The Cobra-2 system is designed
to provide high-quality sound
reinforcement for events in small
to medium-sized marquees or
halls covering distances of up to
40 meters and areas up to 1,000
square meters.
The system produces a maximum
sound pressure level of 137 dB L
and 137 dB R in the mid / high fre-
quency range and up to 141 dB in
the bass. In its basic confi guration,
the Cobra-2 system comprises four
Cobra-Top mid / high cabinets,
four Cobra-Sub subwoofers, a
ready-wired and pre-programmed
system amp rack and the requisite
4-pin loudspeaker system cables
along with a set of wedges (two
2.5° wedges that can be used either
side) that make it possible to aim
the Cobra-Top cabinet to suit the
Cobra-2
COMPACT LINE-ARRAY ACTIVE 2-WAY SYSTEM
area to be covered. The system
amp racks are easily capable of
driving up to six Cobra-Top and/
or six Cobra-Sub cabinets. If it is
desired to expand the system, the
amp rack is capable of accommo-
dating additional power amplifiers
(bass extension, front- / side-fills
or monitors) as well as supplying
them with the requisite power via
the AC connector panel.
The maximum Cobra-2 confi guration
that makes sense comprises two
Cobra-2 systems per side (four
Cobra-Tops and four to six Cobra-
Subs per side). Since, however,
doubling the number of stacked or
flown Cobra-Top cabinets results
in a halving of the vertical co-
verage angle, particular attention
must be paid in such cases to the
aiming of the cabinets in the wing
or stack. A single Cobra-Top has
a (horizontal x vertical) coverage
pattern of 120° x 30°; this is reduced
to 120° x 15° if a second, and to
120° x 7.5° if a third, Cobra-Top is
added to the stack. When ground-
stacked, the Cobra-Top cabinets
can be aimed with precision at
the area to be covered through
the use of the 2.5° wedges that
are supplied as standard. If added
pressure or projection is needed in
the bass, whether due to the style
of music or to the acoustics of the
venue, Cobra-2 systems can also
be armed with Cobra-PWH bass
horns.
With two PWH cabinets (or three
Cobra-Subs) superposed, you obtain
a plinth the ideal height (180 cm)
for ground-stacking the Cobra-Top
cabinets on.
