Connections
Fig. 4: Connector wiring
The E6 cabinet is fitted with a pair of EP5 connectors. All five pins of
both connectors are wired in parallel. The E6 uses the pin assignments
1/2. Pins 3/4 and 5 are designated to active subwoofers, where pin 5 is
used for SenseDrive (only available when using a D12 amplifier and 5-
wire cabling). Using the male connector as the input, the female
connector allows for direct connection to additional loudspeakers.
The E6 can be supplied with NL4 connectors as an option.
Pin equivalents of EP5 and NL4 connectors and the fixed cable option
are listed in the table below.
EP5 1 2 3 4 5
NL4 1+ 1– 2+ 2– n.a.

Operation with D6 or D12
Select the controller setup E6.
On the D12 amplifier it is available in “Dual Channel” and “Mix
TOP/SUB” mode. For combinations with active subwoofers fed by a
single 4/5-wire cable "Mix TOP/SUB" mode must be selected.
Up to a total of four E6 loudspeakers can be driven by each channel of
the D6 or D12 amplifiers.
Controller settings
For acoustic adjustment the functions CUT, HFA and CPL can be
selected.
CUT circuit
Set to CUT, the E6 low frequency level is reduced. The E6 is now
configured for use with E12X-SUB or E15X-SUB in active mode or other
d&b active subwoofers.

Fig. 5: Frequency response correction of
HFA circuit
In HFA mode (High Frequency Attenuation), the HF response of the E6
system 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.
