The new EAW NTL720 is a self-powered line array loudspeaker system featuring a true three-way design and numerous other EAW patented and proprietary technologies housed in a compact (9.4x24x14.3 inches) and low-weight (less than 50 pounds) package.
The entire enclosure face of each NTL720 module is filled by a full-sized mid/high horn providing 110×12-degree (HxV) dispersion. High frequencies are produced by six 1-inch dome tweeters configured in two vertical columns (each with three tweeters) mounted on a manifold that feeds a single slot in the center of the horn. Flanking the HF section, dual 6-inch cone woofers handle the MF range, also loading onto the horn, with minimal space between the MF and HF components.
The LF section features EAW’s proprietary Phase Aligned approach. Both 6-inch LF drivers are positioned in a side-mounted, “figure-8” configuration that extends horizontal pattern control while directing more acoustical energy on-axis. The response of the MF drivers is also extended down to 100 Hz.
The onboard self-powering technology includes three individual modified 500-watt Class-D (digital) amplifier modules, each tailored for its respective subsection (LF, LF/MF and HF; all 4-ohm loads). Each amplifier module is accompanied by its own precisely matched digital signal processor. Headlining the DSP is EAW’s Gunness Focusing™ alignment and driver-processing algorithms.
EAWPilot control software provides comprehensive DSP control and monitoring of amplifier status; when connected, all NTL720 loudspeakers comprise a network in which EAWPilot recognizes each individual loudspeaker, as well as arrays acting as a single unit. Not only does EAWPilot assist in optimizing a wide range of loudspeaker/array parameters, but its Wizard modeling software helps in automatically configuring array DSP for optimal performance fitting specific audience areas, simplifying system setup and alignment.
The user has a choice of EAW’s proprietary U-Net, as well as analog, AES 1 and AES 2. U-Net provides full digital control of each device in a system, including audio signal, processing parameters and routing, in addition to accommodating the EAW Smaart tuning and analysis platform.
Communication connection options also include U-Net and a USB port on the back panel for interfacing with the DSP. Each back panel also offers HF boost and nearf-ield contour controls, along with a range of LED indicators for signal, limiter, clip, input selection, U-Net status, amplifier status, HF boost engagement and near-field contour engagement.
The proprietary FastLatch™ integral rigging system provides an easy, convenient “hinge-and-latch” approach, with the essential components being two heavy-duty hinge mechanisms on the back of each cabinet and a latch mechanism on the underside of each cabinet.
Splay angles (a choice of 12, 9, 6, 3 and 0 degrees) are easily selectable by carrier brackets that accompany the hinges. And the flybar can also be used as a stable, safe groundstack platform.
The rigging design also allows individual components and even entire modules to be replaced within built array structures, whether flown or stacked. Two plug connectors that directly connect the amplifier module to the PCB inside of the cabinet ensure a solid, lock-tight fit and eliminate cable connections. NTL720 cabinets are finished with EAW’s durable RoadCoat™ weather-resistant textured finish that is scratch-resistant, and the grille is durable aluminum.
