Crown DCi 4|1250DA - 1250W 4-Channel at 4-Ohm 70V/100V Analog Power Amplifier with Dante

The Crown DCi 4|1250DA is a 4-channel, 1250W per channel analog power amplifier with Dante and AES67 networked audio capabilities, designed for professional installations requiring high-performance and flexible audio distribution. With the advanced features of Crown's DriveCore Install (DCi) series, the DCi 4|1250DA offers powerful, reliable, and energy-efficient operation, making it ideal for large installations like cinemas, houses of worship, hotels, and other commercial spaces. The addition of Dante network audio support makes it perfect for projects that require seamless integration into modern audio-over-IP environments.

This amplifier is built around Crown's exclusive, patented DriveCore technology, which integrates hundreds of discrete circuits into a single chip. This results in better performance, higher reliability, and reduced power consumption, making the amplifier exceptionally energy-efficient and ideal for long-term installations. It also features True Rack Density, with power outputs of 1250W per channel across four channels, all housed in a compact 2U rack-mountable chassis, allowing integrators to maximize output while saving valuable rack space.

The DCi 4|1250DA is designed for use with low-Z (2, 4, 8, 16 ohms) and high-Z (70V, 100V) speaker systems, providing flexibility for a wide range of applications. Each channel can be individually configured for low-Z or high-Z operation, and the amplifier can drive constant voltage speaker systems without requiring step-up transformers, resulting in higher audio quality and reduced installation costs. Additionally, the amplifier's advanced DSP (Digital Signal Processing) capabilities allow for detailed audio customization with features like LevelMAX limiters, input/output EQ, input/output delay, signal generator, and crossovers, ensuring optimal performance for any installation.

One of the standout features of the DCi 4|1250DA is its integrated Dante and AES67 networked audio capabilities, which allow it to receive and transmit high-quality digital audio over a standard Ethernet network. This simplifies installation and reduces the need for additional cabling by enabling direct network connections for audio transport. The amplifier supports Dante Domain Manager, making it ideal for installations where secure, scalable, and flexible audio networking is required.

The amplifier is compatible with Harman's HiQnet Audio Architect software, allowing for comprehensive network control and monitoring via TCP/IP. This includes real-time load monitoring, error reporting, pilot tone monitoring, and control over GPIO ports for external system integration. Additionally, it supports remote standby, which can be activated via the AUX port, and features power-saving modes that reduce power consumption to less than 1W when in sleep mode. Adjustable auto-standby settings ensure the amplifier conserves energy when not in use, contributing to lower operational costs.

In terms of protection, the DCi 4|1250DA is equipped with Crown's advanced protection circuitry, which safeguards both the amplifier and connected speakers from potential damage due to short circuits, DC faults, mismatched loads, overheating, and high-frequency overloads. The TLC (Total Linear Control) system ensures that the amplifier remains operational even under extreme conditions by intelligently applying gain reduction when necessary, preventing thermal shutdowns.

The amplifier's universal PFC (Power Factor Correction) power supply is designed to deliver maximum efficiency, providing guaranteed power output even in environments with fluctuating voltage. This feature ensures consistent performance in installations worldwide, as the amplifier accepts a wide range of input voltages (100-240V, 50/60Hz). The cooling system uses variable-speed forced-air cooling, ensuring efficient airflow and maintaining low operating temperatures. The system is designed to target airflow precisely where needed, reducing fan noise to a maximum of 47 dB, making the amplifier suitable for environments requiring quiet operation.

Built for longevity and environmental sustainability, the DCi 4|1250DA complies with Harman's GreenEdge initiative, which focuses on environmentally friendly design, manufacturing, and packaging practices. This amplifier is designed to be as efficient and eco-friendly as possible, making it a responsible choice for modern installations.

In summary, the Crown DCi 4|1250DA is a robust, feature-packed power amplifier that delivers 1250W of output across four channels, supports both low- and high-impedance speaker configurations, and integrates seamlessly with Dante and AES67 networked audio systems. With its advanced DSP, network control, and protection features, it offers unmatched flexibility and reliability for large-scale, professional audio installations.
