Associating Measurements With Filter Channels

After adding filter channels, measurements can be associated with each channel. Suppose you have four subs, and the mains were measured together as one, with both mains and subs measured at four listening positions. You might have measurements named as follows:

MLP:Sub 1
MLP:Sub 2
MLP:Sub 3
MLP:Sub 4
Pos 2:Mains
Pos 2:Sub 1
Pos 2:Sub 2
Pos 2:Sub 3
Pos 2:Sub 4
Pos 3:Mains
Pos 3:Sub 1
Pos 3:Sub 2
Pos 3:Sub 3
Pos 3:Sub 4
Pos 4:Mains
Pos 4:Sub 1
Pos 4:Sub 2
Pos 4:Sub 3
Pos 4:Sub 4

For each channel defined in the Config View, right-click its Measurement Associations category node and choose Associate Measurements from the context menu. This will open up a dialog box showing the measurements available for association. Using the example of the measurement names above, since each measurement name contains the name of its corresponding sub (or mains speaker as applicable), this association of measurement to channel is straightforward. For instance, all "Sub 1" measurements above could be associated with the "Sub Channel 1" channel, all "Sub 2" measurements could be associated with the "Sub Channel 2" channel, and so on. Only the measurements that are currently available for association will be shown in the dialog box. For example, mains measurements cannot be associated with sub channels and vice versa. Also, once a measurement is associated with a channel, it is considered "used up" for this particular purpose and cannot be associated with any other channel. Assuming no extraneous measurements were imported, after doing your measurement associations, all imported measurements should be associated with either a mains or sub channel.

See the tutorial for an example of associating measurements with filter channels.
