Crown DCi 4|300N - 300W 4-Channel at 4-Ohm 70V/100V Analog Power Amplifier with BLU Link

The Crown DCi 4|300N is a versatile and high-performance 4-channel amplifier that delivers 300W per channel at 4 ohms or 70V/100V, making it ideal for medium-scale installed sound applications such as conference rooms, retail spaces, and houses of worship. Part of Crown's renowned DriveCore Install (DCi) series, the DCi 4|300N utilizes Crown's proprietary DriveCore technology to ensure exceptional audio performance, efficiency, and reliability. This amplifier combines power and flexibility, with advanced network control, BLU Link audio transport, and high-quality DSP to meet the demands of modern audio installations.

The DCi 4|300N features BLU Link compatibility, enabling low-latency and fault-tolerant digital audio routing over standard Category 5e cabling. With the ability to route 256 channels across distances up to 100 meters, BLU Link provides an unprecedented level of flexibility in signal distribution for complex installations. This makes it ideal for distributed audio systems where networked audio transport is essential. The amplifier's integration with HiQnet Audio Architect ensures seamless control and monitoring over TCP/IP networks, allowing system integrators to configure, monitor, and adjust amplifier performance remotely with ease.

Equipped with advanced Digital Signal Processing (DSP), the DCi 4|300N provides a wide range of audio control options, including LevelMAX limiters for inputs and outputs, input compressors, and input/output EQs. These DSP features allow installers to fine-tune the audio system for optimal sound quality and speaker protection, ensuring clear, distortion-free sound in any environment. Additionally, the onboard signal generator and crossover functions make it easy to configure and test the system without the need for external processors, simplifying the setup process.

At the core of the DCi 4|300N is Crown's patented DriveCore technology, which integrates hundreds of discrete circuits into a single chip. This next-generation Class D amplifier topology allows for greater efficiency and reduced power consumption while maintaining high-fidelity audio performance. The amplifier is capable of directly driving both low-impedance (2/4/8/16 ohms) and high-impedance (70V/100V) speaker loads, eliminating the need for additional transformers and simplifying installation. This versatility makes the DCi 4|300N suitable for a wide range of applications, from distributed background music systems to more demanding commercial sound installations.

The amplifier's advanced protection circuitry ensures both the amplifier and connected speakers are safeguarded against potential damage from short circuits, DC faults, mismatched loads, overheating, and over/under-voltage conditions. Crown's TLC (Thermal Limiting Control) system intelligently reduces output levels to prevent overheating, ensuring the amplifier maintains reliable operation even under high-demand conditions. The DCi 4|300N also features Auto-Standby mode, which reduces power consumption to less than 1W when no input signal is detected for 30 minutes, making it energy-efficient and environmentally friendly.

The DCi 4|300N is equipped with a Power Factor Correction (PFC) universal power supply, which ensures stable operation across varying voltage conditions worldwide. This high-efficiency power supply reduces overall current draw and provides consistent power output, even in locations with unstable electrical grids. The amplifier's compact 2U rack-mountable design allows it to fit into standard audio racks, maximizing rack space efficiency while minimizing heat generation thanks to its revolutionary cooling system. The front-to-back forced air cooling system focuses airflow on critical components, ensuring optimal thermal management while keeping fan noise to a minimum, making it ideal for noise-sensitive environments.

The Crown DCi 4|300N also features comprehensive network monitoring and control capabilities, with real-time continuous load monitoring and error reporting, allowing integrators to monitor amplifier performance and detect issues before they impact audio quality. The inclusion of programmable General Purpose Input/Output (GPIO) ports adds further flexibility, enabling external devices to trigger functions such as preset recall, muting, or power on/off, making the amplifier suitable for installations requiring a high degree of customization.

With its combination of high power output, BLU Link compatibility, advanced DSP, and network control, the Crown DCi 4|300N is an ideal choice for professional installations that require reliability, flexibility, and high-quality audio performance. Its industry-leading features and cutting-edge technology ensure that it delivers exceptional sound quality and performance for a wide range of commercial audio applications.
