LAS Gradient Beam Technology Powed Loudspeaker

This product leverages in-depth research on spatial acoustics and the radiation characteristics of sound waves in both vertical and horizontal planes. Combining physical waveguide design with Digital Signal Processing (DSP), it achieves precise sound field control. Physical directional waveguides suppress unwanted side lobes for desired directivity. Horizontally, it generates three beams with different coverage angles for near, mid, and far-field, with independently adjustable sound pressure levels. Vertically, asymmetric radiation technology, utilizing DSP progressive delay and specialized acoustic structures, creates a downward tilt, enhancing sound field uniformity, suppressing ceiling reflections, and significantly improving speech intelligibility, especially in reverberant environments. It is ideal for large and medium-sized venues like command centers, lecture halls, places of worship, transportation hubs, lobbies, convention centers, and museums.

1. • Precise Directivity Control: Employs directional waveguide technology to effectively suppress unwanted side lobes and achieve the intended directivity pattern.

2. • Horizontal Gradient Beams: Three independent beams (Near-field: 160°, Mid-field: 100°, Far-field: 60°) cover respective zones. Narrower beams project further, wider beams cover broader areas. Sound pressure intensity for each beam is individually adjustable.

3. • Adjustable Near-Field Directivity: DSP allows adjustment of the near-field beam's horizontal coverage angle, enabling precise sound targeting towards desired areas and reducing radiation towards reflective surfaces like walls, thus enhancing speech clarity.

4. • Asymmetric Vertical Radiation: Utilizes DSP progressive delay and specific acoustic design to create a downward radiation tilt, significantly reducing upward sound energy and ceiling reflections. This ensures even front-to-back sound coverage without physical downward tilting of the enclosure, maintaining aesthetic integration while delivering clear, direct sound.

5. • Flexible Input Options: Supports AOIP network audio input (mainstream protocols), alongside analog and digital audio inputs, which can be used simultaneously.

6. • Convenient Network Management: Devices can be managed and configured via a standard network switch.

7. • Powerful DSP Software: Features an intuitive interface for comprehensive control, including beam steering, 7-band EQ adjustment, high-pass/low-pass slope filtering, input level control, mute, preset saving/recall, and system settings.

8. • High-Stability Amplifier: Incorporates a multi-channel, high-reliability digital power amplifier.

9. • Dedicated Full-Range Drivers: Utilizes specialized 3.5-inch full-range drivers for mid/far-field and 2-inch full-range drivers for the near-field, ensuring scientific sound wave coupling and delivering clear, transparent audio quality.

10. • Elegant Enclosure Design: Features a slender wooden cabinet available in black or white, designed for seamless integration into various environments.
