Hi

Can anyone tell me if it is normal for the Denon DN-X1500s to get very hot during use?

So far we have used it without a flight case but our new coffin case arrived this morning and we are worried that it will get even hotter once its in the case!!

What type of case is it?

Just make sure it has plenty of ventilation so the heat can dissipate....
Blimey.....:eek: did I just say that.;)

All Denon mixers seem to be like that Sarah - the power supply is right underneath I believe. I've had a 400 and 500 and both ran fairly hot.

Yeah, all the newer Denon mixers operate at a higher temparature. It's quiet normal, due to the digital circuitry, just the same as a computer motherboard really.

Thanks everyone, I will tell my son not to worry.

The case has just arrived, it's an odyssey glide style coffin and it weighs a TON!!!
Lucky Phill is older now and can lift his own equipment because there is no way I am lugging that thing around!:eek:

Its down to cutting corners in the power supply like cheapo small transformers. A mixer doesnt take that much power so its quite feasible to design a power supply that doesnt get hot.

I can design a 1000WRMS amp that doesnt fry at 10 amps so I am sure someone can design a mixer power supply using 1 amp not to cook.

A niche in the market for you there Nigel

Maybe its hot to keep the DJ's hands warm ?

Remember it has an on-board sampler, effects unit and digital matrix input.

I dont agree at all.
I have been designing electronics for 30+ years and never had heat problems.
Adequate heatsink, ventilation and fans means overheating should never happen.

Also bear in mind if it is getting that hot then the thermal cycling wont do the electronics any good at all.
Also electrolytic capacitors dont last as long in a hot environment.

Sounds to me like they just need a few lessons in electronic design !

Yeah, I'm sure Denon have no idea what they are doing...

Of course they know what they are doing.
Thye are designing stuff as cheap as possible to maximise profits !

Denon and Pioneer (amongst others) don't operate at the 'budget' end of the market, and rely on their reputation for manufacturing quality, reliable equipment. Of course they have to design within a budget, and with a target retail price, but I can say with no hesitation that they would not compromise on key components.

But they arent charities they exist primarily to make a profit.

If they make 1,000,000 units and save a penny on a resistor then that is £10,000 saved.

So if they save £1 on a cheap heatsink ?
You do the maths !

Ive had this mixer a year and used it for all my gigs some lasting as long as six/seven hours. The heating thing does worry me abit but ive never had any proplems with it! I have it sat on top of its metal flight case but i would be abit worried about putting it in a coffin case. Saying that i love my denon equipment (got two dns3500) and its quality throughout despite what Nigel says.

IMHO Denon make rather nice mixers, the rotary channel matrix is very innovative and they are well laid out. We have sold quite a few of them and also have used them on installs - never any complaints from the DJs.

A mixer shouldnt run hot.
A amp maybe but not a mixer.

Having said that semiconductors can run upto 150 degrees C.
But that doesnt mean you should be frying your hand on it !

Big expensive heatsink, less heat. Small cheap heatsink more heat.

So your telling me my mixer is also a hot plate?? Awesome! Another reason to buy Denon ;)

Silvio Zeppieri from Denon (Username Denon) is actually a member, although he only usually comes on here when there's something to promote.

Hook it up to some Mackies, and then it'll seem a lot cooler:sofa:

the denon mixers usually take about 1 Motown Track to boil an egg with a nice runny yolk
If you like them extra hard, then i recommend 1 meatloaf track

Cool. Wouldnt it be good to have all the major players on here promomting/informing about their stufff. Or am i in cuckoo land :)
