Ok I recently purchased a new receiver (Pioneer VSX-D814) and its my first nice receiver (with more than 4 speakers) and I would like to know, how much heat is allowable?

For music I will typically have 4 speakers running, two towers, and two bookshelfs, both are set as "fronts" just on A and B so I run A and B together and it gets fairly warm.

It does this no matter which speakers, or configuration i use

anyways, its warm, I can easily place my hand on the metal grill on top without it burning or hurting but there is definite heat (even when run at lower volumes, though the heat is not as much). So is some heat normal?

Thanks all


P.S. The grills are not covered by anything and it has about a foot between its top and the shelf above it so plenty of clearance
