Using Rear-Surrounds for stereo (2 channel) music (Pioneer VSX 21) - 4 speakers total

post #1 of 4
Thread Starter 

I hope the forum can help me out with the following “dilemma”. I just upgraded (if you want to call it that) my Yamaha CR620 receiver and Realistic Speakers. It still works (Other than a bad Phono Input) as good as the day I bought it, but I hear electronics have made some headway in the last 35 years…. So into the hobby room it went.

 

I purchased the Pioneer VSX 21-THX receiver and a pair of JBL ES80’s. I have the JBL’s bi-amped. Needless to say, it sounds great. I broke out all my once played vinyl (I was the type of guy who played his albums once just to tape them). Pink Floyd dark side of the moon…..wow. Very nice sound. What’s not to like over the CR620.

 

Sorry for digressing. My question is. I plan on using it only for music (tape, albums, CD’s, radio) for the near future. Home theater may be in the works, but not yet.  Would using the surround amps on the receiver for 2 additional speakers, first of all work, and would they do anything to the “Quality” of the music?

 

The manual says the Pro-Logic setting offers up to 7.1 channel sound from 2 channel sources. I was tempted to hook up the old radio shack speakers, but I don’t know what impedance they are etc, and don’t want to do any harm. I’d like to error on the safe side.

 

Would the pro logic setting (Or another setting …..There are about 11 additional settings (THX, Neo6 music, etc)) power the surround channel/amp from “music” sources. And if they did, would you feel this would offer anything to my music only sources.

 

I was looking at the JBL L830’s for the “rear” speakers.

 

 I don’t want to turn this into an expensive Quadraphonic system, but if anyone has had good results with this type of hookup (Again, for mainly MUSIC listening), I’d like to hear about it.  

 

I appreciate any help from the group.  Thanks

Hi Gary, welcome to the forum!

To answer your first question - if your receiver has an "All Channel Stereo" mode, that would be the mode that would best expand the 2 channel stereo signal to all connected speakers.  Exactly how the stereo signal is split and routed to each channel likely varies from receiver manufacturer to receiver manufacturer - but All Channel Stereo is the most likely to pump a virtually identical L/R signal through each speaker on the respective 'side".  Most of the DSP (Digital Signal Processing) modes like Arena, Studio, etc. add varying degrees of delay and reverberation to the signal, and IMO isn't really a worthwhile feature at all.  The remaining modes, like Neo6, Dolby ProLogic II, etc. are designed to create a surround sound field that emphasizes front speakers moreso than the surrounds - so those modes will not provide the "uniform" soundfield that I believe you're looking for by adding additional speakers.

As far as what it "adds" to the music, I am a firm believer that good 2 channel material is best listened to in a straightforward 2-channel setup.  Simply adding speakers to a system only succeeds in adding a bit of volume, and often at the expense of muddying the sound and destroying any sense of proper imaging.  These problems will be ever further exacerbated if the speakers are not all identical, as the tonal qualities vary widely across speaker brands and even different models from the same manufacturer.

It probably would be better to use the side-surround channels to drive your second pair of speakers instead of the rear-surround channels. To the extent that your two-channel sources have any matrixed surround-sound information included, the side-surround channels are where that audio normally would be sent.

If you haven't already done so, don't forget to run the MCACC room equalization. it should significantly improve the sounds you hear, no matter how many channels you listen to.

Thanks for the Input Jason, Selden.  I think I'll enjoy what I have now. Most likely I'll invest in a powered sub, rather than additional speakers...until if/when I get into the home theater stuff anyway.

Thanks again.
