6. CONFIGURATIONS COBRA-SYSTEM ( SUB / TOP )
The following illustrations show the basic set of an active 2-way COBRA SYSTEM comprising COBRA TOP
and COBRA SUB enclosures along with various expansion possibilities. The basic set comprising 4 COBRA
TOPs and 4 COBRA SUBs is designed for high quality sound reinforcement for events in smallish
marquees and halls and for projection over distances of up to 40 metres providing coverage for around
1000 square metres. The COBRA SYSTEM generates a maximum SPL of 137 dB L + 137 dB R in the
mid/high frequency range and up to 141 dB in the low frequency range.
COBRA SYSTEM
The COBRA SYSTEM basic se
consists of 4 x COBRA TOPs, 4
COBRA SUBs, 1 X CSW 25 (2.5°
wedge set), a ready-wired amp rac
CSR-12 and the appropriate 4-wire
system cables for the loudspeake
enclosures.
The integrated DSP 244 controlle
(stereo 2-way mode) provides the two
integrated L2400 power amplifiers with
sub and mid/high frequency signals.
The signal from the power amplifiers is
available on the Speakon connectors
of the integrated CP-44 connecto
panel. Each stack (L and R) is then
powered via a 4-wire system cable,
with the signal being looped through
from enclosure to enclosure.
lso to be found on the front panel are
the XLR sockets for LF control of the
rack, the 16A CEE plug for the 3-phase
power supply and the XLR In/Ou
sockets for the RS-485 connection o
the DSP 244 (retrofittable).
For maximum expandability, the Cobra
Rack CSR-12 offers the possibility o
integrating a further power amplifie
with 3U (sub-extension or monitor) and
their power supply via the CP-44
connector panel
