Can i use REW on Yamaha RX-A1050 & How ?

[KAKA]

Hi,

First of all thanks for helping me in choosing the receiver. As per my earlier post i got Yamaha RX-A1050 which i am enjoying a lot. particularly network features and speed of ios/android app way better than denon/marantz offering. i m enjoying the sound of the receiver particularly when i select YPAO Natural. But was reading and wanted to get my hands little dirty by trying Room Equalization Wizard approach of calibrating. But all i know at this stage is how to manually adjust PEQ on Yamaha but no idea on how/can REW can be used to calibrate. I know it would be lengthy discussion but appreciate if you can help me. i am really a beginner in this regard and need good guidance on going thru.

I have a rectangular room so right now i will get some sound absorbers and fix accordingly to suppress some echoes but if digital room correction can add to physical acoustic treatment it would be wonderful.

You can't use REW to calibrate anything. REW can only be used with another external product. REW only makes the correction curves, it has to way to apply to to the input or output signals.

If you aren't using external amplification on anything, then the cheapest option is to use miniDSP's HDMI correction unit (nanAVR is memory serves) which is around $250. Then you still need a microphone and mic stand.

My advice is if you are serious, buy a Umik mic from miniDSP and start measuring your speakers and start reading and figuring out proper speaker measuring protocol. This will be a good indicator as to whether or not you really want to spend the time and money to really dig into this stuff.

Thanks fuzz. i didn't know that and i think i don;t want to go the route of buying mic and testing but can you tell which way i can use manual PEQ if i want to do it on my receiver. i mean any baseline of which frequency to tweak based on room acoustics..

Let say YPAO has set +4db for 62hz and similarly for other frequencies if i need to tweak it other than just adjusting on my own with out any reference. is there any reference or something which i can then use to either reduce or increase db based on room acoustics. I know YPAO sets it based on test tones it emits during calibration but just trying to behave like a pro if i can . i m just trying to learn more on room acoustics and digital room equalization

Without knowing what the response curve looks like, you're just adjusting blind. Those with a trained ear and a lot of experience can dead reckon it and actually get a pretty smooth response, but if you don't have that experience, then the best you can do is adjust it so it sounds best to you.

One easy and practical way is to get a live recording of a singer or band that you've heard live. Adjust until it sounds natural and like you remember it (although remember that acoustic memory is extremely short).

There is also a CD sold by Siegfried Linkwitz that is a test CD. He uses a lot of familiar and natural sounds to allow you to see if your speakers sound as they should. One track he rips a piece of paper in half. Not only is this a sound familiar to most people, but it's one you can mimic next to the recording. A good way to see how natural sounding your system is.
