    Default How to test AVR, speaker, Joey setup when problem with surround

    werthliving.com

    Question on Hometheater 7.1

    I have dish Joey feeding Yamaha 673 feeding Panny 65VT60. The speaker configuration is -
    Pioneer SP-BS22 - two in front
    Pioneer SP-CS22 center
    Pioneer SP-BS21 - two in rear surround
    Pioneer SW-MK2 subwoofer
    Polk Audi TL1 --rear -- I believe these are 8 Ohms

    I have had this configuration for a year. I always thought there was a problem with the surround sound. Recently when my friend came over he also confirmed that the back surrounds were not giving any sound mostly hum.

    My question is how do I isolate the problem between Dish signal to Yamaha AVR to Pioneer speakers?

    Since this setup is in a basement we just finished a year ago (meaning speaker wires), I dont know if it is AVR, wires or what?

    Can you suggest some things I could try out?

    I have downloaded lot of audo files for testing.

    Another question is does Joey give less of a sound signal than Hopper?

    Soundtracks you get via Dish will be 5.1-channel max and thus will not contain back-surround information, only front left/center/right and left/right surround. To make the Polk back surround speakers active on 5.1-channel soundtracks you must apply Dolby Pro Logic IIx processing to Dolby Digital soundtracks. Your receiver should have a setting that will do that.

    So you have a center speaker and you are getting sound from it? It wasn't listed. Anyhow, if the wiring were the problem you would not even get hum from the surround speakers, so that can be ruled out. And you are getting sound from all three front speakers? If so, first make sure the speaker configuration is set properly in the receiver's setup menu -- 7.1-channel configuration with all speakers set to Small. Then try going through the speaker setup routine again, just to make sure all channels are working and set to the same level. If you still get no sound from the surrounds, that would suggest a problem with the receiver that might require service. If you do get proper output from the surrounds, it's probably a configuration error in either the receiver or the Joey, with the latter more likely. In particular, make sure the Joey is set to deliver bitstream or Dolby Digital audio output rather than PCM. Also ensure that the receiver is set to apply Dolby Pro Logic IIx to all signals, including Dolby Digital.

    Finally, many television broadcasts are plain stereo or mono, even if the devices are indicating 5.1. The stations or networks just leave their encoders in 5.1 mode regardless of what sort of signal they're feeding in. So make sure you test with programs that actually have 5.1 soundtracks, such as modern movies (especially action films) or many sports broadcasts, which typically have fairly constant activity in the surround channels.

    thanks. I went through yamaha YPAO calibration etc earlier.
    I will have to do more testing with just bluray player to AVR to speakers. I have no problem getting sound from 3.1 speakers.

    Other option is to switch Hopper and Joey locations and see if there is a difference in what sound hopper gives versus Jeoy gives.

    Is the Joey's audio output set to bitstream? If you get proper output with a Blu-ray player, that would narrow it down to a problem with the Joey.
