Denon 1612 shutting down!!!!

[fusebulb]

Hi friends
I have my 2 speaker setup of KEF Q500 and Denon 1612 AVR, everything was all well, until i decided to throw a party at my home, and decided to play my system with higher volume, everyone was having a great time, then suddenly within half an hour the AVR stopped and red power light started blinking, i figured the AVR had heated up very much but only after 30 minutes of playing after spending almost 78k for the setup i cant even play loud music for more than 30 mins ...

ok enuf whining, what i want to ask u experts is that is this normal, do i have to get Stereo Amp to listen to hours of music, i dont mind investing a lil bit more for a Stereo Amp if that is the case ... but another question arises is how do i connect a Stereo Amp and AVR both to one pair of speakers ... any suggestions or solutions.. sorry for a very noob question ... i am new to this...??

There are a lot of quality issues with denon these days.
Seems like you have blown something from the power supply or the amp section. Avoid running the avr in a cabinet which doesn't have enough ventilation

For your last question U need a speaker switcher for using same speakers with 2 amps

It must have been quite frustrating.:sad:

I mean after investing 78K for the system the minimum one should expect is countless hours of music nirvana at high volume.

Few months before I had the opportunity to hear music/movies for an extended period of time through Marantz SR6003 at high decibels. Must admit performed flawlessly.

Very recently my friend bought a Yamaha AVR, RX-V667 to be precise & though it is cheaper than SR6003 we listened to music through Yamaha NS-8390 floorstanders for more than three hours at 60 to 75% volume levels. AVR became very hot but there was no problem of shutting down.

Never got the opportunity to listen Denon gear. Quite sad to hear they have such levels of quality problems causing such major failures.

If your AVR is within warranty I think the time has come to sent it to the service center.

Hope you all the best.

if its under warranty, you can get a replacement, do let us know how its resolved, or you got a replacement, it would be good for denon owners like me

Personally I believe HEAT is the biggest killer for amps & AVRs. Heat can cause thermal breakdown, blown power transistors, etc. Excessive heat generated inside the amp can cause rapid reduction in life of the electrolytic capacitors used in them and also cause them to explode or dry up early.

I also wonder if these amps/AVRs are optimized for our Indian climate or not. This is the reason why I did my personal DIY and fitted six CoolerMaster fans over my 7.1 channel Yamaha DSP-A2070 integrated amplifier.

There are times when my apartment is empty & my friends are in for a party, this amp blasts for quite extensive periods(8 to 10 hours) to say the least at high volumes. The only obstacle that prevents my DSP-A2070 from being a glowing oven are those six fans expelling hot air magically transforming it to a room heater.

I believe something went ka-putt within the AVR ....... high voltage, fluctuations can be the major cause, was the AVR, connected directly to mains .... ???

I like your signature line Rishiguru. 'I Am a music lover,not an audiophile'. Applies to me as well.

Thanks jaudere.

thanks for all the suggestions ...
the AVR works fine otherwise, at low db levels it does run for hours only when my LCD TV is connected, my HTPC with sound card is connected and if i play at high db levels it gets heated up and shuts down, it's a relatively new AVR not even a month old...

@sam9 no i dont think there was any damage to the AVR because after cooling down it again starts playing, only problem is it gets heated up pretty quickly within half hour of loud music ... i suspect the compatibility between my denon and the speakers...

But after spending so much money and then hesitating to increase the volume to play my fav numbers is not done man....

does anyone know if my Denon 1612 is not powerful enuf to drive the KEF Q500, i dont understand the tech spec ... will buying a dedicated Stereo Amp solve the problem ... and what Stereo Amp would be recommended for the KEF Q500 speakers but within budget ... i dont want to spend too much money again and then be disappointed...

 

[spirovious]

Check the sensitivity of speakers.Kef can demand more power & Denon 1612 is entry level AVR.Cant sound loud.

 

[rishiguru]

The KEF Q500 have an impedance rating of 8 ohms. All AVR's in the world support 8 ohms in general.

If the floorstanders were rated at 4 or 6 ohms, massive overheating would have taken place in your AVR provided they are not designed to handle 4 or 6 ohms load.

Quite fishy here. Seems to me a manufacturing defect.

If your AVR is ok, and this getting heated up & shutting down happens to be a normal phenomenon, I have to admit Denon makes crap AVR's having loads of Sh!t.

Nothing against Denon, but if this be the case for me I would have thrown this AVR out of the window by now.

Marantz, Yamaha & NAD. All three are good having different sound signatures.
Audition & pick yours.

By the way do your Denon gets properly ventilated?

I mean do you keep it in a rack where there is at-least 2 to 3 inches free space on all sides of the AVR in order to let the heat escape?

 

[jaudere]

Cost cannot be equated to power. Cost may be high due to features or sound quality also. So being unable to play loud music after 78k is not a valid point. A mercedes cannot do the job of a Tata bus(carrying a lot of people ) despite costing a lot more.


I dont know of any Avr that is meant to be used to play loud music at parties.
I would rather buy a simple good power amp, connect it to pre outs of the denon( i hope it has pre outs) and connect it to the KEF speakers on day of party and then shift back to original set up for routine use.
A simple public address power amp(even a mono amp) should be suffice for party use. In a party, quality takes back seat and quantity is the driving force. No one is bothered about imaging/soundstage/surround effects etc. A clean thumping sound is enough.

well with this one off incident lets not make the whole denon brand bad..I am using it for quite long, no issues at all, dont use floor standing speakers though, on the other hand I read a lot of incident on avsforum about onkyo getting heated and they did some technical tests which proves onkyo heats more than denon, with even this I am not against onkyo, its a good brand

and yeah if its happens regularly and you can show it to ur seller at ur home that it shuts down under a scenario and its under warranty, I am sure you will get a replacement or a solution...

Sorry boss, just got angry thinking about it.

I love to listen loud, and if this shutting down was due to a failure, then that was ok. But as fusebulb says, this happens to be the natural phenomenon of this AVR. Complementing this fact that the speakers are only 8 ohms, the situation becomes quite unbearable.

its ok mate I can totally understand how frustrated we will be if after spending so many bucks the stuffs dont work fine and break down

and happy new year to all here guys

..I am using it for quite long, no issues at all

Do have the same model?

dont use floor standing speakers though

Whats wrong with floorstanders? Kindly explain.

am using 1312 and use my avr for almost 10 hrs daily also while playing movies at quite loud volumes, and in terms of power specs 1312 is same as 1612.

and I mean I don't have floor standing speakers, absolutely nothing wrong with them

 

[fusebulb]

yeah, i tested it by playing King Kong 3 hrs movie at decent sound, no problem, i played it from my PC via HDMI from the Graphic Card, the music is generally played through the coaxial from my Asus Xonar Essence sound card, i use foobar player to play my songs, strangely it produces more heat if i play music from the sound card and the AVR shuts down, but it plays my movies fine even a 3hr movie .... strange ...

P.S. Though it does play music for long if played at medium db levels
