5.1 graphing

[aceinc]

I have a simple question.

What is the easiest way to do a graph of a 5.1 system using REW?

Hopefully there is a simple answer.

REW outputs a mono signal, so certainly there will be no decoding or steering allowed.

If you want to do a response of each speaker you could simply hook each one up individually to the front left (as an example) and feed the left channel of the receiver while in stereo mode.

What about an all channel stereo mode which some receivers like Onkyo's have. Would that work?

[brucek]

Would that work?

I really don't think so. As soon as you have a DSP involved that uses phasing for the steering, a mono signal makes it unhappy.

Getting creative with RCA "y" cables won't help?

OK, then what is the best way to create a single graphic display of all of the individual channels? Basically one chart with 6 or 8 traces labeled for each channel.

Do what I suggested in my first post and put all the plots on the All Measured screen....

IMO, you could also do Full Mono (Onkyo's have this) and disconnect all but one speaker at a time.

Doing this would allow you to keep your speakers in the locations they are already in.

I support Brucek's recommendation to use the All-Measured screen.

Most receivers have multichannel pre-ins on them too...so just hook up the output from REW to one input at a time.

Or, you can move the rear channel speaker cables to the main outputs. That way the sweep will show their response.
