    NTL720s are normally connected to the computer as a complete array. This is done by connecting the computer to one NTL720 via its USB port, or via the U-Net connection on an EAW UX8800 processor. The other NTL720s are connected to this one and each other using EAW’s U-Net network. The NTL720 connected to the computer (or UX8800) functions as a gateway to the U-Net network allowing EAWPilot to control individual elements within the array and the entire array as a whole.

    Note: EAWPilot and the NTL720 Array Wizard can be found in the Downloads/Software section of the EAW website (www.eaw.com). It’s a good idea to check the website periodically for updates to these software applications.

    Automatic Mode: The interface will calculate the optimum number of enclosures, enclosure splays, array aiming angle, fly-bar pick point and user-control settings. This can also be done for a given inventory of NTL720s. Additional, user-variable criteria are provided for application-specific output levels and for level consistency for near-to-far listeners. Manual Mode: This provides complete control over the array’s configuration.

    7.2.2 GUNNESS FOCUSING™ Developed by the EAW engineering team (and named after its inventor, David Gunness), Gunness Focusing uses DSP technology to eliminate the traditional characteristics of “honk” and “splashiness” that can plague horn-loaded loudspeaker designs. The honk of a horn is normally heard in the lower frequencies of its band pass, while splashiness (an attribute of compression drivers) is usually heard in the highest frequencies and obscures the fine detail in instruments, such as cymbals.
