As is true of all professional loudspeaker systems, the performance of the NTL720 Series loudspeakers
depends on amplifiers delivering an adequate supply of clean power. To maximize performance, the
loudspeakers have powerful, built-in, high-efficiency amplifiers. NTL720s are tri-amplified, meaning
their LF, MF, and HF subsystems each have their own amplification and internal DSP. Even though
extremely lightweight, these amplifiers provide the exceptionally high output capabilities required for
professional applications.

You will need to perform the following general tasks to properly put the loudspeaker into service. The
details for each task are provided in this manual.
1. Design the array using the NTL720 Array Wizard.
2. Design and install a rigging or mounting system to support the array in its intended location and
aimed in the desired direction.
3. Connect a line-level audio signal to the loudspeakers in the array.
4. Connect the loudspeakers to an AC mains supply as specified on the loudspeakers.
5. Connect the computer control to the loudspeaker’s USB port.
6. Set-up and adjust overall system gain and signal processing, as needed to maximize the array's
performance for the application.
7. Provide training to operate the loudspeakers within their limits.
8. Provide regular inspection and maintenance to maintain the integrity of the installation and the
performance of the loudspeakers.

5.1.1 EAWPILOT
EAWPilot is software for controlling the digital signal processing (DSP) for multiple EAW products.
Use the EAWPilot to apply user-adjustable signal processing to the overall array. The interface
provides standard DSP functions, including parametric equalization, high/low shelving, low- and
high-pass filtering, level, and signal delay.
5.1.2 NTL720 ARRAY WIZARD
The NTL720 Array Wizard’s primary function is to determine the configuration that will provide the
best vertical performance for a given application. Various venue dimensions are user-entered that
allow calculating the optimum array configuration. Given the venue dimensions, the program can work
in either of two basic ways, with both displaying the resulting coverage.
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.
