Inside and out, the I-Tech HD is one of the most technologically advanced professional touring amplifiers on the market today. Building on the decades of innovation, invention, and insight Crown is known for, the I-Tech HD features five new patents – three on the power supply alone – giving you an amp that goes well beyond the expected.  At the heart of the new I-Tech HD is the BSS OMNIDRIVEHD™ processing engine. Four times faster than its predecessor and featuring Linear Phase FIR filters and LevelMAX™ limiters, OMNIDRIVEHD provides unmatched clarity and sonically pure signal processing.

Features

Innovation

• BSS OMNIDRIVEHD™ DSP processing with IIR filters and linear phase FIR filters

• Covered by five patents

• Fan has true tachometer feedback for fan fault protection and precise control over thermal performance, so the amp runs longer and harder than the competition

• Includes SLM (Sweep Load Monitoring) with system-level diagnostics

Performance

• Ultra smooth processing by onboard high-definition BSS OMNIDRIVEHD DSP with 24-bit, 192kHz Cirrus Logic SHARC A/D and D/A converters

• LevelMAX™ peak voltage and RMS power limiters communicate with each other, resulting in smooth and accurate response, better sound

• True Ethernet backbone – fast, reliable and scalable

• High common-mode rejection eliminates hum and RFI on input cables

• 6th-generation patented Class-I (BCA®) circuitry couples power efficiently to the load and provides low AC current draw

Versatility

• Global Power Supply; universal AC input accepts100-240VAC, 50/60Hz (±15%)

• Front-panel USB connector transfers presets to/from a USB drive to the amp’s DSP

• New software interface based on customer feedback manages presets, provides easier system-level changes, and includes a configuration wizard

• The only product available with analog, AES/EBU, CobraNet®, HiQnet™and Ethernet connectivity

• User -definable front panel security feature

• The only tour sound amplifier that provides inputs routable to any output (analog, AES, or CobraNet)

Power

• Professional-grade connectors for all inputs and outputs

• Full power-supply voltage is always available, allowing instantaneous power on demand

• Quality-graded components let you safely drive the amplifier harder

• More total capacitance provides tremendous energy reserves for power bursts

• 200Vrms peak output voltage provides clean transient peaks
