Emotiva XPA-3

jimmydep

I too enjoy my XPA-5, In my system it sounds better than my Sunfire. I haven't had any issues with the amp going into protect mode, at any volume, and it runs cool.
Lately I've been considering going the "Tube" route, but still have a little more learning to do, and am concerned that I may have trouble driving the LSi-15's

HMMM, I never had that problem and I have swapped out many IC's.
I have never seen a amp protest but with some of the threads here I would not be surprised.:eek:

maybe I got a bad one? not sure but I haven't been able to completely fix the issue yet. sometimes the amp just shuts down when changing sources in the avr. not a deal breaker but it is annoying

Never have owned an Emo but I do have a question. How can you accept that an amp shuts down for no apparent reason? This seems to be a recurring defect and fail to see how anybody could accept this as a normal operating parameter.

I enjoy my xpa-3, I think it was a huge step up from just the avr. One thing about the emo, and I've heard the same complaint from other xpa owners, is it is real finicy as to which ics are used. Some ics will throw the amp into protect mode at higher volumes. Also changing sources does the same thing. I've switched to mits and the volume issue seems to be fixed, but still goes into protest mode sometimes when changing sources.

Never experienced the IC issues or protect mode when switching sources, but I have heard about the finicky IC issue. I recall ACSubie had that issue with Ben's silver cables (that IIRC was resolved). I believe the issue was attributed to the unshielded IC acting like an AM antenna or something and triggering the protection circuitry (and it can also occur with defective ICs)--I don't have the discussion link handy, but I posted it a couple times -

I've also had my XPA-5 into the RTi-12's driven quite loud and never had it go into protect mode.

Hmmmmmmm............I've never owned an amp that had protection circuitry. Always rail fuses but never protection circuitry. Another thing in the signal path that is unnecessary, IMO.

Your issue could be the Amp or the AVR. You need to call Emotiva Tech support to get your issue resolved.

I haven't heard anybody have any IC issues with the inexpensive Premium Monoprice ICs, so you might want to pick up a set and see if you still have any issues.
Also I'm not sure what would happen if the switch is wrong, but make sure the switches are set to unbalanced.

Is it just a specific channel that goes into protect? or all channels? If just one channel, try switching the ICs around and see if the issue follows the IC or remains on the same amp channel.

You're right. What morons for putting protection circuitry in. What the hell were they thinking?
We are talking about a Home Theater application here right?

heiney9

I guess I don't understand..............from a design POV why would Emo make the protection circuit so sensitive? Any robust, well built amp should have a protection circuit kick in only for a catastrophic event, like shorted speaker wires or perhaps a transient spike when one swaps I/C's while gear is powered up.

I'd really like to understand why *some* of these powerhouse amps are quick to go into protect? Perhaps just a manufacturing flaw, but while I haven't done any hard research it seems to be more than just a few isolated incidents.

I agree. They are set too sensitive and I hope they make design changes in the future for that.
It would be nice if that were a user adjustable setting.
The last time I spoke to Lonnie, teh Emotiva Engineer, he said they can adjust the sensitivity in the shop and make them less sensitive.

Not nearly as critical compared to a dedicated 2 channel music only rig.

Yeah, I see your point. There are some real idiots out there so perhaps it's Emo just being very over protective (pardon the pun).

You want a REAL performance car get yourself a Porsche, Ferrari, Lamborghini, Lotus, BMW, Mercedes....

See how that work's?

You're an idiot. Explain exactly how the Corvette is NOT a real performance car. I don't even like Corvettes and i still think that was an utterly retarded statement.

You should be more than happy with the upgrade.

Hey Guys,

I am inheriting an XPA-3 amplifier from my dad who is upgrading to a UPA-7. My modest 7.1 system consists of an Onkyo SR-706, a pair of Polk M50's as the mains and a CS10 for the center.

I know the mains aren't the greatest but do you think the amplifier would help them out a little?

Thanks

Lotus, are you kidding?? Talk about a POS! How many of those cars have you driven? I've driven every single one, and owned several, and while my 500+ hp Vette does not have the luxury, it will show it's tail lights to many models from all those marques.

Thank you for assuming, YET AGAIN! I actually have driven those car's. Prior to my accident, and subsequent disability, i was an automotive service tech for 15yrs and as such i had the pleasure of driving MANY nice car's, both foreign & domestic. I have also BUILT a few along the way but let's not turn this into another pissing match

I was simply using the Corvette as a comparison because IMHO it would be the automotive equivalent of the Emotiva amp To me it is nothing more than a glorified Camaro. Sorry if i hurt your feeling's

I would call them up and have them send out a replacement, that is not normal.

Would it not depend on where that circuitry is located in the signal path?

You couldn't be any more farther from the truth and to be honest i have not learned anything usefull from any of you! Unfortunately (or fortunately perhap's? lol) the only thing i have learned here is how to be an arrogant, ignorant fool.

Again: Quit projecting your self hate. If you were 1/4 attentive as you think you are you would notice that i live in Canada so "your" education system has NOTHING to do with me For your information, whether you choose to beleive it or not, i have been tested numerous time's and my IQ is in the upper level of the population.

So now we have the car vs amp analogy,not sure how that fits.

I am a little lost reading this thread too but I think the analogy applies to this.

Not all cars are created equal - some can go faster than others regardless of they have 4 wheels but some people think it makes no difference (just the same as some people think amplifier makes no difference in sound.) :eek:

Anyway, I must say EMO threads are always a good read and brings me chuckles and put me out of misery from yesterday.

Yeah I know what your saying but it doesn't tell me how good (or bad) an amp sounds.I would actually have to listen to it before I could express a credible opinion about it.;)

Yeah it's definately entertaining.

before I changed ics from mc to mit, it was the left channal that would go out at high volumes. with the new ics, it doesn't go into protect at high volumes anymore, but all channals go into protect at the same time when changing sources in the avr - not always but enough...I'll call emo but I bought this amp from a member here and its probably not covered under warrenty

Superjunior, I've never had this problem with two XPA-5's, a XPA-3, or a LPA-1 amp.
The receivers used include a Pioneer SC-07, VSX-1018AH, and VSX-1014TX.
I'm wondering whether it is a receiver problem.
Have you called Emotiva customer service and asked about it?

not yet but yes, it could be a receiver problem - can't rule that out

The 5 year warranty is fully transferable. You need to contact the company to find out for sure, how to go about it.

I got an early XPA 5, and I had the shutdown issue. I switched IC's, and smooth sailing ever since.
