Question about Sony STR-K750P A/V Receiver

1 Answer

Moved into a new home with surround sound connected to main tv and also speakers throughout house with individual column controls on wall of each room. Previously had cable installed before I moved in

Moved into a new home with surround sound connected to main tv and also speakers throughout house with individual column controls on wall of each room. Previously had cable installed before I moved in, I had direct tv installed. The surround sounds works great but when I switch the receiver to music, I still get music through the surround sound, but no matter which speaker button I push, I cannot get any sound from any of the room speakers, none of the cables connected from the receiver to the panel for the room speakers were disturbed. I am fairly talented at connecting electronics but am at a loss on this. Is there some type of fuse in this circuit? Is there a way for me to connect another sound source to each speaker connector to test to make sure that they are working or does it need to come through the receiver to have enough power to operate the speakers. Thanks so much for any help

SOURCE: No sound from rear speakers during test tone usng Sony STR-DE475

I had this problem last night.

To solve it, you can reset the amp by:

1) Put the receiver on stand-by
2) Hold down "MODE" button and press on button
3) "S.F. CLR" appears in the display and surround is back on.


Good luck

SOURCE: connecting pc audio to str-de898

You're close. PHONO is NEVER the place to send Line Level signals. It is for the small output produced by a phono cartridge only. Google RIAA equalization to see why it sounds so bad when connected that way.

That you get sound through Phono at least proves your PC is producing an output. Now we have to figure out why your RECEIVER doesn't sense the program where it should be connected.

If you have another analog audio source that works on the receiver, temporarily connect the PC audio there to see how it sounds. Then think about why it doesn't work in MD/TAPE, SA-CD/CD, TV/SAT, DVD, or either Video IN. Any of those should work.

SOURCE: I cannot get sound from a sony BDS350 (Blue ray

This must be configuration problem on the BD player. In this case receiver just outputs the signal it receives digitally. If it displayes PCM 2ch, that means it receives only 2 channel audio from BD player.
You can try to configure the BD player not to decode audio and to output the RAW stream over coax cable to the receiver. Then the receiver should get raw Dolby Digital encoded data and be able to decode it into 5.1 channels. It should also display Dolby D instead of PCM in such case.

SOURCE: Hi, having a problem with

RCA cable. It's called RCA when carrying Line Level audio; Coaxial when carrying digital data.

Does the sub work when you run speaker setup? It's in the manual.

Connection between harmon receiver and A-bus in wall speakers...


There is a CAT5/RJ45 A-Bus interface on the back of the HK AVR 435. That needs to connect to your A-BUS "hub". HK has two hub products: ABH-4000 and ABH-4 (older). Then CAT5 cable can be run from this hub to Wall-installed room-specific controls. HK has the AB-2 product, but any ABus compatible wall control will work. From the wall control, you wire regular audio cable to the speakers. So, some of the questions/issues to solve are: where do the existing wires go that are connected to the in-wall speakers? Typically that location is where to place your in-wall volume and source controls. Then the CAT5 gets wired from those controls back to the hub. And all that's required is a single CAT5 from the AVR to the Hub.

Sharp LC-37D6U Aquos audio problem


Your Aquos does not have a separate Audio board, audio circuits are mainly on main pcb. If the guy was able to fix the problem by hooking a surround to the audio out, that means that is a problem with speakers contacts or with one of the outputs.
Borrow a surround or use an amplified speakers set and check if you can fix it with this trick.
To do a real fix, a technician must open the tv, and test all audio connection, and onboard connection to audio outputs to see what is wrong.
If TV is going to work with a surround you will probably get a far better audio quality than the one you get now from TV speakers.

Surround sound hookup question?


It looks like all you'll need to do is hook up audio out from DirecTV to audio in on the surround sound system. Sony has an interesting hookup recommendation guide on the product support site:

http://esupport.sony.com/US/perl/model-home.pl?mdl=DAVC700&LOC=3

That should give you the connection options. The short answer, though, is to connect the best audio out from DirecTV to an audio in on the surround sound and then choose that option in the surround sound system when you want to watch TV.
