Crown CDi 4|1200 - 1200W 4-Channel Analog Input 70V/100V Power Amplifier

The Crown CDi 4|1200 is a powerful and versatile 1200W 4-channel analog input power amplifier designed to meet the demands of large installations such as cinemas, houses of worship, hotels, and cruise lines. Equipped with Crown's proprietary DriveCore technology, this amplifier delivers high performance with remarkable efficiency and reliability. The DriveCore design eliminates hundreds of internal components, improving overall consistency and providing superior audio fidelity from a more efficient and compact system. The CDi 4|1200's sleek black finish and flexible configuration make it ideal for a wide range of professional audio applications.

One of the standout features of the CDi 4|1200 is its ability to drive up to 100Vrms speaker loads without the need for external transformers, making it perfect for distributed audio systems in large venues. Each of the four output channels can deliver up to 1200W at 4 ohms, 8 ohms, or for 70V/100V high-impedance loads. The amplifier also supports bridge mono mode, where it can output up to 2400W, providing ample power for more demanding sound systems. This level of flexibility allows the CDi 4|1200 to handle a wide variety of audio configurations with ease, from low-impedance speakers to high-impedance distributed systems.

For easy setup and control, the CDi 4|1200 includes an intuitive front-panel interface that allows users to configure and fine-tune the amplifier directly. In addition, the amplifier features an onboard Digital Signal Processor (DSP) that enables advanced audio customization. The DSP offers features like input routing, 8-band parametric EQ for both input and output, crossovers, input delay (up to 1000ms), output delay (up to 100ms), and LevelMAX limiters to protect speakers and maintain optimal sound quality. The CDi 4|1200 also comes pre-loaded with JBL speaker tunings, making installation and system optimization faster and more straightforward, especially when paired with JBL speakers.

For larger or networked installations, the CDi 4|1200 can be controlled and monitored via Harman's HiQnet Audio Architect software. This allows users to manage multiple amplifiers over a standard TCP/IQ network, providing real-time monitoring and control from any location. The amplifier also features a GPIO/AUX port, which allows for external control of presets, channel muting, power management, and fault monitoring. With these tools, integrators can ensure the system operates seamlessly in a variety of environments.

The CDi 4|1200's robust power handling is supported by a continuously variable-speed forced air cooling system, which directs airflow from front to back, ensuring that the amplifier remains at optimal operating temperatures during extended use. Despite its high power output, the amplifier maintains a low fan noise level (54dBA), making it suitable for installations where noise must be kept to a minimum, such as in cinemas or worship spaces. The amplifier's flexible AC power requirements (100-240V, 50/60Hz) make it compatible with installations worldwide, while the heavy-duty 20A IEC power connector ensures a reliable connection to the mains.

With a total weight of 20.10 lbs and compact dimensions of 19 x 16.01 x 3.5 inches, the Crown CDi 4|1200 easily integrates into standard 19-inch rack systems, optimizing space in professional audio installations. Its high signal-to-noise ratio (>104dB), low total harmonic distortion (0.35%), and damping factor of greater than 1000 ensure that it delivers clean, powerful, and precise sound across all frequencies, making it an excellent choice for demanding applications where audio quality is critical.
