VRack: The Ultimate Solution for Touring with JBL VTX Speakers


The VRack is designed specifically for use with JBL VTX speakers, offering unparalleled convenience and efficiency for touring professionals. With easily removable wheel castors, VRacks can be effortlessly stacked, saving valuable space at venues and during transport.These racks come with built-in rigging features, making setup and teardown a breeze. 

Integrating various amp configurations into Performance Manager allows for seamless system design, monitoring, and control from designated positions. Equipped with comprehensive networking, inputs, outputs, and power distribution, VRacks ensure a simplified and reliable deployment every time.

GLOBAL POWER AT YOUR COMMAND


With your choice of three I-Tech 12000HD or I-Tech 4x3500HD amps in each VRack, power concerns are not a concern at all. The completely original switching power amp design provides greater fidelity at high and low power levels, more efficiency because it produces less waste heat, and more reliability because it’s not subjected to excessive heat or stressed to its limits. With constant access to full rail voltage, you’ll always have power on demand, and it greatly extends the V-I Plane boundaries to drive speaker loads no other amplifier can.

Crown’s innovative Power Factor Correction technology, optimal output at all AC main voltages and frequencies, and one amp per phase are all factors that produce the unrivaled power generated by the VRack. And that’s just some of the perks of the package; global power distribution is made possible by the 5 pin CEE Form and 5 pin Hubbell® Twist-Lock® on the power distro which, along with the rigging hardware and rack itself, are safety-certified to UL/CSA/ETL standards for local fire and safety inspections. The power distro, rigging hardware and entire rack are all safety-certified to UL/CSA/ETL standards for local fire and safety inspectors.

PERFORMS BEAUTIFULLY – EVERYWHERE


Your venue hosts a variety of performances; the VRack handles a variety of venues. Designed in conjunction with JBL® for all VerTec® loudspeakers, its output flexibility also allows multiple configurations for any loudspeaker in your inventory. The VRack has AES, VDrive, Analog and Network inputs for multiple connections; the setup process is greatly simplified and more efficient. With the flip of a switch, you can run 120VAC or 208VAC in the U.S. or 220VAC to 240VAC for international venues. The optional captive suspension frame saves performance space and eliminates long speaker wire runs with numerous lifting and hoisting options. The VRack’s versatility extends to delivery as well, since its dimensions permit easy shipment on U.S. and European truck configurations, sea containers and other transportation modes.

RUN THE SHOW WITH EASE

For a performance, controlling the sound is essential, and the VRack puts effortless control capabilities at your fingertips. HARMAN’s HiQnet Audio Architect™ and Performance Manager™ software allows system monitoring and adjustment on a rack-by-rack basis, and you can make any changes for all three amps – to monitors, main PA, side fills, etc. – with just one interface. You can also monitor peak and RMS input and output metering, plus overall gain reduction. The built-in network and AES failover protects speakers in case of AC mains loss, with standardized package configurations designed to optimise speaker performance. The VRack’s “go anywhere” ability also means greater cross-renting options, providing an added financial benefit.

Additional sound control comes from BSS Audio’s superior OMNIDRIVEHD™ Digital Signal Processing which produces ultra-smooth, sonically pure signal processing that’s four times faster than stand-alone processors. The LevelMAX™ Limiters guarantee a smooth response for superb sound and more usable peak SPL, while the audibly superior FIR Filters provide more than 10dB of additional stop band attenuation with greatly improved clarity.

VDRIVE WIRING SCHEMATIC

VDrive is a digital AES3 transport mechanism that combines a standard 10/100MB network connection with AES3 signals. VDrive uses the unused pins of a 10/100MB network to transport AES3 digital audio signals. As indicated in the top right chart, one is able to transmit 4 channels of digital audio using a standard CAT5 cable.

The idea behind VDrive is to connect your VRacks in a ring topology, feed AES3 into the first rack and select the switch of which AES3 stream (1/2 or 3/4) to send via the CAT5 connection to the next VRacks in the network ring. On the VRacks after the first rack, select via the VDrive switch which AES stream to pick off and send to that rack (see diagram to the right). Take advantage of a total system-level solution engineered by the industry leader in amplification, and put the VRack to work for you.

A WARRANTY LIKE NO OTHER

The VRack provides incredible performance, and Crown backs up that performance with our guaranteed warranty – the best in the industry. We have an extensive, thorough list of specifications on our VRack spec sheets, and our guaranteed 5 Year No-Fault Warranty covers every single one of them. Not just the amps – everything.

This means if something isn’t quite right, no matter what it is (aside from normal wear and tear), Crown will fix it. And with our global network of support and service centers, you’ll be back in business fast.
