Crown DCi 4|1250N - 1250W 4-Channel at 4-Ohm 70V/100V Analog Power Amplifier with BLU Link

The Crown DCi 4|1250N is a high-performance 4-channel power amplifier designed for demanding professional audio installations. Delivering 1250 watts per channel at 4 ohms or 70V/100V, this amplifier is part of the renowned DriveCore Install series, offering superior flexibility and reliability for installed sound applications. Engineered with Crown's patented DriveCore technology, the DCi 4|1250N combines cutting-edge Class D amplifier topologies with advanced power management, making it an ideal solution for a wide range of audio installations, including large-scale venues, theaters, and corporate environments.

One of the standout features of the DCi 4|1250N is its integration with Harman's BLU Link technology, which enables seamless digital audio routing over a fault-tolerant, low-latency bus. With the ability to route up to 256 channels of digital audio using standard Category 5e cabling, BLU Link provides unparalleled routing flexibility for complex audio systems. This amplifier also supports network control and monitoring via HiQnet Audio Architect, allowing system integrators to monitor performance, configure settings, and receive comprehensive error reporting remotely over a TCP/IP network, ensuring streamlined management and troubleshooting.

The amplifier's advanced Digital Signal Processing (DSP) capabilities include input and output EQ filters, crossovers, input/output delay, and LevelMAX limiters, all of which provide integrators with the ability to fine-tune the audio system for optimal sound quality. The DSP suite also includes an input compressor, signal generator, and programmable general-purpose input/output (GPIO) ports, further expanding the amplifier's functionality and customization potential. The GPIO ports allow for control over various amplifier functions such as muting, preset recall, and fault monitoring, making the DCi 4|1250N an extremely versatile amplifier for installed sound systems.

Crown's proprietary DriveCore technology powers the DCi 4|1250N, integrating hundreds of discrete circuits into a single chip for improved efficiency and reduced power consumption. The amplifier is designed to drive both low-impedance (2/4/8/16 ohms) and high-impedance (70V/100V) speaker loads, with each channel individually configurable for constant voltage or direct drive operation. This eliminates the need for external transformers, ensuring higher audio fidelity while reducing wiring costs and complexity.

Built with system reliability in mind, the DCi 4|1250N features advanced protection circuitry to safeguard both the amplifier and the connected speakers. Protection mechanisms include thermal overload protection, short circuit protection, DC fault protection, and safeguards against mismatched loads. Additionally, the Thermal Limiting Control (TLC) system intelligently reduces gain to prevent overheating, ensuring continuous, reliable operation even under demanding conditions.

Energy efficiency is another key feature of the DCi 4|1250N, thanks to its Power Factor Correction (PFC) universal power supply. This advanced power supply design ensures stable operation across varying voltage conditions, making the amplifier suitable for global installations. The PFC supply guarantees minimum rated power delivery while significantly reducing power consumption, making the DCi 4|1250N an environmentally friendly choice for large-scale installations. An auto-standby mode further enhances energy savings by powering down the amplifier after 30 minutes of inactivity, reducing power consumption to less than 1W during standby.

The amplifier is housed in a 2U rack-mountable chassis, offering true rack density and a compact form factor for space-efficient installations. Weighing just 30 lbs, the DCi 4|1250N is easy to handle and integrates seamlessly into audio racks. A revolutionary front-to-back forced air cooling system, equipped with variable speed fans, ensures efficient heat dissipation while minimizing operational noise, making the amplifier ideal for installations where quiet operation is essential.

The Crown DCi 4|1250N is a robust, high-power amplifier designed for integrators who demand versatility, reliability, and cutting-edge technology for their audio installations. With BLU Link compatibility, advanced DSP, and network control capabilities, this amplifier offers everything needed for seamless, high-performance audio in professional environments.
