And much to my surprise, the fan stays entirely off under normal operation, and Google tells me this is how the thing is designed to work. I think I've found my new practice amp. Aside from sounding great, having zero fan noise in my itty practice room is REALLY welcome. This thing also takes up almost no space. Double win. My only complaint for using this for practice is the lack of a aux input. I've already got plans to wire up a few jacks and resistors into a passive mixer box to blend the effects loop send with my mp3 player output. Problem solved (well, it will be soon). The headphone out seems to work as advertised. Seems silly to practice with a 800W amp, but that's what volume knobs are for. Oh, ya. I plan to use it with the band, too, but I'm just shocked how useful such a powerful amp is for my practice room.
Yeah, these Class D amps run pretty cool. Been playing mine for years and they have barely warmed up if at all.
I've owned (and still own) other class D amp, but this is the first one I've used that totally shuts off the fan when running cool. Very clever.
The fan on mine would come on after a while when the amp was not even being played through and it's LOUD!
Interesting. Other folks say that their fan almost never comes on at all. I wonder if their temperature sensors vary significantly from part to part.
Oh, yes. I win. It wasn't my intention to use this for practice, but this seems awfully convenient for it. I guess this will really be my "everything, including practice" amp.
Just get ready OP, you'll end up going "Well of course I HAVE to get an MB200, it has the Aux Input! Hmm, I wonder if 2 GK Neo 412 cabs will be enough for a 30-person coffee house gig...better get 4 just to be sure." The GK stuff is pretty killer, I'd pick them for an endorsement deal over anyone else.
Been thinking about getting one of these. Were there reliability problems with early units? I get that sense from browsing some of the threads about this amp...
The one I bought very recently from someone was a replacement for a failed unit, so it seems to still be occurring. Of course all brands are subject to failure.
Funny thing...I practice thru my lil 15W amp in part because I fear my electricity bill spiking if I started using my MB200. I'd worry an 800W amp would throw a breaker!
The fan on my MB800 comes on after only a moderate amount of playing, and it's definitely noticeable. But I have no intention of using mine for anything other than personal practice, rehearsals and live gigs - no recording sessions. So the fan noise is for me a non-issue. MM
Frankly I'd rather have an amp with a fan that kicks on when necessary rather than an amp where the fan is quiet but prone to overheating... such as my Carvin BX500.
