E-PAC Configuration for E12-SUB
CAUTION!
E12-SUB
The E12-SUB is a compact bass-reflex design employing a high
excursion 12" driver. The large, specially shaped reflex port
enables the E12-SUB to achieve high sound pressure levels with
minimal power compression and breathing effects.
The E12-SUB cabinet is constructed from marine plywood and has
an impact resistant paint finish. The front of the loudspeaker
cabinet is fitted with a rigid metal grill covered with a acoustically
transparent foam. The cabinet incorporates a steel handle in one
side and two parallel wired Speakon-NL4 connectors on the rear
panel.
Fitted to the top panel is an M20 threaded flange to accept the
Z5013 Loudspeaker stand for the deployment of a single E3
cabinet. To ensure sufficient stability the maximum permissible
weight of 10 kg (22 lbs) for the cabinet mounted on top of the
stand must not be exceeded.
Designed to be actively driven using the E-PAC Power Amplifier
Controller the E12-SUB covers the 50 Hz to 120 Hz frequency
band.
The compact E12-SUB has an extraordinarily high output
capability for a cabinet of such a size - enough to support up to
two E3 cabinets. It is ideal for permanent or mobile use in small
and medium venues.
Only operate the E12-SUB with a d&b E-PAC in E12-SUB
configuration (SUB configuration with E-PAC version 1), otherwise
there is a risk of damaging the loudspeaker components.
Connections
The E12-SUB cabinet is fitted with a pair of Speakon-NL4
connectors. All four pins of both connectors are wired in parallel.
The E12-SUB uses the pin assignments 2+/2–. Pins 1+/1– are
designated to C and E-Series full range cabinets. Using one
connector as the input, the second connector allows for direct
connection to additional loudspeakers.
Operation with E-PAC
To drive E12-SUB cabinets the E-PAC has to be configured to E12
mode by setting the appropriate DIP switches on the rear panel.
The configuration E12-SUB on E-PAC version 2 is identical to
configuration SUB on E-PAC version 1.
The E-PAC can drive a single E12-SUB at full output power.
Connecting a second E12-SUB requires LO IMP mode to be
selected on the E-PAC rear panel. Due to the 6 dB reduction of input
level to the speakers in low impedance mode there is no gain in
acoustical output.
DIP switches 1 and 2 (CUT and HFA) are not functional with the
configuration for E12-SUB.
