Description
The UX3600 provides a complete suite of state-of-the-art digital signal
processing tools. Advanced capabilities and features set the UX3600 apart
from other processors in its class. This high end processor controls sound
systems with a variety of output channels and also delivers optimized
processing of specific EAW loudspeakers.
Built-in System functions include EQ filter, 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 UX3600’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
permits compensation for sound speed differences.
Loudspeaker preset processing is available for specific EAW loudspeakers
and loudspeaker arrays. The UX3600 implement EAW’s innovative Greybox™
settings, including EAW Focusing™, as part of the preset processing to correct
loudspeaker anomalies that cannot be corrected with conventional digital
processing. Advanced limiting maintains sound quality while achieving
maximum output levels based on amplifier outputs. An ambient humidity
setting provides appropriate “air loss” equalization based on listening
distances. While the output settings in Greyboxes are locked to deliver
optimal loudspeaker performance, the user still retains control of input
gain, EQ, signal delay, and polarity for the entire loudspeaker. This mode’s
simplicity makes the UX3600 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 UX3600 uses standard USB protocol and cabling for computer control
using the custom EAWPilot software. Up to 50 user-defined presets can be
save into device non-volatile memory. Two year warranty.

UX3600 TECHNOLOGY
UX3600 Design Challenges: The goal for UX3600 digital signal processor was to provide a comprehensive set of digital
processing tools in a 3 input by 6 output processor. In addition, the processor’s hardware had to be able to implement
EAW Focusing™ in order to provide preset, factory-optimized processing for specific EAW loudspeakers. This would include
those intended for standalone use and those normally used in arrays. The preset processing allows unused input and
output channels to have standard processing for other uses.
EAW Focusing™: Using innovative analysis tools and methods developed by EAW, specific, long-standing, loudspeaker
problems were isolated and analyzed as to their solutions using DSP. However, the desired complex filter responses
required accuracies grossly lacking in conventional DSP filters based on the Bilinear Z Transform (BZT). These filters sacrifice
response accuracies in the upper audible octaves to avoid mathematical difficulties involving the Nyquist frequency. Using
standard algorithms can result in filter response magnitude errors of over 15 dB, with equally flawed phase performance.
Using FIR (Finite Impulse Response) filters would have resulted in latencies in excess of acceptability for real time use. EAW
Focusing uses EAW-developed filter algorithms that avoid these issues while providing the exact, complex, filter responses
required to correct the loudspeaker problems.
EAW Focusing is implemented in the UX3600 for many EAW loudspeaker models. Of particular note are EAW array
loudspeakers. EAW Focusing not only optimizes the performance of the individual loudspeakers, but it also optimizes the
integration of adjacent loudspeaker outputs and the off-axis performance of entire arrays.
EAW Focusing Example: Figure 1 shows the spectrogram of an ideal, point-source loudspeaker. Figures 2 and 3 show
two different spectrograms of a 2-way loudspeaker optimized with conventional digital signal processing (DSP) and
conventional measurements. In Figure 2 the time domain performance is emphasized. In Figure 3 the frequency domain
performance is emphasized. In both cases there is significant energy to the right of the main energy spectrum compared
to the ideal loudspeaker shown in Figure 1. These are all caused by inherent, mechanical properties of both the cone LF
driver, the HF compression driver, and the HF horn itself. Although the frequency response (not shown) is nearly an ideal,
flat line, these anomalies obviously exist in spite of the conventional processing. Because the usual measurements and
corrective filtering lumped the undistorted signal and the anomalies together, the flat response is actually a combination
of the energies from both. Anomalies like these are generally described as coloration and are responsible for why two,
similar, flat-response loudspeakers can sound quite different.
In contrast, the result of applying EAW Focusing to this same loudspeaker is shown in Figure 4. The anomalies in both time
and frequency are largely gone, making the spectrogram in Figure 4 look quite similar to that of the ideal loudspeaker
in Figure 1. While the frequency response is also nearly an ideal, flat line, it is almost entirely a result of reproducing the
energy from flat input signal.
Summary: EAW’s engineering efforts resulted in the UX3600 digital signal processor which provides complete
user control as well as factory-optimized, Gunness Focusing settings for EAW standalone and arrayed loudspeakers.
Userfriendly, advanced, processing functions and plug-and-play audio/control networking facilitate its use for first-time
DSP users, seasoned professional operators, system designers, and audio aficionados all over everywhere. In keeping with
the performance of EAW loudspeakers, the UX3600’s sonic performance is superb.
Figures 1 to 4 (top to bottom)
SPECTROGRAMS: EAW’s proprietary spectrograms show the spectrum or frequency content of sound (vertical axis) and its variation in time (horizontal axis), the colors
representing intensity. The width of the data reflects the size of the sliding time window applied to the data, which increases in size with lower frequency. The “data” in
the upper right is simply a limitation of the spectrograph’s mathematics and has no relevance.
