Crown International has announced the all new I-Tech Series, their new flagship amplifier series for the touring and corporate PA markets.

I-Tech packs a lot of power into a small, lightweight package, with all models being 2RU and weighing less than 28 lbs. (12.7 kg.). I-Tech is built for the road, with a rugged chassis designed to withstand abuse. I-Tech features Crown's Class-I switching output design to deliver massive amounts of power while generating a fraction of the heat of conventional designs. Crown's global regulated power supply delivers full power regardless of AC mains voltage: from 120 to 277 volts, and from 50 to 60 Hz. Power Factor Correction (PFC) allows I-Tech to draw current from the mains more efficiently, providing more power from a single 20 amp breaker. The Class-I output and advanced power supply combine to allow I-Tech to provide the highest output voltage available, for a clearly audible difference when driving today's high-performance loudspeakers.

A front panel work surface with LCD display provides fast and easy menu-based system setup and full amplifier diagnostics. AES/EBU digital audio inputs are standard, along with balanced analog XLR inputs and passive-through outputs. Crown plans to soon announce availability of integrated CobraNet digital audio inputs as an option. Integrated studio-grade DSP with 24 bit / 96kHz converters allow custom settings and factory-designed tunings to be easily loaded and recalled via onboard presets.

I-Tech amplifiers connect directly to IQ Networks, providing Crown's IQ control over industry-standard Ethernet network technology. Using mature, off-the-shelf networking technology, Crown's TCP/IQ protocol provides inexpensive network operation. By connecting I-Tech to an IQ Network and running the free IQwic software application, all amplifier controls can be accessed, and vital amplifier operating parameters monitored, from a remote location. Multiple levels of security are available to prevent unauthorized adjustment of system settings.

Minimum guaranteed power ratings are as follows: Power per channel with both channels driven:

I-T4000: 1,800W at 2 Ohms; 2,000W at 4 Ohms; 1,250W at 8 Ohms. I-T6000: 2,500W at 2 Ohms; 3,000W at 4 Ohms; 1,500W at 8 Ohms. I-T8000: 3,500W at 2 Ohms; 4,000W at 4 Ohms; 2,100W at 8 Ohms.

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. All models are compatible with the HiQnet Network and TCP/IQ networking. Digital audio and HiQnet/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.
