10. SYSTEM AMP RACKS
The two illustrations show the internal cabling of the COBRA SYSTEM RACK from the rear. The control of
the active 2-way COBRA and active 4-way COBRA-4 SYSTEMS is effected by their respective system
racks (CSR-12 in the case of the COBRA SYSTEM and CSR-4 in the case of the COBRA-4 SYSTEM) which
come pre-wired and factory-programmed.

In the CSR-12, the DSP 244 controller
operates in stereo 2-way mode and
provides the integrated L 2400 power
amplifiers
with
sub
signals.
The output signals of the L 2400 power
amplifiers (TOP above and SUB below)
are connected internally to the 4-pin
system sockets at the CP-44 front
panel (Sub signals on 1+/1- and
mid/high signals on 2+/2-).
Mains power is provided by the 16 A
CEE plug on the front panel and the 4
Schuko sockets at the rear (L1 – sub-
amp, L2 – mid/high amp and controller,
L3 – free).
The XLR In/Out sockets on the front for
RS-485
control
internally to the DSP 244 and after
conversion of the controller allow the
rack to be controlled remotely from a
PC using CrossMax editor software.
In the CSR-4, the controller operates in
mono 4-way mode and provides the
lower L 2400 with a sub signal on
Channel A and a low signal on
Channel B. The upper L 2400 is
provided with mid signals on Channel
A and high signals on Channel B.
The outputs of the power amplifiers are
connected to the 4- and 8-pin system
sockets of Channel A on the front
panel. The complete LF control of the
rack is also effected via Channel A.
The Sub signal is available on the 4-pin
system sockets on pins 1+/1-. The
remaining signals are on the 8-pin
system sockets (Low – 2+/2-, Mid –
3+/3- and High – 4+/4-) and drive the
stacked or flown TOP and FAR
cabinets via a single cable.
RS-485 and AC connectors are also
available as described for the CSR-12.
