The hd AudioScreenSys is an audiophile all-in-one stereo sound reinforcement solution with integrated subwoofers and 4+2In DSP amplifier for larger screens, LED walls and projection surfaces in mobile or permanently installed multi-media applications. The hd AudioScreenSys consists of an active column speaker and a passive column speaker. Each column speaker is equipped with a 3.5″+1″ dual concentric mid/high unit with two additional 3″ woofers in D’Appolito arrangement and a subwoofer array of five 3.5″ high-excursion woofers. This arrangement creates a directional vertical radiation in the low-mid range and ensures a longer range.

The active column speaker contains the entire amplifier electronics of the overall left/right system. Our 4+2In/4Out High-End hd ProDSP platform with highly efficient 4-channel Class-D amplifiers with a total of 300 W RMS ensures maximum operational reliability, unique headroom and the best possible audio quality for presentations, video conferences and music playback at all times.

The input stage consists of a stereo line-in for the permanent connection of the TV or media sound and two microphone line-ins for the connection of radio microphones, headsets, clip-on microphones or any line signals. A volume control for both microphone systems is located on the recessed connection panel. Four sound presets and four microphone presets, suitable for the most common microphone types and models, can be called up via buttons on the connection panel. A permanently active dynamics processor with expander, compressor and gate function for the microphone channels ensures ideal microphone operation without additional hardware. BYOD prepared thanks to the optionally available wireless audio interface. The hd AudioScreenSys is the optimal sound reinforcement solution in the course of the digitization of the working world. The state-of-the-art, reliable and easy-to-use all-in-one complete solution can be used cost-effectively for the audio-technical equipment of media steles, larger conference rooms, museums, educational institutions or hotels and external DSPs and matrix systems become superfluous.

The shapely aluminum housing can be manufactured to match the height of the screen or presentation area if required. The possibility of special painting in all RAL CLASSIC colors ensures seamless integration into the architecture. The integrated, continuous 13 mm T-slot on the back is used to accommodate customer-specific wall brackets. In the case of direct wall mounting, the column loudspeakers can be mounted flush to the wall with the optionally available L-angle wall bracket.

Finally understand each other

Sharing thoughts, visions and feelings through communication is an essential part of human interaction. In the professional environment, this is happening more and more with the help of virtual media, e.g. video conferences and online meetings – without personal contact.

Important aspects such as the dynamics, voice color, articulation, expression and emotions of the counterpart go far beyond pure speech intelligibility. For the experience of an authentic meeting, the full information content of language must not remain on the transmission path. Otherwise the concentration and productivity of the participants will suffer. Misunderstandings are inevitable.

The uncompromising use of the latest pro audio technology meets the highest audiophile requirements and combines complex multimedia components in one device that anyone can operate.

With the hd AudioScreenSys you can create a pleasant collaboration environment for a respectful and appreciative encounter between colleagues and business partners without any technical effort.

Premium audio for speeches and lectures

Our presentation solutions are designed for a wide variety of requirements and room scenarios. They also offer a high degree of flexibility and simplicity. After all, you should be able to concentrate on the essentials: on what you want to say. As our solutions are optimized for speech applications, they offer the highest level of speech intelligibility. And you can rely on the reliability of our components even in continuous use.

Dual concentric loudspeakers in D`Appolito design and integrated subwoofer array

Our dual concentric speaker ensures that you can understand every word and enjoy the full spectrum of sound wherever you are. The D’Appolito arrangement of these special loudspeakers together with two deep tone extensions increases the range and directivity of the sound system and thus reaches every listener.

The integrated subwoofer array gives your videos goose bumps in the lowest octave and delivers a crisp, round bass with media sound recordings without booming. Pure concert feeling! But do not worry: thanks to the different signal processing for media sound and speech, your video conferences and presentations remain crystal clear with a well-balanced tone range.

Reliable and Audiophile.

A multi-channel digital signal processor based on our hd ProDSP platform is the heart of the system. It manages all inputs and outputs, uses the most modern algorithms for sound optimization and is equipped with highly efficient power amplifiers at the same time. As soon as it has been processed and digitized, the audio signal is forwarded to the intelligent amplifier section in the highest audiophile quality without any loss.

As with all Harmonic Design speaker systems, we use FIR filter technology to achieve a perfect sound experience. And when it gets louder, intelligent protective circuits ensure maximum operational safety – 24/7!
