The QSC AcousticDesign™ AD-S802T is a
columnar array line consisting of eight
weather treated 2.75" transducers.
Columnar loudspeakers are ideally suited for
a wide variety of acoustically difficult
applications where speech intelligibilty is a
primary concern.
The AcousticDesign Series offers integrators
a premium quality installed sound solution
where performance, consistent coverage,
and aesthetics are paramount. Specifically
designed to maintain a consistent tonal
characteristic across the entire family in
ceiling, surface, and pendant applications,
the AcousticDesign Series allows integrators
seamless transitions within blended
installations.
With rugged powder coated aluminum
construction, stainless steel hardware, and
sealed input panel cover, the AD-S802T is
designed for indoor or outdoor use,
exceeding IEC60529 IP-54 ratings for dust
and splash resistance.
A carefully crafted PTT (Progressive Taper
Topology™) network is utilized to create a
passive curvature of the array line which
greatly reduces side lobing, often
problematic of straight array lines, resulting
in precise and consistent directivity control.
The accurate frequency response of the
AD-S802T is maintained even in 70/100V
applications by use of a low-loss, lowsaturation transformer with selectable taps,
including a bypass for low impedance
application, using a rotary selector located
behind the sealed input cover plate.
The input cover plate comes with an
attached wire sealing gland nut for direct
cable attachments onto a locking 4-pole
Euro-style connector for added security of
the wire terminations. The gland nut may
be removed in provision of alternative
conduit or flex tubing landed requirements.
Installers will appreciate the quick-hang
pan/tilt mounting bracket supplied the
AD-S802T. This feature greatly reduces the
amount live-load time during high reach
installation, allowing the installer to work
faster, safer, and smarter. The mount
includes a zero pan locking screw in
consideration of wind load conditions. The
mount may be attached to several landing
positions on the enclosure to provide a
close to wall appearance. When tilt is not
required, the tilt section of the mount may
be removed to bring the enclosure even
closer to the wall. A shoulder eyebolt is
supplied to provide a safety tether anchor
point.
Intrinsic Correction™ voicings that optimize
performance and speed the install process
are easily deployed via the Q-SYS Platform
including CXD-Q Series amplifiers, as part
of a complete QSC systems solution.
The AD-S802T is available in QSC standard
black (RAL 9011) or white (RAL 9010) and
may be painted to match any decor.
