Informazioni sul prodotto "Mackie HR-824"
Released in 1996, the Mackie HR824 High Resolution Studio Monitor redefined what the marketplace looks for in a studio reference monitor. One of the most loved and trusted near-field monitors of all time, the HR824 is found in countless professional studios—thanks to its clarity, broad stereo imaging, ruler-flat response, and extended low-frequency range versus other studio monitors. With such astonishing sound quality, there is little wonder why the HR824 was approved for THX compliance on its initial trial.
Mackie Active technology makes the HR824 possible. Onboard FR (Fast Recovery) amplifiers provide 150 watts to the 8.75” German-engineered MF/LF driver (aka the “woofer”) and 100 watts to the waveguide-loaded HF driver (aka the “tweeter”). The result is a smooth, accurate transition from lows to highs, with an ample 100dB SPL@1 meter output. Frequency response is verifiably flat from 39Hz-20kHz, with a 3dB down point at 37Hz. With extremely even dispersion for a wide "sweet spot" and user-adjustable controls for a variety of acoustic spaces, the HR824 is not only the choice of hundreds of professional studios, they can also be found in the tour buses and home studios of many top recording artists
