7 - AMPLIFICA TION & WIRING

Like all other VTX systems, the A6 and B15 are powered exclusively by Crown I-Tech HD amplifiers, providing consistency and opti-

mum performance anywhere in the world. All speaker processing is performed by the I-Tech HD's internal processing, which includes

the advanced LevelMax

three-stage limiter suite, to ensure proper, reliable operation under any conditions. LevelMax incorporates

excursion control, RMS limiting, and long-term thermal protection for the transducers. I-Tech HD amplifiers also offer a user-adjustable

input section for equalization, time alignment, and electronic delay steering. Standard JBL presets are available for both the Crown

I-Tech 4x3500HD and I-Tech 12000HD. The most up-to-date presets are available for download from www.jblpro.com, and bundled in

the latest version of Performance Manager control software.

When using Crown I-Tech 4x3500HD amplifiers, up to 16 VTX A6 loudspeakers can be powered per amplifier, four per circuit group.

Circuit groups with two or three cabinets can be used to create smaller coverage areas in the venue for finer control. The example be-

low illustrates how to connect 16 VTX A6 cabinets to an I-Tech 4x3500HD amplifier using standard four-contact NL4 cables and the A6

channel selection switch.
