When you use an active crossover to split the power drive to the loudspeaker
components, you gain a wide range of advantages, including:
1. Increased gain because the insertion loss of passive crossover networks is
eliminated.
2. Consistent power bandwidth: power bandwidth is changed in multi-way pas-
sive systems if transducers change impedance or vaporize (blow up).
3. Levels can be matched
more accurately to the
components.
4. Improved dynamic
range.
Active crossovers for
Crown amps are available
in both PIP and SST mod-
ules (see your Operation
Manual for details about
available options for your amplifi er).
Figures 1.27 through 1.29 illustrate typical systems using active crossover
modules.
