Technical Specifications CX300

CINEMA SERIES

PRODUCT INFORMATION

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.

CLOSE COUPLED ELECTRONIC PROCESSING™

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 iterative design process using EAW’s rapid data acquisi­tion facility and in-house multi-platform computer network.

CONFIGURATIONS

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 your cinema system.
