B18 Using I-Tech 4X3500Hd (Cardioid); Crown V-Rack - JBL VTX Series User Manual

10.4 B18 USING I-TECH 4X3500HD (CARDIOID)

Cardioid configurations can be created using Crown I-Tech 4x3500HD amplifiers. In this case, anyone of the amplifier channels can be
set for cardioid using Performance Manager. 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 configuration, the front grill NL4 connectors
are used for wiring the rear-facing B18 subwoofers.
