controller module
Up to four E3 cabinets can be driven by each P1200A power amplifier
channel fitted with an E3 controller module. Fitting one E3 and one
subwoofer controller module allows a single mainframe to drive four
E3s and two active subwoofer cabinets. All cabinets can be linked
together locally and fed by a single 4-wire cable from either mainframe
output connector
The CUT and HFA settings are available. The characteristics of the CUT
and HFA settings are explained in the previous section "Operation with
D6 or D12 - Controller settings".
Dispersion characteristics
The diagrams below show dispersion angle vs frequency plotted using
