19.4.4 HPF/LPF - Design (Mesa EQ Only)
Crossovers, EQ, and All Pass filters are not available on the Mesa EQ HPF/LPF - DESIGN screen. The same
HPF/LPF types are available for Mesa EQ as listed in Table 19-2.
19.4.5 Levels - Design
The data on the LEVELS - DESIGN worksheet is entered by typing the appropriate numerical value into a cell
on the worksheet. An error message will be displayed if the value is invalid or incorrect.
To set polarity through the LEVELS - DESIGN worksheet, enter either + (positive) or – (negative) in the
polarity field. The polarity of each output can be independently locked using the LOCK POLARITY? field,
which is only available via this worksheet.
To lock polarity of an output, change the value in the associated LOCK POLARITY? field to Y. The example
Module in Figure 19-16 has the polarity of all channels locked except for the input and lowest output.
Figure 19-16: Locking Polarity
When the Module is locked, the worksheet will appear as shown Figure 19-17. In this example, output
polarity for channels 2, 3, and 4 will be locked even in Designer Mode.
