Trouble with new Setup

post #1 of 7
Thread Starter 
Alright, I am not exactly sure what would be the cause of this issue so I figured I would post here for ideas or suggestions. I have an Onkyo TX-SR508 Amp, and originally was using some standard Energy Take Classic 5.1 Speakers. I saw some some Polk Audio speakers for cheap, so I picked up a pair, Monitor 60 CS2. I also purchased an equivalent Center Channel.

Now here comes the problem. The sound isn't being reproduced properly. For example, if I am flipping through the channels, the first few seconds I might only hear sound out of the front left and right speaker and then it will readjust and send the vocal to the center channel and use the front left and right speakers properly. There are times during commercial breaks, where the audio does the same thing switching between commercials, where the center channel is quiet at first, then a few seconds and the vocal is moved from the left and right speakers to the center channel like it is suppose to.

Another example would be if I am watching lets say, Football, where the audio comes from both the announcers and also from the field and such, that sometimes when it switches to the referees talking it takes a few seconds for the vocal audio to be sent to the center channel.

So here is what I am thinking it may be.... I know the receiver only handles 20W per channel, and the speakers are rated higher, i just assumed that meant they would not be able to be as loud as they could.... but maybe its causing it to delay sending the signal.

Or that possibly the auto detect setup was done incorrectly. I was pretty sure I ran it a second time just to make sure, but maybe not.

The last thing I was thinking was maybe there is a setting on the receiver to detect audio volumes and to adjust the speakers accordingly, and that it is not initializing properly.

A side note, I can't remember a time during a movie where it has sounded odd, but it has during TV shows for sure.

The reason there is a delay is because the sound you are receiving is only two-channel sound, and the receiver is apparently taking a few seconds to decide to synthesize sound for the center speaker.

You would possibly be better off if you could set the receiver to just use two channels only for TV viewing.

The speaker rating is irrelevant to this issue.

That is certainly logical, however I never had this issue before with the setup, which I also had as 5.1. I didn't add any speakers, just swapped some out.

Well, I can't think of any way a speaker change could possibly have anything to do with it.

I don't know what device you are talking about as the Onkyo TX-SR508 is an AVR, not an amp:

I'll presume that your post is in error as far as the type of device.

While TV sound is always transmitted using Dolby Digital, sources that are mono, stereo, or 5.1 is accommodated. The actual nature of the sound that is being transmitted at any instant is indicated by metadata that is transmitted as part of the digital sound data stream.

it is the responsibility of the receiver to route the various channel configurations that are transmitted into something that is suitable for the speakers at the receiving end.

So, the changes that you are hearing can be caused by the channel(s) that you are watching being mapped into your speaker configuration by the receiver.

The AVR is just the messenger. Don't shoot the messenger!

You are right, it is an AVR, I am not so technical with the terminology.

I guess my confusion is, I have changed nothing other than switch out the speakers and yet, the sound is not being sent the speakers properly, or with some delay. A delay that had not been previously noticeable. It is odd watching a show, hearing the voice track coming out of the left and right speaker than hearing it phase to the center channel instead, its odd because you can noticeably tell the center channel is not being used and then all of a sudden it is, and the direction of the sound has just changed. It is something I am getting use to at this point, none the less its still a bit annoying and something I am sure can be corrected. At this point, I will just redo the setup and hope that I had done something incorrectly.

Why not do a microprocessor reset on the Onkyo? You may look up the procedures in the Manual. smile.gif
