E-PAC Configuration for
C6 (E-PAC version 2)
Operation with P1200A
Up to two C6 loudspeakers can be driven by each P1200A power
amplifier channel. Fitting one C6-CO and one subwoofer
controller module allows a single mainframe to drive two C6 and
two active subwoofer cabinets (E18-SUB, C4-SUB or C7-SUB). All
cabinets can be linked together locally and fed by a single four-
wire cable from either mainframe output connector.
C6 controller module switches
Standard setting
If the CUT switch and MON switch are not selected the module is
configured for use with C6 loudspeakers used as a stand alone
system without subwoofers.
CUT switch and indicator
Set to CUT, a high pass filter with a 110 Hz cut-off frequency is
inserted in the controller signal path. The yellow CUT LED
illuminates. The C6 system is now configured for use with d&b C-
Series active subwoofers.
MON switch and indicator
If the MON switch is selected the yellow MON LED illuminates and
the low frequency level is reduced by 3 dB. This setting particularly
applies to the C6-MON as this setting reduces the low frequency
energy gained from the coupling effect of floor placement.
160Hz setting (CUT and MON switches both selected)
If the 160Hz mode is selected, a high pass filter is inserted in the
controller signal path. The crossover frequency of 160 Hz is higher
than in CUT mode and thus increases the available headroom in
the C6 system. The 160Hz mode can be selected when the system
is operated with d&b subwoofers C4-SUB, C7-SUB or E18-SUB
(also in 160Hz mode, see manual section E18-SUB). This
configuration is particularly useful when C6 loudspeakers are
stacked directly on top of the subwoofer system.
Operation with E-PAC
To drive C6 cabinets the E-PAC has to be configured to C6 mode
by setting the appropriate DIP switches on the rear panel (only
possible with E-PAC version 2).
The E-PAC can drive a single C6 cabinet at an output power of
300 watts. The rear panel LO IMP switch configures the E-PAC to drive
two C6 cabinets with a 6 dB reduction of input level to the speakers.
DIP switches 1 and 2 respectively allow CUT and HFA settings to be
selected. The characteristics of the CUT setting are explained
above under the section "C6 controller module switches".
The functions MON and 160Hz are not available with the E-PAC
controller.
