7 OPERATION - LOUDSPEAKER PROCESSOR MODE

IMPORTANT NOTE: In this mode only certain functions and parameters are available for user

adjustment. These will vary depending on the input configuration and the specific loudspeaker or

array selected by the user.

7.1 Introduction

In Loudspeaker Processor mode the user can select from a list of specific EAW loudspeaker models and

arrays with factory-determined processor settings. This processing is not user accessible or adjustable.

EAW has designed the processing for each product listed and uploads it into specific, read-only memories

in the UX8800. As new loudspeaker products are released and older products are provided with Gunness

Focusing, these new settings can be uploaded into the UX8800.

The user configures one or more Input Channels by selecting a specific loudspeaker product for each. The

user then assigns the required number of outputs for each loudspeaker to that input channel as output “legs.”

In Loudspeaker Processor mode the user can also configure one or more inputs for generic signal

processing and assign it to one or more unused outputs as needed. This provides the same capabilities for

those channels as if they were in System Processor mode.

7.1.1 GREYBOX PROCESSING

When a specific loudspeaker or array is selected, there are three types of signal processing. The first two are

the processing for the Output Channels and are not user adjustable. The third type is input channel

processing that is user-adjustable.

1. Standard Processing: This consists of standard, digital processing functions, including signal

delay for driver time alignment, polarity, gain, crossover filters, and high/low-pass filters.

These settings are fixed at the factory.

2. Gunness Focusing: This consists of a precise and highly complex filter specifically designed

to correct physical and electro-acoustic anomalies inherent to the design of a loudspeaker and

which cannot be corrected using conventional digital signal processing functions. In order to

be correctable, each of these anomalies must remain constant with listener direction, signal

level, environmental differences, and loudspeaker age. These anomalies are grouped together

and treated using a single, though quite complex, Gunness Focusing filter that addresses the

entire audible frequency range. These settings are fixed at the factory.

3. Input Processing: This consists of standard digital processing functions, including signal delay

for overall delay, gain, polarity, EQ, and high/low-pass filters. These settings are user

adjustable and affect all Output Channels (legs) assigned to each input and thus the overall

performance of the loudspeaker.

7.1.2 GENERIC PROCESSING

When generic processing is selected for an Input Channel, the Input Channel and Output Channel

processing is configured for standard digital processing functions, including signal delay, gain, polarity,

EQ, limiting, and high/low-pass filters.

NOTE: When set for generic processing, the Input Channel processing can be adjusted using the

UX8800 front panel. However, Output Channel processing can only be adjusted using EAWPilot

software. It cannot be adjusted from the UX8800 front panel.

7.2 Select Loudspeaker Processor Mode

1. Select the UTIL function.

2. Scroll down to and select: Mode

3. Select: Loudspeaker Processor. This will reboot the processor and reset all parameters to their

default settings for this mode.
