C4-SUB
The C4-SUB is a compact, horn-loaded bandpass design employing
a single 18" driver. It is designed for use with the C4-TOP cabinet
as a part of the C4 System.
The C4-SUB cabinet is constructed from marine plywood, fitted
with steel handles, MAN CF4 stud plate rigging points and has an
impact resistant paint finish. The front of the loudspeaker cabinet is
protected by a rigid metal grill, covered with a replaceable
acoustically transparent foam and fitted with catches to the top
and bottom for securing an optional transport lid E7908. Mounted
on the rear panel are ratchet strap guide plates (kelping bars), four
M10 threaded inserts for attaching installation hardware, two
Speakon NL4 or EP-5 connectors wired in parallel and four heavy
duty wheels.
Designed to be actively driven using the d&b P1200A mainframe,
the C4-SUB is normally used to support the C4-TOP cabinet by
covering the 50 Hz to 150 Hz frequency band.
The C4-SUB cabinet has the same dimensions and shape as the C4-
TOP and is also fitted with the same hardware so that arrays,
ground-stacked or flown, using different combinations of these
cabinets can be speedily built and deployed.
However, the C4-SUB can also be used with other d&b C-Series
and F-Series systems. This is particularly important when these
systems require flown subwoofers.
Only operate C4-SUB loudspeakers with a d&b P1200A mainframe
fitted with C4-SUB controller modules otherwise there is a risk of
damaging the loudspeaker components.
Connections
The C4-SUB cabinet is fitted with a pair of Speakon-NL4
connectors. All four pins of both connectors are wired in parallel.
The C4-SUB uses the pin assignments 2+/2. Pins 1+/1 are
designated to d&b C- and E-Series full range systems. Using one
connector as the input, the second connector allows for direct
connection to additional loudspeakers.
The C4-SUB can be supplied with EP-5 output connectors as an
option. Pin equivalents of Speakon-NL4 and EP-5 connectors are
listed in the table below.
Operation with P1200A
Up to two C4-SUB's can be driven by each P1200A power
amplifier channel. Fitting one C4-SUB-CO and one C-Series TOP
controller module allows a single mainframe to drive two C4-SUB
and two mid/high cabinets. All cabinets can be linked together
locally and fed by a single four-wire cable from either mainframe
output connector.
Operation with E-PAC (only possible with E-PAC
version 3 with display)
To drive C4-SUB cabinets the E-PAC has to be configured to
C4-SUB mode.
