This is a simple question with a yes/no answer. Can the internal amp be turned off? I checked several seller pages and Pioneers page and searched but didn't come across any answer either way.

Thanks and merry X-mas

i do not think pioneer's can do that. IF any pioneers can do it,it has to be the premire's or the ultra high class ones.

To my knowledge Pioneer does NOT have this feature in any of their decks as of the 04 models. They might have them next year since this is becoming a popular demand for decks right now.

Yes, the 860 has 24 bit burr-brown converters :D

The DEX-P9 has NO internal amp. It has pre-amp outputs and a digital output. No power.

There's no need to turn them off. Just leave the speakers disconnected. Won't hurt anything and doesn't draw much power without a load.

Yes, this is true. However, even if there is no load on the internal amp they will still generate unwanted heat and from reading other posts by you (maylar) I'm sure you know that the cooler the better when it comes to electronics. So anytime I can eliminate some heat I would like to be able to do so. I guess thats my opinion on the subject.

The amount of additional heat from the internal amp will be extremely small. The CD motor will generate more. Just don't short the unused speaker wires :)

Rad. Thanks Maylar for the answer and Adam for provoking him.

Every deck I've ever owned had internal amps (keep in mind I used my int. amp once in my 17 years of playing with car audio) ALL of them have run hot. When I finish paying off and installing my P9 I will check and see how hot it gets and if it gets about as hot as my "amped" head units then I'll bow to your wisdom. But I don't think it will.

I'm not trying to split hairs or anything but if more decks are coming with the feature that lets you turn them off and high end decks don't have int. amplification then it must have a distinct advantage wouldn't you agree?

Not having internal amps gives the designers space to put other stuff like balanced RCA outputs and high voltage preouts without making the HU bigger. In theory there should be a price advantage too for leaving those parts out.

The standby power of 4 amp channels without load should only be a couple watts. Yes, it'll add a bit of heat but it should be insignificant. I agree with you that they get mighty hot when you run speakers tho.

Why some models allow turning them off is a mystery to me. Maybe they figure people will have speakers connected and want to turn them off? Maybe it's just marketing hoopla.

Or maybe I'm fulla ****. Wouldn't be the first time...

my old clarion HU didn't have an internal amp and that thing got hotter than a mother******, the cd's would be hot as hell when changing them. I now have the 860 (which is why i clicked on this thread) and the cd's are barely warm when changing them. So i don't think the internal amp has too much effect on the heat issues.
