More speakers and its quieter?

[pelvis70]

I have a denon avr-3802 and I was running two towers a center and two rears (paradigm) bookshelf. I just added two side speakers ( paradigm Bookshelf) and it seems now I have to run my volume higher in order to get the same volume levels as before? Movie i used to run at -28 I now need to run at -18 for same sound, I thought because of the amp having 7 seperate amps one for each channel that it should be louder? can someone please explain? also if it is going to be a little less powerful if I add an amplifier will it improve all speakers or just fronts? thanks

receivers don't have separate amps for each channel, they all share the amp. so its normal.

adding a separate amp will "improve" the speaker's performance but I doubt you need them ... -28, -18 doesn't matter as long as it sounds good to you, those are just number representations.

Not to bash you Mike, but this is inaccurate. Receivers dohave separate amplifiers for each channel, but the all share the same power supply.

Now, as far as the problem goes, I'm not sure what would cause this to happen. Perhaps with the addition of 2 more speakers your receiver it reset its calibration. Double check that your channel trims are where they were before, that all of your connections are the same, etc. Some settings might've gotten changed (who knows why) that could affect the volume level.

jaxvon, right. exactly what I meant.

but it really is normal for the volume to go down in multichannel vs. stereo.

thanks for the help guys, I guess it doesnt matter, i just though maybe the amp would be working alot harder or something

The amps may work harder in some cases, yes

But, is that receiver designed for 7 speakers? Did you level match your setup properly? If not designed for 7 speakers, how did you wire the last two?
