To solve this dilemma, the company undertook development 

of custom (and rather radical) DSP algorithms specifically 

engineered to provide the required filters for correcting 

loudspeaker anomalies. The resulting filters had to possess the 

required precision and accuracy in both the frequency and time 

domain. At the same time, any uncorrectable anomalies would 

have to be ignored by the filters.

This advanced processing, now called Gunness Focusing, cannot 

be applied “as is” to just any loudspeaker, let alone be something 

that even the most astute of users can set up. The anomalies and 

resonance problems cured by Gunness Focusing are very specific 

to each loudspeaker design.

Thus, the internal physical details must be known, the anomalies 

must be carefully analyzed, with appropriate filters custom 

designed by EAW and implemented via the UX8800 processor – 

or, in the case of the NTL720, it’s incorporated within the system.

CONTROL & MUCH MORE

EAWPilot control software provides comprehensive DSP control 

as well as monitoring of amplifier status for each NTL720 module 

in an array. And it does much, much more. When connected, all 

loudspeakers in the audio system comprise a network in which 

EAWPilot recognizes each individual loudspeaker as well as 

arrays of loudspeakers acting as a single unit.

The roots of this software package stem from the KF900 project’s 

optimization program, FChart, which uses high-resolution 

measurements of each individual driver in an array to predict and 

optimize total array performance. EAWPilot employs this same 

approach to control multiple loudspeakers in a total system 

environment.

Not only does EAWPilot assist in optimizing a wide range of 

loudspeaker and array parameters, but its Wizard modeling 

software helps in automatically configuring array DSP for optimal 

performance fitting specific audience areas, greatly simplifying 

system setup and alignment. This even extends to providing 

the user with input on building optimum array structures and 

selecting correct pickpoints on the array flybars for a given array 

configuration. (

Input selection provided on NTL720 cabinets is both simple 

and flexible – the user has a choice of analog, AES left/right, and 

EAW’s proprietary U-Net. Drawn from the UX8800 and other EAW 

products, U-Net provides full digital control of each device in a 

system, including audio signal, processing parameters, routing – 

in addition to accommodating EAW Smaart tuning and analysis 

platform. (
