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
