Audio professionals in need of a high-quality midfield monitor will be impressed with the Adam Professional Audio A77H, a professional, dual 7" 3-way studio monitor speaker that delivers rich, spacious, and enveloping sound.

A 250W RMS Class-D amplifier powers the dual 7" Multilayer Mineral (MLM) woofers, while 70W + 20W Class-AB amplifiers drive the MLM midrange driver and X-ART tweeter with HPS waveguide to provide an ultrawide frequency range. The midrange driver helps produce clear sound in the most sensitive range of human hearing. The rotatable High-Frequency Propagation System (HPS) waveguide technology and onboard DSP allow you to finely tune the speakers to your precise requirements.

Rotatable HPS Waveguide and X-ART Tweeter
  • ADAM Audio HPS (high-frequency propagation system) waveguide technology enables tweeters to disperse sound with controlled consistency, broad in the horizontal axis but tightly focused on the vertical plane. The A Series monitor introduces a rotatable HPS waveguide design. You can shift A Series tweeters in 90-degree steps to continue to benefit from HPS waveguide technology, whether you position the speakers horizontally or vertically.
  • The A Series HPS Waveguide is made from a new glass-fiber polymer compound that helps create a clear sound, free of unwanted resonance. The ADAM Audio X-ART tweeter is at the heart of the rotatable HPS waveguide. Handmade in Germany, the X-ART tweeter provides a precise transient response and reproduces the finest sonic details. This X-ART tweeter is used in every A Series speaker, providing a detailed and consistent sound across the product line. 
Multilayer Mineral Woofer
A Series woofers are constructed with a unique blend of mineral stone fibers that have been baked together to create a lightweight but highly stable material. The mineral composition, layering, and geometry of each cone is specific to the driver used in each model. By combining this material with a new magnet system, A Series woofers produce high output with low distortion, delivering a clean low end.
Midrange Driver
Adapted from the ADAM Audio DCH midrange driver used by the S Series speakers, the A Series midrange driver delivers a clean sound in a critical part of the frequency range, where humans are especially sensitive to coloration of sound. Using a dedicated driver for the midrange further helps clarify lows and highs by eliminating the need for woofers to reproduce midrange frequencies, and so also reduces distortion.
Hybrid Amplification
  • The A Series combines the best of both digital and analog worlds. The woofers are driven by Class-D amplifiers that help produce linear performance while reducing distortion. These amplifiers were chosen specifically for their power and efficiency, in terms of both energy consumption and sound reproduction. Low thermal dissipation allows for a smaller heat sink, which facilitates additional investment in the exceptional power and performance of the A Series.
  • Tweeters and midrange drivers are powered by Class-AB amplifiers, which offer smooth, natural reproduction of high frequencies. Each amplifier is optimized for its working range, resulting in a fine-tuned, properly aligned speaker. To reach this point, ADAM Audio carried out extensive measurements and listening sessions, trialing countless amplifiers and amplifier components.
DSP-Based Electronics
The A Series capitalizes on the transformative power of DSP-based electronics to provide greater tuning precision and better predictability than analog-only speakers. With firmware that can be updated through an Ethernet connection, over time you can expect to integrate the latest DSP-based capabilities from ADAM Audio, including new filter types and features, plus alternative voicings.
Room Adaptation
On the back panel of A Series speakers, you will find four bands of room-adaptation equalization: Bass, Desk, Presence, and Treble. Each band is adjustable in predefined steps, offering more than 100 tuning options to help compensate for the typical acoustic problems that arise from speaker placement.
Voicings
  • A Voicing is a predefined sound profile of the A Series monitors. On the back panel, you will find two different selections, UNR and Pure. Here you will also find the Ext option, which is dedicated to the extended functionality that comes with A Control via the Ethernet connection. 
  • UNR or Uniform Natural Response is a dynamic natural-sounding response curve of ADAM Audio’s own design, which stems from a variety of iconic ADAM Audio legacy products including the preceding AX Series. It lends itself to production, composition, and songwriting, as its engaging and present sound can give you more room for creativity and flow. It is also a great option whenever you want to use your speakers simply to enjoy some good music. 
  • Pure is a highly accurate and neutral sounding option. This is the flat setting, ideal for mixing and mastering, where you must be aware of all the details and rely on an honest representation from your speakers. 
  • The Ext option is dedicated to the extended functionality that comes with A Control (real-time remote control) via the Ethernet connection. Using A Control’s six-band EQ, a custom voicing and be created and pushed to the monitor. 
A Control (Real-Time Remote Control)
  • The DSP-based functionality of all A Series monitors can be controlled remotely and in real time over Ethernet using the free to download A Control software. A Control is available to download for Windows and MacOS in the MyADAM area of www.adam-audio.com for customers who have registered their A Series monitors.
  • Once downloaded and installed, you can control multiple speakers at once, precisely adjusting equalization and delay settings from various listening positions in your studio space. While you work, you can remotely control monitor levels if you’re far from a fader or physical interface. Remote-control capabilities are particularly useful in multipurpose rooms, allowing you to make sure that voicing, EQ, and other settings are all exactly how you want them. 
Room Correction and Sonarworks Integration
A Series speakers are designed to be adaptable to changing requirements, preferences, and environments. Using the A Control software, you can push advanced filters directly to an embedded platform onboard the monitors to help compensate for imperfect room acoustics. This embedded platform supports filters from the industry-leading third-party, Sonarworks. Using Sonarworks software and a measurement mic, you can calibrate your speakers for a new room or per shifting taste.
Bass-Reflex System, Cabinets, and Mounting
The new A Series cabinets build on the heritage of ADAM Audio and the AX Series. In an evolutionary design, A Series cabinets have deeper beveling to further reduce diffraction. Thicker baffle walls strengthen the cabinets and reduce internal vibrations, while a flared port design optimizes airflow and reduces port noise. All A Series speakers include an underside mounting interface, giving you the flexibility to mount them wherever you need them.
