Adam Professional Audio

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 A/B 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 op
