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

The Crown DCi 4|600 is a versatile and highly efficient 4-channel analog power amplifier that delivers 600W per channel at 4 ohms, making it an excellent choice for a variety of medium to large-sized installation applications such as cinemas, houses of worship, bars, lounges, and more. Based on Crown's proprietary DriveCore technology, this amplifier integrates cutting-edge Class D amplifier topologies, offering superior audio performance, reliability, and energy efficiency in a compact 2U rackmount form factor. The DCi 4|600 is designed to meet the rigorous demands of professional sound installations while offering significant flexibility and ease of use.

One of the standout features of the DCi 4|600 is its Direct Drive capability, which allows each channel to be individually selectable for low-Z or high-Z operation, eliminating the need for transformers. This enables the amplifier to provide constant voltage at 70V or 100V, making it an ideal solution for distributed audio systems. The higher voltage output allows for more speakers per output, reducing wiring costs and simplifying installation while maintaining high-quality audio performance. This makes the DCi 4|600 a highly flexible amplifier for both low-impedance and constant-voltage speaker systems.

Crown's exclusive DriveCore technology is at the heart of the DCi 4|600, combining hundreds of discrete circuits into a single chip. This innovation results in better performance, lower power consumption, and improved reliability. DriveCore technology also allows for superior audio fidelity by minimizing distortion and maintaining high signal clarity across all channels. With a signal-to-noise ratio greater than 108dB, the DCi 4|600 ensures crystal-clear audio reproduction, making it ideal for both music and voice applications.

The amplifier features advanced protection circuits that safeguard both the unit and connected speakers from potential damage. These circuits protect against shorted outputs, DC offset, mismatched loads, overheating, over- or under-voltage, and high-frequency overload. Additionally, Crown's TLC (Total Linear Control) protection helps prevent overheating by intelligently reducing gain when necessary, ensuring the amplifier continues to operate safely even under extreme conditions. This level of protection makes the DCi 4|600 a reliable choice for installations that require continuous, uninterrupted performance.

Energy efficiency is a key focus of the DCi 4|600, with several built-in power-saving features. The amplifier consumes less than 1W of power in sleep mode, and the auto-standby feature automatically puts the unit into sleep mode after 30 minutes of no input signal, reducing energy consumption in long-term installations. The amplifier can also be remotely powered on or off through the AUX port, allowing for easy integration into automated control systems. This makes the DCi 4|600 an environmentally friendly and cost-effective solution for professional installations.

The amplifier is equipped with a sophisticated cooling system that uses continuously variable-speed forced air to direct airflow from front to back. This cooling system focuses airflow on the areas that need it most, maximizing cooling efficiency while minimizing noise. With a maximum fan noise level of 45dB, the DCi 4|600 is suitable for environments where low noise is essential, such as conference rooms, theaters, and houses of worship.

In terms of connectivity, the DCi 4|600 offers barrier strip outputs for both low-Z and high-Z speaker systems, as well as removable Phnix-style inputs for easy installation. The amplifier also features an AUX port, providing additional flexibility for system integrators by allowing remote on/off control and amplifier fault monitoring. This level of integration makes the DCi 4|600 a versatile choice for professional audio installers who require a flexible, high-performance solution.

Housed in a compact 2U rackmount chassis, the DCi 4|600 measures 19 x 14.24 x 3.5 inches and weighs 20.1 lbs, making it easy to install in standard racks. Despite its compact size, the amplifier delivers exceptional power and performance, with output power ratings of 600W at 4 ohms and 70V/100V, making it capable of driving demanding audio systems in various environments.

With its powerful performance, energy efficiency, and advanced features, the Crown DCi 4|600 is an ideal solution for professional sound installations that require a reliable, high-quality amplifier with flexible configuration options. Whether used in distributed audio systems or low-impedance speaker setups, the DCi 4|600 provides the flexibility and performance that professional integrators need.
