Welcome
The VRack is comprised of a rugged touring rack fitted with three Crown IT4X3500HD DriveCore Series amplifiers, a power input panel, and a custom engineered input panel. The input panel is mounted at the top rear and supplies CobraNet(TM) network connections as well as AES3, VDrive and analog XLR connections. The output connections utilize the two NL4 and one NL8 output connector per amplifier. 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 improperly connected; this results in 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 your system to optimal performance, and seamlessly integrates into your system via analog or digital connections.
Each IT4X3500HD has 4 channels, each one capable of 1900 watts into 8 ohms and 2400 watts into 4 ohms. The input panel is engineered by Crown to give the VRack user optimum flexibility when deploying a VRack system for powering VerTec fullsize (VT4889), midsize (VT4888), compact (VT4887A), or subcompact (VT4886) models and their companion subwoofers (VT4880, VT4880A, VT4881A, VT4882, VT4883) as well as the JBL VTX Series and STX Series Loudspeakers.
The input panel buffers AES signals internally, reducing or eliminating the need for additional digital AES3 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.
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.

Choose Input Wire and Connectors
Crown recommends using pre-built or professionally wired, balanced line (two-conductor plus shield), 22-24 gauge cables with 3-pin XLR connectors. Unbalanced line may also be used but may result in noise over long cable runs.
Figure 1 shows connector pin assignments for balanced analog wiring or AES/EBU digital wiring. (The use of standard analog cable with AES/EBU will result in diminished performance) For best results, 110 ohm shielded twisted-pair cable for AES/EBU signals is highly recommended. Figure 2 shows connector pin assignments for unbalanced analog wiring.
NOTE: Custom wiring should only be performed by qualified personnel.

Crown recommends using pre-built or professionally wired, high-quality, two-, four- or eight-conductor, heavy gauge speaker wire and connectors. Use Class 2 output wiring. You may use a 4- or 8-pole Speakon® connector. To prevent the possibility of short circuits, wrap or otherwise insulate exposed loudspeaker cable connectors.
CAUTION – SHOCK HAZARD: Potentially lethal voltages exist at the output connectors when the amplifier is turned on and is passing a signal.
Using the guidelines below, select the appropriate size of wire based on the distance from amplifier to speaker.
Distance Wire Size
up to 25 ft. (up to 7.62 m) 16 AWG
26-40 ft. (7.62-12.2 m) 14 AWG

CAUTION: Never use shielded cable for output wiring.
A. Network Link input. Also distributes VDrive Digital Audio.
B. VDrive Input Switch:
AES XLR to VDrive On-Ramp - When the switch is in this position, the AES3 signal that is connected to AES 1+2 or AES 3+4 XLR is buffered then sent to the amplifiers via VDrive and also buffered and sent to the Network Link Out.
VDrive through Ethernet only - When the switch is in this position, the VDrive signal present on the Network Link Input is buffered and sent to the amplifiers via VDrive and also buffered and sent to the Network Link Out.
No VDrive or AES to Amps - When the switch is in this position, no AES3 signal is distributed from the input panel to the amplifiers. This mode should be used when patching AES3 signal directly to the amplifiers when the input panel is bypassed.
C. AES3 Inputs - Sends AES3 signal to the amplifiers. When VDrive switch is set to "AES XLR to VDrive On-Ramp" this input AES3 signal is sent to the 3 amplifiers with the VRack and sent to Network out VDrive.
D. AES3 Link Outputs - When power is applied to the rack, the AES3 signal is taken from the input, buffered, then sent to this link output connection. If the rack is not powered on, AES3 signal is still sent from the input connection but it is not buffered.
E. Analog Inputs - Analog 1 of this input panel is sent to each IT4x3500HD's analog 1 input. Analog 2 of this input panel is sent to each IT4x3500HD's Analog 3 input. This is set up this way so that when the rack is configured to bi-amp mode, the amplifiers see Analog 1 and 3 inputs.
F. Analog outputs - These outputs are in parallel with the analog inputs. There are no active or passive circuitry between the input and output connections.
G. VDrive Output Switch - This switch selects whether or not the buffered AES3 Signal based on the VDrive input switch selection is sent out the Network Link Output. When in "OFF" Mode, network communication is still maintained regardless of the switch position.
H. Network Link Output - Also distributes VDrive digital audio if the VDrive Output switch is enabled.
***NOTE – All AES 3 signals are sent from the input panel to the Ampliers via VDrive. Therefore, any time you use the VRack's input panel
for AES3 distribution to the amplifiers, the IT4x3500HD amplifier must be set to VDrive AES mode. (See Page 16 for more information)

VDrive is a digital AES3 transport mechanism that combines a standard 10/100MB network connection with AES3 signals. VDrive employs the unused pins of a 10/100MB network to transport AES3 digital audio signals. As indicated in the chart above, one is able to transmit 4 channels of digital audio using a standard CAT5 cable.
VDrive is distributed from the VRack4X3500HD input panel to the individual IT4x3500HD amplifiers via VDrive. The AES3 signal that utilizes the input panel’s AES XLR connectors as an input is buffered and then sent to the amplifiers via VDrive. If you are using the VDrive input on the input panel, the AES signal over the Ethernet connection is buffered and then sent to the individual IT4X3500HD amplifiers via VDrive. The VDrive output is also buffered.
If you are using the AES3 XLR or VDrive inputs on the VRack4X3500HD input panel, it is very important you save your preset or device files with the VDrive enabled.

HiQnet Software
The Crown VRack has a unique advantage when used with Harman's HiQnet System Architect software. The software is able to literally 'see' that your iTech4x3500HD amplifiers are in a rack, and specifically they're in a VRack. You get specific advantages in speeding up deployment, programming, tuning, and monitoring of a VRack powered system.
In addition, the user can combine the presets in all 3 VRack ampmlifiers into a single 'VRack Preset'. This is done by loading the individual preset into each amplifier, and then using the VRack control panels' 'Preset' tab to save each individual preset into the same preset memory location on each amp. Now with a single click, an 'entire rack' setting can be recalled. For most sound companies this means that with an initial investment of some time in the shop, single-click 'entire rack' settings can be configured for most of the PA in inventory, eliminating the need to program and recall individual presets in the field.

Designing and Recalling Presets
The VRack Preset Tab recalls the same preset numbers on all amplifiers; therefore, it is recommended you save system-specific presets by preset numbers.
Below is an example of how to set up a 3-Way VTX V25 preset.
Step 1: Select output mode for the application. This example is 3-way, done using OEM JBL Pro factory presets. (Available in c:\…\My Documents\HPro… or online at www.jblpro.com)
Step 2: Open the device panel for the amplifier and load bandpass presets based on above Output Operation Mode.
Step 3: Open the device panel for the amplifier and load bandpass presets based on above Output Operation Mode.
Step 4: Store presets as VTX V25 X ST VRACK, in an empty memory location in all 3 amplifiers.
Step 5: Repeat as needed for 60 and 80 crossovers.
Step 6: Recalling preset will reconfigure VRack amplifiers for desired operation.
