Adam Audio A77H

The New A Series - Built to Reveal!

The new ADAM Audio A Series stands for uncompromisingly precise and transparent sound reproduction. The A Series offers five different models - A4V, A7V, A44H, A77H, and A8H: all designed for a wide range of applications. These mainly include professional and home recording studios, but also broadcasting, installations, and home audio.

The new series features smart and useful innovations, including ADAM Audio’s rotatable HPS Waveguide and DSP-based functions for adapting to individual room acoustics and listening preferences. All settings can be remotely controlled in real time via software. Upgradeable firmware ensures that the A Series studio monitors meet ADAM Audio’s current standards long-term. An extendable warranty of up to five years and customer-oriented support guarantee optimal usability of the studio monitors for many years.

Uniquely Triple

Thanks to the latest ADAM Audio technology, the A77H sets new standards in detail and spatial representation. Two 7-inch woofers, one midrange, and ADAM Audio’s X-ART tweeter deliver the broadest frequency range within the A Series speakers.

The additional midrange ensures precise reproduction of the frequency range especially sensitive to human hearing. The rotatable HPS Waveguide and integrated DSP also allow the A77H to be precisely tailored to individual acoustic requirements.

A Control Remote Software

The DSP-based functions of all A Series monitors can be remotely controlled in real time via Ethernet. This is done using the A Control Remote Software. It is available free of charge as a download for Windows and MacOS to customers who register their A Series monitors in the MyADAM area.

Real-Time Remote Control

The rear of the A Series studio monitors offers many adjustment options but these are usually not directly accessible from the listening position. With the A Control Remote Software, monitoring volume and all equalizer settings can be conveniently controlled remotely from the sweet spot.

Extended Adjustment Options

For some applications, the backplate options may not offer enough selection and precision. A Control allows exact adjustments via six parametric EQs and low- and high-shelf filters. Each filter band can be freely adjusted in gain, frequency, and Q factor to give users complete freedom in optimizing the speaker’s sound in the room.

Integration of Sonarworks Sound ID Reference

Last but not least, A Control also serves as the platform for our collaboration with market leader Sonarworks. Calibration curves generated with "Sound ID Reference" can be imported via A Control and transferred to the DSP of the A Series studio monitors. When this option is activated, calibration takes place directly on the speaker, so no additional VSTs or software applications are needed. This also means that audio playback always occurs with Sonarworks calibration, regardless of the sound source or playback device.

Rotatable HPS Waveguide and X-ART Tweeter

The A Series HPS Waveguide is made from a novel fiberglass polymer material and ensures precisely directed sound radiation from the X-ART tweeter.

What Is a Waveguide?

A "waveguide" is a conically shaped sound guide that (in this case) surrounds the tweeter’s opening. It enables a more homogeneous and better-directed sound radiation. The HPS (High-Frequency Propagation System) waveguides of the A Series are specially developed for our X-ART tweeters and are made from a special fiberglass composite. This material is very low in resonance and helps minimize unwanted vibrations.

Wide Horizontally, Focused Vertically

In the horizontal plane, the waveguide adapts the directional sound radiation of the X-ART tweeter to that of the woofer and midrange in the crossover frequency range. This results in a more even frequency response "off axis," a more stable stereo image, and a larger sweet spot.

In the vertical plane, the waveguide reduces reflections caused by larger objects in the studio such as mixing consoles, desks, or the ceiling. This can prevent comb-filter effects during monitoring.

Optimal Sound in Any Setup

The German handmade X-ART tweeter impresses with precise reproduction of transients and finest sound details. ADAM Audio’s X-ART tweeter is used in all A Series speakers and delivers nuanced sound throughout the product line. The A Series is the first to feature a rotatable HPS waveguide design that allows the tweeter to rotate 90° or 180°. This lets the monitors be used both vertically and horizontally without sacrificing the benefits of the waveguide.

Bass Reflex System, Cabinet & Mounting

The new A Series cabinets clearly follow ADAM Audio’s typical product design, especially that of the AX Series.

Deeper Sound Reproduction, Higher Efficiency

Double-sided, flow-optimized bass reflex ports improve air movement and noticeably reduce any flow noise compared to previous models. Every cubic centimeter counts, so the extremely compact cabinets of the series are trimmed for maximum efficiency in an "industrial" design. The more flattened edges are acoustically advantageous. The significantly more massive baffle prevents cabinet resonances.

Thought of Everything: Mounting

All A Series monitor cabinets are prepared for easy mounting on walls, ceilings, or stands. They feature four M8 threaded holes on the bottom with a depth of 10 mm, arranged in a rectangle measuring 127 mm x 70 mm.

Automated Room Adaptation with Sonarworks

At ADAM Audio, we are especially pleased to offer a solution for automated room adaptation in cooperation with Sonarworks, which takes place directly on the DSP of the A Series studio monitors.

Unfavorable Room Acoustics? No Problem!

The A Series speakers are designed to adapt to changing requirements, preferences, and environments. In many cases, acoustic optimization of the room is not possible due to structural conditions, high costs, or simply because the studio is also used as a living or bedroom. Using the A Control software, precise filter settings can be made to compensate for acoustic shortcomings. Signal processing takes place directly on the speaker’s DSP. Alternatively, calibration curves from SoundID Reference by market leader Sonarworks can be loaded onto the DSP platform after measurement.

Calibrated Sound for All Audio Sources with Less Computing Power

An intensive collaboration between ADAM Audio and Sonarworks has produced the world’s first room correction that uses the studio monitor’s own computing power. This eliminates the need for a corresponding DAW plug-in, simplifying use and reducing the host computer’s workload. The room correction is always available independently of the computer.

Hybrid Amplification

The A Series combines the best of the digital and analog worlds.

Efficient Amplification

The A Series woofers are driven by Class-D amplifiers—optimal for linear performance and minimal distortion. The amplifiers used impress with their high efficiency and low heat generation, leaving room for further improvements and even higher power.

For Best Performance

Class-AB amplifiers power the midrange and tweeter. They are known for especially neutral reproduction of high frequencies. Each amplifier is precisely optimized for its frequency range. The selection and combination of components result from countless measurements and listening sessions in ADAM Audio’s development labs.

Multi-Layer Mineral Woofers [MLM]

State-of-the-art materials and advanced analysis and design methods have led to the development of our new long-throw woofers.

Mineral Fiber

The cone of an A Series woofer consists of several firmly bonded layers of a mineral fiber material. This material is characterized by minimal weight and maximum stiffness. The exact composition is specially adapted for each speaker model. Combined with the newly developed magnet system, each woofer in the A Series delivers exceptionally high levels with minimal distortion—essential for clean and powerful bass reproduction.

The Development Process

Before production readiness, the A Series woofers underwent numerous tests and prototypes. Using Klippel’s simulation tools, ADAM Audio’s R&D team developed drivers that operate with minimal distortion even at maximum sound pressure.

Midrange

The A Series midrange ensures precise reproduction of the frequency range especially sensitive to human hearing.

Committed to Precision

The A Series midrange is based on the highly regarded DCH midrange from the S Series and delivers exceptionally clean reproduction in the critical midrange. It also relieves the woofer from reproducing mid frequencies. Both the A77H and A8H are designed as 3-way systems and equipped with the A Series midrange.

Power Like a Piston Radiator

The cone of the A Series midrange consists of the same multi-layer mineral fibers as the woofers. The cone is laminated and cut from several layers in a special process. The voice coil is suspended in a homogeneous magnetic field with a large, linear working range to avoid any sound modulation. Distortions caused by "breaking" the cone lie far outside the midrange’s working range.

Voicings

"Voicings" refers to preset sound profiles. On all A Series models, two different voicings can be selected on the rear of the studio monitors via a switch: "UNR" and "Pure." Room adaptation is independent of the selected voicing. When using the A Control software, additional functions are available via the "Ext" option, such as even more detailed adjustments or Sonarworks calibration.

Uniform Natural Response

"UNR" or "Uniform Natural Response" delivers a minimally colored yet very natural-sounding frequency response. It is based on some of ADAM Audio’s most popular monitors, especially the AX Series. The pleasant and lively sound enables long production and songwriting sessions without fatigue. This setting is also ideal for music enjoyment.

PURE

"Pure" offers a maximally neutral and linear frequency response. This voicing is the first choice whenever the highest fidelity is required—typically for mixing and mastering.

Room Adaptation

For optimal adaptation to the acoustic environment, each A Series speaker has a 4-band equalizer on the rear with parameters "Bass," "Desk," "Presence," and "Treble." Each frequency range can be adjusted in predefined steps, offering flexibility to compensate typical acoustic problems that occur in room speaker placement.

Bass: Overlap Caused by Walls

If a speaker is placed close to a (sound) hard wall, low frequencies overlap, causing bass to be overrepresented. The "Bass" adjustment compensates for this so the speaker does not sound bass-heavy. Possible settings are +2, 0, -2, and -4 dB.

Desk: Reflections from Desk or Console

If a speaker is placed on or near a desk surface, the listening position will predictably experience an overrepresentation in the low-midrange caused by early reflections. The "Desk" control compensates for this effect, preventing the speaker from sounding boomy. Settings are 0, -2, and -4 dB.

Presence: Compensation for Room Acoustics

Under certain circumstances, the midrange can sound harsh or rough due to room acoustics or equipment used. The "Presence" control tames this harshness and restores the speaker’s natural sound. Available settings are +1, 0, and -1 dB.

Treble: Compensation for High-Frequency Absorption

In rooms with too much or too little absorption of high frequencies, the sound can seem dull or harsh. The "Treble" adjustment restores a natural balance. Values are +1.5, 0, and -1.5 dB.

Digital Signal Processing

Thanks to powerful DSP technology, all A Series monitors offer significantly improved and more extensive options for acoustic tuning compared to purely analog speakers.

Consistency and Longevity

A key advantage of DSP-based speakers over analog systems is their consistency and predictability. Since signal processing occurs digitally, crossovers, filters, and equalizations do not age as analog components do. Signal conversion is done via high-quality AD converters carefully selected by ADAM Audio to achieve excellent performance.

Always Up to Date

The powerful DSP of the A Series enables many functions, from remote control and room adaptation to selecting different voicings. All DSP-based features can be updated via Ethernet connection, including filter types, voicings, and new functions.
