AD-S282H
AcousticDesign™ Loudspeaker
Features
• Contemporary style, weather resistant enclosure and components—
ideal for a wide range of applications
• Dual 8", 2-way system—in a lightweight, multipurpose enclosure featuring
a heavy duty, powder coated aluminum grill
• Versatile mounting options—the included yoke mount bracket can be used
for mounting and aiming the system in vertical or horizontal orientations.
Provision for optional Omnimount™ bracket is built in
• Advanced Directivity™ rotatable waveguide—(90º x 60°) enables the
loudspeaker to deliver accurately focused sound, regardless of the enclosure’s
mounted orientation
• Low-impedance and transformer versions—Standard 8 ohm system is
selectable for passive bi-amp operation while the AD-S282HT transformer
version provides taps for both 70 and100 volt distributed system use
The QSC AcousticDesign
AD-S282H is a full range, surface
mount loudspeaker with a sleek,
contemporary styling that fits
perfectly into multiple surroundings
and applications including hotels,
restaurants, convention facilities,
and multimedia environments.
The speaker incorporates the
Advanced Directivity rotatable
waveguide. Available in black or
white, these weather resistant
enclosures can be painted to
match any specific décor.
The AD-S282H is a 2-way system
housed in a ported enclosure
made from injection molded, highimpact polystyrene. This enclosure
incorporates two 8" weather
resistant, LF transducers with heavyduty double roll cloth surrounds.
These high output versions employ
a 1" exit compression HF driver.
The HF driver is coupled with
QSC’s unique Advanced Directivity
rotatable waveguide—enabling the
loudspeaker to deliver accurately
focused sound, regardless of its
mounted orientation.
