Is the T+A PA 3100 HV integrated amplifier hot to touch? How much ventilation does it require?
@hgeifman The 3100 runs fairly warm. You can touch it, but you will not want to leave your hand on it for a length of time. I have it in the console opening for a center channel speaker with about an inch of free space above it.
For the U.S. market it comes with an Energy Saver feature that can be enabled or disabled. More stringent jurisdictions have it enabled only.
I have left it on fully (not standby) for a number of weeks (multiple times) without any issues.
