19.4.3.3 Linear Phase Crossover Types
The following HPF/LPF types are allowed for Linear Phase 2-Way and 3-Way Module crossover points only
(i.e. not the HPF on the lowest output channel or the LPF on the highest output channel for the Module).

Linear phase crossovers require both sides of the
crossover point to be the same crossover type.
Therefore if the one side of the crossover is
changed, the other side will change automatically.
19.4.3.4 Linear Phase Alignment Delay
Unlike most values in the worksheet, ALIGNMENT DELAY is a Module-based value, not a channel-based
value. Therefore, when ALIGNMENT DELAY is changed for any channel, all other channels of that Module
will be updated automatically.
Linear Phase 2-Way and 3-Way Modules provide six settings: 1.25 ms, 2.5 ms, 5 ms, 10 ms, 20 ms, 40 ms.
Linear Phase Brick Wall 4-Way Modules provide four settings: 3.15 ms, 6.29 ms, 12.58 ms, 25.17 ms.
19.4.3.5 Output EQ Types
Table 19-5 shows the abbreviations for adding output EQ filters via the XOVER - DESIGN worksheet, along
with associated default values.
