DSP problem This unit only works in the Direct Mode or in the Stereo Mode if the Tone Defeat switch is activated. Additionally there is no output signal going to the subwoofer. Sound comes out of the front speakers only in these 2 modes only. Everything else is dead. This is the most complicated receiver and remote I have ever used and being an older person I have either really honked it up by pushing the wrong buttons,(it used to work),or the DSP electronics may have burnt up. I have tried about everything and the manual is no help and way over my head. If it is possible the DSP electronics are burnt up would it be cost effective to fix it or should I just buy a new unit? I hate to spend $100 to have someone look at it and only tell me that it will be a couple hundred more to fix it. Help, Thanks.......

Pressing the PROCESS button opens up the various screens that determine the signal path setup and that control processing parameters for the DSP modules: I/O, PEQ, XOVER, DEQ, DELAY, and LIMIT.
I/O
The I/O module sets up the signal routing inside the DSP from input to output. Press and rotate the SELECT encoder knob to choose between dual mono, stereo, bi-amped, or bridged routing options.
STEREO
STEREO mode routes the signal from both the A and B inputs through a single series of DSP modules. The parallel DSP modules process the A and B signals with identical, linked settings (only module "A" parameter settings appear on subsequent DSP module screens).

Be advised that the engagement of any device in a Tape Monitor loop on a late-model Audio/Video Receiver will effectively tie the receiver down to stereo-only analog sound reproduction. I'll explain.

The connections themselves are fairly simple but it pays to understand what happens in the loop.

In general, any Line-Level external processor (EQ, dynamic range expander, etc) will go into a Tape Monitor loop on a receiver. A Tape Monitor, when engaged, sends the stereo analog signal Out to the Processor, massages it and returns it to the receiver via the Tape Monitor IN connectors to be passed on to the receiver's internal processes (volume, tone, whatever).

Old school analog stereo-only receivers consistently work this way. Newer digital and audio/video receivers introduce a couple of problems: 1) digital sound processing to simulate a variety of soundfields; 2) multiple output channels, either discrete or digitally-generated.

The latter requires that whatever signal is being processed experiences a maximum of one analog-digital-analog conversion.

EVERYTHING analog coming into the modern digital receiver is automatically converted to a digital signal for internal processing unless you choose some form of STEREO-only or STEREO-Direct setting. Consequently, no further external analog-digital conversions would be allowed if, say, a Tape Monitor circuit was activated, and a possible feedback loop could otherwise be created in a digital-sourced selection (output to its own input), so the unit is wired to treat the Tape Monitor as the first analog step in the process and defeats any pure digital sources.

In a multichannel unit, what would happen to the other channels if you sent ONLY the Front Left & Right out for processing? The rest would NOT be processed. That logical problem also plays into the decision to defeat digital sources if the Tape Monitor is activated. I don't totally agree with the engineers but that's the way it is. Nature of the digital beast.

I assume you have it connected traditionally in the Tape loop and understand how that works. ANY 2-channel analog source will work with the EQ engaged.
I'm guessing you have digital sources you want to process. Ain't gonna happen. See page 19 of the manual. Note at the bottom.

Part 1

Let's establish a couple of things first.

1) You already have the turntable part working.
2) Your receiver has a defeatable Tape Loop.

Okay, back to the hook-up: Receiver Tape- or VCR Out to the External Processor (EQ, whatever) Preamp-, Amp-, Tape- or Rec-In; Receiver Tape- or VCR In from the External Processor (EQ, whatever) Preamp-, Amp-, Tape- or Rec-Out.
If you actually want to use an analog recording deck you could place it within the typical Equalizer's own Tape Monitor loop(s). Many have two to facilitate equalized dubbing between decks.

Is this only when using external inputs? The manual says the Tone Control will not function in Direct Mode. Try Stereo and various DSP surround modes to see if the Tone Control works.

You can try this reset precedure below, but it sounds like you may have a DSP board problem. This is a new model of Denon, it should still be under Denon's warranrty, it has a 2 year warranty. If this does not help, you need to take it in to be serviced. If it is not under warranty, you will not like the cost of the repair. A new DSP board usualy cost about $300 and then you must pay for the labor. It is not cheap. This reset procedure has been know to work some minor miracles, lets hope it works one for you.

1. Switch off the unit.
2. Hold the following STANDARD button and DSP SIMULATION
button, and switch on the unit.
3. Check that the entire display is flashing with an interval of
about 1 second, and release your fingers from the 2 buttons
and the microprocessor will be initialized.
Note:��If step 3 does not work, start over from step 1.
�� All user settings will be lost and this factory setting
will be recovered when this initialization mode.
So make sure to memorize your setting for restoring
after the initialization.

If DIGITAL sign blink, this mean DSP board is defective. It will cut the sound on the AMP section. DSp is maybe defective.
