Crown VRack HD4PFX

Description — Crown VRack HD4PFX

The Crown VRack HD4PFX is a professional touring and installation rack frame designed to house three Crown I‑Tech 4x3500HD power amplifiers (sold separately). It’s part of Crown’s VRack family — a rugged, road-ready rack solution that simplifies setup and integration for large live sound systems. The VRack HD4PFX provides power distribution, connectivity, and built-in control infrastructure without the amps included, making it ideal for rental companies and pro audio engineers who want to build or customize their own amplification package.
