10.4 - B18 USING I-TECH 4X3500HD (CARDIOID)
Cardioid configurations can be created using Crown Audio I-Tech 4x3500HD amplifiers. In this case, anyone of the amplifier channels
can be set for cardioid using JBL Performance Manager
TM
software application. Each amplifier channel is driving a single B18 enclosure
and the channel selection switch at the back of the B18s can be used to assign B18 cabinets to the cardioid channels. In this configu-
ration, the front grill NL4 connectors are used for wiring the rear facing B18 subwoofers.
