SOURCE: Denon PMA-520 amplifier clicking noise

Sounds to me like a bad capacitor, but not sure. I would look inside for any slightly bulging capacitors or capacitors whose plastic wrappings have melted or shrunk or cracked (most caps are cylindrical). Please unplug first and be careful inside there and do not touch anything. I actually came across your post while looking for info on what I think is the same amp my brothers had but blew, and I was going to ask if they still had it so I could repair it. I've been very successful at repairing my electronic equipment such as Altec Lansing Model 95 speaker crossovers, power supply in Emu Emax II, and almost everything else in my studio.

How can I connect a subwoofer to this device (denon pma-520) http://www.hifiengine.com/manual_library/denon/pma-520.shtml?destination=node%2F14208


Look around for a subwoofer which has speaker level inputs.
Something like this;

The only safe way to do this us to connect the sub to one of the other speaker outputs using a "speaker selector" switch. For example, you would go out of the receivers left speaker output, into the selector switch then out of the selector switch into the sub and the left speaker. There really is no other way.

Hi, i have a Denon PMA 735 R amplifier which shuts down when volume increases suddenly.


Sounds like you have output transistor problems. Does it have a red protection light that comes on when it shuts down? If it does it will need serviced.

I have a Denon PMA 500V amplifier. all of the output fuses were blown so I replaced them but the unit still doesn't work. Any suggestions?


hi.
Did you checked balanced impedance?load speaker impedance vs PA output?or PA might over driven,causing a trouble on the pre-amp to power amp circuits and components damage,
need to recheck related components on the pre-driver up to main output section,

Note: That,blowing of fuses with the same rating is an indication of trouble/shorted in a circuits that driven on it,

Thanks and good luck

My Denon PMA-900V integrated amp has distortion in the left channel. When it is cold it is very minor, as it heats up and is played at louder volume the distortion is much worse.


The good news is that it's in one channel, which means you have the right channel parts to compare it with. Now the bad news whatever causing it and it's likely to be a semi-conductor (transistor or IC) has to be replaced. However finding it is easier than you might think. For a start it's going to be hot to touch. And you can get get it to stop being hot, while the amps on, so correcting the fault, for a while. You do this by spraying it with Servisol Super Freezer spray. You have to have the amp running for this. Find the left channel amp and wait while it goes bad. Then spray (one at a time) any part you suspect. If the sound returns to normal, you have found the faulty part! To prove it spray the same in the right channel. That shouldn't change.
You can get the freezer spray from your local electric parts shop (such as Maplin UK).

Denon PMA 700 AE maximum phono input signal


Why? Are you contemplating connection of something OTHER THAN A PHONO CARTRIDGE to it?

Be advised, only a phono cartridge should be connected to a Phono input. There's more going on behind it than just voltage step-up.

Deneon PMA-250 amplifier -Volume knob not working correctly


Well, it seems you have your finger on the source of the problem. If accessible, try some tuner cleaner inside the potentiometer.

My aplifier Denon UDRA F-10 says "protect"


Blingking Light or Protect usually means that there is DC appearing in output stage and is protecting Connected Speakers.
It can be faulty Output Stage (Bad ICs/Transistors/Resistors/Capacitors) or Faulty Power Supply.

Working on These types of Problem is not user friendly at all.

Advising to take local Authorized Shop.

DENON Input selector jumps randomly


I have a PMA-535R. Same problem but slightly different dialknob. I fixed it by spraying a contactspray and WD-40 into the knob itself. This does mean you have to disassemble the front of the amp and take out print of the dialknob. The knob has a plastic dustcovere that you will have to lift. Good luck
