||Crown I-Tech Series Amplifiers
Crown I-Tech Series amplifiers offer amazing power in a light weight chassis designed
ease of use in touring and installed sound applications.
The onboard DSP features
24-bit, 96 kHz A/D and D/A converters to provide a wide range of signal processing
capabilities, greatly reducing the need for additional rack components and wiring.
All models are compatible with the HiQnet Network and TCP/IQ networking.
DSP presets simplify the setup for various loudspeaker arrays. The universal switching
power supply reduces weight, offers Power Factor Correction and works anywhere
in the world. I-Tech amplifiers have the highest output voltage in the industry
(200V peak), which provides clean transient peaks. The 3rd-generation patented
Class-I (BCA®) circuitry couples power efficiently to the load and allows low
AC current drain. A front-panel control screen shows advanced diagnostics and
