Part of Adam's professional studio-grade A Series, the Adam A77H is a three-way monitor designed for midfield monitoring in recording studios. As the successor to the successful Adam A77X, it expands on that model's 2.5-way configuration. Sonically, the speaker will satisfy even the highest standards, delivering exceptional detail and spatial imaging across a frequency range of 34Hz to 45kHz. Bass reproduction is handled by two 7" woofers, complemented not only by a tweeter but, unlike its predecessor, also by a 3.5" midrange driver. The H in the model name stands for horizontal, as it's primarily designed for this position – but in fact its impressive width of over 53cm is unlikely to be an issue, as the rotatable waveguide with HPS technology allows the monitor to be positioned either horizontally or vertically. In addition, the integrated DSP enables users to adapt the A77H's output to the acoustic characteristics of the room.
The Adam Audio A77H's bass diaphragms have a multi-layered construction made from a lightweight mineral composite that offers high rigidity at an extremely low weight. The speaker's bass reflex system adds even more bottom end, with front-facing ports that blend seamlessly into the design. The A77H's tweeter is a hand-crafted X-ART unit made from a ribbon folded into a lamellar shape, and thus capable of exceptionally fast sound transmission. A multicolour LED indicating the speaker's status will assist producers when they're adjusting the DSP remotely using Adam's proprietary A Control software suite (the A77H is of course equipped with the RJ45 Ethernet port needed for connection to the computer running the software). The monitor accepts signals in both professional and consumer formats through XLR and RCA connections and delivers them with a powerful amplification of 270W RMS, achieving a maximum level of 106dB SPL.
The Adam A77H is a high-quality monitoring solution for professional studios, as well as for project studios with particularly demanding sonic requirements. Adapting the sound of an A77H unit to the acoustics of a control room is possible enitirely without external tools: The speaker's automated room adjustment function is handled by its integrated DSP and is based on algorithms from Sonarworks, a company renowned for its calibration software for speakers and headphones. This makes the monitor suitable even for control rooms whose geometry or equipment isn't necessarily optimised for monitoring purposes. To position the speaker in the studio (for which purpose four M8 mounting threads are provided), a stand or shelf capable of supporting its weight of just over 17kg (including its vinyl-coated MDF chassis and internal components) is required. Adam Audio is of course aware that monitors in this price range represent an investment, which is why they offer an extended five-year warranty on every unit.
ADAM Audio was founded in Berlin in March 1999 and has since been involved in the development, manufacture, and distribution of speakers specifically aimed at the professional audio industry. The company was founded following the development of the X-ART tweeter, itself based on the Air Motion Transformer created by Oscar Heil in the 1960s. Advanced Dynamic Audio Monitors (ADAM) has rapidly set new standards in the world of studio monitors. The company employs over 50 people in its Berlin factory, is distributed in over 75 countries, and has sales offices in both the USA (Nashville) and the UK. The list of renowned studios using ADAM monitors is long and still growing. ADAM Audio has been part of the Focusrite Group since 2019.
In challenging listening environments, the Adam A77H can be conveniently adapted thanks to its integrated DSP's room correction function. Furthermore, Adam's A Control software package can be used to program filters, which can then be stored internally in the speaker's memory. Manual adjustment options for adapting the A77H to a space include six parametric equalisers on the rear panel, as well as level control and delay settings. For those who prefer not to make individual adjustments manually, the speaker's performance can be measured using the Sonarworks SoundID Reference software, creating curves which can then be applied to the speaker's DSP unit. In terms of power consumption, it should be noted that a single monitor can draw up to 220W.
