GT 12A
GT 12 A Polypropylene enclosures
Cabinet Enclosures
Kempton’s GT Series injected moulded polypropylene enclosures feature an
original proprietary cabinet design with smooth and flowing lines that
immediately identifies the GT series appearance from the many Competitors
models that look very much the same. The GT Series enclosures rugged
construction and exterior finish were designed to handle the rigors of the road
when used for portable sound reinforcement applications.
Shape
The Asymmetrical trapezoidal shape design provides a 45° taper angle for
stage monitoring applications as well as for a general Front of House P.A.
system
Pole Mount Sockets & Handles
For speaker stand mounting all GTs are equipped with a 35mm Ø
(13/8”) aluminium pole mount socket. The GT Series models feature
ergonomically placed carrying handles for a balanced “feel” when
handling transporting.
Grilles
Extremely rugged 1.2mm (0.05”) steel grilles protect
the woofer without detracting from its sonic
performance in any way.
Rigging/Fly points & Stacking capabilities
All GT enclosures are provided with multiple M10 fly points to accept standard
M 10 eye-bolts to facilitate safe and easy flying capabilities. The enclosures
are equipped with rubber feet and stacking positions that are moulded into the
cabinet enclosures, allowing stable stacking of 2 cabinet enclosures.
Power Amplifier (GT12A)
The bi-amplification system of the GT12A consists of two independent Class AB
amplifiers, one for the LF woofer and one for the HF compression driver/ horn.
Independent LF & HF Thermal and shortcircuit protection circuits are also
featured. The Crossover circuitry features an active electronic 24dB/oct
Linkwitz-Riley design. The innovative 2-channel on-board mixer (CH A and CH B)
with each one featuring: Preamp Gain, Volume, High Frequency EQ, Low Frequency
EQ controls, XLR/Jack combo inputs. An XLR-M output jack provides mixed signal
output of input channels A and B.
Components
All components were carefully selected and manufactured to Kempton’s
specifications and tolerances and then severely tested for reliability for the
Kempton GT Speaker series. The custom designed Woofers feature high strength
curvilinear cones on steel chassis ferrite frames, high temperature resistant
voice coils to prevent burnout failures and ferrite magnet structures to
produce solid low frequency response. The HF compression drivers provide clean
and clear high frequency output and are coupled to an 80°H x 50°V
custom designed constant directivity horn for precise dispersion.
Crossover Networks
The Heavy Duty Crossover Networks that divide the signal going to the woofer
and compression driver are constructed with oversize coils, high voltage
capacitors and power resistors to provide the best possible sound quality and
minimize signal loss. Independent LF and HF overload protection circuits are
employed to protect the woofers and HF drivers from failures.
Applications
Live Front of House Sound Reinforcement in Clubs, Discos, Piano Bars,
Conference Halls, Houses of Worship, Sports Arenas, Schools, Theatres, Mobile
D.J. use, Foreground Music Reproduction, etc.
