The VRack is comprised of a rugged touring rack fitted with three Crown IT12000HD amplifiers, a power input panel, and
custom engineered input and output panels. The input panel is mounted at the top rear and supplies CobraNet(TM) network
connections as well as AES/EBU and analog XLR connections. The output panel on the bottom rear of the rack offers 12
Speakon outputs: 3 x 2-way NL4 outputs, 6 x 1-way NL4 outputs, and 3 x 3-way NL8 outputs. The front-mounted power panel
includes a 5-pin Hubbell Twist-Lock connector and a 5-pin CEE-Form connector.
Because the VRack is supplied with all components installed and internally connected, there is no need for laborious rack
building; no chance that a component might be impropery connected; and a dramatically lower chance of connection failure.
The VRack is best thought of not as just an amp rack, but as a building block for your system. Every time you add 1 VRack
into a system, you are adding 1 block that powers a proper 3:2 ratio of tops and subs for optimal performance, and seamlessly
integrates into your system via analog or digital connections.
Each IT12000HD has 2 channels, each one capable of 2100 watts into 8 ohms and 4500 watts into 4 ohms. The input and
output panels are both engineered by Crown to give the VRack user optimum flexibility when deploying a VRack system
for powering VerTec fullsize (VT4889), midsize (VT4888), compact (VT4887A), subcompact (VT4886) models, companion
subwoofers (VT4880, VT4880A, VT4881A, VT4882, VT4883), and the latest JBL VTX and STX800 models.
The input panel automatically buffers AES signals, reducing or eliminating the need for digital distribution amplifiers. Through
VDrive (pg.27), the user is able to run Ethernet control and AES digital audio over a single Cat5 which jumps from rack to rack.
The output panel is designed to offer easy configuration for a variety of PA systems. It gives the ability to run tops off NL8
and subs off NL4s, monitors or fills off 2-way NL4 outputs, or for VT4887A/VT4881A and VT4886/VT4883 systems, an entire
circuit of tops+subs off a single NL8. See pg.28 for output panel and a summary of wiring configurations.
VRack is manufactured and tested to a single meticulous standard, and then shipped around the world. This means that any
time you supply or cross-rent a VRack it is the same as every other VRack in the world.
