Multi-Sub Optimizer Reference Manual

Overview of Use

To use Multi-Sub Optimizer (MSO), you perform the following steps:

  1. Decide whether you want to optimize the subs and their integration with the main speakers, or just the subs by themselves.
  2. Determine how you will configure your AVR and DSP devices before making measurements. [Details: reference section]
  3. Measure the frequency response of your subs, and optionally your main speakers, at multiple listening positions using separate measurement software. [Details: reference section]
  4. Export a text file from your measurement software in FRD format for each measurement. [Details: reference section]
  5. Import the text files into MSO. [Instructions: tutorial] [Details: reference section]
  6. Define filter channels for your subs and mains. [Instructions: tutorial] [Details: reference section]
  7. Add filters, delays and gains to these channels as desired. [Instructions: tutorial] [Details: reference section]
  8. Examine and alter gain, delay, and filter parameter values manually at any time as desired. [Details: reference section]
  9. Associate measurements with the filter channels you've defined. [Instructions: tutorial] [Details: reference section]
  10. Assign measurements to measurement groups (listening positions). [Instructions: tutorial] [Details: reference section]
  11. Make a graph of your measurement groups (listening positions). [Instructions: tutorial] [Details: reference section]
  12. Specify optimization options. [Instructions: tutorial] [Details: reference section]
  13. Run automatic optimization. [Details: reference section]
  14. List all filter parameters in a filter report. [Details: reference section]
  15. Enter the calculated filter parameters into your DSP device.

These steps are explained in more detail in the following pages.
