HI all .. my first post, please be gentle.
Attempting the initial calibration steps in Audiofrog-UMI-1-Setup-Instructions-for-REW for the UMI-1 Kit I'm on step 11 when I noticed something odd with the Mixer's microphone level vs. the usb pnp sound device's microphone level adjustment. Steps to reproduce are as follows.
Attach loopback cable configuration for UMI-1 USB PnP Sound Device as stated in instructions (step 2) and insert usb device.
Right click sound icon in tray -> Playback Devices
a) Ensure settings as stated in instructions
Close Playback Devices
Click sound icon in tray -> Click Mixer
a) Speakers (80)
b) Set slider of Microphone to (0)
Run REW
a) Set Output & Input to use UMI-1 USB PnP Sound Device
b) Input control will show 0.800 (matching usb device's (80) setting)
c) Output control is unchecked (as REW apparently desires it to be after enabling the input control)
d) Select "user main speaker test signal ..."
e) Optionally set the pink noise setting you desire (doesn't affect anything)
f) Leave all other settings as-is
g) Click calibrate sound card
- Had to adjust mic rew level down to 0.168
- Levels flat at -12.0 .. -9.7 .. -9.7
- No fluctuation of IN/Ref IN at all
Results:
You'd think you'd be done (and maybe I am) but with the Mixer mic at zero and even a couple of clicks higher it remains stable. However as I increase the mic level in the Mixer window the IN/Ref IN starts to fluctuate up and down more and more as you increase the Mixer's mic level. If I stop at 18 the fluctuations remain between -14 dBFS to -2 dBFS (which is considered acceptable according to REW's guidance in its dialog box).
Which one should be used to make the cal file? The Mixer with mic level of zero and IN/Ref IN flat or with it at level 18 and IN/Ref IN fluctuating? Thoughts?
Thank you!
