Chris, welcome to HTF and thank you for taking the time to share your expertise. I just got my 3808 yesterday - I did my first calibration using only 6 points (it set my front and rears to large - and I manually adjusted them back to small); my question is should I use all 8 positions? Also, if I redo the calibration does it automatically replace the old information? I like how it sounds, although it seems like my center is a little low along with my sub (SVS 20-39 powered with a NHT SA3 subamp). I don't know the last time I looked at my subamp setting on the back, but I will when I get home from work. It is putting my sub distance at 23', when it is only 12', or less,away - but this could easily be caused by my amp setting, more to come when I get home.

Besides those two issues I am very pleased with the Audyssey, thanks for providing such a wonderful product to the consumer. Oh, one last question, how do I upgrade to the Pro version, and how much does it cost to do so? Thanks, heading home shortly to do some more experimenting.

Mike

Just checked my sub settings, they are: phase = 0, High pass = 100, low pass = 80

I'm going to re-run the Audyssey and see what I get.

Hi Mike,

The difference between 6 and 8 points is hard to predict without knowing the problems in your room. Personally, I would suggest doing all 8 as this is not something you would have to do on a regular basis. The new calibration will replace the old settings.

I am concerned with the sub settings you list--they can't be right. High pass=100 and Low pass=80 means you have no bass! Did you reverse HP and LP? This could also explain the strange sub distance. It's important to not have any filters on the subwoofer. If you can't defeat them (or if there is no LFE input to the sub), then set the High Pass to the lowest possible frequency (20 Hz or below if possible) and the Low Pass to the highest possible frequency. Then the bass management in the 3808 and MultEQ can do their job properly.

Enabling the Pro version requires a firmware upgrade from Denon. Installers set their own pricing for running a professional installation. Don't forget that by doing so you also get Dynamic EQ enabled that corrects the frequency response when listening to non-reference volumes.

Regards,
Chris

Chris,

Well I feel like an idiot. It's painfully obvious that I didn't understand the point of the crossover - I feel like a newb. I thought that the HP would tell the sub to take anything below 100 and the LP anything lower than 80, but just typing that makes me realize the idiocy of that statement.

I can't shut them off, the SA3 is intended for NHTs old subs that weren't powered and before the time of these fancy receivers. I will go mess with this now and see what I get. Thanks for the reply, man I feel like a idiot. LOL

Mike

---Ok lowest possible frequency I can do on the HP is 65, and I've got the LP as high as it can go with Phase remaining unchanged. Going to redo the calibration and see what I get.

Mike,

The SVS 20-39PC is a powered sub, right? So, what's the purpose of the NHT amp?? The sub also has a crossover bypass button that you should press to "on". I don't see high pass and low pass controls on it. Only a low-pass that is defeated when you use crossover bypass. I would definitely recommend not using the NHT amp and the high-level inputs of the sub.

Chris

My SVS is 5+ years old, it is a non-amped sub, which is why I have the NHT amp. It is a 20-39, just not powered. I just got done redoing my calibration and it defiantly sounds better; however it still set my sub at 17'. I'm watching The Rock and it sounds really, really good. I don't really want to invest in a new sub right now - I've got phase set to 0, but I can change it to 90, 180, and 270. Although I'm pretty sure I don't need/want to do that.

A new sub would eliminate a piece from my rack, and SVS is having a great sale on the PB12-Plus/2 or a 20-39 PC-Plus.

Thanks Chris,

Mike

Ahh, OK. It's not the powered one. The reason for the longer distance found is due to the filters that can't be bypassed. Filters add delay to the signal and so MultEQ is seeing that and compensating for it. I'm glad to hear that things are sounding good.

Best,
Chris

Chris,

Good doesn't even begin to describe how this receiver sounds properly calibrated; the difference is night and day. Thank you for taking the time to walk me through the sub HP and LP FUBAR on my part

.

Thanks for the explanation about the filters...I'm just peachy with the way things are now

Thanks again for an excellent product and service.

Mike

When using up Auto setup with my Denon AVR 3808 it tells me in the manual to defeat my volume and crossover. Does that mean the volume, crossover and phase should be set to the lowest possible settings? I have a Paradigm PS-1000.
