    Hi there. I just replaced my receiver for my 5 speaker setup. (no sub) I bought a used Onkyo 605 that I tested at the sellers house and all seemed well. I brought it home, hooked up the 5 speakers, cable box with optical out and only have those terminals hooked up on the amp.

    I went into the amp's setup menu following the instruction book and set the TV/CBL tab to "digital optical#1" and the sound came on, and the amp showed the Dolby Digital D symbol on the HD channel that was playing....the only issue is that sound is only coming out of my right front/rear speakers. No sound, no hiss, no buzzing at all from the center and left front/rear speakers. What could cause this? I checked that all the wires were going into proper +/- connections, and an hour ago they worked fine on the old amp so what could I have done wrong or not doing to make it work?

    (I have not tried to Audissey mic setup yet to see if I can hear the test tone in the speakers)
    But I really doubt I could have broken 3 terminals carrying it from my car seat, to my home when I saw it in action on the other guy's TV/speakers.
    Thanks for any help!

    mmmmmm.. moving old kit from one place to another. First get a battery and check your speakers, basic click test. If that seems ok then use a standard rca cable and do a channel test.. a finger on the middle pin should make a nice buzz.

    If that doesn't work on all channels you will have to open it up and check the speaker fuses.

    You don't need the Audyssey mic connected to try the test sounds. Try that, and see if all the speakers produce the sound of the test. Even though the speaker wires may look like they are right, make sure they are making a good connection. Try a slight tug on each one, to see if they are tight, at both ends. If all else fails, reset the receiver to factory settings (as it was brand new in the box). The manual will tell you how. When that's done, run the test again. If working correctly, you'll have to redo all the settings, like starting from scratch.
    Good luck!

    I put what I did because one of these came through my workshop about 4 months ago.. blown speaker fuses on right and rears. 4A slow blow t/l

    They seem to be a little picky about exotic (high capacitance) speaker cables as the output stages do seem liable to overshoot when faced with any unusually ringy/pushy loads. maybe that's why they have fuses instead of the modern standard over voltage/current sensors.. The silence.. complete silence.. says output stage fault or non connection to speakers to me.

    I agree tho.. going through the book and starting again with the setup seems like a very sensible move. Do you know if your optical source is working properly?.. and was it running like that when you saw it working before buying.

    I did the test sound, and all speakers make sounds, however they are not in the order of the hookups. (although it is possible I mixed some wires up to wrong locations)
    However, I have a 5.1 setup and i'm not using surr left/right channels, and when I do the test, it makes sounds for those on the wrong speakers, so I believe that the previous owners setup, or the amp somehow thinks I have speakers connected to surr left/right, even though there are no wires physically attached to those terminals. This is kind of baffling to me. I will try and do the factory reset so hopefully it won't even "see" those speakers when I am finished.
    I am getting test sounds on all speakers, even if they are in the wrong order, so I don't think anything is blown out. I'm not using anything hard core, just some entry level floor standing polk front speakers, and some small 6 ohm sony cube speakers in the back.
    Thanks for the advice people! :)

    Referring to the bold print in the quote:
    You say you're using sony cube speakers in the back, but just before saying that, you say there's no wires attached to those terminals!
    I think I see your problem. You don't know what speakers are what. It seems that you have a 7.1 receiver, but only using as 5.1 setup?

    The left surround and right surround ARE the rear speakers, in a 5.1 setup. You only use back left surround and back right surround, with a 7.1 setup. When you go from a 5.1 to a 7.1 setup, the rear speakers in the 5.1 become side speakers, and you add the two rear speakers, to make it 7.1 surround. Do not use the back left surround and back right surround connections, in a 5.1 setup. This now sounds like what you did. Being an Onkyo person myself, I should have realized this earlier (605 is a 7.1 receiver).

    JVC, I just didn't phrase my comment about the speakers in the back, I just meant they were in the back of the room, not back behind me. I have them properly placed in the rear left/right terminals, NOT the surr left/right, since the Onkyo guide says that for a 5.1 setup, to not use surround L/R.
    I figured out the issue and the previous owner had the optical 1 input jack Dolby settings set to mono something, or something not exactly compatible with 5.1 speaker setup, therefore, I was only getting sound in the front.
    I didn't know that with this receiver, you could assign not only each input source setting, but also the individual sound setting. (such as theater mode/movie/music/ and separate Dolby and DTS settings.

    Now if I could only figure out how to turn the bass down! When watching regular tv and something as "non-action" as 'House Hunters', there is booming bass that i'm sure isn't the most cordial thing to have the neighbors listen to. When I set the cable box input to process Dolby D, it sounds great but so bass boomy. If I switch it to something else or 'direct' the quality/volume seems to drop, but also the bass, which my wife is happy about, but i'm not happy about the quality dtop.

    When using a 5.1 setup with a 7.1 receiver, you use the surround left and surround right connections for your rear speakers! Plain and simple!
    You are misreading the guide. On page 20 of the manual, it says very clearly:

    • If you use 4 or 5 speakers, connect each of the two
    surround speakers to the SURR SPEAKERS terminals.
    Do not connect them to the SURR BACK
    SPEAKERS terminals.


    Your speaker connections are labelled: Front Left, Front Right, Surround Left, Surround Right, Center, Subwoofer, Surround Back Left, Surround Back Right. The Surround Back L/R speakers are the 6th & 7th speakers, of a 7.1 setup (farthest back, behind you). You do not use those in a 5.1 setup. I PROMISE!

    As far as bass, you said you don't have a sub. Try setting the crossover for the speakers, at different settings, and see which sounds best. You'll find those settings in the receiver's setup menus. If you're not using a sub, the speakers should normally be set to "Large", in the settings. If that's too much bass, try setting them to "Small". Without a sub, and speakers set to small, you may not get any bass at all. You really need a powered subwoofer! You may find a deal on a used one on Craig's List.
