The 667 does. Pretty good price too, hence why I mentioned it above.

Glad to see the reviews on this amp are pretty good. I am thinking of picking one up for my PC setup and feeding it from the ASUS Xonar Essence ST with the Xonar H6 multi-channel analog output addon card I have for it. Then Im thinking just some Def Tech ProMonitor 800's, a ProCenter 1000 and some small subwoofer to complete the system. Should be a decent enough upgrade from the Logitech Z-5500 that has served the task well for many years now.

I am adding a Sound Blaster ZxR sound card to my system with 5.1 analog outputs (not interested in the digital outputs because they are all lossy). Apparently, in the last few years 5.1 analog inputs have become very hard to find. I am thinking that I can feed the 5.1 analog outputs from the sound card to the Emotiva UPA-500 and then to a set of 5.1 surround speakers, with the sub-woofer having its own amplifier. Does that sound reasonable? This is for a single room, perhaps 400-500 sq ft, so the power output should be more than adequate.. I also considered the UPA-700, but I don't really need 7 channels and each channel has a lower power output.

 

I started by looking for something a bit better than the really low end 5.1 speakers that Logitech and Creative Labs offer, but everything I found was discontinued with the exception of Logitech's z906 which doesn't get very good reviews (LOUD, good for gaming, bad for music). I then looked at AVRs -- which are really a LOT of overkill for a sound system -- but, again, they are all very, very expensive or don't have 5.1 analog inputs (mostly both). Since all I really need is an amplifier to drive the speakers, the UPA-500 appear to be ideal. Mid-level in cost, good performance with no wasted features.

From the user manual it used a 350VA transformer, so it can't be 80W or 140W all channel driven. If 5 channels deliver 140W that require at least 700W power supply, even on a 100% efficient amp. Did I missing something?

Ever heard of storage capacitance? Also, the load on an amp is not constant, like that of a light bulb.

Anyone know where I can pick one of these up? Emotiva's website says it is no longer available. frown.gif

I'd rather not have to get a UPA-700 as I have no use for 7.1 on top of spending $100 more

They are probably temporarily out of stock. Call them and ask.

Sure doesnt sound right. Im sure they will take care of you though. Their warranty service is supposed to be great.

Couldn't resist, with atmos coming up, and me wanting a new processor, I need some more amplification. While my adcom 7807 does just fine for my 7 channels, I would like to upgrade to 9.1 plus some ceiling channels for atmos if I deem fit. The price on this amp currently is the best you are ever going to find, and twisted my arm until I finally bought one. Thanks emotiva.

don't forget to call and ask for B-stock if you want to save some cash...That is how I ended up getting mine UPA700 for $275.

Ok this is a total noob question but just bought a UPA-500 to amp my Pioneer SC-1222-K - how do I connect these two?

I know to use the Pre-Outs but I'm unclear on what cables to use.

Thanks in advance.

Plain old RCA cables, available just about anywhere, I buy mine from monoprice or RadioShack.

Ok received my UPA-500 and rack mounts and installed last night. However, got a loud HUMMMMMMMM until I unplugged the Internet switch. Can't really leave this unplugged so wondering what my options are.

Would a power conditioner make a difference? Or a power strip for the rack?

Search for hum and ground loop. There are many potential solutions but you are probably going to want a ground isolator for the amp or switch.

UPA-500 alternative?

I am building my first HT and a buddy recommended the UPA-500 for my set up. Emotiva is out and not sure when the replacements will be produced in 2015. Does anyone have recommendations for a comparable product?

Nobody makes a five channel amp with only 80 watts per channel. That may be why Emotiva is retiring their UPA line(once again) since there isn't much market for it.

Why not the Emotiva UPA-700?

they are out of that product as well.

Looking at the Emotiva XPA-5- but the UPAs seemed like a good price point, but as Audio4Life points out there may be a good reason

80 W/ch is just not enough of a step from most AVRs. People may buy them so they can say they have an external amp, but those actually needing an amp likely want more power than that. Probably more than an an XPA-3/5 as well, but that's another topic. Those investing in seperates are most likely looking at XPA/XPR amps. All of which is a long way of saying I agree with audio4life.

For suggestions for other manufacturers' products, post in the new thread (or search for one of the many comparison threads).

Personally, I'd ignore the buddy and put the money into a better AVR or speakers rather than into an external amp for your first HT system.
