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.

OPERATION - INITIAL SETUP  
WARNING: A digital processor provides a wide range of signal processing parameters. The  
results of using incorrect or improper parameters with a loudspeaker can range from poor  
sound quality to damage to the loudspeaker. Be sure any settings you make do not cause the  
capabilities of the drivers in the loudspeaker system to be exceeded.  
5. 1  
Power On /Off  
CAUTION: Before powering on the processor, make all connections to the processor and  
ensure there is no audio signal present at the processor’s inputs.  
Use the UX8800’s rear panel power switch to turn the ac mains supply to the processor on and off.  
Always follow prudent audio system practices and procedures for powering on equipment by powering up  
all equipment in the direction of the signal flow order, meaning from the input to the output of the audio  
system. Power down the equipment in the reverse of this order.

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.

NAME  
IMPORTANT !!  
The Amp's Max Voltage and Amp Gain values you enter are CRITICAL in order for the  
UX8800 to provide the correct acoustic balance and limiter parameters. These values  
must match the actual performance of the amplifier connected to each Greybox's output.  
If these values do not match the performance, the loudspeaker or array may be voiced  
incorrectly, be over protected, or be under protected.  
7.5.3  
AMP GAIN  
Scroll through and select the Amp Gain for the amplifier connected to that output channel. The range is  
from 10 dB to 50 dB in 1 dB increments. This value is used by the UX8800 to determine the Output  
Channel gain and limiter threshold setting.  
The amplifier gain must be in dB, being 20 x log (input voltage / output voltage), the voltages being rms.  
The value you enter MUST account for any gain or attenuation between the UX8800 output and the  
amplifier input. Normally, the published gain specification for an amplifier is determined with its input  
level control at maximum. Setting an amplifier's input level controls to less than maximum, as is often the  
case to achieve good gain structure, changes the amplifier gain. In this case, the measure gain. Do not rely  
on a level control's attenuation markings.  
7.5.4  
MAX VOLTAGE  
Scroll through and select the Max Voltage (maximum rms voltage) for the amplifier connected to that  
output channel. This value is used by the UX8800 to determine the limiter threshold setting.  
The amplifier maximum voltage must be the rms level at clipping at the nominal impedance of the  
loudspeaker, being the square root of (maximum watts at nominal Z x nominal Z). Determine this from the  
amplifier specifications, calculation, or measurement.  
Page 17  
 
7.5.5  
LISTENER DISTANCE AND AIR LOSS PRE-EMPHASIS  
IMPORTANT !!  
In order for theAir Loss Pre-emphasis to be effective, the ambient temperature and  
humidity values MUST be manually entered using the UTILmenu on the UX8800's  
front panel. (See Sections 5.3.4 and 5.3.5.)  
If enabled, scroll through and set the Listener Distance (1 m to 256 m) from the array to the closest part of  
the audience area covered by the portion of the array to which the pre-emphasis is applied.  
The Listener Distance is a parameter of the Air Loss Pre-emphasis filter that compensates for high  
frequency air loss over distance. The parameters of this filter are calculated from the user-entered ambient  
temperature, relative humidity, and listener distance.  
While only a single distance is entered for theAir Loss Pre-Emphasis Filter, the audience covered by a  
given portion of an array or loudspeaker will vary in distance from the array. The  
recommendation for setting the distance to the closest listeners in this area  
is because there is far lower listener tolerance for excessive  
brightness than a lack of brightness. Thus, if the  
distance is set for the closest part of the  
audience area covered by the filtered  
portion of the array or loudspeaker,  
then the more distant listener will  
hear less bright sound. However, if  
the distance is set for audience further  
back in this area, then the sound for the closer  
listeners in this area will be excessively bright and likely annoying. In any case, you can adjust the  
brightness to taste by adjusting the distance parameter.  
NOTE: To bypass theAir-Loss Pre-emphasis filter: set the Listening Dist to 1 m.  
7. 6  
LEVEL (Input Channels A to D)  
Use the LEVELfunction to set Input Channel gain and polarity by selecting theAto D buttons.  
Level:  
Polarity:  
Scroll through and select the gain up to +/- 15 dB in 0.1 dB steps.  
Select the polarity: + or -.  
7. 7  
7.7.1  
X-OVER (Input Channels A to D)  
HPF FREQ AND LPF FREQ  
X-Over HPF (if enabled): scroll through and select the frequency. The range will depend on the  
particular loudspeaker model. This setting affects the entire loudspeaker.  
X-Over LPF (if enabled): scroll through and select the frequency. The range will depend on the  
particular loudspeaker model. This setting affects the entire loudspeaker.  
The X-Over HPF and LPF filters are typically used in either of two ways.  
1. Stand-alone Loudspeakers and Arrays:  
For full-range loudspeakers and subwoofers, the LF subsystem has an HPF enabled that  
is set to protect the loudspeaker from excessive LF signals that are below its operating  
range. Normally, leave HPF settings at their default values. This is always a 12 dB per  
octave Butterworth filter.  
For applications such as voice-only, fill usage, and similar, set a higher frequency HPF  
to restrict unwanted low frequency signals. This automatically changes the HPF filter  
from its normal 12 dB per octave Butterworth filter to a more appropriate filter, most  
commonly a 24 dB per octave Linkwitz-Riley filter.  
For subwoofers an adjustable LPF, 24 dB per octave, Linkwitz-Riley is enabled for their  
low-pass crossover filter.  
Page 18  
 
2. Loudspeakers and Arrays with Subwoofers:  
To use full-range loudspeakers and arrays with subwoofers, set the X-Over LPF and HPF  
filters to the desired subwoofer to full-range crossover frequencies. This automatically  
changes the HPF filters from their normal settings to a more appropriate filter, most  
commonly a 24 dB per octave Linkwitz-Riley filter.  
While the crossover frequencies are adjustable, the type and slope of the crossover filters  
are not adjustable. The reason for this is that the level of the subwoofers is rarely matched  
to that of the full-range loudspeaker. For example, it is not uncommon at rock ‘n roll  
shows for subwoofers to be operated at levels up to 12 dB higher than the full-range  
loudspeakers. The 24 dB Linkwitz-Riley filter provides a smooth summation and  
transition through the crossover region regardless of the level differences between the  
full-range and subwoofer sources. Other types of filters may cause notches or peaks  
through the crossover unless levels are precisely matched.  
7. 8  
EQ (Input Channels A to D)  
Use the EQ function to set the Input Channel equalization by selecting theAto D buttons. Each channel’s  
EQ section has 10 filters. Each EQ section has the following variable parameters. The available parameters  
depend on the selected Type.  
Parametric EQ  
Type:  
Sets the entire EQ section (filters 1 to 10) to In (active) or Out (inactive).  
Scroll through and select the type for each filter: Bell, 6 dB LoShelf, 12 dB LoShelf,  
6 dB HiShelf, 12 dB HiShelf, 6 dB HPF, 12 dB HPF, 6 dB LPF, or 12 dB LPF.  
Scroll through and select the bandwidth for each filter: 0.02 to 10 octaves.  
Scroll through and select the frequency for each filter: Variable from 20 Hz to  
20 kHz in 1/24th octave steps.  
BW:  
Freq:  
Gain:  
Filt:  
Scroll through and select the gain for each filter: +/- 15 dB in 0.1 dB steps.  
Sets the selected filter (1 to 10) to In (active) or Out (inactive).  
7. 9  
PROG  
The UX8800 has memory spaces for 50 user-savable and loadable programs for each operating mode  
(Loudspeaker Processor and System Processor).  
NOTE: The unit will only display programs stored in memory for the current operating mode:  
System Processor or Loudspeaker Processor.  
Load  
Scroll through existing programs stored in the processor memories to find and  
load the desired program. A program contains information for all processing  
parameters except for the mute settings. Programs can only be loaded for the  
specific operating mode in use.  
NOTE: While mute settings are not saved, the mute preferences set in the On Prgm Load setting in  
the UTILmenu will be used when loading a program.  
Save  
Scroll through existing programs stored in the processor’s memories and empty  
memories to find a destination to save the current processing parameters. Name  
the program to be saved. If a memory with an existing program is chosen,  
rename the program to be saved. This will replace the existing program saved  
into that memory.  
Delete  
Scroll through the existing programs stored in the processor’s memories and choose  
one to delete. You must confirm deletion before the program can be deleted.  
7. 10 DELAY (Input Channels A to D)  
Use the DELAYfunction to set Input Channel signal delay by selecting theAto D buttons. The input delay  
is normally used to set an overall delay for a loudspeaker or group of loudspeakers.  
Select the signal delay up to approximately 1200 ms in one sample (20.83 µs) steps. The delay is displayed  
in both milliseconds (2 decimal places) and distance (feet or meters according to the units settings).

The input meters indicate the signal level in dB below 0 dBFS (0 dB Full Scale), the clip level of theADC  
(analog to digital converter). An input meter still functions when its Input Channel is muted. Ideally, the  
highest levels of the signal should illuminate the -6 LED segment, but not the CLIP segment. Occasional  
flashing of the CLIPsegment may be sonically acceptable.

MAINTENANCE AND SERVICE  
10. 1 Maintenance  
The only routine and periodic maintenance for the processor is physical cleaning and performance testing.  
10.1.1 CLEANING  
Clean the exterior surfaces of the chassis as required, using a soft, dry cloth to remove any dust or dirt.  
Remove any dirt from the air intake holes on the side and top of the chassis. Remove any dirt accumulated  
on the ventilation fan grille.  
CAUTION: To avoid damaging the exterior finishes or internal circuitry do not use any liquid,  
cleaning solvents, or abrasives.  
While the interval between cleanings will depend on the frequency of usage and the conditions of use, it is  
recommended that cleaning be performed at least once a year. Clean more often if used in dusty or dirty  
conditions, such as part of a portable or touring system.  
10.1.2 PERFORMANCE TESTING  
Perform listening tests and/or formal measurements, checking all processor functions for proper operation.  
While the interval between testing will depend on the frequency of usage and the conditions of use, it is  
recommended that should be performed at least once every six months. Test more often if used in  
conditions that subject the unit to mechanical stress, such as part of a portable or touring system.  
10. 2 Ser vice  
There are no user serviceable parts inside the UX8800 processor. In case of failure, refer all servicing to the

Check that the cabling is a standard or crossover CAT-5 Ethernet cable and that the cable is  
functioning correctly. The U-Net ports auto-sense the cable configuration. The supplied Ethernet  
crossover cable can be used for interconnecting U-Net ports. Note: Control signals are  
automatically sent and received over U-Net connections.  
U-Net connection does not work Audio signal(s) not assigned to Sending and receiving audio over U-Net requires assigning Input Channel and Output Channels  
for audio  
the U-Net channels  
to the desired U-Net channels. In other words, there must be signals assigned to be sent over a  
U-Net channel in order to receive signals on that U-Net channel. Use the CH U-Net Output  
function for the Input Channels and Output Channels to send signals to U-Net channels. Use the  
CH Src function for the Input Channels to receive U-Net signals from U-Net Channels.

PURPOSE FOR GREYBOX FILES  
In Loudspeaker Processor mode, the UX8800 allows loading files with factory-determined processing for  
specific loudspeaker models and arrays. This processing includes equalization, crossovers, high and/or  
low pass filtering, signal delay, and level control. In addition, files with Gunness Focusing also include  
proprietary processing invented by EAW specifically for correction of inherent loudspeaker anomalies.  
Often, audio system designers, technicians, or end-users attempt to create loudspeaker processing from  
scratch using one of the several, excellent measurement systems publicly available. However, the systems  
and methods cannot duplicate what is involved for EAW engineers to create Greybox processor settings:  
•
•
•
•
Loudspeaker data far greater in quantity, types, precision, and accuracy (especially polar data).  
Use of proprietary analysis tools developed specifically for loudspeaker data.  
Use of proprietary Gunness Focusing algorithms for the processing.  
Extensive listening tests performed by a wider range of people over a much greater time period  
and under a much greater range of conditions.  
•
•
Controlled, laboratory conditions.  
Extensive knowledge in the application of loudspeaker data analysis and signal processing.

System Processor Mode Processing  
In System Processor mode, the UX8800 may appear similar to other digital signal processors. However, the  
processing algorithms used in the UX8800 differ from the normal, “textbook” algorithms used in digital  
processors. EAW developed new algorithms specifically tailored for digital audio processor hardware.  
FILTER RESPONSE EXAMPLE  
The accuracy and precision of the UX8800 filter responses can be compared to those using textbook  
algorithms. When applied to audio processing hardware, the latter do not provide textbook responses. The  
two graphs compare the results of EAW’s processing algorithms and standard “textbook” algorithms as  
used in well-accepted, digital signal processors. The frequency responses and phase response are for the  
UX8800 (lower curves) and a non-EAW processor (upper curves). The settings were two filters set for a 5  
dB boost, 1 octave bandwidth (Q = 1), at frequencies of 1 kHz and 15 kHz. There are several things to note:  
1. The upper curve is the upper curve becasuse its filter skirts extend somewhat beyond that of  
an ideal filter. In this case, the lower -3 dB point for the 1 kHz filter is actually over an octave  
below the filter frequency. The EAW response follows the response of an ideal filter.  
2. The shapes of both the 1 kHz and 15 kHz filter frequency and phase responses are different for  
the non-EAW processor. In contrast, the frequency and phase response shapes of the two EAW  
filters are quite similar. When overlayed, they prove to be virtually identical.  
3. Because of the difference in two non-EAW filter shapes, the response of the filters overlaps too  
much, resulting in an excessive boost in the 5 kHz to 10 kHz region.
