The Crown ® I-Tech HD Series offers amazing power, light weight and ease of use for tour 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-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 HD manual.
