Klipsch 7.2 Dolby Atmos

[Shari Alvine]

Theperson helped me setting up the home theater system couldn't able to connect rear floor standing height dolby atmos speakers to the receiver. He said the RP-8060FA speakers has additional inputs for height speakers that cannot be connected to 9.2 channel receiver.

The good news is that you most certainly can connect your Dolby Atmos speakers to this receiver, as your receiver does support Dolby Atmos. I'm not familiar with the specific connection arrangement of the Denon receivers, as I use Yamaha receivers, however a quick look at the user manual will show you how to connect those up-firing Atmos speakers.

The bad news is that it looks like you might have to forego using one pair of speakers, either the Rear surrounds if you go with a 5.2.4 setup, where the 5 represents: front Left, Front Right, Center, Surround Left and Surround Right, the 2 represents your two subwoofers, and the 4 represents the four atmos speakers.

Once you've decided which configuration your prefer, look this configuration up in the manual and it will show you exactly where to connect the atmos speakers/terminals and how to adjust the settings on the receiver to assign these height channels correctly. On the speaker side, the atmos channels will go to those additional inputs that you referred to in your post.

PS: I should mention that I don't own these Atmos enabled speakers as my atmos are in-ceiling speakers, and neither do I own this receiver, so if I have provided incorrect advice, I am sure one of the forum veterans will correct me... in that case, I apologize.

Thanks for pointing that out @wuzzzer. I (incorrectly) assumed he was meaning he wanted to connect/bridge the main terminals to the Atmos terminals, but I see now how the connections are set up on these speakers on Klipsch's website.

Hi JefDC, Thanks for your reply. Right now my rear height atmos speakers are not working, I think because of not having enough channels in the receiver. Do I need to connect external amplifier to make use of these rear height speakers along with other speakers. Do you know what to look for when buying external amplifier e.g. compatible with Denon receiver and number of ext amp channels etc.

I think if you have 3 front speakers (L,C,R) and 4 speakers in the rear (2 rears, 2 rear surrounds) thats a total of 7 speakers so far and the denon can only do 9 + 2 subs, so it makes sense why the rear atmos doesnt work. Hopefully the front atmos you can hear audio from. I have the same A/V and a similar setup with 11.2 channels using the denon and an Emotiva 3 channel amp to power the 3 front speakers. The second video I linked will show you how to hook up an amp to your receiver.

This will free up some power and allow you to run the 2 rear atmos speakers from your receiver once you add an amp to it. I'm still new to using amps as well but I've noticed the biggest difference in price is usually how much power goes to each channel and what class of amp is, the best being class A. Class A has the least distorted audio and cleanest sound from the receiver to your speakers. This is one of the better amps to get but it was too expensive for me to try out as my first amp:

So when you look at that amp you linked in the specs it says 80 watts per channel when ALL channels are hooked up to a speaker. Thats 80 x 7 for a total of 560w. If you only had 5 channels being used on the amp - that power would then be 560 / 5 = 112 watts per channel.

Now let's look at the 11.2 channel denon. The specs say it does 140 watts per channel when ONLY 2 channels are driven. Thats a total of 280 watts (half the power of the amp). So if you have 11 speakers hooked up to it that means you will have about 25 watts going to each speaker, and that is based off the denon spec sheet which usually optimistic at best. Not nearly as much power as an entry level amp.

So if you had the 7 channel amp driving all 7 speakers, thats 80 w per speaker output, with 4 speakers powered by the receiver now to get you to a total of 11 speakers. Those 4 would be getting 70w each from the receiver. Almost 3 times the power now then without an amp. Also the other 7 will be getting a cleaner signal from the amp and should sound better in addition to being capable of louder output.

Thanks a lot for taking time to explain these terms. I like the way you explained with examples. Much appreciated. I have much better understanding now with usage of watts per channel and advantages of having ext amps.

Also I asked about Emotiva ( -theater/products/a-700), is A-700 model a good ext amp to use along with my Klipsch speakers and Denon receiver? Sorry to ask you again, I never use ext. amp before and not sure if this will best suit for my setup.

No Problem - I think good is a relative term, relative to how much money you are willing to spend haha. What I would do is hook everything up with out the amp - as many speakers as you can. Watch a few specific scenes from your fav movie for a week. Then get that A-700 amp that or the outlaw-5000 is a comparable alternative and similar price, I think its only 5-channel though.) Then watch your movies again at the same volume level etc and see if you can tell a difference. Also crank it and see if it gets louder than you thought, etc. If you can't tell a difference return it, but I'm fairly sure you will be able to hear one. I would think of it as an entry level amp to start off with. If you get more serious you can upgrade it later and add an additional amp to your setup. The main Left Right Center channels in the front are the most power hungry speakers so they should get the amp power first. So if you got another more robust amp later, you hook it up to power your mains and maybe your rears and then have your old amp power your 4 height channels. It's all about having fun and experimenting - an expensive hobby but super fun I think lol.
