The CX300 is a dedicated cinema electronic crossover, with a

specific configuration available for each EAW cinema screen channel
system. It is a cost-effective, single rack-space, analog electronic
crossover designed for use in biamplified or triamplified applications.
The unit is a three-channel design, so a single CX300 will provide
crossover, equalization, and time-offset functions for a Left, Center,
and Right cinema system. This removes the burden of “setting up”
from the end-user and assures optimum system performance.

The concept of Close Coupled Electronic Processing™ (CCEP™) is
central to the EAW design process. EAW engineers integrate elec­tronic signal processing into the total loudspeaker system, but we
recognize that electronics can only improve performance after all
other electro-mechanical factors have been optimized. The CX300
processor incorporates functions such as complex asymmetrical
crossover filters, phase compensation, and parametric equalization.
All of these parameters are configured for a particular loudspeaker
system in an interactive design process using EAW’s rapid data
acquisition facility and in-house multi-platform computer network.

Each CX300 processor is configured (Close Coupled™) to a particular
EAW cinema screen channel loudspeaker system. Please refer to the
information below to find the appropriate CX300 processor for your
application. If you have any questions please contact an authorized
EAW sales agent, or the factory itself, to be certain that you order
the correctly configured processor for you cinema system.
