UX8800 Preliminary Specifications Digital Signal Processor
Features and Benefits
•
Two operational modes.
System Processor - All signal processing is user-adjustable.
Loudspeaker Processor - Preset signal processing for EAW
loudspeakers with Gunness Focusing™ to optimize
performance.
•
Comprehensive, intuitive front panel control makes computer
control unnecessary for most adjustments.
• U-Net – EAW-designed signal and control networking between
UX8800s and other U-Net enabled products.
• Digital inputs to reduce A/D & D/A stages.
• EAWPilot software for comprehensive computer control.
• Filter parameters are compatible with EAW’s modeling and
alignment software for optimized performance.
Description
The UX8800 provides a complete suite of state-of-the art, digital
signal processing tools. Additional capabilities and features set the
UX8800 apart as the head end processor for large systems with a
variety of output channels and for processing specific, EAW
loudspeakers.
In System Processor mode, user-adjustable functions include the
expected range of processing tools, such as EQ filters, delay, gain,
crossovers, and polarity. However, these functions are
implemented using custom-designed algorithms to optimize their
usefulness when applied to loudspeakers. For example, unlike
many bell filter designs, the UX8800’s produce a flat frequency
response when reciprocal cut and boost filters are overlaid. Also, to
more accurately calculate signal delay distances, a temperature
setting compensates for sound speed differences.
In Loudspeaker Processor mode, preset processing is available for
specific EAW loudspeakers and loudspeaker arrays. The UX8800
hardware is designed to implement EAW’s innovative Gunness
Focusing™ as part of the preset processing to correct loudspeaker
anomalies that cannot be corrected with conventional digital
processing. Advanced limiting is designed to maintain sound quality
while achieving maximum output levels based on amplifier outputs
and. An ambient humidity setting provides appropriate air loss
equalization based on listening distances. While the output settings
are locked to prevent inadvertent or purposeful modification, the
user retains control of input gain, EQ, signal delay, and polarity for
the entire loudspeaker. This mode’s simplicity makes the UX8800
practical for entry level users and fast to operate for experienced
users, providing a high degree of system consistency while retaining
all necessary, user adjustable, alignment controls.
The UX8800 uses standard Ethernet protocol and CAT-5 cabling for
computer control using the custom EAWPilot software. A unique
design that permits plug-and-play Ethernet communication without
having to deal with problematic IP addresses. In addition, both audio
and control signals can be transmitted between additional
processors and other EAW products using the built-in, 32-channel,
U-Net network and standard CAT-5 cabling. Up to 254 devices can
be linked using U-Net, all controlled by EAWPilot.
Two year warranty.
