Question about Audio Players & Recorders
Unit mysteriously switches to and from HP on/off serious hampering any enjoyment of trying watch/listen to anything thru receiver
If you don't want to use the headphone jack, then you can take the top cover off and look at the headphone jack board. There should be a cable that can be unplugged from there. This will disable the headphone jack and take care of this problem. This is very common in these models. If you need to be able to use the headphone jack, then the jack will need to be replaced. Denon now has an improved jack that can be installed so this problem doesn't reoccur.

SOURCE: Denon AVR-1601
This is a very common problem with denon receivers of the 2001-2-3 vintage. On almost every one, there are 4 little "surge" resistors in the power supply. These werent quite robust enough from the factory and one day would just burn open for no reason. Well, actually there is a reason, the "surge" that happens every time you power the unit up eventually weakens the resistors and then they pop. You need to take this to a denon service shop as I GUARANTEE they have seen this before. They need to check resistors in the picture, locarde above the **** rectangular connector. Resistors numbers R141, 142, 148, 149: These resistors when measured, should be less than 10 ohms each. If they are more, then they are blown. If they are blown, then have the shop check the channels for blown output transistors. If the outputs are OK, then these resistors should be replaced with 1 ohm 1/2 watt metal -film flameproof resistors. You might need to be prepared for a large bill, because the entire unit must come apart to replace the resistors, however, just checking them takes only about 10 minutes... Good luck and don't try this at home. Rob

It sounds like you have a bad speaker on the zone 2, or you have the speakers connected improperly.
When you engage the zone 2 a relay clicks and the speakers then become part of the amplifiers circuit.
If the problem was in the amplifier, it would go into protect mode without even having speakers connected to it.
If the speakers all check good, you most likely have the wrong type of speakers, meaning the impeadance is too low, or you have too many speakers connected to it.
On the back of the Denon, you will see right around the speaker output jacks, what ratings the speakers should be. If I remember correctly, it says 6 ohms or more when using only "A" or "B", and it says 12ohms or more for "A" + "B".
If you have two 8 ohm speakers on the same speaker jack you now have a 4 ohm load. That is below the ratings and can cause the amp to shut down (go into protect). Since your amp shuts down right away, I think you have a bad speaker or way too many speakers connected.
I have seen many times when people will connect 2 or 4 speakers to the one of the outputs that are designed for only 1 speakers.
If you are using too many speakers you will need a speaker distribution box. It has a resistor network built into it so the amp never sees a lower impeadance than what it is designed for.
You can connect 4, 6 or 8 speakers to one set of outputs designed for 2 speakers. You do loose a lot of power to the speakers, but it is better than blowing up your amplifier.
If I can be of any further help, let me know.

If your TV has an HDMI input, hook up the PS3 w/an
HDMI cable to the TV. This will give you a high def picture (set up the
PS3 to output the max resolution your TV displays). That will take care
of the video side.
Next hook up an optical cable from the PS3 to the receiver. In the PS3 menu, you have to change the audio settings to output the sound via the optical cable.
Finally to get sound out of the receiver to the speakers, you have to setup the receiver source input. For example if you setup the PS3 to play thru "VCR" input, then you have to make sure the VCR input is setup to use either optical 1 or optical 2 for sound (whichever one you have the optical cable plugged in from the PS3).

There are three modes (Auto, DTM, and PCM) on the input mode switch, on the main unit, selected by repeatedly pressing the input mode switch.
However, if you have already depressed the Analog button in, on the main unit you have predetermined the mode as analog.
On the remote, the INPUT MODE switch combines toggles for 5 choices, [Auto, PCM, DTS, Analog,
My guess is that either the input mode switch on the main unit and/or the remote are toggled to analog.

even if the wires are not touching they can still arch. make sure there is no bare wire showing ie. cannot see any unshielde speaker wires. id unplug then replug back in
