or if it all of a sudden started to present itself. I have played mine daily for 2-3 hours straight since I have gotten it and it played most of this past Sunday and was still not as warm as my Onkyo that I'm using for its pre-outs . Just curious if both that are having this issue are using Emotiva pre-amps . The only other issue I've heard about with this unit is another user had his trip and reset itself but that was likely from heavy clipping of a center channel speaker . Reconfigure there settings and have not heard of them having a repeat issue or the heat problems being discussed here.

My A-500 is having static issues also. It doesnt seem to have static when initially turned on but the static will appear after a period of use. Have had the static with nothing connected to the inputs just my speakers. Although my A-500 doesnt seem to be getting hot like the others.

Quamman, sorry I forgot to mention that in my last post. I tried my receiver preouts and had the same results. I'm going to call Emotiva after lunch and see what they found with the unit that was shipped back.

Have had the static with nothing connected to the inputs just my speakers. Although my A-500 doesnt seem to be getting hot like the others. That's how my A-5175 is. It sounds great and noise floor is very low... then, when its been on an hour and a half or so, it will start producing a fairly loud static sound through all of the speaker channels. If I shut the unit off and wait until it cools down, it will play quiet until it warms up again. |
