Crown VRACKHD4FX Complete HD4 Vrack

Crown VRACKHD4FX Complete HD4 Vrack

The Crown VRACKHD4FX is a fully integrated rackmount amplification and power distribution system engineered for recording studios, live rooms, and post-production facilities requiring transparent, high-headroom audio amplification across multiple channels. This compact yet powerful unit consolidates three Crown 3500HD amplifiers with integrated I/O management, eliminating the need for separate amp units and external switching gear. Built for studio engineers, installed systems, and rental facilities, the Vrack delivers professional-grade amplification in a single 4U footprint, streamlining session workflow and reducing cable clutter in the machine room.

Recording & Monitoring Performance

The system achieves a signal-to-noise ratio of ≥108dB and total harmonic distortion of 0.35%, ensuring pristine audio reproduction during tracking and monitoring sessions at extended operating levels. With a damping factor exceeding 5000, the amplifiers maintain tight control over speaker loads across the full frequency spectrum, delivering the accuracy required for critical listening, mastering reference, and live-room recording applications.

Connectivity & Studio Integration

Four discrete input and output pairs support analog, AES 3 digital, VDrive, and CobraNet protocols, allowing seamless integration into networked studio systems or traditional analog console chains. The HiQnet Performance Manager™ software provides comprehensive control and real-time monitoring of all amplifier parameters from the control room, while adjustable sensitivity from 1.28Vrms to 8Vrms in 0.1dB increments accommodates virtually any source impedance, console output level, or interface gain structure used in modern production environments.
