E12-SUB Manual
Operation with D6 or D12
Select the controller setup E12-SUB.
Within the D12 amplifier this is available in "Dual Channel" and "Mix
TOP/SUB" mode.
Up to a total of two E12-SUBs 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, E12-SUB cabinets
and respective full range systems 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 140 Hz function can be selected.
140 Hz circuit
If the 140 Hz setting is selected, the upper operating frequency of the
system is increased from 120 Hz to 140 Hz. This setting allows the E12-
SUB to operate with up to four E0 loudspeakers.
Operation with E-PAC
Selecting E12-SUB mode enables the E-PAC to drive one E12-SUB
loudspeaker.
For an E-PAC version 1 or 2, the configuration is selected by setting the
appropriate DIP switches on the rear panel. The E12-SUB configuration
on E-PAC version 2 is identical to the SUB configuration on E-PAC

higher). The characteristics of the 140 Hz setting are explained in the
previous section "Operation with D6 or D12 - Controller settings".
