    I currently have my ProLite 3.0 in a 12 space SKB rack case; but I want to modularize and move it into a smaller 2u rack bag. The amp has vents on the side, and I am wondering if the smaller rack bag will be a problem from a ventilation perspective.

    Is anyone using a ProLite 2.0 or 3.0 in a 2u rack bag, and have experience one way or the other as to whether this more confined rack bag is ok?

    Thanks for reading.

    Rack amps are designed to operate racked. That said I was always happiest with my 2U amps in a 4U rack case. Class D amps don’t generate as much heat as AB so you might well be fine.

    I have a ProLite 2.0 and I recently picked up a (3U) Gator rack bag -- I have another 2U power-amp in the rackbag at the moment, though, and haven't had the ProLite in there. I can't say from experience how much heat would build up in the amp over the course of a loud night of play, but, though the amp is vented on the sides, the main airflow is front-to-back (fan in back) and there should be half-an-inch or more of space between the vented sides of the amp and the sides of the bag. Judging by the 3U case, though, there will be no space to speak of between the top and bottom of the amp and the 2U case.

    I would think that, as long as the front and rear panels are fully open and unobstructed, the amp would be fine. If it were a tube amp I would for sure want more space up top, if not on the sides and bottom. I might be more concerned if the fan/exhaust were on the side.

    Here's a link to the manual: http://peaveycommercialaudio.com/download.cfm?id=16688 It might have "minimum recommended clearance" info re. ventilation (I don't know).

    Good luck!

    Thanks! Yes, I read through that. Doesn’t say a whole lot. Anyhow, in lieu of any experience to the contrary, I’m going to try it. I agree that it seems the main ventilation flow is front to back.

    It'll probably be fine but I prefer 3U rack bags.

    Easy enough to tell if it gets hot.
    How much space is between the rack ears and the amp enclosure, i.e., is there any space on the sides of the amp between the rack case.

    I’m guessing maybe an inch clearance on the sides, due the ears. Top and bottom will be tight, but there’s no ventilation need. I mean, it will probably be fine. I was just curious if anyone else was doing it.
