hd ML24Beam – BeamForming Stick.

The hd ML24Beam is equipped with 24 shielded 2″ broadband speakers, each with 75 W amplifiers and the latest DSP generation. It offers great potential for improving the sound distribution in complex architectures and strongly reverberant rooms. The goal is to focus the sound only on auditory surfaces, while surfaces that cause unwanted reflections and produce disturbing diffuse sound to be shaded. This leads to a much better speech intelligibility and a first-class listening experience for every listener, allows an inconspicuous positioning of the speakers in previously inappropriate positions, as well as a flexible adaptation of the speaker radiation characteristics to different applications.

The hd ML24Beam’s true 1-way design eliminates interference in the important mid-range frequency range because there is no shadow from superior speakers, and no crossover network adversely affects the radiation, enabling clean implementation of beamforming algorithms. The result is an extremely homogeneous horizontal radiation of 100° and outstanding sound quality for speech and music, extended dynamics.

The specially developed electronic unit features a high-performance DSP, which exploits all possibilities of modern signal processing to realize extensive beamforming algorithms. Using the intuitive software hd LevelZ, the sound field can be simulated and optimized to achieve the best possible result. The ultra-compact 80mm width makes the hd ML24Beam the narrowest beamforming speaker on the market, almost invisible in fixed installations. The electronic unit is integrated into the housing of the loudspeaker and is optimally protected by the continuous fine-structured design grid with backed acoustic foam and ensures an unobtrusive integration into any room architecture. The continuous metal rail on the back of the aluminum profile allows the use of M6 square nuts for attaching a wall mount adapter or the use of the tripod adapter for mobile applications. M6 threads on the top and bottom allow wall mounting with L mounting brackets in the smallest space requirement
