The hd ML-Series is a product family of very compact LineArray Systems, specially designed for top quality reproduction of both, music and speech. The speaker column´s slim, unobtrusive design integrates seamless into room architecture and stage areas appealing to event organizers, agencies and audiences. In the hd ML-Series special designed 2” neodymium drivers produce sound with accurate cylindrical dispersion characteristics in the whole operating frequency range and up to the highest audible frequencies. The long throw of up to 35m and smooth horizontal coverage of 100° makes the hd ML-Series a decent and powerful loudspeaker for superior audio environments. The 2“ chassis are due to their small diaphragm weight and almost same size as the human vocal cords the best choice for the reproduction of human voice in the most difficult applications such as airports, train stations, houses of worship, conferencing, and live music.

Harmonic Design® Beamforming loudspeakers give great potential to improve the sound distribution quality in complex architecture and highly reverberant rooms. The goal is to focus the sound only on target surfaces whereas surfaces that cause undesired reflections and create disturbing noise should be shaded. This results in much better speech intelligibility and a premium listening experience for speech and music throughout all rows, allows inconspicuous positioning of the loudspeakers even at less-than-ideal locations and flexible adjustments of the configuration to various demands. 

Smallest Footprint. The ultra compact width of only 86mm makes the hd ML-Series the smallest beamforming loudspeaker available and almost invisible in fixed installations. The elegant designed aluminium enclosure and finely woven steel grille with premium powder-coating-finish integrates the column´s slim, unobtrusive appearance seamless into room architecture and stage areas appealing architects, system integrators, agencies and audiences.

True 1-Way Design. For superb and linear reproduction of a sound event from the fundamental to the highest audible frequencies conventional loudspeakers have to use different types of drivers to reproduce the whole frequency range. The result is incoherence and phase shifts in the mid-range due to different diaphragm masses, varying transient behaviors and decay times of the different sized drivers. The hd column speakers are strictly designed with fullrange loudspeakers and therefore free of interference in the important mid-range because every speaker has the same characteristics. The result is an outstanding sound quality in music and speech, extended dynamic and even horizontal coverage of audience areas. 

Cost Efficient. We offer our beam forming technology in a completely new price vs. performance ratio. This enables utilizing this technology for projects that would have needed beam shaping but would have exceeded the budget. Our in-house developed and manufactured components, algorithms and software guarantees cost efficiency for all our products.

Dante® Spoken here. The Harmonic Design® beamforming loudspeaker are ready for digital audio transmission with Dante audio streams from mixing consoles or control units. Send digital audio signals over a Dante network completely digital through the DSP core and digital amplifiers. A software-controlled fallback input selection switch to the analog secondary input ensures redundancy whenever necessary. If no digital transmission is needed, both analog inputs (primary and secondary) may be used to setup an analog fallback strategy. 

Way-Beyond Spatial Aliasing. The selection of 2“ resp. 3“ fullrange drivers enables the shift of the compulsory occurring spatial aliasing of linear speaker arrays to the highest frequencies where the effect is suppressed by the directivity of the speakers itself. The motivation of downsizing the speaker diameter has risen challenges for our R&D department when it comes to the size of multichannel amplifiers and DSP platform but was an mandatory step to ensure the musicality of the beam-formed speaker array. 

Multichannel DSP Architecture. Based on the huge processing power of our hd MultiDSP a new multichannel DSP architecture suiting the needs of Beamforming algorithms has been derived. Each of the up to 32 output channels as well as user controls features a 384 Taps FIR-Filter and 16x IIR-Filters in double precision. Therefore, the brand new hd BeamDSP utilizes more than 300 million instructions per second to meet real-time criteria and generate enough degrees of freedom to shape the beam as needed. 

Powerful Amplifiers. Each loudspeaker chassis is equipped with a DSP channel and a digital interfaced and microprocessor controlled class-D amplifier. This preserves best SNR for all gain settings and the possibility to surveil the impedance of each chassis and report its status in case of any fault. The output stage is capable of delivering up to 75W into 4Ω loads and ensures premium dynamics and enough headroom for uncompressed audio.
