Check your blu-ray connection. Is the HDMI cable going from the player to the receiver, then another HDMI cable going from the receiver to the television? What about your TV input? Is there a cable going from the cable converter box to the receiver's input?

Subwoofer


I'm not familiar with your unit. However, this is normal, since the "sub" is encoded separately in movies. I have a separate sub for my front speakers. Or if you know what you're doing you can redirect the front signal to your sub by using a switcher when you're listening to cds, then switch back to surround when watching movies. But again, you have to be experienced in the principle of A/V configuration.

Setup help for record player (Pro-Ject Carbon Debut) and pre-amp (ART DJPRE II) into Denon AVR-1909. I have everything setup properly, but I cannot get the subwoofer to turn on with my 2-channel settings...


In two channel mode, there will be no subwoofer signal unless you change the front speakers to 'small'. If you set the front speakers as 'large' then the full frequency spectrum will be sent to the front speakers, and none to the sub. Switching from bluray may keep the surround configuration until you restart as you mentioned.

Greetings- my denon avr2802 is connected to ps3 for blu ray movies, games and music. The ps3 image goes directly to tv with hdmi and sound from ps3 goes to the denon using digital audio cable. Sound for...


Set the receiver for auto audio input - I think that you are getting caught out between MPEG and DTS audio. If you have the wrong one for the audio source then you hear nothing.

No video on Denon avr 688


After days of frustration the real problem was with the cable box. It needed a firmware update. Following forum advice I disconnected the cable box power cord for a few minutes, reconnected it, allowed the cable box to reinitialize. Turned off receiver and TV. Turned TV back on and set it to HDMI connection, turned on receiver and all worked fine. Great picture and sound.( Needed to buy an optical cable to go from the cable box to the receiver to get sound from the speaker system. )--the dirtybird

Protection circuit momentary activation. Not heat/speaker problem


Is it possible for you to lower the source level? if yes go ahead...

There is an automatic Dialogue normalisation function in Denon which is activated to reduce overly bright input signals. ( most movies have wide variation in sound levels and therefore this function is avaialble). (see page45 of your user manual).

When your system worked fine with the AVR 2808CI, then why is it giving problem with AVR 3808CI....???? You must ask Denon.

Protection circuits are activated when:
1). There is rise of internal temperature.
2).Core wires of the speakers are touching each other or a core wire is sticking out of the terminal and touching the set's rear panel or the speaker itself has a problem.
3). Speakers with an impedance other than specified are being used.
or
4). the set is damamged or has bad solder / dry solder connection .

If your AVR is new, please do not accept, the set could be faulty. The protection circuits should not be activated unless any of the above happen.

You must know, at times the protection circuits are not fast enough and it could burn some of the transistors on the power output circuit. With time, the solders on the circuit board could give way and give you problems later on.

You must sort out with Denon if the AVR is under warranty.

Best of Luck.

Problem getting the best surround sound when watching a dvd


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

Denon AVR-688 Dolby Digital issues


IT IS ALWAYS BEST TO CONNECT ANALOG AUDIO IN ADDITION TO THE OPTICAL, COAXIAL OR HDMI AUDIO CONNECTION. IF USING OPTICAL OR COAXIAL CONNECTIONS BE SURE TO CONFIGURE IT IN THE RECEIVERS DIGITAL ASSIGNMENT AREA IN SETUP.
ALSO, ON THE FRONT OF THE RECEIVER IS AN INPUT MODE BUTTON, PRESS THIS BUTTON UNTIL AUTO IS DISPLAYED

How to connect BLU-RAY DVD player to Pioneer Plasma TV via HDMI


The best possible solution to your problem is :
Connect your blu ray player directly to the HDMI input of you Plasma and watch HD video....
and connect the 5.1/7.1 sound thru the optical or the coaxial link directly to your AVR 3805.
You will not loose anything on the Blu-Ray.
The sound is best processsed by the AVR3805, while the video, which is the real upgrade (BluRay) in terms of resolution of picture would be processed by your plasma.

Connect and Enjoy
