I plan on REW using an M-audio mobile pre with the ECM 8000 mic but I am not getting anywhere. I think I've connected it all correctly. I can play sound from i- tunes through the M-audio sound card and can hear sound through my speakers but i cannot get any sound from my mic (or another mic for that matter) I assume that i should be able to hear my voice through the speakers as well but this is not happening. Does any body know what could be wrong?

PS tried both windows XP and vista 32 sp1 thanks guys

Hi Bruce. I tried to do this using the loopback connection but the bar indicators showing input levels remained at -73 DB

Hi KJg. Thanks for outlining your experiences with M-Audio Mobile etc. Sounds like you got your rig working ok finally. I have same set up as you and same problems also. I've gotten as far as completing the sound card cal file. I think I fluked that actually. but The next step is causing me grief, the checking levels process. I cannot seem to get any input readings when I start the pink noise test. I am using the main speakers to set levels. I'm using the same type of connections as when I did the sound card cal file. I am using the same (right) channel but now input is from ECM8000 instead of sound card. I can get output figures but no input. my souncards controls are at max (input and output) REW cannot find any input controls for me to use to boost input either. Any ideas? please

 

[Jason Schultz]

yes I did. no insult taken. I expect the problem will be somthing simple like that( i hope so). Maybe Brucek will chime in again?
Connection wise I am using a TRS/RCA plug from the left output of my soundcard, going into AVR. Mic is going into right channel of Y adaptor into stereo 3.5mm input.
I can hear pink noise at 75 dB from speakers but mic is picking up zilch.

Correction those plugs are TS plugs and not TRS

OK I've worked out the problem !

If you are using the ECM8000 with M-Audio mobile pre:
When measuring speakers (not soundcard measurement) you must plug the mic into the XLR mic inputs on the rear because it has a gain control which you need. Channel 2 on rear corresponds to the Right channel on REW input. I've now got my measurement levels sorted!

I still had it set up as in the sound card measurement set up where it states you must use line level inputs. nowhere does it say to reverse this. anyay i'm happy now things are moving along nicely
