Operation with D6 or D12
Select the controller setup E9.
Within the D12 amplifier this is available in "Dual Channel" and "Mix
TOP/SUB" mode.
IMPORTANT!
Up to a total of two E9 loudspeakers can be driven by each D6 or D12
amplifier channel.
In applications with low continuous levels and low ambient temperatures
up to three cabinets can be connected to a D12 channel.
When the D12 is operated in "Mix TOP/SUB" mode, the E9 cabinet
and a respective active subwoofer can be linked together locally and
fed by a single 4-wire cable from either amplifier output connector.
To apply SenseDrive for the subwoofer, EP5 connectors and 5-wire
cables have to be used. When operated in "Mix TOP/SUB" mode,
subwoofers have to be fed from the output B connector of the D12
amplifier.
Controller settings
For acoustic adjustment the settings CUT and HFA can be selected.
CUT circuit
Set to CUT, a high pass filter with a 110 Hz cut off frequency is inserted
in the controller signal path. The E9 is now configured for use with d&b
active subwoofers.

Fig. 3: Frequency response of HFA circuit
In HFA mode (High Frequency Attenuation), the HF response of the E9 is
rolled off. The HFA circuit provides a natural, balanced frequency
response when a unit is placed close to listeners in near field or delay
use.
High frequency attenuation begins gradually at 1 kHz, dropping by
approximately 3 dB at 10 kHz. This roll off mimics the decline in
frequency response experienced when listening to a system from a
distance in a typically reverberant room or auditorium.
Operation with E-PAC
Fig. 4: E-PAC configuration for E9
(E-PAC version 2)
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 the encoder in
conjunction with an LCD.
Selecting E9 mode enables the E-PAC to drive one E9 cabinet. LO IMP
mode allows the E-PAC to drive up to two E9 cabinets with a 6 dB
reduction of input level to the loudspeakers.
The CUT and HFA settings are available. The characteristics of the CUT
and HFA settings are explained in the previous section "Operation with
D6 or D12 - Controller settings".
