Denon 3300 Fan Workaround?

I am using a Denon 3300 in a 2-channel setup and find the fan (which begins cycling on and off around 45 minutes after startup) to be really annoying. In addition the metal case clicks as it expands with the heat. My question is this: If I attach a power amp to the "pre-out" connection and use only the 3300 pre-amp, will the heat/fan issues go away? Would the pre-amp section generate enough heat to trigger the fan? Thanks for any input.

Re: Denon 3300 Fan Workaround?

The preamp section will not generate a great deal of heat. Try it and see...leave the amp running with signal going through it and the prein-out jumpers removed and see what noises it makes over time

Why fan stop working

If the fan is not working, it could be the fan itself, or it could be missing the voltage to drive it. I wouldn't use the amp with this condition, as you may cause output failure. If you need more information, or would like to inquire about a repair, please visit my website at You may contact me there. Thank you.

Crown amplifer does not work

Check your filter caps and your drive transistor On that channel that will also fix fan problem unless fan has problem of its own

How to wire Denon AVR 5600 as a separate amplifier in an existing system with a Pioneer SC-57

Do you mean for just 2-channel or what?

The Denon doesn't care what's upstream of it. CD players, other receivers, whatever. The Pioneer has analog pre-outs so you can slave any amps analog input(s) (except PHONO) to any channel(s) on the Pioneer.

Playing too loud music has blown my amp

maybe because your amp is overload, try to load 8 ohms single speaker per channel, then try to playing loud, if blown your amp again, the power transistors bias maybe excess to 0.6V ' if transistorized, if IC power amp, check cooling fan.

I've changed my system around with new products and was trying to get the bb275 to operate with my new Denon 2011 2-zone receiver. Thing is when I connected everything zone 2 just would not operate. I'm...

Are we to assume it was working before the move?

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

I have a denon pma 500v amp, has distortion in right channel, both speaker output and headphones, what should i check for first?

Just have a look around first. Remember the left channel will be the same as the right, so if it doesn't look the same in the right as the left you have the cause of the problem. Resistors are good at causing it, but transistors can too.

Hi all i have a Denon DRA 455 with Eltax Linear 6.5 wich is 8ohms i have a sub but no sub output, apart from sharing power between them, how can i hook these up please? thanks

You did not state if your sub is a powered sub or not, but if you use the "B" channel for your sub, it should work. This is possible if the denon will work with "A" channel and 'B" channel on together. The back of the Denon should have two sets of speaker outputs. Connect the "B" channel speaker outputs to the sub. The "A" channel will still drive your 6.5's.

I have a crown ce 2000 watt amp. channel 2 keeps turning off

Do you get any Fault indications?

Have you swapped the speakers around to eliminate them as external causes?

When the channel dies is the unit very hot and is the fan turning very fast (it should be if hot)? The fan could be defective, slow or airflow may be restricted.

Turn the amp off and examine the fan guard on the rear to make sure it is clear of dust and debris. Vacuum it out if necessary. With a small thin non-metalic object reach in and test the fan for free movement by trying to rotate it. It should coast.

Hi waveybnc

The fan has failed, or is clagged up with dust. Remove it and clean it first. But best to just replace it. They are not that special and there is not alot that stops them from working. You can get a replacement device for the amp from Crown direct, or once you know its dimensions and power requirements, from here.

Thanks for using FixYa. Please rate my advice to you here as FixYa if it helps you.

The hum is power line hum ( 60 cycle ) . It may be that when the amp gets warm that something in the case wants to vibrate to the 60 cycle hum.

I have amps that hum like that and theyre fine.

Depending on the design of the amp, the cooling fan may not go on till it gets really warm in the amp. Some run all the time like the Ashly I just fixed
