ADAM A77H

The A77H is a true midfield monitor in a 3-way design and is therefore the consistent further development of the A77X. Thanks to the latest ADAM audio technology, it also sets new standards in terms of detail and spatial representation. Two 7-inch woofers, a midrange driver and ADAM Audio's X-ART tweeter provide the widest frequency range within the A-Series speakers. The additional midrange driver ensures precise reproduction of the mid-frequency range, which is particularly sensitive to the human ear. The rotatable HPS waveguide and the integrated DSP also enable the A77H to be precisely adapted to individual acoustic requirements. Rotatable HPS waveguide and X-ART tweeter The ADAM Audio HPS (High-Frequency Propagation System) waveguide ensures precisely directed sound guidance with a wide beam angle horizontally and narrow focusing vertically. All A-Series models use the rotatable HPS waveguide design, which allows the tweeter to be rotated 90 degrees. This means that the monitor can be used both vertically and horizontally - without having to forego the advantages of the waveguide. The A-Series HPS waveguide is made from a new type of fiberglass polymer material. Its high density minimizes unwanted resonances and supports a clear sound. The ADAM Audio X-ART tweeter is located in the center of the rotating HPS waveguide. Handcrafted in Germany, this tweeter guarantees maximum impulse fidelity and richness of detail. All A-series models are equipped with this X-ART tweeter. Multi-layer mineral woofer The membrane of an A-series woofer consists of several, firmly connected layers of a mineral fiber material. This material is characterized by minimal weight and maximum rigidity. The exact nature was adapted specifically for each loudspeaker model. In combination with the newly developed magnet system, each woofer from the A series delivers exceptionally high levels with minimal distortion - essential for clean and powerful bass reproduction. Midrange The midrange driver of the A series is based on the highly regarded DHC midrange driver of the S series - ADAM Audio's high-end monitors. In the medium frequency range, the hearing reacts particularly sensitively to sound coloring. This is exactly where the new midrange driver ensures exceptionally clean reproduction. In addition, it releases the woofer from reproducing medium frequencies. Both the A77H and A8H are designed as 3-way systems and are equipped with the A-Series center driver. Hybrid amplification The A series combines the best of the digital and analog worlds: The woofers are driven by Class D power amplifiers - optimal for linear performance and minimal distortion. The power amplifiers used impress with their high efficiency, which is accompanied by low heat generation. This creates potential for further improvements and even higher performance. Class AB power amplifiers are used for tweeters and midrange drivers. They are known for their particularly neutral reproduction of high frequencies. Each power amplifier is optimized precisely for its frequency range. The selection and composition of the individual components are the result of countless measurements and listening sessions in the ADAM Audio development laboratories. DSP-based electronics Thanks to powerful DSP technology, all A-series monitors offer significantly improved and more extensive fine-tuning options compared to purely analog speakers. The firmware can be updated at any time via an Ethernet connection. This means that A-Series monitors always feature ADAM Audio’s latest DSP features – such as new filter types and “voicings”. Adaptation to the room acoustics For optimal adaptation to the acoustic environment, there is a 4-band equalizer on the back of every A series loudspeaker with the parameters “Bass”, “Desk”, “Presence” and “Treble”. Over 100 variants for fine adjustment enable adaptation to the most demanding listening environments in seconds.
