Rotel RB 1080 Question (1 Viewer)

[Dennis Oblow]

I am finally upgrading to 7.1, and I intend to add a Rotel 1080 amp to the 1095 I already have. How hot does a 1080 get, and how much air space does it need to cool properly. My system is in an audio cabinet so heat is a concern.

Dennis my 1075 runs pretty cool so I'd expect the 1080 not to get that hot either. You might want to ask the people on Club Rotel though.

The 1080 I had in my system ran very cool, even in an enclosed cabinet with 4" of clearance above it.

All of the Rotel amps I have ever owned except for the 991 ran cool.

You don't have to goto other websites to talk about Rotel.

Yeah, that 991 does run warm. Does anybody know why??

I believe it is because it is Class A.

My 1080 runs fairly warm but I've also got it in a cabinet with only about 2 inches clearance around it. However, I use it to power my mains. For surrounds, I bet it wouldn't get hot at all.

I'm really not sure why the 991 runs warm. I know both of mine do.

The 991 isn't class A, it's AB like all other Rotel Amps that I know of. In fact, it's virtually identical electrically to the 1080 (cosmetically as well...), so I'm not really sure what is responsible.
