Crown VRack 12000HD - Complete Vertical Rack with Casters and 3x I-Tech 12000HD Power Amplifiers in Black Finish

The Crown VRack 12000HD is a complete, high-performance amplifier solution designed for touring sound professionals, featuring three Crown I-Tech 12000HD amplifiers housed in a rugged vertical rack with built-in casters for easy mobility. It is a fully assembled and internally connected amplifier package, delivering a powerful, flexible, and reliable audio solution for large-scale live sound reinforcement. With Crown's proven I-Tech 12000HD amplifiers at its core, the VRack 12000HD simplifies the process of system integration and offers enhanced performance, reduced setup time, and optimized connectivity options for both analog and digital systems.

Each I-Tech 12000HD amplifier within the VRack offers two channels of high-power amplification, capable of delivering up to 4500W at 4 ohms or 2100W at 8 ohms per channel, with an additional bridged mode providing up to 9000W at 8 ohms. This immense power output is ideal for driving a wide variety of speaker systems, including JBL's VerTec and VTX line arrays, STX800 models, and their corresponding subwoofer systems. The VRack is meticulously engineered to provide a complete, turnkey amplification solution, and is tested to stringent standards to ensure consistent, reliable performance across the globe.

The VRack 12000HD features a thoughtfully designed input and output panel to maximize flexibility during deployment. The input panel, located at the top rear of the rack, provides connectivity for analog XLR inputs, AES/EBU digital audio inputs, and CobraNet network connections, all engineered to simplify complex audio routing. Additionally, the input panel's built-in AES buffering eliminates the need for digital distribution amplifiers, streamlining the signal chain and ensuring reliable signal distribution across large systems. The rack's output panel, situated at the bottom rear, is equipped with 12 Speakon connectors, offering a versatile range of configurations, including 2-way NL4 outputs, 1-way NL4 outputs, and 3-way NL8 outputs, making it easy to integrate with a wide variety of speaker setups and system designs.

One of the standout features of the VRack 12000HD is its ability to seamlessly integrate into both analog and digital audio environments. The VDrive feature allows for Ethernet control and AES digital audio distribution over a single Cat5 cable, enabling users to jump from rack to rack without the need for additional cabling. This built-in digital distribution capability provides users with the flexibility to control and monitor the system from a single interface, utilizing Crown's HiQnet protocol for comprehensive network control and system management. The VRack's fail-over AES and network connection further enhances system reliability, ensuring uninterrupted performance even in the event of a signal failure.

To enhance durability and ease of use on the road, the Crown VRack 12000HD is constructed with a shock-mounted rack for maximum protection during transport, while the inclusion of rear rack lighting makes it easier for technicians to work in dimly lit environments. The front-mounted power panel offers both 5-pin Hubbell Twist-Lock and 5-pin CEE-Form connectors, providing compatibility with worldwide power standards, and the rack's built-in captive suspension ensures secure and stable mounting during operation. For added convenience, the VRack comes with a removable dolly board for easy transport, as well as side-storing rack doors that help protect the system during transit.

The Crown VRack 12000HD is designed not just as a simple amplifier rack, but as a modular building block for larger sound reinforcement systems. Its 3:2 ratio of amplifiers to speakers ensures optimal system performance, making it ideal for powering a combination of tops and subs in professional PA setups. Whether used for large concerts, festivals, or other live sound applications, the VRack 12000HD provides unmatched power, flexibility, and ease of integration, backed by Crown's legendary reliability and advanced amplifier technology.
