Crown IT8000 iTech Power Amplifier
The Crown I-Tech Series offers amazing power, light weight and ease of use for touring sound and installed sound applications. Onboard DSP provides a wide array of signal processing, greatly reducing the need for rack components and rack wiring. Onboard DSP features 24-bit, 96 kHz A/D and D/A converters. I-Tech amplifiers are compatible with the IQ Network and TCP/IQ networking. Digital audio and IQ control signals connect to the amp via a single CobraNet cable in optional CN models, coming soon. Pushbutton DSP presets simplify the setup for various loudspeaker arrays. The Global Power Supply works anywhere in the world, and offers PFC (Power Factor Correction). It is a switching power supply for reduced weight. 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 status information.
