Why do I get somewhat differing results if I run the Auto-EQ function more times?

 

1) First, be sure to always adjust the settings in the Speaker Setup screen manually before proceeding to the Auto-EQ measurement. You can choose the Crossover Frequency for the front L/R, and LFE channels based on the manufacturer's specifications. If there is no manufacturer recommendation for the Crossover Slope setting, you might want to experiment with setting it to 24dB, as this often results in a more transparent L/R soundstage and tighter bass. 2) After the Speaker Setup parameters are properly entered, you can then run the Auto-EQ. There is no need to manually set the Speaker Distance and Gain, as those will be setup by the Auto-EQ process. 3) To begin the Auto-EQ process, first locate and set up the Microphone according to the instructions. Once everything is ready, run Auto-EQ. Remember to press 'Enter' and be sure to SAVE the settings from the first pass, which measures the speaker distances and the sensitivity. The second pass will perform the actual EQ measurement. You can then use the scroll arrow < and > to review the EQ settings for each speaker. Please note that the EQ only applies to the main 5.1 channels, as the rear L/R channels cannot be adjusted and are always set for a flat response. In addition, under most circumstance you should expect the adjustments that were made by the Auto-EQ process to be of relatively small increments/decrements. 4) The AVP-18 will purge the old EQ settings when repeating the Auto-EQ process. Nevertheless, to ensure consistent results we suggest that if there is a need to re-run the Auto-EQ process, to always 'Load Factory Default' before doing so. 5) After completing the Auto-EQ process, it is permissible to make manual adjustments in the Speaker Setup screen in order to change the Crossover Frequency and/or Slope of the crossover. There is no need to run Auto-EQ again.
