Crown I-Tech 12000HD - 4500W 2-Channel at 4-Ohm Power Amplifier

The Crown I-Tech 12000HD is a cutting-edge, high-performance 2-channel power amplifier designed for professional touring sound applications, offering 4500W per channel at 4 ohms. Renowned for its powerful output, lightweight design, and advanced technology, this amplifier is ideal for large-scale live sound environments where power, reliability, and ease of use are paramount. The I-Tech 12000HD is built to meet the demands of modern touring professionals, with a host of features that make setup, operation, and system integration seamless and efficient.

At the heart of the I-Tech 12000HD is Crown's patented BSS OMNIDRIVEHD DSP processing engine, which delivers unparalleled audio clarity and precision. With four times the processing power of previous models, this advanced DSP engine utilizes Linear Phase FIR filters and LevelMAX limiters to provide superior sound quality, ensuring that audio signals are processed with unmatched clarity and fidelity. This amplifier is designed to handle the most demanding audio environments, producing clean, powerful sound across a wide range of frequencies.

Featuring an onboard high-definition DSP system with 24-bit, 192 kHz Cirrus Logic SHARC A/D and D/A converters, the I-Tech 12000HD offers advanced signal processing capabilities. It includes a comprehensive suite of IIR filters, linear-phase FIR filters, and push-button presets that simplify setup and allow for easy configuration of custom loudspeaker presets. These presets can be downloaded from Crown's extensive library, or users can create their own to match specific speaker configurations and venue requirements.

One of the most distinctive aspects of the I-Tech 12000HD is its robust power supply, equipped with Power Factor Correction (PFC) technology. This global power supply can operate efficiently anywhere in the world, ensuring consistent performance across different voltage environments. The PFC reduces current draw and increases efficiency, which is particularly beneficial in high-demand touring applications where power availability can vary. The I-Tech 12000HD also delivers the highest output voltage in the industry, with a peak of 200V, ensuring clean transient peaks and powerful, distortion-free audio.

The amplifier is housed in a 2U aluminum chassis, making it both lightweight and durable. At only 28 lbs, the I-Tech 12000HD is easy to transport and install, which is crucial for mobile setups and touring sound systems. Its compact size allows for high power density, fitting 8000 watts of power into a small form factor without compromising performance. This is made possible by Crown's third-generation Class I (BCA) circuitry, which efficiently couples power to the load while minimizing AC current draw, ensuring the amplifier runs cool and performs consistently even under demanding conditions.

The front panel of the I-Tech 12000HD features an intuitive LCD control screen that allows users to adjust amplifier attenuation, mute channels, configure settings, monitor errors, and recall DSP presets. This easy-to-use interface simplifies the process of setting up the amplifier for different applications and provides real-time feedback for monitoring system performance. Additionally, the amplifier includes a USB port on the front panel for easy transfer of presets, enabling fast updates and customization on the go.

The I-Tech 12000HD offers a comprehensive array of diagnostic indicators, including Power, Data, Ready, Signal, Clip, Thermal, and Fault indicators for each channel. These indicators ensure that system operators have immediate, accurate feedback on the amplifier's performance, making it easy to identify and troubleshoot any potential issues. The AC mains indicator built into the power switch glows green when AC power is present, providing clear confirmation of power status.

Connectivity and system integration are key features of the I-Tech 12000HD. It includes both analog and digital AES/EBU inputs, as well as through connectors for flexible signal routing. For networked audio, the I-Tech 12000HD is equipped with an EtherCon Ethernet connector, allowing for control via Harman's HiQnet protocol and digital audio transport through CobraNet. This "Single Plug" connection simplifies system wiring, as both control and digital audio can be transmitted through a single CAT 5 cable, streamlining installation and reducing cable clutter.

Thermal management is another area where the I-Tech 12000HD excels. It features a thermal management controller and two discrete thermal zones, with variable-speed fans and forced-air cooling. This ensures the amplifier operates within safe temperature ranges, even under heavy use, protecting it from overheating and extending its operational lifespan. Advanced protection circuitry safeguards the amplifier and connected loads from shorted outputs, DC, mismatched loads, overheating, under/over voltage, and high-frequency overloads.

The Crown I-Tech 12000HD is engineered for high-performance applications where power, sound quality, and reliability are critical. With its advanced DSP, powerful amplification, and easy-to-use control features, it is the amplifier of choice for professional touring sound systems and large-scale live events.
