Operation Manual

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.

Modern power amplifiers are sophisticated pieces of engineering capable of producing extremely high power levels. They 

must be treated with respect and correctly installed if they are to provide the many years of reliable service for which they were 

designed.

In addition, I-TechHD Series amplifiers include a number of features which require some explanation before they can be used 

to their maximum advantage. Please take the time to study this manual so that you can obtain the best possible service from 

your amplifier.

For more information please refer to I-Tech 4X3500 HD manual.

Features:

• Global Power Supply with PFC (Power Factor Correction) works anywhere in the world

• High power density, up to 12,000 watts in a 2U chassis

• Output voltage of 185Vpk provides clean transient peaks

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

• Onboard high-definition Analog Devices Sharc DSP with 24-bit, 192 kHz SHARC A/D and D/A converters; advanced IIR 

filters and linear phase FIR filters

• Pushbutton presets simplify setup; custom presets for various loudspeakers can be downloaded or created

• AES3 digital audio input with VDrive

• EtherCon® Ethernet connector for HiQnet™ control or CobraNet™ digital audio transport – this “Single Plug” connection 

allows HiQnet™ protocol and CobraNet™ digital audio through the same CAT 5 cable

• LCD Control Screen is used to adjust the amplifier’s attenuation and muting, configure the amp, set up and view error 

monitoring, and recall DSP presets to reconfigure the amp for various applications

• Comprehensive array of indicators provide accurate diagnostics: Power, Data, along with Ready, Signal, Clip, Thermal and 

Fault for each channel

• AC mains indicator in power switch glows green when AC power is present

• Front-panel USB connector accepts a USB drive to transfer presets from the drive to the amplifier DSP, and vice versa

• Lightweight due to aluminum chassis, special internal construction and switching power supply

• Thermal management controller and two discrete thermal zones with variable-speed fans, forced-air cooling

• Advanced protection circuitry guards against: shorted outputs, DC, mismatched loads, general overheating, under/over 

voltage, high-frequency overloads and internal faults

• Five-Year, No-Fault, Fully Transferable Warranty completely protects your investment and guarantees its specifications
