World’s First

Compact Line-Array System

Pat. Pent.

• Groundstack or flying

• High SPL capability

• Line-Array Performance

• Easy Handling

Line arrays have now become the preferred solution in the professional sound reinfor­cement business. Superior directivity over a larger frequency range, more consistent
SPL projection across greater distances, and lower distortion through out the dynamic
range are a few of the acoustical advantages gained over typical, horizontally arrayed
speaker systems. As a result, line array systems are significantly well suited for provi­ding a more consistent, higher level of fidelity amidst a greater majority of typical sound
reinforcement applications.

Conventional line arrays today are large, heavy , expensive, and extremely costly to out­fit and operate. Thus, they are typically constrained to a smaller range of applications,
where a higher standard of audio quality takes precedent over cost. Despite their
advantage in sound quality, conventional line arrays are seldom selected for all but the
largest, most costly considerable applications.

Enter the DYNACORD COBRA compact line array systems, COBRA 2 and COBRA 4.
Simply stated, the DYNACORD COBRA systems harness the greatest acoustical
advantages of line array philosophy to deliver an exceptional level of fidelity, and use­ability. All this designed in a remarkably compact, cost effective, easy to handle pack­age that has yet to be equaled, less even approached.

The extremely wide horizontal and shallow vertical directivity of the DYNACORD
COBRA compact line array systems provide coverage to large audience areas
unscathed by the typical destructive, acoustical interference that is unavoidable
with typical, horizontally arrayed speaker systems. This level of controlled direc­tivity offers many advantages. The lack of unwanted energy from the sides and
rear of the array allows for easier placement, lower stage noise, and astounding
levels of gain before feedback. The loss of energy towards unwanted reflective
surfaces is avoided, eliminating most interference from the surrounding envi­ronment. Additionally, it provides a greater majority of output focused in the
useable plane, resulting in higher efficiency.

Every aspect of a COBRA system has been designed to ensure maximum ease of handling,
reliability, and audio fidelity.

All Cobra system speaker cabinets are equipped with heavy-duty castors for easy transport,
a latching front cover for protection in transit, and specific component thermal protection
known as VOICE COIL TRACKING PROTECTION. This circuit monitors the thermal behavi­or of each specific component and allows for accurate protection with virtually no acoustic
interference.

Each COBRA system includes prewired, and programmed amplifier racks. Each rack con­tains a DYNACORD DSP-244, two DYNACORD L-2400 Precision Series amplifiers and a
connector panel for input and output signal. The DSP-244 is optimized for each specific
COBRA system to ensure proper phase response, time alignment, crossover, system equa­lization.

COBRA-2 SYSTEM

The COBRA - 2 System is designed to provide high quality sound reinfor­cement for events in small to medium sized applications covering distances
up to 120 ft. The COBRA -2 system basic configuration produces a maxi­mum SPL of 137 dB L+ 137 dB R in the mid-high frequency range and 141
dB in the bass.

In it's basic configuration, the COBRA - 2 system consists of 4 COBRA TOP
mid-high enclosures, 4 COBRA SUB subwoofers, a pre-wired CSR 12
amplifier rack with necessary speaker cables and a pair of 2.5° tilt boards
that can be arranged up or down, under the COBRA TOPs for optimal ver­tical coverage and aiming.

If required, up to 6 COBRATOPs and 6 COBRA SUBs can be safely driven
from the amp rack included. There is also space in the amp rack to allow
for a 3rd amplifier for any reason an application might require (sub extensi­on, separate front-/side-fill or monitor).

The largest sensible configuration of the COBRA– 2 system would consist of one full
COBRA – 2 system arrayed per side (4 TOPs and 4-6 SUBS per side). For espe­cially powerful and penetrating extended bass reproduction COBRA – 2 can be
enhanced utilizing the PWH bass horns, suitable for a wide range of music and venu­es. Up to 4 PWH subwoofers may be driven from the amp rack included.

Since doubling the number of COBRATOP enclosures halves their vertical radiation
angle, special attention must be paid to the way they are aligned - regardless of
whether they are flown or stacked.

A COBRA TOP has a coverage pattern of 120° x 30°, horizontal and vertical. Two
TOPs stacked have a coverage pattern of 120° x 15°. Three COBRATOPs stacked
have a coverage pattern of 120° x 11.25°, and four TOPs 120° x 7.5°.

COBRA-4 SYSTEM

The active 4-way COBRA-4 SYSTEM allows for the same reliability and ease of operation
as the COBRA 2, yet is capable to project across distances up to 250 ft for several thousand
people, depending on environmental and musical factors. With a FOH distance of 100 feet,
the COBRA 4 produces average SPL levels of 110dB in the mid-high range and 120 dB in the
bass range.

The COBRA 4 system includes four COBRA-4 TOP, two COBRA-4 FAR, eight COBRAPWH,
two pre-wired CSR 4 amp racks, all necessary speaker cables, and four 2.5° tilt boards.

To achieve necessary long throw distances, a COBRA 4 FAR is positioned
at the top of the line array. The low and mid frequency components arran­gement in the FAR are identical to the COBRA 4 TOP, however three EV
DH2T compression drivers loaded into a 5°-HF-waveguide are used to furt­her project the high frequency range with a dispersion of 90° x 5°.

Additional COBRA 4 FARs may be used to supplement COBRA 4 in appli­cations requiring extended coverage.

The COBRA PWH is a patented, horn-loaded subwoofer design delivering
improved directivity, and maximum efficiency creating a bass response tai­lored for sound reinforcement applications requiring maximum bass impact.

The illustration shows a medium-sized
COBRA-4 configuration for typical
medium-sized open-air events in a
city.
It consists of a COBRA-4 system and
additional PWH bass horns as well as
two line-arrays each consisting of four
flown COBRA-4 FAR and 1 - 2
COBRA-4 TOP cabinets. The lowest
of the COBRA-4 TOPs (nearfield) and
the COBRA-4 FAR adjacent have
each been tilted 5° downwards, whilst
the highest three COBRA-4 FARs
hang in a straight line. Using the adju­ster-belt, the central axis of these
three COBRA-4 FARs is aimed at the
most distant third of the area to be
covered. For particularly wide (> 15m)
applications, it makes sense to place
additional COBRA-4 TOPs on top of
the stacked COBRA PWH bass array,
to cover the area directly in front of the
stage.

Testimony

Chuck Walthall ( Walthall Associates USA )

"The Cobra´s high-fidelity purity and sonic output is very neutral and trans­parent from such a compact system, The vocal articulation and high-fidelity
impact is likened to a large scale system with massive amplification. The
package is perfectly fitted for small to medium P Aapplications and the "plug
& play” simplicity is second to none. One of the most important conside-

rations for any sound reinforcement crew is setup time and the Cobra
redefines plug & play in the audio industry, thus greatly reducing ope­rating costs by freeing up staff to work on the projects”.

Christopher Holder ( Audio Technology AUSTRALIA )

"For example, we were taking out a 6-tonne truck and now we´re travelling
with a 4-tonne truck – and it´s only two-thirds full. With Cobra we can travel
with less crew, get the gear in and out more quickly and have better sound.
So it just wins in all departments…
…..It´s completely stable top to bottom and at all levels – from idling to flat
out. There´s also a warmth that comes with the three-way driver configura­tion. If you go from a horn to an 8- or 12-inch, I don´t think you get that ama­zing clarity in the vocal range that Cobra´s midrange drivers offer”.

SONAR 2002 ( Barcelona SPAIN )

During the three days of Festival was arranged the COBRA-System sound
for LAB space, where was combined several performance of House, tech­no and chill-out music. Dynacord received from all the Sonar staff the con­gratulations, for the result and coverage of Festival. Mr. Pedri, the engineer

of Festival, said:” It´s great, the sound is like Hi-fi, unbelievable. It´s really
clear wherever you go from all the audience areas. It´s just Fantastic”.
