Crown I-Tech 12000 HD 9000W Amplifier, The Crown® I-Tech 12000HD offers amazing power, light weight and ease of use for touring sound applications. Unlike other amplifiers the IT-12000HD includes onboard high-definition DSP, an LCD control screen, and a built-in network connection. The I-T12000 HD amplifier is a sophisticated piece 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. Please take the time to study the manual so that you can obtain the best possible service from your amplifier.
