The hd AudioBar is an audiophile all-in-one sound solution for conference rooms, training rooms and multi-media applications with a configurable audio matrix with digital mixer functions and presenter function. Thanks to the integrated LinearPhase FIR filter technology, a linear transmission behavior with excellent speech intelligibility is also made possible for video conferences or presentations. The FIR filter technology enables frequency- and phase-independent sound optimization. This means that feedback and a distorted sound are a thing of the past. The stereo-arranged dual-concentric mid/high frequency unit achieves a wide horizontal radiation and allows a breathtaking effect reproduction and depth graduation of the sound image. The integrated subwoofer array delivers a crisp, round bass without booming.

The input stage consists of a stereo line-in with auto-detect function for TV or media sound and two microphone line-in for connecting wireless 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 dynamics processor with expander, compressor and gate function for the microphone channels and a freely configurable EQ section for room and microphone equalization allow the best adjustment of the system without additional hardware. Bring your own device prepared.

The hd AudioBar is the optimal solution in the course of the digitization of the working world. The ultra-modern, reliable and easy-to-use all-in-one complete solution hd AudioBar can be used cost-effectively for the audio-technical equipment of huddle rooms, media steles, conference rooms, museums, educational institutions or hotel suites and external DSPs and matrix systems are superfluous.

With the help of mounting brackets, the hd AudioBar can easily be attached to the VESA brackets of the screen. Alternatively, all common wall brackets can be attached to the continuous T-slot on the back. Thanks to flexible manufacturing processes, the hd AudioBar has been able to be precisely adapted to the screen dimensions and surroundings for years – without long delivery times.
A recessed connection field with three 3.5mm jack input sockets with auto-detect function, 4-pin Power-Din mains socket for external 24V power supply, pairing button and two preset buttons are located on the back of the housing.

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 AudioBar and VideoBaryou can create a pleasant collaboration environment for a respectful and appreciative encounter between colleagues and business partners without any technical effort.


At Harmonic Design, no compromises are made when it comes to sound reproduction.

As an owner-managed, Swabian company, we live our passion for high-quality loudspeaker and amplifier technology every day and work with great attention to detail on innovative solutions for sound reinforcement tasks, so that our Pro-Audio DNA is in every product. We have remained true to ourselves for 40 years.

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.

Stereo speakers with wide radiation and an integrated subwoofer array

Our dual-concentric loudspeakers ensure that you can understand every word and enjoy the full spectrum of sound. The symmetrical radiation of these special loudspeakers makes the positioning of the hd AudioBar and hd VideoBar unproblematic and can be installed under or above the presentation area and still reach 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!
