Rotel power amp operating temperature

[TimbaLand]

Hi guys

I have a Rotel RB1090, RMB1095 and RMB1565. It is normal for the 1090 and 1095 to be warm to hot while operating because of them being Class AB. All my amps are in a closed cabinet with improvised ventilation. The 1565 is cool throughout operation due to it being a class D. The 1095 and 1090 feels a bit warm which I find interesting as they are fanless and they are in an enclosed cabinet.

Though this being the case I still would like to know what is the recommended operating temperature on this amps. I want to check the temperature after a long period of playing and check how far well I am within the recommended operating temperature.

Any takers

I don't know what the temperature is...never checked, but I know a rule of thumb is if it's uncomfortable to put your hand on it for a say like 30 seconds, it's probably too hot.

My 1090 gets barely warm, now it's sitting out in the open with just a PS3 sitting on top of it., the 1095 definitely gets warmer than the 1090, but never uncomfortable. Best thing to do is listen to something for an hour with the doors closed... then with them open... if there's a huge difference (there will probably be some difference) then when closed they aren't getting enough ventilation.

Only thing with running them too hot is you lose a little life to them, they are overall made to run warm and often don't sound their best until they get warmed up.

Rotel is pretty specific about the clearances needed for their amps in the manuals. They do not recommend ' stacking' at all. How tightly are they nestled into your cabinet?. Are they stacked in there as well?.

Yes they are specific but one's situation does not always allow the recommended spacing. The recommended spacing is obviously for temperature control but you may be able to get away with spacing in smaller spaces with adequate or no adequate temperature control hence the question on this thread for me and others to know if we are within the optimal temperature
