10.3 - B18 USING I-TECH 4X3500HD
When using Crown Audio I-Tech 4x3500HD amplifiers, up to four VTX B18 (1 x per circuit) subwoofers can be powered per amplifier.
Based on the B18 component resource requirements, this allows for optimum power-to-transducer ratio without compromising the
maximum SPL capabilities of the system. The example below illustrates how to connect 4 x VTX B18 cabinets to a 4-channel I-Tech HD
amplifier using standard 4-conductor NL4 cables. The channel selection switch at the back of each B18 is used to assign each cabinet
to the appropriate amplifier channel.
