Operation with D6 or D12
Passive operation connected in parallel to E8
Select the E8-X setup when E8 cabinets are used in combination with
E12X-SUB loudspeakers on the same channel. Compared to the
standard E8 setup the X version provides a dedicated correction for the
combined frequency response of these systems. D12 amplifiers have to
be set to “Dual Channel” to access these.
IMPORTANT! Selecting the E8-X setup enables a combination of up to three E8 or
E12X-SUB loudspeakers to be driven by the respective D12 or D6
channel.
In applications with low continuous levels and low ambient
temperatures up to four cabinets can be connected to a D12 channel.
Active operation
Select the E12-SUB setup to drive E12X-SUB in active mode. E-Series
full range cabinets should now be operated in CUT mode to increase
the system headroom. Within the D12 amplifier the E12-SUB setup is
available in “Dual Channel” and “Mix TOP/SUB” mode.
IMPORTANT! Selecting the E12-SUB setup enables up to two E12X-SUB loudspeakers
to be driven by the respective channel.
In applications with low continuous levels and low ambient temperatures
up to three cabinets can be connected to a D12 channel.
To apply SenseDrive for the subwoofer, EP5 connectors and 5-wire
cables have to be used. When operated in Mix TOP/SUB" mode, the
subwoofer has to be fed from the output B connector of the D12
amplifier.
Controller settings
140 Hz circuit
If the 140 Hz circuit is selected the upper operating frequency of the
system is raised from 100 Hz to 140 Hz. It can be used to supplement
E-Series cabinets in CUT mode when the coupling of the systems
requires more energy in this frequency band.
Operation with E-PAC
Selecting E12-SUB mode enables the E-PAC to drive one E12X-SUB
loudspeaker.
The 140 Hz setting is available. The characteristics of the 140 Hz setting
are explained in the previous section "Operation with D6 or D12 -
Controller settings".
