Crown DCi 4|600DA - 600W 4-Channel at 4-Ohm 70V/100V Analog Power Amplifier with Dante

The Crown DCi 4|600DA is a high-performance 4-channel analog power amplifier delivering 600W per channel at 4 ohms with integrated Dante and AES67 networked audio capabilities. Designed for medium to large installed sound applications such as theaters, houses of worship, and conference centers, this amplifier provides exceptional audio quality, versatility, and energy efficiency. As part of Crown's DriveCore Install (DCi) DA Series, the 4|600DA amplifier is engineered to meet the needs of modern sound systems that rely on networked audio, offering the flexibility to drive low-impedance (2, 4, 8, 16 ohms) and high-impedance (70V, 100V) speaker systems.

At the heart of the DCi 4|600DA is Crown's exclusive DriveCore technology, a multi-patented innovation that integrates hundreds of discrete circuits into a single chip. This results in improved performance, higher reliability, and lower power consumption, making it one of the most energy-efficient amplifiers in its class. The amplifier's built-in DSP provides advanced digital signal processing capabilities, including input/output EQ, crossovers, delays, and LevelMAX limiters, enabling precise sound control and customization to fit the specific requirements of any installation.

The inclusion of Dante and AES67 support enables the DCi 4|600DA to seamlessly integrate into networked audio systems, allowing high-quality digital audio signals to be transmitted over a standard Ethernet network. This simplifies installation by reducing cabling requirements, making the amplifier an ideal choice for environments that rely on Dante for audio transport. With support for Dante Domain Manager, the amplifier offers enhanced security and management of Dante networks, making it a trusted option for larger, more complex audio installations.

System integrators will appreciate the advanced monitoring and control capabilities available through Harman's HiQnet Audio Architect software. This amplifier allows for real-time control, configuration, and monitoring over a TCP/IP network, ensuring that installers can easily manage multiple amplifiers from a central location. The DCi 4|600DA features continuous load monitoring, error reporting, and pilot tone monitoring to ensure system reliability and performance. Programmable General Purpose Input/Output (GPIO) ports provide additional integration and automation options, allowing the amplifier to be easily integrated into broader control systems.

The amplifier's universal power supply features Power Factor Correction (PFC), which guarantees maximum efficiency and reliable operation regardless of input voltage or location. With a wide voltage range of 100-240V at 50/60Hz, the DCi 4|600DA is capable of delivering consistent performance in various global installations. The advanced cooling system, with continuously variable speed forced air, directs airflow to critical components, ensuring the amplifier remains cool under heavy loads while minimizing noise, making it suitable for quiet environments.

In addition to its high-performance audio capabilities, the DCi 4|600DA includes advanced protection circuits to safeguard the amplifier and connected speaker systems. This includes protection against short circuits, DC faults, overheating, and mismatched loads. The amplifier's ability to drive 70V and 100V distributed speaker systems directly, without the need for step-up transformers, enhances audio quality while reducing the complexity of installation.

The DCi 4|600DA also supports power-saving features such as auto-standby mode, which automatically powers down the amplifier after 30 minutes of inactivity, reducing power consumption to less than 1W. Remote standby can be activated via the AUX port, further enhancing its energy efficiency. This amplifier is also compliant with Harman's GreenEdge initiative, incorporating environmentally friendly practices in its design, manufacturing, and packaging to minimize its environmental impact.

With its 2U rack-mountable design, the DCi 4|600DA is compact and easy to install in standard equipment racks. Weighing just 20.1 lbs, it provides robust power output across four channels while maintaining a lightweight and space-efficient form factor. This amplifier is perfect for installations that require both flexibility and high performance, ensuring that integrators can meet a wide range of audio needs with a single amplifier solution.

In summary, the Crown DCi 4|600DA is a powerful and flexible amplifier solution designed for networked audio environments. With 600W per channel, integrated Dante/AES67 support, advanced DSP features, and energy-efficient operation, it is an ideal choice for installations where high-quality, reliable audio and networked control are essential.
