COBRA-4 SYSTEM
Cobra-4
COMPACT LINE-ARRAY ACTIVE 4-WAY SYSTEM
The active 4-way Cobra-4
System in its standard confi guration
is designed for throws of up to 80
meters in medium-sized marquees,
halls and open-air venues.
It is capable of generating at a
FOH position 30 meters distant a
sound pressure level of 110 dB in
the mid-high frequency range and
120 dB in the bass – exactly what
the typical Top 40 band requires.
Through the use of two Cobra-4
Tops and one Cobra-4 Far, optimum
line-array performance can
be obtained even from a typical
116
stacked configuration without
time-consuming adjustments. For
large distances, the top position in
the stack is reserved for a Cobra-4
Far unit, which has a coverage
pattern of 90° (horizontally) and
5° (vertically) in the high frequency
range.
For the low frequency and midrange,
the same components are used
as in the Cobra-4 Top, providing
the ideal extension for the low-
and midrange line array. In all,
eight Cobra-PWH bass horns are
needed to generate the pressure
and projection in the bass region
EASE FOCUS
required by typical Top 40 bands.
Depending upon the geometry of
the room, these can be stacked
or arranged as a horizontal bass
array.
The Cobra-4 System can be driven
either by ready-wired and pre-programmed
amp racks, comprising
a controller, power amplifiers and
AF- and AC connector panels, or by
individual (user-configured) racks.
When PowerH power amplifiers are
used in conjunction with RCM-26
modules, advantage can be taken
of FIR-linearized presets.
A very wide variety of configurations can be mechanically simulated and
checked acoustically as early as the planning stage using the software
application EASE Focus. After download of EASE Focus from DYNACORD
web site, you can consult all the electrical and mechanical specifications of
the Cobra cabinets and also calculate automatically the optimal suspension
points of the grid for different loads and rigging angles.
OPTIMIZED FACTORY PRESETS INCLUDING FIR-TUNE
LINEARIZATION ARE AVAILABLE FOR DSP 600,
P 64 AND PowerH AMPLIFIERS WITH RCM-26
