## Long description

The Adam Audio A77H 500W active studio monitors combine a wide frequency response and high output level in a compact enclosure. The system features ADAM Audio's X-ART tweeter, a dedicated midrange driver and two 7" woofers to cover the most critical parts of the audible spectrum. With a stated frequency range from 34 to 45,000 Hz and an RMS rated power of 500 W, the A77H is designed to deliver detailed highs, precise midrange and controlled low end from a black MDF cabinet with dimensions 531 mm (W) x 350 mm (D) x 236 mm (H).
Advantages
The multi-driver configuration—X-ART tweeter, midrange driver and dual 7" woofers—provides an extended and balanced frequency response, improving clarity across vocals and instruments. Onboard DSP and a rotatable HPS waveguide allow room and position-specific tuning. The 500 W RMS power rating and a measured noise level of 118 dB support high SPL playback while maintaining headroom for dynamic material. The black MDF housing offers a durable, acoustically stable enclosure suitable for professional studio environments.

How to use
Place the A77H monitors on stable stands or integrated furniture at ear height for critical listening and allow a short break-in period after installation. Use the onboard DSP and the rotatable HPS waveguide to adjust dispersion and tonal balance according to your room layout and listening position. Connect the monitors to a compatible AC supply (100–240 V, 50 Hz) and to your audio interface or monitor controller using appropriate balanced connections as recommended by your system documentation. Start with moderate output levels and increase to the desired monitoring level while checking for clipping or unwanted distortion.
Usage recommendations
Position the speakers symmetrically in the room and perform a brief acoustic check to set DSP options and waveguide orientation. Allow a stabilization period after powering on before critical listening, and use calibration tools or room correction software when precise tonal accuracy is required.
