Hello All,

This issue is fairly straight forward. I've explained this previously in another thread, but will repost it here for your convenience.

First, we strongly urge you to use the internal test tones on the 1070. They're easier to use and they are very accurate.

The above notwithstanding, there are many variables that could cause skewed results (including mode to mode variations)when using external calibration discs, such as the input type used (muti-channel analog vs. digital vs. analog stereo etc). Also, what surround mode you are in when performing the calibration can have a sizable effect. Using the internal test tones eliminates these variables.

On the 1070 you'll need to make sure you are not set to the multi-channel inputs when calibrating as the internal test tones will be affected by the rear panel bass management switch.

If something here is unclear, just give me a call. I'm here to help.

Best,

Scott
