My HT-R510, at times, loses it's sound settings

One way would be to connect one of the the digital audio outputs to the HT as an input (HDMI or optical digital audio).


Another would be to select one of the DSP modes that uses surround speakers. They work with all input modes.

Hi amstok

Sounds like it may have a DSP failure. Straight stereo signals bypass the DSP stages. Could be an expensive fix. I suggest you take it to a Hitachi agent for a quote. Not something that can be easily fixed on the kitchen table I am afraid.

Try selecting different options for the DSP audio settings. Sometimes a simple 2 channel stereo with subwoofer gives the best dialogue intelligibility. I would avoid fancy reverb presets like auditoriums and churches etc. You probably want to find a nice balance between the dialog, the music and sound FX, and the bass (subwoofer) BEFORE YOU START MESSING WITH THE surround speaker FX. Also, you may find that you have to readjust all the settings for different videos. I finally just opted for the simplest, no-fuss approach. Usually the stereo with sub. For really good concert DVDs, you will probably want to use all the speaker configurations that 5.1, 6.1, and 7.1 support.

Are all the speakers turned off (set to None) in the speaker menu.(except the sub)?

2 channel direct analog stereo may still work, but any surround modes will use the speaker settings and the full DSP digital section.

Check also the input mode isn't incorrect - although if the sub is wired correctly and gives sound this can't be whats wrong.

to determine if all the amps are working use the 7.1 direct in jacks, insert audio into each jack if all works then you have a defective surround sound assy also know as a dsp board..

DSP modes usually act on ANY input source, including stereo. Are you saying you have no surround speaker fucntions? Get in the setup and define, then adjust them.

Might be over heating. Make sure you don't have anything sitting directly on top of it. I even put a little fan blowing outward at the back of my system to keep it cool.

THE BEST SOUND IS WHAT SOUNDS BEST TO YOU, HOWEVER DO THIS:
1, USING THE SETUP MIC CONFIGURE YOUR DENON, PAGE 8 OF THE MANUAL. NEXT
2. RAISE THE REAR SPKR LEVELS, PAGE 46,47. NEXT
3. WHEN LISTENING TO AUDIO CD OR RADIO TRY THE 5 CH STEREO DSP MODE.
4. WHEN WATCHING A DVD USE DSP DOLBY PROLOGIC OR TRY 5CH STEREO IF THE MOVIE IS MOSTLY TALKING.
5, TRY 5CH STEREO WHEN WATCHING PROGRAMS WITH MOSTLY TALKING

Hi...
Is the first set "stereo" settings and the 2nd set "surround" settings?
If so that may mean that the surround speakers arent all connected right.

The P.BASS function is only available with 2 channel LPCM sources such as mp3,Divx,cd
and wma. Press P.BASS button and "POWER BASS ON" will be displayed on the screen.
The P.bass does not work with DSP/EQ or DOLBY PRO LOGIC ll modes.
If you press P.BASS in the DSP/EQ mode, the DSP/EQ mode is automatically shut off and the P. BASS function comes on.
The DSP/EQ function is only available in STEREO mode.
Press the PL ii mode button to show STEREO on the display.
This feature works with CDs, MP3-CDs, 2 channel DVD-Audio, DivX and Dolby Digital discs.
When playing a DVD disc encoded with two or more channels, multi-channel mode will be selected automatically and DSP/EQ function does not work.
