Dynacord COBRA-4 TOP [10/16] Cobra 4 system

Dynacord COBRA-4 TOP [10/16] X csr 4
8. COBRA-4 SYSTEM ACTIVE 4-WAY
The active 4-way COBRA-4 SYSTEM is designed for distances of up to 80 metres in medium-sized
marquees, halls and open air events and produces the SPL at the FOH position 30 metres away typically
required by TOP 40 bands: 110 dB in the mid/high- and up to 120 dB in the low frequency range.
The maximum SPL of the system at 1 metre is 140 dB L + 140 dB R in the mid/high frequency range and
with bass horns arranged in a central cluster up to 150 dB in the low frequency range.

The illustration shows the COBRA-4 SYSTEM consisting of 2 x COBRA-4 FARs, 4 X COBRA-4 TOPs, 8x
COBRA-PWH, 2 x CSW 25 wedge sets and 2 x CSR-4 amp racks.
Through the use of 2 x COBRA-4 TOPs and 1 x COBRA-4 FAR per side, even in the typical stacked
configuration optimal line array performance can be achieved without expensive adjustments.
The high frequency range in the nearfield of the PA is particularly widely dispersed by the COBRA-4 TOP
and therefore reaches the area directly in front of the stage.
For long distances, the COBRA-4 FAR is used. This is placed at the top of the array and has a horizontal
directivity of 90° and a vertical directivity of 5° in the high frequency range. In the low frequency and mid
ranges, the same components as those of the COBRA-4 TOP are used, thereby providing the optimal
extension to the low and midrange line array.
In all, eight COBRA PWH bass horns are used to produce the power and projection in the bass region
demanded by TOP 40 bands and can be stacked or employed as a horizontal line array depending upon the
requirements of the venue. A variety of grooves are provided on the top and sides of the enclosures to allow
maximum flexibility (see chapters 6 and 7).
The COBRA-4 SYSTEM is powered via ready cabled CSR-4 amp racks stationed alongside the enclosures.
These contain a DSP 244 controller, 2x L 2400 and CP-84 connector panel.
The cabling of the active 4-way COBRA-4 SYSTEMS is done through the CP-84 panel via 8-wire system
cables for the COBRA-4 TOP and COBRA-4 FAR enclosures whilst the COBRA PWH bass horns are
connected using 8-pins (optional 4-pins).
