The
MacPherson PC12 is a full- bandwidth, multi-application loudspeaker that
excels in both audio quality and application flexibility. The 2-way
design incorporates a sophisticated crossover network, allowing a single
amplifier channel to produce high SPL with minimum frequency and phase
anomalies. The internal components include a 12-inch woofer and a 1-inch
high-frequency compression driver coupled to a constant-directivity
horn. The high-frequency response pattern is 60-degrees horizontal by
50-degrees vertical. The cabinet design allows the PC12 to be stand or
wall mounted, suspended, or simply placed on a flat surface. The PC12
can be used for a wide variety of live and playback sound reinforcement
applications. These include corporate A/V, houses of worship, theater,
and theme parks.
Bandwidth
and clarity—that’s the core of the PC12. The performance is
uniformly impressive, all the way up to its 18kHz top end. The output is
well behaved in both the frequency and phase domains, resulting in
superb vocal and music reproduction. In addition, a major benefit is
that unwanted interactions between loudspeakers and live microphones are
minimized. This greatly increases a system’s gain-before-feedback
performance. The PC12 also exhibits a carefully controlled off-axis
power response. This minimizes unwanted room interactions, resulting in
improved intelligibility and vocal clarity.
The
PC12’s extended low-frequency performance is not typically found in
enclosures of its compact size. Extensive internal bracing is utilized
to limit unwanted vibrations. Internal damping materials were carefully
selected for optimal performance.
An
important PC12 attribute is application flexibility. The cabinet
includes an integral heavy-duty cast aluminum cup. This allows the PC12
to deliver true high-fidelity performance in applications where
stand-mounting is appropriate. Six carefully selected rigging points are
included, allowing suspension at virtually any angle. Two attachment
points are specifically provided for use in "U-bracket"
mounting arrangements. All faces of the enclosure are unobstructed,
allowing a PC12 to be easily located in a soffit, placed on a ledge or
shelf, or recessed into a theater set.
It’s
important to note that the PC12 is designed expressly for use in
single-cabinet point-source applications, including stereo and split
point-source configurations. The PC12’s wide dispersion and
rectangular cabinet geometry is optimized for applications other than
narrow point-source horizontal arrays.
The
PC12’s enclosure is made of hardwood plywood, providing durability as
well as minimal audio resonance. Available standard in black or white,
the low-luster, multilayer paint finish provides a simple, elegant
appearance. The PC12’s small front profile was designed to minimize
obstruction of sight lines. Two integral handles provide assistance
during transportation and set up. Two NL4 connectors are located in a
recessed area of the cabinet, offering both aesthetic and functional
benefits.
