8.2 - A8 ON CROWN I-TECH 4X3500HD AND NL8 CABLES
Standard NL8 cables can be used to connect VTX A8 cabinets to a Crown Audio I-Tech 4x3500HD amplifier using the VTX NL824, NL8
to 2 x NL4 breakout cable. Using this breakout cable, up to 6 x VTX A8 cabinets can be connected to a 4 x channel amplifier using a
single NL8 cable, saving cables and simplifying wiring.
8.3 - A8 ON CROWN I-TECH HD (2-CH)
When using Crown Audio I-Tech HD amplifiers (2-Channel), up to 3 VTX A8 loudspeakers can be powered per pair of amplifiers. One
Crown I-Tech 12000HD is used for powering the low-frequency section and another for the mid- and high-frequency sections. Based on
the A8 component resource requirements, this allows for optimum power-to-transducer ratio without compromising the system’s max-
imum SPL capabilities. Circuits of 2 cabinets can be used when higher circuiting resolution is necessary. The example below illustrates
how to connect 3 x VTX A8 cabinets to a 2-channel I-Tech HD amplifier using a standard 4-contactor NL4 cable.
