SOURCE: Receiver shut down only when using phono preamp

Since the protection circuit trips after 4-5 songs at high volume from LPs, it may be that the infra-sonic rumble common to phonographic recordings is driving your amp stages much harder than it sounds like they are driving. You can check this with watt meters for your speaker outputs, or by filtering such extremely low frequencies on the input. If you have an equalizer--especially an old one--it may have an infrasonic filter, or just cut the very lowest frequency available on the equalizer after running your phono pre-amp into the EQ and the EQ into your VCR2 input. This setup will verify if your problem is the infrasonic rumble, but I wouldn't use it as the solution. There are very quiet infrasonic filters available that would work better for the long term. And if you just cut the lowest EQ frequency out, you'll miss some good bass.

SOURCE: shuts off then red light indicator flashes, disconnected all speakers but still wont work

Hi, this is a power board issue. remove the cover and make sure that this unit doesn't have blow fuse. if the fuse is fine, you will then need to replace the integrated power/ main board.

SOURCE: Loud distortion through phono inputs

Phono inputs are designed for turntables only. Any other device will provide too high a signal for that input to handle. The phono input has an extra amplification stage built in. The distortion is because of the high suignal level being supplied to the input. The only way to get this to work properly is to purchase an antenuator which will decrease the signal level to the phono level.

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 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 hands-on tech.


Check for loose speaker connections, too. You need to identify a root cause.

SOURCE: denon avc-3020 amplifier, both rear speakers play

You really need to read the manual and maybe physically rearrange your speakers for that left / right swap thing. Back Surrounds (if that's what you meant) frequently are the same unless the origianl program material has 7.1 sound.

How did the Test Tones fare?

I have an old Denon stereo receiver DRA - 565 RD. Do you know how I can connect my iPhone to the receiver to play music from my iPhone?


You need a 3,5mm male stereo connector to RCA male jacks (see attached image). Plug the 3.5mm jack to your iPhone and the RCA jacks (red & white or red & black) to your Denon Receiver's CD in or Tape 1 or 2 PB (at the rear of the unit). Then select the input where you plugged the RCA to (front of receiver: CD / Tape-2 / Tape-1). Hope this will help. 25303676-z0ul41frrnrex4ege2epffps-1-0.jpg

Denon 2802 amp


Dear Armani,

You cannot put de leads from an MP3 player or your TV into the pre-amplified connection of your Denon,
the phono "stage" is a low input stage, your input from MP3, TV, CD, DVD oscasetteplayer is high output (a 5 to 10 times stronger signal)
Try every other stage like tape 1 or 2, this will work just fine,

succes

Denon AVR 886 only shows analog input


Are your speakers able to handle the 886's power. I have the same reciever and changed by speakers as the Denon would turn off instead of frying the speakers.

As for the digital, have you used the option to change your audio feed and video feed. (for example - I'll show photos through the front input but use the CD -digital for music. Maybe the audio feed is locked onto an analog input. Just a suggestion.

My denon avr-a10se stop working. When I start, aftr thr quick intiation the amp shuts itself and the red power light start to blinvk quickly - please help


This unit is in protect mode. This means that a problem was detected in the last stage of the amplifier section and the unit shuts down to prevent further damage. The most common failure parts are the output transistors. These usually run between $5-$15 each. Add in the local labor rate for the total repair cost.

DVD Audio Output Stops


Hey Kelby,

I've had a similar experience where a DVD movie would be playing and suddenly my Denon would just shut off, I later discovered that my rear speaker cables were not correctly installed in the back so the reciever recognized it as a short and would just shut down. Just make sure your rear speaker cables are correctly installed (right to right and left to left and with correct positive/negative placement) and see if it still does it. If it's still happening, then I wouldn't know what it is. Good luck.

Receiver shut down only when using phono preamp


You may want to try putting an attenuater in the line with the RCA's to cut the input signal back just a little bit. So you are not driving the amp so hard with your preamp.
