1 Welcome

The Crown® I-Tech Series offers amazing power, light weight and ease of use for touring sound applications. Unlike other amplifiers, it includes onboard 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 expla- nation before they can be used to their maxi- mum advantage.

Please take the time to study this manual so that you can obtain the best possible service from your amplifier.

1.1 Features

•Global Power Supply with PFC (Power Fac- tor 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®) cir- cuitry couples power efficiently to the load and provides low AC current draw.

•Onboard DSP with 24-bit, 96 kHz Cirrus Logic A/D and D/A converters.

•Pushbutton presets simplify setup. Custom presets for various loudspeakers can be down- loaded.

•AES/EBU digital audio input. Ethernet con- nector accepts RJ-45 connector for HiQnet™ or TCP/IQ networking.

•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, Bridge, along with Ready, Signal, Clip, Thermal and Fault for each channel.

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

•Light weight due to aluminum chassis, spe- cial internal construction and switching power supply.

•Thermal management controller and two dis- crete 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.

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