BSS OMNIDRIVEHD Processing

At the heart of the I-Tech 9000HD is the BSS OMNIDRIVEHD processing engine. It supports both IIR and linear-phase FIR filters and delivers high-definition signal processing through 24-bit/192 kHz Cirrus Logic SHARC A/D and D/A converters.

LevelMAX Limiting

LevelMAX peak-voltage and RMS-power limiters communicate with each other to provide smooth and accurate loudspeaker protection while preserving overall sound quality. This coordinated limiting helps maintain consistent performance during demanding high-output operation.

High-Efficiency Class-I Amplification

Crown's 6th-generation patented Class-I BCA circuitry efficiently couples amplifier power to the load while helping reduce AC current draw. Full power-supply voltage remains available for instantaneous power demand, while increased energy reserves support clean transient peaks.

Flexible System Connectivity

The I-Tech 9000HD supports analog, AES/EBU, CobraNet, HiQnet, and Ethernet connectivity. Inputs can be routed to available outputs as required, giving system designers and touring engineers extensive flexibility when integrating the amplifier into complex audio systems.

Advanced Monitoring and Control

SLM Sweep Load Monitoring provides system-level diagnostics, while true tachometer feedback monitors fan operation for precise thermal management and fan-fault protection. A front-panel USB connector allows presets to be transferred between the amplifier's DSP and a USB drive, while user-definable front-panel security helps prevent unauthorized changes.
