Under the umbrella of professional audio equipment, the Complete HD4 VRack Amplification Rack on Wheels with 3x 3500HD Amplifiers stands out as a comprehensive, high-performance solution for all your sound amplification needs. This all-in-one system from Crown simplifies the demanding process of performance setup, allowing your technical team to focus on other crucial tasks.
The VRack is a turnkey amplification package, meticulously designed for optimal performance and setup simplicity. It comes with Crown-engineered components pre-installed, eliminating the need for time-consuming assembly. This robust system delivers exceptional power distribution globally, making it a versatile choice for performances around the world.
The VRack is equipped with the advanced Crown OMNIDRIVEHD Digital Signal Processing, which includes LevelMax Limiters, superior FIR Filters, and innovative Power Factor Correction technology. This ensures optimal output at all AC main voltages and frequencies. The system also features a 5 pin CEE form and 5 pin Hubbell Twist Lock, with one amplifier per phase for enhanced control.
The innovative software of the VRack allows for monitoring and adjustment on a rack-by-rack basis. All changes for all three amps can be made with one interface, providing a streamlined user experience. The system also monitors input metering (peak and RMS), output metering (peak and RMS), and overall gain reduction. The built-in network and AES failover ensure continuous operation even in the event of an AC failure.
The VRack's versatility is further highlighted by its ability to support multiple configurations for different types of speakers. It accepts AES, VDrive, Analog, and Network inputs for multiple connections. Its dimensions are designed for easy shipment, fitting US and European truck configurations, sea containers, and more. The captive suspension offers lifting and hoisting options for venue flexibility.
The I-Tech 4x3500HD amplifier, the industry's first high-powered tour sound amplifier, is a key component of the VRack. It features four inputs - Analog, AES3, and CobraNet - fully routable to any one of 4 outputs. Each channel is equipped with a complete set of OMNIDRIVEHD Processing, including the acclaimed LevelMAX Limiter Suite, and support for linear phase FIR filters as used in the latest JBL V5 loudspeaker tunings. Crown's patented Class-I technology ensures uncompromising power output across all four channels.
The VRack also boasts a true Ethernet backbone for fast, reliable, and scalable operation. The color LCD provides users with diagnostics and presets for easy setup. The front panel USB connector allows for easy transfer of presets to/from a USB drive to the amp's DSP. The new software interface, developed based on customer feedback, manages presets, provides easier system-level changes, and includes a configuration wizard.
The VRack is the only product available with analog, AES, CobraNet, HiQnet, and Ethernet connectivity. It uses BSS OMNIDRIVEHD DSP processing with industry-leading IIR filters and linear phase FIR filters. The high common-mode rejection eliminates hum and RFI on input cables. The full power-supply voltage is always available, allowing instantaneous power on demand. The quality-graded components let you safely drive the amplifier harder, while the total capacitance provides tremendous energy reserves for power bursts.
In conclusion, the Complete HD4 VRack Amplification Rack on Wheels with 3x 3500HD Amplifiers is a comprehensive, high-performance, and versatile solution for all your sound amplification needs. It stands unmatched in its category, providing four routable inputs to any output, and a global power supply that accepts 100-240VAC, 50/60 Hz ( +/-15%).
