X3700h, BasX A5 and 5.2.2 setup anything I need to know or worry about?

[Tenno6]

Currently I have the hardware listed in the title but it isn’t hooked up yet. With the input sensitivity of 1.2 on the amp am I going to have much of a problem with this combination of hardware and should I run all 5 main channels off the amp?
A lot of this is confusing with the voltages and stuff.
my surround speakers are 600m and my center is a 600c. My fronts are R-820Fs and my in ceilings I couldn’t tell you what they are lol.

Thanks

What are you worried about ? To much or to low of power ?

Amir on audio science review did a review of the x3700h it measured well and the preout sensitivity for all amps is good up to 1.4 so you the x3700h should have no problem driving that basx amp since it's max is 1.2 you have nothing to worry about

The pre-outs of the Denon should work great with an amp of that sensitivity. Your power amp spec is close to the avr's amp spec, take your pick as to which channels to hook up.

Thanks for all the replies. I’m just dipping my foot into audio so I will misunderstand and mix things up a lot as I learn about it all. For some reason I thought I read that you didn’t want to be above or below input sensitivity.
The 3700 should be able to run the pre outs and also internal amps yes?
What is best practice for external amps vs internal? By that I mean is it better to have the denon amp the in ceiling speakers and external everything else? I suspect only amping two channels with the denon should help balance everything out though in terms of how much power everything gets so it probably doesn’t matter too much how I set it all up.

Yes the 3700 can do both external amps as well as internal amps simultaneously; generally avrs that have pre-outs, they're live all the time. Most might put more powerful amps on the front three or maybe five or even seven channels, or all of them; keep in mind a doubling of power is only 3dB more spl, too but at least doubling/tripling power via the external amp is more what I've done when using external amps and generally just the front three myself (in 7 and 9ch setups). The 3700 tested as well as several dedicated pre-pros over at audiosciencereview https://www.audiosciencereview.com/forum/index.php?threads/denon-avr-x3700h-avr-review.15031/

The pre-out level just needs to meet the amp's sensitivity rating in order to take full advantage of the amp's output capability, and the Denon is more than capable of 1.2V in any case. Try this article perhaps https://www.audioholics.com/audio-amplifier/amplifier-voltage-gain

In your case the external amp is close to the rating of the Denon; maybe just to take some of the load off the Denon I might use it on the mains that get most of the work. The more sensitive your speakers are the lesser your amp needs are, too, maybe just taking some of the demand away from the single power supply of the Denon. I've got an avr I use external amps with just because they're lying around (and are 3x the rated power of that avr) but I really don't need them at my listening levels, nor do I use any on several other avrs I've got setup.

You might also play around with this as what speakers you have at what distance and of what sensitivity all come into play http://myhometheater.homestead.com/splcalculator.html

You don't want the recievers preouts to be below the amps sensitivity it's not an issue being above I prefer a little headroom actually. As lovin said you can use the basx amp for whatever channels you'd like and use the av recievers amps for the remaining channels at the same time no problem with that reciever

That's a nice reciever it reviewed and tested quiet well actually I think you'll be very happy with it

Im happy with my 2700h so yeah I can’t imagine being less happy with the 3700 haha. I decided to grab it to take advantage of the basx I had already sitting in a closet and because I might add more in ceiling to get a x.x.4 atmos setup so the extra channels will help.

Are you concerned about the X3700H's pre out vs the Emo amp's 1.2 V sensitivity specs because of Amir's comments about the 1.4 V? If so, understand that Amir's comment regarding the 1.4 V pre out has to do with the very low level of distortions+noise he aimed for, not because it is limited to 1.4 V. Also, that is not even a factor if you use the preamp mode. In preamp mode, 1.4 V, 2 V or even 3 V doesn't even matter because distortions will not increase much if at all.

The X3700H pre out can exceed 2 V or even much higher at distortion levels much lower than that of your power amp so in terms of audible distortion you have nothing to worry about.
