C4-SUB

The  C4-SUB  is  a  compact,  hornloaded  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  and  has
an  impact  resistant  paint  finish.  The  front  of  the  loudspeaker
cabinet  is  fitted  with  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.  The
cabinet  incoporates  two  steel  handles  and  MAN  CF4  stud  plate
rigging  points.  Mounted  on  the  rear  panel  are  ratchet  strap  guide
plates (kelping bars) and four heavy duty wheels.

CAUTION!

Only operate C4-SUB cabinets with a d&b D12 or E-PAC amplifier
in  C4-SUB  mode  or  a  P1200A  mainframe  fitted  with  a  C4-SUB
controller  module,  otherwise  there  is  a  risk  of  damaging  the
loudspeaker components.

Connector wiring

The C4-SUB cabinet is fitted with a pair of EP5 connectors. All pins
of both connectors are wired in parallel.
The C4-SUB uses the pin assignments 3/4 and 5 (Pin 5: SenseDrive
- D12 only and in conjunction with 5-wire cables).
Pins 1/2 are designated to d&b full range systems.

Using  one  connector  as  the  input,  the  second  connector  allows  for
direct connection to additional cabinets.

The  C4-SUB  can  be  supplied  with  NL4  connectors  as  an  option
using the pin assignment 2+/2–. Pins 1+/1– are designated to d&b
full range systems.

Pin  equivalents  of  EP5  and  NL4  connectors  are  listed  in  the  table
below.
