How to hook up

Hi, I can help. First of all it's not as hard as it looks. the last thing you will do is plug it in by the way ( this prevents any popping noises while hooking it up. We'll start with speakers, standard table lamp wire will do fine ( sometimes called zip cord) it is also usually polarized for you ( one of the two sides of the wire will be a little ribbed and the other will be smooth ) this makes it a little easier to keep speaker polarity correct( i usually go with the ribbed wire as hot) always make sure the positive(+) on the receivers speaker terminals are connected to the same on the speaker( the stereo and speakers will almost for sure be marked with red and black to help with that-red being + and black -) Next hook up something to the antenna terminal on the stereo for radio reception-the terminals will be marked 75ohm and 300ohm, if you do not have an antenna for this or don't listen to much radio not to worry, I find just a simple little wire bread tie with some of the plastic end stripped off works nicely for most local stations ( you will know when any antenna you try is connected by the fact you will stop getting just static.) Next connect whatever you want to listen to through your stereo, example: a dvd player can be connected with the dvd players " AUDIO OUT " going into the receivers connection for dvd (these are called rca connections-and are typically red and white plugs at both ends) also if listening in surround mode you can hook up a single rca cable to the orange connector on back of dvd player ( marked maybe as " DIGITAL PCM/LPCM " or simply " COAXIAL"the other end goes into the same connector on back of receiver. If no orange jack you may have a squarish looking connection called simply " DIGITAL IN " there may be a few of these, ones for satellite,cable,t.v. etc. These are called a "TOSLINK" connector, they are a rather stiff fiber optic cable with squarish ends that plug into the source with the surround sound output ( example when dvd player is playing the toslink jack will be lit up a little with a reddish light) same with a tv's digital output as well as cable/sat box's digital out. so that about wraps it up-just connect what you want to listen to with either rca cables or the toslink connectors-output of device being played to input on back of stereo. And if you need to connect up a recorder of any kind hook up recorders "LINE INPUT" to receivers " REC OUT" rca jacks. Thanks for choosing FixYa, I hope this helps,write back to let us know how we did or if we can be of more assistance. Good luck, Prodzilla

Hello I am trying to hook up a dvd player to my kenwood vr 505 that has been in storage for a while. How do you hook up a HD tv and dvd. Does it go out from the receiver to the tv, and does the dvd go...

If you are using HDMI cables for HD then you will need to connect this from your dvd player to you tv. Then connect your dvd player to you amp using either fiberoptic cable or co-axil (orange) this will transfer your dolby digital signal. Then connect other stuff like video / freeview etc to the yellow red and white on amp, you may need a scart to phono cable. Then connect monitor out from you amp to the yellow on your tv .This way when you select the source on the amp the picture will change also. If you search the web for vr-505 manual there are some sites offering it.

No digital audo from dvdld in

That's probably just for the video.  Plug in the L & R RCA plugs for the sound or just use an HDMI cable between your receiver and DVD player.  HDMI cables handle everything in one convenient cable.

Hookup diagram for Yamaha avr-863 receiver

It's the other way around.

Hook up the Cable box to the Amp; and the blu-ray to the amp, then connect amp to LCD.

you want to use the best available options for audio:
HDMI > Digital Optical > Digital Coax > standard RCA

And the similar for video:
HDMI > Component > SVideo > RCA cables

I would connect Blu-Ray via HDMI to Amp, and Cable box via HDMI to Amp. If your cable box does NOT support HDMI, but you have an HD package, ask your cable company for an upgraded box.

No Dolby Digital through DVD player

Have you configured the digital output settings on the DVD player? You may need to set the digital output format in the DVD player setup menu. If it is set for LPCM then you won't get sound. It has to be set for bitstream and yoou may need to tell the player what output to use.

As you didn't mention the brand of DVD player, I can't really give you any detailed instructions.

Also try using the optical cable that you have connected to the cable box to test it and see if you get any output on that connector. If yyou do then it is a setting in the amp that is not configured properly,

Best of luck

NO AUDIO/set up problems

For this Sony, you have to use separate audio cable(s). Either optical in BD or Digital Audio in DVD (single coaxial cable will do the trick) I bet the display says UNLOCK. I had the same problem, very dumb.

Good day!

Need unlock code for sony str-dg520 5.1

The HDMI inputs are pass through inputs only. The reciever cannot recieve any sound signals through the HDMI's. The reciever acts as a selector switch for the HDMI inputs only. Whatever input you have selected on the reciever is the one that is being sent through the output to your TV. The "unlock" display shows when there is no sound signal sent to the reciever. There is no code to unlock. This is the reciever's way of telling you that there is no sound being sent to it from that input. Since there is no sound being processed from the HDMI's, you need to hook up an additional audio cable from the device to the reciever (preferrably an optical cable). When the reciever recieves an audio signal, it will then "unlock". I know it is confusing. I had to look into this problem myself, so I'm happy to help. Higher end recievers will actually recieve and process sound signals from the HDMI's. When I bought this one I thought it was going to do the same. That's what I got for trying to save a couple bucks on the cheeper model! Although it is still a good reciever.

Hooking up DVD player to proscan TV. Video is coming thru but there is no sound.A digital cable box from comcast is in the mix. I can usually figure things out but I am stumped on this one. Any ideas?

Hi,if you have video and no sound you have hooked up the dvd with component cables but you still need phono cables for sound,run these from the dvd audio output to tv audio in,if you have a amp for sound come from dvd out to dvd in on your amp.

hope this helps.
