As is true of all professional loudspeaker systems, the performance of the NTS250 Series loudspeakers
depends on amplifiers delivering an adequate supply of clean power. To maximize performance, the
loudspeakers have powerful, built-in, high-efficiency amplifiers. NTS250s are bi-amplified, meaning
each woofer has its 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. If suspended, design and install a rigging or mounting system to support the array in its intended
location and aimed in the desired direction.
2. Connect a line-level audio signal to the loudspeakers in the array.
3. Connect the loudspeakers to an AC mains supply as specified on the loudspeakers.
4. Connect the computer control to the loudspeaker’s USB port.
5. Set-up and adjust overall system gain and signal processing, as needed to maximize the array's
performance for the application.
6. Provide training to operate the loudspeakers within their limits.
7. 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.
5.1.3 COMPUTER REQUIREMENTS
EAWPilot and NTS250 Array Wizard require an IBM compatible PC with the Windows® 98,
Windows® 98SE, Windows® 2000, Windows® ME, Windows® XP, and Windows NT® and Vista®
operating systems.. It is not designed to work with Windows® 3.x, Windows® 95, or Macintosh®
operating systems.
6 ELECTRICAL INSTALLATION
6 . 1 A C M a i n s
There are two NTS250 models, differing only in the AC mains supply:
NTS250 (115 V) Nominal AC mains: 100 V to 120 V, 50 Hz to 60 Hz
NTS250 (230 V) Nominal AC mains: 220 V to 240 V, 50 Hz to 60 Hz
