Amp advise

[Npride]

Hello

I currently have a monolith 7 channel amp that powers my Front, center, rear and sides. I am thinking about adding another monolith amp to power my 4 height channels. The problem is I am running out of room, so i may need to sit my Marantz SR7011 on top of the 2nd amp. All the equpiment will be sitting on the top shelf. There is plenty air circulation so I am not worried about it getting hot. I may also add a blower to keep the amp cool. Can any tell me if I can stack these units without causing problems?

Assuming you have air circulation as you mentioned...you shouldn't have any problems.

A fan wouldn't hurt though. I have my 3 monoblocks stacked and they don't run hot at all.

Unless you have a large room sitting far away, like 4 meters from the height, another Monolith won't make a difference

Given he's light on space...Unless the OP just prefers to have the SR7011 function solely as a pre/pro, he could easily power the 4 heights with that.

My main concern would be the strength/stability of the cabinet holding all the weight.

The 2nd concern would be the heat from 2 big amps going up into the Marantz AVR, but it might not be an issue.

Agreed, and besides, it is a fact that unlike the left, right and center channels, the height channels will not have demanding contents all the time so the SR7011 should be able to deal with them with ease. One of those quiet AC Infinity fan you have been recommending will be an extra insurance. I actually think there is a good chance even set to Eco auto, will keep the SR7011 quite cool.

Why would you need a separate power amp just for height channels??

Because he is, I think, using the 7011 as a processor and while it has 9 amps built in you cannot unfortunately treat that as a generic pool. If he is using the Monolith for 7 main channels then to do 4 heights/overheads then he likely needs at least a stereo amp in addition to do the other pair. It is a pain that whilst it can, to a degree, assign some amps, the flexibly may not allow the precise use he is looking for.

5.1.4 or 7.1.2 would not be problem at all with what he now has.

A nice little stereo amp on top of the Marantz would likely not be too much of a problem regarding heat for either if it does not complicate the wiring too much.

You mean it would not output the Atmos channels through the Marantz amps if he is using an external amp on the other 7 channels?

The Marantz AVR produces a lot of heat and you definitely shouldn't put anything on top of it except fans if you want it to last many years.

@ Mtrycrafts
Like my 6012, it has 9 amps and 11 speaker terminals. You can set and power a 5.2.4, 7.2.2 or a 7.2 and Zone 2 Stereo. I think even a 5.2.2 and Zone 2 is possible. You can also bi-amp the left and right at the expense of 2 of the atmos terminals. If you use the pre-outs for the 7 base layer channels, then even though 9 are available in reality only 2 could be used for atmos. You could use the Monolith as a 5 main channel and use 2 for atmos and therefore get 7.2.4 without any additional external amps.

@Verrdinut, if it's only acting as a processor then the it is just drawing 70-80w so barely warm. 2 Channels driven it is noticeably warm but not unduly so.

I am using my Marantz sort of the wrong way round as a power amp, so I could in theory do a 7.2.6 combo if the Yammy supported it. It's doing the 4 heights for me and is also a small 2nd stereo system and stereo for the Projector. If the Yammy had problems then it could step in for that, but then I too would have those restrictions.

I already had the Yammy and the Nad for 7.2. The Marantz was on offer and gave me a cheaper solution to buying a 4 channel or 2x2 Stereo solution with the bonus of all the extra features. I fully realise it's OTT. The room is a mess, cables are everywhere and normal people run for the hills, but is working and I like it
