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.

3.1 UX8800 Description

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 EAWloudspeaker 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.

3.2 Features and Benefits

• 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.

3.3 Networking Capabilities

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.
