Re: Optical Port 2

I have the same problem - the only thing i have found so far is that I have to go into the setup on the amp and change the input for dvd from optical 1 to optical 2 and back again to switch between 2 devices

Ok so the issue is that after i have ran a hdmi cable from reciever to monitor, and 2 hdmi inputs (dvd and video2) into the reciever where im running a ps3 into the video2 port and foxtel/satellite tuner...

Try this, although recivers have video pass through, it is not the best option for video to your monitor. Depending on what you have for input/output on your TV/monitor, and, if you can, you should run all your video components directly to TV via(best)HDMI(video and sound) or, component and digital optical(best) or RCA, Then run digital optical out from you TV out to receiver in. You can use your monitors menu to chosse what you view and only have the onr input to you reciever. ASll you have to do then is go through you recievers menu to get the audio. Less connections less hassle. In other words, you would run your sat tuner to tv inputsat or cable, then dvd to dvd, PS3 to video 1 etc., on TV/monitor, then the single audio output to reciever.

No audio produce in optical connection

Typically when you use the optical connector from a DVD player there are several steps to getting everything ready to hear sound.

First: The Marantz Receiver will have a setup menu option for changing the DVD player to "optical" or it will say "digital" input. Once this is done, you should immediately get Sound.
Secondly, the DVD player (may) have an option to be switched to a digital output through the optical port. You would be able to find this out with it's user manual.
I really hope this helps,
Best Regards,

Input signals Marantz SR4003

There are four digital connectors on the back of the unit: 2 optical and 2 coaxial. They are marked a s 1 2 3 4. 1 and 2 are optical, 3 and 4 - coaxial. Also you have front optical connector marked as F.
You can connect 5 digital sources to your receiver. For example, connect your DVD to input 2 (optical) by optical cable and connect your DSS to input 3 by coaxial cable. Assign DVD to digital 2 and DSS to digital 3 in input setup menu.

Which optical inputs should I use for (1) audio output from hi-def cable box (connected to HDTV with component cables) and (2) audio output from DVD (connected to 3805 with component cables?

Hi, the Optical and Coaxial inputs are assignable to whichever input you need them on. Plug the Optical cables from your DVD and HD cable box into any of the OPTICAL INPUTS (1 and 2 is fine, but write down your connections on paper)

You will then need to go into the setup of the AVR on the screen and assign the OPTICAL connections to the correct inputs (Probably TV/CAB and DVD.

Use the SYSTEM SETUP button on the factory remote, and you should see the on-screen menu appear on your TV. Go to INPUT ASSIGNMENT and choose the input for the DVD and assign OPTICAL 1 or 2...

Sony DG510 - Not Getting surround sound out of Cable

Did you try it on BOTH the SAT and Video 2 optical ports? Still not working? Could be the Optical cable is bad.

Does your Cable Box also have a coaxial digital ouput? It looks just like a standard RCA connector but says Digital somewhere near it. Try one conductor of a standard audio cable from it to the "DVD" coax connector. Select DVD to hear it.

If it still doesn't work jump into the Cable Box setup to make sure it's output is set up properly.

I would recommend using the coaxial digital option if you have it.
1) The cable isn't special or expensive like the optical cable is; a garden-variety RCA cable works just fine.
2) You have virtually unlimited distance to work with in the house.
3) You don't have to be so darned careful with it as with optical.

Optical port doors on my av reciever ( sony ) broke off and now the optical cable does not have a tight fit

Hi vbuell!

On most AV equipment, the door on the optical port is there more to keep dust and debris out of the port than anything else. I suppose it could put a small amount of pressure on the cable end as well, but I don't think it should be significant.

If your sound quality has not deteriorated, then the optical cable is still working OK and I wouldn't worry about the situation too much. There are many ways that you could tighten up the fit, but most risk getting debris into the fitting, which is obviously not a good thing.

If your sound quality has deteriorated, I would first get a can of compressed air (you can get one at any store that sells computer parts for a few dollars) and blow out the "hole" where the optical cable plugs in. Plug in the cable again and see if your sound quality has returned. If so, you are good to go. If not, I'd make sure that your cable is working (if it's plugged it at the other end, the end that goes into the receiver should be lit up). If still no sound, you may need to take the unit to an authorized Sony repair facility, which you can find at

Good luck, and I hope your problem is resolved. If you feel it is appropriate, I would appreciate a rating on my advice that I've given.

Optical inputs

In short yes!

If you have two optical inputs and two equipment (PS3 and HDVD) then you shouldnt have a problem at all. Just make sure you change the mode of the receiver to TV/SAT when you want to use the HDDVD. Your problem may be the video out put.

If i was you i would do the following:

1. Get rid of all your optical cables as you won't need it.
2. If your receiver support HDMI then by default HDMI will send both video and digital sound.
3. Plug the HDMI of the PS3 to the HDMI input of the receiver, plug the HDMI of the HDDVD player into the HDMI 2 of the receiver and plug 1 HDMI cable from the receiver to the tv/monitor you have.

That is the best set up so when you play PS3 you select dvd/ld and when you watch hddvd you select tv/sat.

However having said all that the fact that you have dvd/ld suggests you actually don't have HDMI at all on the receiver(...i just checked the specs of the receiver). Which means you will need to have 2 hdmi inputs for your tv and you will need to have the 2 optical connections.

But in short yes to your question.

hope this is not too confusing.

good luck

HDMI sound?

I had the same problem with my PS3. I have a HD cable box with HDMI out, a Sony DVD player with HDMI out. The Sony receiver STR-DG800 only has the HDMI inputs (sat/tv and dvd) and the HDMI is only a pass through port and will not decode audio.
I purchase a HDMI 4 port switch from Newegg (HS-41A0 to hook up the DVD and PS3 to the DVD HDMI and switch between the DVD player and the PS3. It took me several days to figure out how to make this work with the settings on the reciver.

1 the DVD player must use the coaxial in jack for sound on the receiver.
2. the PS3 must use the optical connection on video1
3. the sound settings in the PS3 must be set to PCM
4. set the sound setting on the receiver to the following

a. on the remote press AMP button then the MENU button, next press the down arrow to you see 5- AUDIO SET - then press enter.
b.set sound decode priorty to PCM
c. next scroll down to you see digital assign - press enter
assign VID1 OPTICAL to DVD ( this allows the pcm output from the PS3 to play through the receiver), next assign DVD to COAXIAL setting DVD to DVD (this allows the digital sound to play from your DVD player).

So when you use your remote and select DVD, you can use your PS3 or DVD through the 1 DVD HDMI port.

No Audio

What port do you have the HDMI from you BD player into on the 510. If you have it on the DVD port then fiber optic will do you no good, the DVD HDMI only supports digital coax, the Video2 HDMI only accepts fiber optic, and there is an extra fiber optic for the Sat input. If your BD player does not have digital coax out, or if you dont want to buy another cable, just move the HDMI from DVD to Video2 on the 510. I am willing to bet you have the BD player plugged into the DVD HDMI port and the fiber optic cable from you BD player to the Video2 fiber input.
