Operation with D12

Selecting C7-SUB mode in the D12 enables up to two C7-SUB

cabinets to be driven by each channel. In applications with low

continuous levels and low ambient temperatures up to three

cabinets per channel may be connected.

When the D12 is operated in "Mix TOP/SUB" mode C7-SUB

cabinet and a respective full range system 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

the subwoofer has to be fed from the output B connector of the

D12 amplifier.

Controller settings

For acoustic adjustment the 100 Hz setting can be selected.

100 Hz

If the 100 Hz setting is selected, the upper operating frequency of

the system is reduced from 140 Hz to 100 Hz. This setting allows

the C7-SUB to supplement TOP cabinets in full range mode (i.e.

CUT not selected).

The 100 Hz setting may also be used with TOP cabinets in CUT

mode to compensate for room resonances often found in the

125 Hz band.

Operation with E-PAC (Version 3 with display only)

Selecting C7-SUB mode in the E-PAC enables one C7-SUB cabinet

to be driven at an output power of 300 Watts. We do not

recommend that two C7-SUB cabinets are driven in LO IMP mode as

the 6 dB reduction in input level to the loudspeakers results in no

gain in acoustical output.

The 100 Hz setting is available. The characteristics of the 100 Hz

setting is explained under the previous section "Operation with

D12 - Controller settings".

Operation with P1200A

Up to two C7-SUB cabinets can be driven by each P1200A power

amplifier channel fitted with a C7-SUB controller module. Fitting

one C7-SUB and one TOP controller module allows a single

mainframe to drive two C7-SUB and two TOP cabinets. All cabinets

can be linked together locally and fed by a single 4-wire cable

from either mainframe output connector.

The 100 Hz setting is available. The characteristics of the 100 Hz

setting is explained under the previous section "Operation with D12

- Controller settings".
