Sophisticated Engineering

The Crown® I-Tech HD Series offers amazing power, light weight and ease of use for touring sound applications. Unlike other amplifiers, it includes onboard high-definition DSP, an LCD control screen, 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-Tech Series amplifiers include a number of features which require some explanation before they can be used to their maxi mum advantage.

General Features:
  • 2 Channel I-Tech HD Series Rackmount Stereo High Definition Power Amplifier
  • Global Power Supply with PFC (Power Factor Correction) works anywhere in the world
  • High power density, up to 8000 watts in a 2U chassis
  • Highest output voltage in the industry (200V peak) provides clean transient peaks
  • 3rd-generation patented Class I (BCA®) circuitry couples power efficiently to the load and provides low AC current draw
  • Onboard high-definition DSP with 24-bit, 192 kHz Cirrus Logic SHARC A/D and D/A converters. Advanced IIR filters and linearphase FIR filters
  • Pushbutton presets simplify setup. Custom presets for various loudspeakers can be down loaded
  • AES/EBU digital audio input
  • 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
  • Analog and digital thru connectors
  • 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
  • Light weight 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 volt age, high frequency overloads and internal faults
  • 1-year Manufacturer's warranty

Amplifier Specifications

Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

Frequency Response
The range of frequencies the amplifier will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
Input Sensitivity
This is the input sensitivity of the amplifier.
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
Voltage Gain
This is the voltage gain of the amplifier measured in decibels.
Cooling Options
These are the different cooling systems used in the amplifier to keep it cool.
Inputs
These are the type of input connections that the amplifier has.
Outputs
These are the types of output connections that the amplifier has.
