Can you leave class D amps on and not ever turn them off?

Hi Ph.D.... YOu are absolutely correct.... I have observed the same thing, and should have mentioned it.


Fact is that with all my amps, class D and class A/b alike, I turn them off once a week for a couple hours for the very reason..... After a week or more days of running continuously, the sound just sags a little bit.... Turning them off for one or two hours and powering them up again freshens them up nicely.


Regards, G.

Ok, I will turn my amp off for a tad and then let it warm up for a couple of hours and see what we get. I assume it still sounds best always on, but just turn it off for a tad after a few days. Strange, but I am open minded.

I know my Class D amp sounds far better after being on 24 hours.

Guidocorona, it couldn't hurt anything to try on occasions as long as you power everything down first. You could actually leave the system unplugged for a few minutes then plug back in. This is a tweak that won't cost you anything.

George can you give us a couple of examples of the ones that go up in smoke?
Ones I remember
Panasonic PVR's, dvd/cd players, Samsung, Panasonic TV's,  2 x Velodyne CHT15 subs, 1 x Alesis 620, 1 x Nuforce 8 monoblock, 1x Halcro DM68 that had to be shipped back to manufacture. 1x Behringer B2031A, 2 x Behringer active xovers. 
These are ones that were left on or in standby.

Many others were blown and popped their fuse but didn't fry up. 
Countless smp battery chargers, some of them liked to fry with much crackle and big smoke.

Cheers George

I hope when their switching power supplies blow they won't destroy the speakers, but I suppose that is why they are protected by a fuse.
