Multi-Sub Optimizer Tutorial (page 8)

Associating Measurements With Filter Channels

To perform an optimization, MSO needs information about which imported measurements are associated with which sub or main speaker. Since each independently-measured sub or main speaker is associated with an individual filter channel, you accomplish this by associating measurements with filter channels. The following assumptions apply:

To associate the main speaker measurements with Mains Channel 1, select the Measurement Associations icon under Mains Channel 1. Right-click and choose Associate Measurements from the context menu. All the main speaker measurements are shown in the dialog. Check all of them and click OK. You will now see four icons corresponding to the four main speaker measurements (that is, the main speakers at four listening positions). These icons are located under Measurement Associations, which in turn is located under Mains Channel 1. This is illustrated below.

Next, associate the Sub 1 measurements with Sub Channel 1. Right-clicking on Measurement Associations under Sub Channel 1 and choosing Associate Measurements gives the following dialog box:

There should be a total of four measurements involving Sub 1, showing up as every fifth measurement. Select the four measurements ending in _sub1.frd and press OK. Repeat this process for each of the three remaining sub channels. Each time you invoke the Associate Measurements dialog for a sub channel, the measurements you previously associated with a channel will have been removed from the list. A measurement cannot be associated with more than one channel. When done, the Config View should look something like this (Filters nodes have been collapsed for clarity):
