i would also take a speaker over to the amp, connect it with a piece of "known good" speaker wire, and try it that way... just to ensure that it isn't a short in the existing wire...

not saying it IS a short, it could just as easily be an issue with the amp... but many "protection" issues have been traced in the past (not specific to emo, but in general) to speaker wire that the poster was SURE wasn't shorting... smile.gif

I had a similar problem with one of my Emo amps and it was due to a faulty RCA jack. It was shorting out intermittently and for a long time I thought it was the miniDSP between the pre-pro and amp. I stopped using that channel as I had an extra amp sitting around and the problem went away. If it continues to malfunction after trying a different wire to the speaker I would ship the amp back to Emo although I know how hard this is to do.

Yes, good idea. I hesitated to suggest a speaker swap to locate a potential short because he says he amp only goes into protection when driven hard(ish). A short would put it into protection regardless of the load wouldn't it?

 

But yeah, easy troubleshooting is always time well spent.

Yes, I'd forgotten about your faulty RCA jack. I hope the initial negative experience doesn't put the OP off Emo amps for good though. I can sympathise with him having worked the OT to get the cash together, looking forward to the fruits of his hard work, and then it's not working as it should! A real bummer.

post #15245 of 17194
Yes it is a bummer. After all his work he deserves a trouble free amp. I don't know what the current situation is with Emo's quality control but there are not a lot of posts about defective amps so I assume there isn't a wide spread problem.

Agreed. I think he may have a defective amp - can happen with any manufacturer that something slips through. The true test is what the manufacturer does after the fault has been reported. I am sure Emo will sort it all out for him but I can imagine his disappointment. I'd have felt exactly the same. It'd be a great shame if he turned his back on Emo amps because of this. As you say, there are very few reports of problems with Emo amps.

+1

Especially with first time amp users. Very easy to overlook.
No biggie, we have all had this happen to us at one time or another.

But as stated before, call them after you made 100% sure it isn't a short somewhere external to the amp.

Even if you have to ship it back ask them to give you their shipping discount.

They ship it back to you on their dime.
post #15248 of 17194
A defective driver / chassis / crossover in one of the speakers might cause the same problem.
post #15249 of 17194
Hello All,

I just wanted to chime in on Emotiva amps and issues. I have both a XPA2 and XPA3. My XPA3 started going into protection mode a couple weeks ago. I traced every wire to make sure there was no short. The issues persisted. I called Emotiva and talked to Fran. We tried to trouble shoot first - I did a 'bench' test with the unit out of my system. The problem still occurred when all three amps were driven simultaneously. So I sent my XPA3 back to them. They ended up replacing the CPU which controls protections modes. I got it back yesterday and hooked it all up and it is again Rock Solid. The turn-around time for all of this: I shipped it out on Dec 7 and received it on Dec 21st. That is pretty good (the fastest turn around time I've gotten from any vendor). So, if your unit is going into protection mode (and you exhausted all other possible faults as mentioned by others - especially shorted speaker wires or faulty interconnects), then the issue can be the same as mine.

Same problem here. Some time ago I bought an used one year UPA-5. After some time, the RCA jack of the FR channel got loosen and started to shut down (into protection mode) I just paid $35.00 to be soldering again, problem solved.

Right now, the RCA jack of the Center channel is also loosen, but is ok, no problem with any shut down (yet).

A friend of mine also bought a brand new Anthem MRX 300 Receiver and it had the same fault. It sent it back, it was repaired and once again, had the same fault. He was told the board (back) was a generic one, made in China and it seems it a was common control quality problem.

So, if that is true, , all the companies doing business with Chinese partners must be very cautious and take more quality control measurures (supervising) of their final production units.

I have no clue as to the scope of Outlaw's programming team, but they did want this to come out quickly to market.

All speculation at this point.
The question for me is: is Tone Winner's programming team any better now than they were the first time? Initial reports seem positive, but it's still early days. No one has even discussed what the PEQ capabiities are. Q range, frequency resolution and range, etc.

... Does the subwoofer EQ really equalize the subwoofer channel or just the LFE channel like last time? ... Are the channel EQs and delays applied after subwoofer mixdown or before mixdown like last time? ...

I purchased my XPA-5 used, early part of 2012 and it has a transferable warranty good for a least another 2 years. I was aware of the questionable integrity of the RCA connections before purchase, but in my own folly put too much lateral pressure on #1 during an equipment move, and it started to break. It was is still functional with no noise issues as it hung there with the cable attached. It stayed that way for a few days until I received 5 new XLR to RCA cables from Monoprice, which have worked out extremely well.
I decided this was better than going through the hassle of shipping it to Emotiva for repair, along with all the packing/unpacking and time involved. Just fortunate for me the XLR input is an available option and in the case of these amps might well be the preferred connection. No excuse for my own mishandling but does not totally justify the absence of a more robust RCA connection.
As far a preformance, I am more than pleased of the capability and the value the XPA-5.

Like you suggest to others, get one and tell us. tongue.gif

jk.
Who knows until we see a REW output of the changes. confused.gif

Hey everyone just off the back I am completely new to the processor and amp thing, all I have is a pioneer vsx1121k and was on the fence of replacing it to push my 4ohm speakers well im 90% going to do it. What i planned to get was an umc-200 and a xpa-5 do you guys think this is an upgrade considering most in this thread would run laps around me audio wise. Also when and if i do get this set up what other things do i need to connect my 5 speakers is it just take wires from back of vsx and connect it to umc-200 or how does it work, how do i connect the umc-200 to the xpa-5 etc..,like i said im a baby when it comes to this so forgive me, can somebody please school me on what needs to be done thanks a lot in advance.
post #15257 of 17194
can someone please comment on my previous post. Another option is using the vsx-1121 pre outs and getting a xpa-5 hooked up to vsx-1121 pre outs, is there a difference in doing this than getting an umc-200 looking foward to you guys input thaks

so how is your pioneer doing at driving your 4hm speakers? the 1121-k is rated at 110w per chanel at 8ohm, so it should be able to drive them just fine. what are your 4ohm speakers? I bought the xpa3 because my previous amp was to small to drive my new Wharfadle's. With all that said, the xpa 5 should do well at any 4ohm speaker package you have. I find my emotiva amp to be of great build quality. and can deliver great sound to my wharfadles.

have you out grown your current pre amp ability's? do you want zone 2 or zone 3 ability's? or any of the other ability's that the umc would offer? if so, go for a new pre amp and amp combo. if the umc-200 gives you nothing more than what you currently have... buy the xpa5 and use your pre amp outs from your pioneer. I'm currently looking at a pre pro as well, having zone 2 and 3 is on my list.

Why do you want to buy a UMC-200? Does it have any features your Pioneer doesn't have?
Why do you want to buy a XPA? Isn't your Pioneer capable of driving your speakers?
post #15261 of 17194
First off i want to say thanks for the response. like i said ima newbie when it comes to this stuff, but i was looking at the umc-200 thinking it would be a better upgrade with the xpa-5 to power my 5.1 surround sound is main reason. The more i think using the pre outs and getting a five channel amp would pretty much be the same i just thougt i would be loosing SQ that way. Also everytime I turn it up loud at about -15db my right surround speaker goes out well the tweeter gets fried you can still hear out of it just no the highs and sound low and im thinking this is from receiver not pushing enough power. Any more suggestion is welcomed love this forum and you guys expertise helps alot, and how do I hook up the pre outs to the xpa-5 what chords i need do speakeer wire stay connected to vsx or do i reconnect to xpa if i go that routee. Again I just thought it would be a better set up to give me better sound but from sound of it using my pre out and the vsx as a processor with amp would be the same.

Ok I'm stabbing in the dark but here is what I'm thinking. I had the same thing happening with my amp before i bought my xpa3, cracking sounds from my speakers. My Wharfdales have separate speaker terminals for the woofer and the tweeter. I have separate wires running from the xpa3 to the speakers. this gives a more stable amount of current to the speakers. on top of that you should use a heavy gauge speaker wire. If you are currently using a heavy gauge speaker wire, than yes a new amp may solve this problem. this assumes that your speakers are not the problem. and the amp is.
To hook up a power amp, use RCA cables from you avr pre amp out, to the XPA5's inputs. speaker wires will come out of the XPA5.
post #15263 of 17194
Thanks alot im pretty sure it is my amp this has happen to two other speakers on the same line so ill just get five rca wires and switch the speaker wires and i should be good to go thanks again for all the informative information. Ill keep lurking these forums to see how the 200 turned out for folks

Why do you want to buy a XMC-1? Does it have any features your Onkyo doesn't have?
