Setup Setup Suspension Hardware Inspection & Maintenance Type of Connectors to Use with VRack Suspension systems are comprised of mechanical devices and, as such, they require regular inspection and routine maintenance to ensure proper function ability. The Crown VRack must be inspected for fatigue at least annually.
Setup Setup Cee-Form U.S. Operation Power Supply Schematic Cee-Form 120VAC Operation Switch Position “Input Pin/Sleeve, Output US/120 EU/240” provides 120VAC operation from the Cee-Form pin and sleeve connector. From an external power distribution system, send 3 phase 120VAC power to the X, Y, and Z pin of the Cee-Form connector and the VRack will operate in 120VAC operation mode. Each I-Tech HD amplifier will see a dedicated line-to-neutral connection as well as a ground.
I-Tech HD Amplifier Specifications Front Panel Features I-Tech HD Amplifier Specifications The Crown® I-Tech 4X3500HD DriveCore Series offers amazing power, light weight and ease of use for tour sound applications. Unlike other amplifiers, it includes onboard high-definition DSP, a 4.3” LCD TFT Capacitive Touchscreen, and a built-in network connection. Three IT4x3500HD Amplifiers Modern power amplifiers are sophisticated pieces of engineering capable of producing extremely high power levels.
Setup Input Panel Choose Input Wire and Connectors B 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.

HiQnet™ Software 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.
HiQnet™ Software HiQnet™ Software Input Tab Select the desired input mode you would like from the drop down menu. After selecting the desired input mode, a visual representation of how to connect the VRack input panel will be shown.
