VT X A12 | User Manual

7.2 - CROWN I-TECH 12000HD

When using Crown Audio I-Tech 12000HD ampliﬁers, up to 3 VTX A12 loudspeakers can be powered per pair of am-

pliﬁers. 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 A12 component resource requirements, this allows for optimum power-to-transducer

ratio without compromising the system’s maximum SPL capabilities. Circuits of 2 cabinets can be used when higher

circuiting resolution is necessary.

VTX A12 systems are compatible with the Crown Audio V-Rack 12000HD and Crown Audio V-Rack 4x3500HD touring

racks. The number of supported cabinets per ampliﬁer and wiring options remain the same as the Crown Audio I-Tech

examples illustrated in this document. For more information on the Crown Audio V-Rack products, refer to the V-Rack

User Manuals and documentation.

CAUTION: Make sure the total number of VTX A12 enclosures per circuit / ampliﬁer does not exceed the

maximum number recommended.

TIP: Other channel assignments can be implemented when using the 2-channel Crown Audio I-Tech HD ampli-

ﬁers. Use JBL’s HiQNet

Performance Manager

control software to assign speaker presets.
