NTL720 3-Way Line Array Module


The NTL720 delivers the three-way design, power and fidelity of the KF Series line array systems in an ultra-compact self-powered enclosure weighing less than 54 lbs. (24.7 kg). The exceptional output capability in a small, lightweight package allows NTL720 to fill a range of application requirements from small theaters and houses of worship to live concerts and corporate events.

NTL720 features dual 6-in LF cone transducers in a sealed enclosure which deliver exceptional horizontal pattern control via tuned spacing. Dual 6-in MF cone transducers are mounted in a large horn that fills virtually the entire face of the enclosure, maximizing horizontal pattern control as well as driver efficiency. Six 1-in dome tweeter HF transducers share the same horn with the MF transducers; tightly stacked in the center of the enclosure, the six HF transducers leverage beneficial interaction to generate extraordinary output. The three subsystems feature a symmetrical configuration, allowing coherent summation and even response across the nominal 110 degree (h) by 12 degree (v) coverage area.

The NTL720 Flybar works on its own or, via an adapter can attach to an NTS250 dual 15-in subwoofer. The NTL720 Flybar also features adjustable footpads on the “top” so that users can invert it and use it to safely ground-stack up to six NTL720 modules. The ingenious rigging system allows users to select a range of module-to-module angles, which simply snaps into place, creating a safe, strong connection between modules. In the unlikely event of a module failure, users can quickly and easily remove the module from within the rigging structure and replace it without ever disassembling the array.

EAWPilot control software provides comprehensive DSP control as well as monitoring of amplifier status. Input selection is a choice of analog, AES left/ right, and EAW’s proprietary U-Net. Communication connection options include U-Net and a USB port on the back panel for interfacing with the DSP.

KF LINE SOURCE VOICING UPDATE Leveraging data and experience from development of Adaptive Systems™, updated Greybox™ processing enhances performance of NTL720 incorporating improved equalization, crossover, Focusing™ and limiting parameters for even better system performance without any physical changes. The update brings improved warmth and clarity to the NTL720, while making it sonically more consistent with KF730, KF740 and Adaptive Systems. Updated firmware is available here.
