palbin Posted March 18, 2008 Share Posted March 18, 2008 hello! can I run Behringer 2500 amps up side down (to get cables in right place compared withother amps)? best palbin Link to comment Share on other sites More sharing options...
J Pearce Posted March 18, 2008 Share Posted March 18, 2008 I wouldn't recommend it. PCBs usually reside at the bottom of a unit as that is the coolest part, flipping the amp over puts all the delicate components in the hot bit. Link to comment Share on other sites More sharing options...
adam2 Posted March 18, 2008 Share Posted March 18, 2008 I would also advise against upside down use, apart from the thermal issues noted above, undue mechanical strain could be placed on PCBs by the larger components, if the equipment is used inverted.

The Boogie Man Posted March 18, 2008 Share Posted March 18, 2008 Go on, I'm curious. Why would inverting a 2500 make any difference, the outputs on mine are verticaly alligned and centeral so inverting them would make no difference. Other than moving the inputs to the right, for this reason?baz Moderation: Quality Control: You clearly haven't read posts 2 and 3 in this topic which give two reasons not to invert a power amp: thermal issues and possible mechanical stress.

J Pearce Posted March 18, 2008 Share Posted March 18, 2008 Chappie I did say 'usually'. I am aware of exceptions to the rule. Link to comment Share on other sites More sharing options...
The Boogie Man Posted March 18, 2008 Share Posted March 18, 2008 I think moderation didn't read my post clearly as I asked what difference inverting a 2500 would make. ( not any amp ) ;) As a 2500 is laid out almost cemetrically, upside down is almost the same as right way up. Link to comment Share on other sites More sharing options...
palbin Posted March 18, 2008 Author Share Posted March 18, 2008 Hello! I am planning two more or less permanent rack piles - pretty high - there all amps have electrical power supply in on the left - speaker cables out on the middle and signal in on the right (loocking from the backside) - the Behringers though have this mirrored - power in on the right and signal in on the left - also all other things I have have power supply in on the left - so I am planning to do a very tidy drawing of cables with cables of exactly right length - power cables routed on the left side - speaker cables (in case of amps in the middle) and signal cables on the right - but theBehringer amps makes irritanting resistance to these plans! That's it! Could I turn them upside down (placing rubber shoes on the top of them instead of bottom) this would resolve itself though!

johnhuson Posted March 18, 2008 Share Posted March 18, 2008 As a 2500 is laid out almost cemetrically, upside down is almost the same as right way up. Not entirely true, if you look at this picture you can see that whilst the outlets are fairly central, the signal input is on the left and the mains on the right hand side. If everything else in your rack is the opposite way round then I can see for reasons of neatness it would be nice to have the EP2500 upside down, but I concur with other comments that it's probably not a good idea for a number of reasons. Aside from that, whilst it would mean it was a neat rack from the back would just look clearly weird from the front. That might not be the OPs reason for wanting to run it upside down, but it's the only one I could come up with! EDIT Beaten to it again! Link to comment Share on other sites More sharing options...
The Boogie Man Posted March 18, 2008 Share Posted March 18, 2008 I figured that might be the reason, as it's the only physical difference. It's really annoying to have one odd bit of gear in a rack, especially if your as sad about neatness as I am ;) Link to comment Share on other sites More sharing options...
KevinE Posted March 18, 2008 Share Posted March 18, 2008 PCBs usually reside at the bottom of a unit As in the Behringer. I agree with all the posts that say it should be the right way up, this is no doubt the way the design would have been life-tested in the factory at design stage.

Sirch Sound Posted March 18, 2008 Share Posted March 18, 2008 especially if your as sad about neatness as I am ;) Not sad in the slightest. A tidy rack is ALWAYS a better rack, for so many reasons. Problem solving is so much easier when theres not "balls" of cable lying in the bottom of the rack. It looks much neaster.It eliminates any interfierence problems with power and signal cables together.Its much easier to dissconect and add gear to your rackOptimum performance of cooling of your gear.

boatman Posted March 18, 2008 Share Posted March 18, 2008 With a few bail bars and a roll of lacing cord any rack can be made to look tidy inside. It should also look tidy from the outside and mounting an amp upsidedown will detract from that quite severely. Link to comment Share on other sites More sharing options...
