operate in distributed or low-impedance mode)

AD-C1200

The AD-C1200 is designed for music
playback, public address and distributed
audio in applications that require high
output from a ceiling mounted loudspeaker.
The AcousticDesign™ Series of installation
loudspeakers has been designed for trouble
free operation and versatility. Utilizing custom
designed transducers and crossover networks,
in combination with an acoustically optimized
enclosure (AD-C1200BB), the AD -C1200
continues the AD Series philosophy to bring
the same versatility and reliability to high­ceiling applications.

Each AD-C1200 includes the coaxial
transducers, a transformer and a crossover
network factory mounted on a steel baffle.
The baffle is designed to mount to the
QSC enclosure (AD-C1200BB) or to any
~2.5 ft 3 enclosure using industry standard
transducer mounting dimensions. A square
grille (AD-C1200SG) is available to finish
the installation.

The 12" woofer is made with a treated paper
cone on a steel frame. In the optimized
enclosure the usable low frequency of
the system extends to 37 Hz. The 1.75"
compression driver fires through the center
of the woofer and is acoustically mated
to the woofer for a smooth transition at
crossover. The system achieves 85 degree
axisymmetric coverage.

High-current, low tolerance network
components provide smooth full-range,
passive performance. The included 70V/100V
custom designed transformer is optimized
for low line loss as well as accurate and
transparent acoustic performance.

The AD-C1200 loudspeaker system
measures 93 dB sensitivity (1W/1m) and at
full continuous power is capable of producing
118dB SPL (1W/1m) output.
