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 EAWloudspeaker 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.
