Orion amp problem ????

Orion amps have small power supplies?
My NT 100 has huge power supplies
Also, the type of power supply is important aswell.
Anything that is Orion, XTR,HCCA,Concept and NT
are extremely well built, some say overengineered,
and I can assure you that the power supplies are
more than adequate. Considering the fact that the
power supply is blowing repeatedly tells me that the
problem is elsewhere, as I said the power supplies
are more than adequate.

As I have said before... The ORION amps have very small power supply's
in them... This makes the amp have to work much harder to get the same
power as one with a bigger power supply.. That is why you are blowing
it... The fans should help but what you might want to try doing is
turning down your gain... Remember, the gain is NOT a volume control for
your amp. I know a lot of people who think it is... Give it a shot and
see what happens...

Are you sure it's the power regulator dumping the heat???

I believe that anyone worth his salt can design a switching
power regulator that can protect itself. The advantage of
switchers after all is the lack of correlation between power
and size, their efficiency, and the voltage boost we need in
the 12V world. Smaller supplies are designed daily by doubling
the switching frequency or just by using surface-mount components.

Power supplies have a circuit called "foldback protection" which
actually lowers the supply voltage to limit the maximum current
and overheating that can be drawn under normal operation.
"Working harder" should be limited to the audio output section.

One thing that can drive a switcher into oscillation
and overheating is resistance and impedance in the ground wire
preventing the input filter from dumping noise, or a
manufacturing/component defect.

I can't tell that from here without looking at it. But, Orion
does have a web page... #

Ultimately, switching power supplies use Class-D circuitry and
may even use IGBT mosfets[1] which translates into heat dissipation
you won't be able to feel.

IGBT: *VERY* low turn-on resistance and heat dissipation for
a transistor.

Maybe you should tell that to Richard Clark :o). If I remember right, he
had motors attached to the gains of the amps in his GN that physically
turned down the gains of the amps with either the volume control or the
noise gate (or maybe it was something else; it was a while back and I'm
working on memory). Does anyone else remember this or have I been smoking
too much crack? :o)
