Crown I-Tech Series Amplifers

The 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.

Pushbutton 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 status information.
