Three-Way Hookup

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.
