ELKHART, Indiana — HARMAN’s Crown Audio
today announced it is adding to its popular VRACK complete amplifier management
solutions with the introduction of its VRACK 4x3500HD. The new version
incorporates three of Crown’s flagship I-Tech 4x3500HD DriveCore™ Series
4-channel power amplifiers in a single road-ready plug-and-play rack, providing
a versatile, turnkey multichannel amplifier solution for tour, rental and
installed sound applications.
Designed to work hand in
hand with JBL VTX and VerTec Series models
with upcoming support planned for JBL VRX and STX models, the VRACK 4x3500HD
includes three built-in Crown I-Tech HD Series 4x3500 DriveCore power amps, analog and digital
connections and a globally universal power distribution system that can be set
to meet US and international power standards. All the components are housed in
a wheeled rack with a captive suspension system that enables it to be flown in
the same manner as a line array loudspeaker system. Multiple VRACKs can be
linked together for integrated operation in larger systems.
“Since its introduction our
VRACK concept has been embraced by live sound and event providers for its
plug-and-play operation, easy transportability and flexible configuration
options,” said Brian Pickowitz, Business Segment Manager, Crown Audio. “The
VRACK 4x3500HD builds on this concept with a full 12 channels of high-power
amplification and greatly expanded connectivity features, giving users a
powerful and versatile multichannel amplifier management solution.”
“VRACK is an
integral part of our turnkey system package for JBL VTX and VERTEC”, adds Paul
Bauman, Senior Manager, Tour Sound, JBL Professional. “Based on field testing
to date, we’ve been extremely pleased with IT4x3500HD performance and
VRACK4x3500HD provides the amp rack equivalent of the optimized power density
philosophy that was adopted for the VTX V25 loudspeaker itself – lots of horsepower
in a compact, tightly-integrated package.”
The I-Tech 4x3500HD amplifiers feature
a 4.3-inch front-panel LCD touchscreen that provides amplifier monitoring and
access to key functions with color-keyed visuals. Each amplifier offers an
extensive complement of inputs and outputs including four analog inputs, four
AES3 digital inputs and four AES inputs over VDrive and the ability to select
four CobraNet® inputs. The amplifiers also include SpeakON or banana
plug speaker connectors.
The VRACK 4x3500HD utilizes HARMAN
HiQnet System Architect™ 3.2 control functionality and Version 5 DSP preset
support for JBL Professional’s new VTX Series V25 plus VERTEC Series line array loudspeakers. System
Architect provides control through monitoring and adjustment on a rack-by-rack
basis and the ability to make changes to all three amps in the VRack through a
single interface. The VRACK 4x3500HD is also compatible with JBL HiQnet
Performance Manager™ sound reinforcement system design software for enhanced
control and monitoring capabilities.
The I-Tech 4x3500HD amplifiers deliver
1,900 watts per channel into eight ohms, 2,400 watts per channel into four ohms
and 4,200 watts into four ohms bridged. The amplifiers provide extensive DSP
sound-tailoring capability and incorporate Crown’s exclusive linear phase FIR
and IIR filters to provide optimized loudspeaker crossover points with improved
midrange clarity and off-axis response. The amplifiers’ USB port enables users
to load preset amplifier settings or device files and update firmware.
The Crown VRACK 4x3500HD amplifier management solution is now shipping.
