8.2 USING THE A12 WITH CROWN I-TECH 12000HD
A pair of Crown I-Tech 12000HD amplifiers can power up to three VTX A12 loudspeakers. One Crown I-Tech 12000HD powers the low
frequency section, while the other drives the mid and high frequency sections. Based on the power demands of the A12, this allows for
optimum power-to-transducer ratio without compromising the maximum SPL capabilities of the system. When finer control of coverage
in a venue is needed, smaller coverage areas can be created by using circuits of two cabinets.

8.3 CROWN AUDIO V-RACK
VTX A12 systems are compatible with the Crown V-Rack 12000HD and Crown V-Rack 4x3500HD touring racks. The number of sup-
ported cabinets per amplifier and wiring options remain the same as the Crown I-Tech examples illustrated in this document. For more
information on the Crown V-Rack products, refer to the V-Rack User Manuals and documentation.
TIP: Other channel assignments can be implemented when using two-channel Crown I-Tech HD amplifiers. Use JBL’s Per-
formance Manager control software to assign speaker presets.
CAUTION: Make sure the total number of VTX A12 enclosures per circuit/amplifier does not exceed the recom-
mended maximum .
