I calibrated to 75 db using my Radio Shack meter prior to running ARC. Should I have set up anything else separately audio-wise?
Before doing ARC Measurements, set the Setup / Speaker Calibration / Noise Level value, and adjust the volume knob on your subwoofer. It sounds like you did that.
NOTE: To set Noise Level correctly you need to set the Left Front speaker's volume trim value to 0dB first. This is apparently a bug. You should also have the subwoofer volume trim at 0dB when adjusting its internal volume knob.
Before or after setting up ARC, be sure to enter correct values for your Setup / Listener Position (speaker distances) and for the Phase and Polarity of your subwoofer in both the Movie and Music configuration. ARC only listens to one speaker at a time so it is OK to adjust these settings after setting up ARC without having to do new measurements.
[EXCEPTION: If you have more than one subwoofer, you need to set up correct Polarity and Phase for all of them *BEFORE* doing ARC Measurements since ARC listens to your entire set of subwoofers at the same time.]
Room Resonance Filter, Center EQ, THX Ultra 2, and Boundary Gain Compensation settings will be ignored during ARC Measurements and for any source with Room EQ = ON during playback after setting up ARC.
The ARC Measurements will also ignore the cross over settings and speaker levels you currently have set. Only the Noise Level is used, and of course the volume knob setting on your subwoofer. The ARC Upload will load new cross over settings and speaker levels.
Be sure that Setup / Source Setup / Room EQ = ON is set for all your sources after you Upload ARC settings for the first time.
Do not fiddle with the crossover and speaker level settings ARC Uploads into the Setup menu for you as you will mess up what ARC has set up.
After doing an ARC Upload, it is wise to do a Save User and/or Installer Settings to capture the crossover and speaker level settings changes ARC includes as part of the Upload. This makes sure you won't mess up those settings if you ever need to do a Reload from those memories.
If you have more than one subwoofer, you *STILL* should set your speaker configuration to "1 subwoofer" in the Setup menu when using ARC.
Read the new Section 3.15 in the Manual for other guidance on setting up and using ARC.
