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

The Crown CDi 4|1200BL is a high-performance 4-channel analog input amplifier with BLU link, delivering 1200W per channel, specifically designed for large-scale installations such as cinemas, houses of worship, hotels, cruise lines, and other similar venues. Part of Crown's CDi DriveCore Series, this amplifier merges powerful audio capabilities with a rich feature set and cost-efficiency, making it the ideal solution for demanding professional audio installations. The CDi 4|1200BL leverages Crown's proprietary DriveCore technology, which replaces hundreds of components, improving reliability and delivering exceptional audio fidelity from an efficient, lightweight design.

One of the key features of the CDi 4|1200BL is its BLU link functionality, enabling the amplifier to send and receive channels over HARMAN's 256-channel fault-tolerant digital audio bus, making it ideal for networked audio installations. This feature, combined with the amplifier's support for driving high-impedance 70V and 100V speaker loads directly (without requiring a transformer), makes it suitable for a wide range of professional applications, including large distributed audio systems.

The CDi 4|1200BL amplifier is equipped with network control and monitoring through Harman's HiQnet Audio Architect software, providing seamless integration into networked systems for centralized control and monitoring. This enables audio engineers to configure and manage the amplifier from a remote location via a standard TCP/IQ network, simplifying installation and maintenance in large venues.

The CDi 4|1200BL features an advanced onboard Digital Signal Processor (DSP) with powerful customization options. The DSP includes integrated features such as input routing, input delay (up to 1000ms), 8-band input and output parametric EQs, crossovers, output delay (up to 100ms), and LevelMAX limiting for maximum speaker protection. These DSP features ensure that audio signals are precisely controlled and optimized, catering to the specific needs of the venue and audio system.

With its dual-mode power output, the CDi 4|1200BL delivers 1200W per channel at 4 and 8 ohms, as well as 70Vrms and 100Vrms configurations, making it flexible for a variety of speaker setups. In bridge mono mode, the amplifier provides up to 2400W of power, making it suitable for more demanding applications where higher power output is needed. The amplifier is ideal for powering multiple speakers in large installations, whether distributed audio systems or high-power setups.

The front-panel interface of the CDi 4|1200BL allows users to fully configure the amplifier on-site without the need for additional software. This user-friendly interface provides quick and intuitive access to all key amplifier settings, streamlining the setup process and making real-time adjustments easy. The GPIO/AUX port adds further flexibility, allowing users to recall presets, mute channels, monitor faults, and control the power state of the amplifier remotely, making it highly adaptable to various operational needs.

For quicker installations, the CDi 4|1200BL comes pre-loaded with JBL speaker tunings, ensuring that JBL speakers are optimized for performance from the outset. This feature saves installation time and ensures superior sound quality with minimal effort. Additionally, the amplifier's direct drive 70V/100V output eliminates the need for transformers, simplifying the installation process and reducing system complexity.

Cooling is handled via a continuously variable speed forced-air system, with front-to-back airflow, ensuring that the amplifier operates within safe temperature limits even under demanding conditions. Despite its high power output, the amplifier operates quietly, with a maximum fan noise level of just 54dBA, making it suitable for environments where low noise levels are important.

The Crown CDi 4|1200BL amplifier is built with durability and reliability in mind, featuring robust protection mechanisms against component variability, voltage spikes, and thermal overloads. The amplifier's universal power supply (100-240V, 50/60Hz) makes it compatible with installations worldwide. Its sleek, black-finished chassis is designed for rack mounting, with dimensions of 19 x 16.01 x 3.5 inches and a weight of 20.10 lbs, making it easy to integrate into standard 19-inch equipment racks.
