3 INTRODUCTION
Congratulations on purchasing the innovative UX8800 digital signal processor (DSP) from Eastern
Acoustic Works. While designed with the fundamental principles of close-coupled processing used since
the first MX Series Processors in the 1980s, the UX8800 uses EAW’s latest advances in digital technology
to provide optimum signal processing and management of EAW loudspeaker systems.

The UX8800 is a 4-input, 8-output digital signal processor that operates in either of two modes:
System Processor:
The UX8800 functions as a user-controlled, digital signal processor for
loudspeakers or for other applications requiring similar processing functions.
Loudspeaker Processor:
The UX8800 functions to provide sophisticated, EAW-engineered
digital processing for specific portable and installed EAW loudspeakers.
In System Processor mode, the UX8800 provides a complete suite of state-of-the art, digital signal
processing tools, including 10 EQ filters and signal delay (up to 1200 ms) for each input and output,as well
as gain, polarity, limiting, and crossover filters.
In Loudspeaker Processor mode, one can create up to four different EAW loudspeaker processors for
specific EAW loudspeaker products or loudspeaker arrays. These are referred to as “Greyboxes.” This term
comes from certain parameters not being user adjustable (“black-boxed”), certain parameters being user
adjustable (“white-boxed,” as it were), with the combination of black/white being grey. Greybox settings
consist of preset, EAW-engineered processing parameters for the crossovers, equalization, limiting, and
other settings as an integral part of that loudspeaker’s design and operation. These settings include EAW’s
digital processing invention called Gunness Focusing™. In addition, preset limiting parameters are
designed to maximize sonic performance during active limiting while providing robust driver protection.
These preset parameters are locked down to prevent inadvertent or purposeful modifications. However, the
user retains control of gain, input EQ, signal delay, and polarity for each Greybox loudspeaker.
The simplicity of the Loudspeaker Processor mode makes the UX8800 practical for entry level users and
fast to operate for professional users. This function provides for a high level of system consistency while
retaining all necessary user alignment controls.

•
Multiple Mode operation – Allows use as standard system processor or as dedicated
loudspeaker processor.
•
“Greybox” operation – Complete processing presets for EAW loudspeakers provides ease of
setup, consistency, and interoperability between EAW products and systems.
•
Comprehensive and intuitive front panel control – Access to operational parameters making
computer control unnecessary for simple and quick adjustments.
•
U-Net – EAW-designed signal and control networking between U-Net enabled products.
•
Digital inputs (U-Net and AES/EBU) – Reduces the total number of A/D & D/A stages.
•
EAWPilot software – Comprehensive software control of all hardware parameters.
•
Gunness Focusing capable – Implements Gunness Focusing for specific EAW loudspeaker
systems using the “Greybox” mode.
•
All filter parameters are compatible with EAW’s measurement and modeling software - Allows
the creation of advanced array processing.
•
Advanced Greybox Limiting - Provides more robust driver protection and better sonic
performance based on specific EAW driver and loudspeaker performance characteristics.

Standard Ethernet protocol and cabling is used to communicate with and control the processor. Both audio
and control signals can be transmitted between additional processors using the built-in U-Net network and
standard CAT-5 cabling with RJ-45 connectors. Up to 254 UX8800 processors can be linked using U-Net
so that all processors can be controlled by EAWPilot. The wiring configuration for U-Net can be a daisy-
chain (serial), a star, or a circular loop.
