4-input by 8-output digital processor (48-bit/96-kHz)

UX8800 Digital Signal Processor

PRODUCT INFORMATION

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 EAW 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.
