Do I need to run REW on my HT if using Auto Calibration


Do I really need to use REW if my receiver has auto calibration? I have a Yamaha 663 receiver with the auto room calibration feature, and I have run this a couple times to set everything but I am not sure if I should go ahead and run REW or not. Would I really benefit from using it?

I have two sub woofers and a 7.1 system/speaker set up. Although the Auto Calibration told me to set the cross over freq to max, not sure if that meant all the way to 120 or down to 50. The sub-woofers I have are not exactly the same, one is a DCM bottom firing 10" and the other is a Polk 8" front firing.

Any suggestions?

I have the REW software on a MacBook, and I believe I have calibrated it correctly. And I also have a Radio Shack digital sound meter.

Definately run it.

Auto cal. in a receiver is not 100% by any means, REW wil point out where it missed.

Having 2 subs only increases the chance of there being a problem, might as well find out now.

I'd set XO at 50 before 120, but really, 80 might be best if its an option. Try both 50 then 80. your ears should be your guide in this.

Well I am game for running it, but assume I know nothing Now that I have my sound card calibrated such as it is. I do not have a BFD so I would assume by the setup instructions I am going to use just the right in and out's. Right in on the sound meter and right in for the receiver?

Re: Do I need to run REW on my HT if using Auto Calibration


I consider myself an intelligent person but I am having some difficulty figure out the specifics on what to measure for what type of connections. Most of the diagrams show connections to the BFD but none if you just have a receiver. And most seem to talk about measuring your subs/low freq. Are there any tutorials or step by step how to's. Sorry to be so ignorant.

Re: Do I need to run REW on my HT if using Auto Calibration


Me too, and I had issues last month when I ran it, look for my thread, you'll see as I posted my issues, the experienced members here answered them. If you notice my first post, I outlined my equipment and room size, you can start there.

BFD is optional, not required, I don't have one.

You MUST HOWEVER read the first post, the stickied thread of REW info.

Find the 'GUIDES' section, then read the first 3 bullets, skip the 4th as its about BFD. I used this diagram from the guides section, minus the BFD part of course;

I must be doing something wrong during my sound card calibration. I seem to get it calibrated but when I do step 7 here, my measurement does not base out at 0 but like at 75db its flat as a pancake but not at 0 I am not sure what I am doing wrong.

It seems that you're starting to have fun calibrating everything after the build ...

Is okay to have two subs, but is preferred to have two similar ... by the way: Did you do the crawling test or just placed them in the front wall???

When you get REW running ... calibrate one sub at a time, then combine their response to get the best out of the system

REW looks intimidating, but after a couple of measurements you'll see how easy is to use

Hopefully you won't need a BFD ... after you run REW try to adjust the response with your receiver EQ (I have the RXV 2700 and that's what I did) and I'm happy with the results
