Operation with P1200A
Up to two E9 loudspeakers can be driven by each P1200A power
amplifier channel. Fitting one E9-CO and one subwoofer controller
module allows a single mainframe to drive two E9 and two active
subwoofer cabinets (E18-SUB or C7-SUB). All cabinets can be
linked together locally and fed by a single four-wire cable from
either mainframe output connector.
The E9 can also be used with the E15-BX bass extension cabinet.
The E15-BX cabinet is equipped with a passive crossover network
and simply connects in parallel with the E9 cabinet without the
need for any additional control electronics. One E9 and one E15-
BX cabinet can be driven by each P1200A output channel.
E9 controller module switches
Standard setting
If the CUT switch and BX switch are not selected the module is
configured for use with E9 loudspeakers when 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 E9 system is now configured for use with d&b C or
E-Series active subwoofers.
BX switch and indicator
When the E9 is used with the passive E15-BX subwoofer, i.e. E9
and E15-BX are linked to the same amplifier output, the BX switch
should be selected. The LF level - boosted by the bass extension
cabinet - is then attenuated by 3 dB, thereby increasing headroom
at bass frequencies.
When E9 loudspeakers are deployed as stage monitors selecting the BX
switch reduces the low frequency energy gained from the coupling
effect of floor placement.
SUB (CUT and BX both selected)
Selecting the CUT and BX switches activates a lowpass filter. The
module now transmits frequencies from 50 to 110 Hz only, allowing
the d&b E15-BX to be driven as an active subwoofer.
The E9-CO drives Speakon pins 1+/1

(EP-5: 1/2). Therefore the
SUB setting is not suitable to drive d&b C/E-Series active
subwoofer cabinets.
Operation with E-PAC
To drive E9 cabinets the E-PAC has to be configured to E9 mode.
For an E-PAC version 2, the configuration is selected by setting the
appropriate DIP switches on the rear panel.
For an E-PAC version 3, the configuration is set via a front panel
digital rotary encoder in conjunction with an LCD.
The CUT and HFA settings are available on versions 2 and 3. The
characteristics of the CUT setting are explained on the previous
page under the section "E9 controller module switches". The
functions BX and SUB are not available with the E-PAC controller.
