Crown DCi 4|300DA - 300W 4-Channel at 4-Ohm 70V/100V Analog Power Amplifier with Dante

The Crown DCi 4|300DA is a 4-channel, 300W per channel analog power amplifier with integrated Dante and AES67 networked audio capabilities, designed to deliver high-performance sound in professional installed sound applications. As part of Crown's DriveCore Install (DCi) series, the 4|300DA offers a flexible and energy-efficient solution for small to medium-sized installations such as houses of worship, corporate buildings, theaters, and educational facilities. With the ability to drive low-Z (2, 4, 8, 16 ohms) and high-Z (70V, 100V) speaker systems, this amplifier ensures versatility and scalability for a wide range of sound systems.

At the core of the DCi 4|300DA is Crown's patented DriveCore technology, a multi-patented circuit design that integrates hundreds of discrete circuits into a single chip. This not only increases performance and reliability but also reduces power consumption, resulting in superior energy efficiency. The amplifier is equipped with advanced digital signal processing (DSP) for comprehensive control over the sound output. Features such as input/output EQ, crossover, input/output delay, and LevelMAX limiters ensure precise audio customization to suit the needs of any installation.

With Dante and AES67 compatibility, the DCi 4|300DA simplifies audio distribution by allowing high-quality digital audio signals to be transmitted over a standard Ethernet network. This greatly reduces cabling requirements and makes the amplifier an ideal choice for modern audio-over-IP environments. The amplifier also supports Dante Domain Manager, ensuring secure and flexible networked audio management in larger installations. Its compliance with EN 54-16 means it is suitable for life safety applications, further broadening its use in critical environments.

For system integrators, the DCi 4|300DA offers extensive control and monitoring capabilities via Harman's HiQnet Audio Architect software. This software allows real-time control and configuration of the amplifier over a TCP/IP network. The amplifier features advanced load monitoring, comprehensive error reporting, and programmable General Purpose Input/Output (GPIO) ports for enhanced system integration. It also includes an adjustable auto-standby mode and a remote standby function, activated via the AUX port, to save power when the amplifier is not in use, further contributing to energy efficiency.

The amplifier's power supply is designed for universal use, supporting a wide input voltage range of 100-240V, 50/60Hz. The advanced Power Factor Correction (PFC) power supply guarantees maximum efficiency and consistent performance even under demanding electrical conditions. The cooling system uses continuously variable speed forced-air fans, focusing airflow to the critical components of the amplifier. This design ensures the amplifier remains cool and efficient while keeping fan noise to a minimum, making it ideal for quiet environments.

Built for reliability and durability, the DCi 4|300DA is equipped with Crown's advanced protection circuitry to safeguard both the amplifier and connected speakers. This includes protection against short circuits, DC faults, overheating, and mismatched loads. Additionally, the amplifier supports direct drive for 70V and 100V systems on a per-channel basis, eliminating the need for step-up transformers and enhancing audio quality in distributed speaker systems.

The DCi 4|300DA's compact 2U rack-mountable design offers true rack density, packing 300W of power across four channels in a single chassis. Its lightweight construction at 20.1 lbs makes it easy to install in any standard equipment rack, while maintaining the power and versatility needed for high-performance audio systems. In keeping with Harman's GreenEdge initiative, the amplifier is designed with environmentally friendly practices in mind, including low power consumption in standby mode and energy-efficient operation, making it a responsible choice for integrators focused on sustainability.

In conclusion, the Crown DCi 4|300DA is a versatile, high-performance power amplifier that delivers 300W per channel, supports Dante and AES67 networked audio, and is designed to drive both low- and high-impedance speaker systems. With its advanced DSP features, network control, and energy-efficient design, this amplifier is the perfect solution for modern installations that require powerful, flexible, and reliable sound distribution.
