Don't want to dump Mike's thread.

Plugged Audyssey in to MIC and hit sweep (didn't change anything in REW for it) clipping detected message, headroom red 0.0dB

Changed preferences, deleted mic cal file, leave C weighted checked?

(BTW, on the RS meter do I leave it on slow or fast?)

Now it wants me to calibrate, obviousely cant calibrate the Audyssey

clipping detected message

I finally took the Audyssey mic off the rigg today, yesterday I thought would be the last time I used it since the thread died but I forgot to do "spectral" though I think I need to try that other spectral program first. The above sweeps were with the mic laying on the bed, I just mounted it and for all the sweeps thus far i had the PC volume way down...oops

I thought the low stuff would be affected by not being mounted....bouncing around...but it was up high. And this was at a very low volume.

Uncheck C weighting for the audyssey mic. You can also calibrate it, run the calibration and use the reading off the radio shack meter for the SPL level.

also, when capturing the graphs, check include legend, and label your plots. It makes it easier for people reading the thread. Also, if clipping, lower the input level.

OK, set the RS to 120, when it said -6dB clicked save for 114dB, ran check levels, no good, red -10.7 Level is High

you don't need to calibrate so loud. The audyssey mic may not be able to measure that loud either.

Shoot for 100db and take some readings. Keep the input level low.

as in mic setting? it was at 17 with +20dB. Drop to +0dB and leave at 17 and drop the RS to 100dB master volume to -30dB and see if it registers on RS?

I'm sorry!

ok, boost off, calibration at -25dB did +2dB on RS set to 100dB, so entered 102dB

sweep at -25dB

thank you again! plot looks more realistic to me too, but I am still completely novice.

this is with the subs nice and warmed up as we swept and re-swept with the doors open to find the limit, then again doors closed all sealed up. I hear suspension issues at -12dB so this is 5Hz increments starting at -42dB and ending at -12dB

You have NO idea how much of a pain the SR door blocks were, how nice it was to take them out, but reset them up today for this

Hi,
what do i need to do in order to use the audyssey mic (ACM1HB) that came with my onkyo receiver?

i ran calibration and REW5 says too much variation. I connected a single cable with stereo jacks on both ends, from line-in of the soundcard (on-board), to a speaker input.





Can the mic be used? if not, which mic should i get?

Thanks!

So the ACM1HB Audyssey mic cannot be used, I have to buy one of the recommended mics for REW?

EDIT: Alrighty, took the plunge and purchased the miniDSP UMIK-1, going to set it up with HDMI output per the guides.

Thanks for your help!
