DCI4X300-U-NPFX

The Crown DriveCore™ Install (DCi) series amplifiers offer a complete line of high-performance installation amplifiers leveraging proprietary DriveCore technology. Designed and manufactured to the highest industry standards, DCi amplifiers provide system integrators with advanced features and flexibility for demanding 21st-century sound applications. Known for their versatility, compact size, and energy efficiency, DCi Series amplifiers continue Crown’s legacy of leadership in professional and commercial power amplifier technology.

**Performance Specifications:**
The DCi amplifiers are engineered to deliver exceptional audio performance. They have a frequency response of ±0.25dB (1W into 8Ω, 20Hz – 20kHz), ensuring precise sound reproduction across the entire audio spectrum. With a Signal to Noise Ratio (A-weighted) greater than 108dB, the amplifiers maintain a clean and noise-free output, crucial for high-quality sound systems. The Total Harmonic Distortion (THD) is kept below 0.35%, ensuring minimal signal distortion even at high output levels. The amplifiers can handle a maximum input level of +20dBu before compression and +26dBu before clipping, providing ample headroom for various audio signals. The voltage gain of 34dB ensures sufficient amplification for different input levels, making the DCi series suitable for a wide range of professional audio applications.

**Physical Specifications:**
DCi amplifiers are built with practical and robust physical features. They include balanced 3-pin block connectors for inputs, offering reliable and interference-free connections. The output connectors consist of a 2-pin terminal strip that accepts up to 10AWG terminal forks and bare wire, providing flexibility in installation. An AUX connector with a 3-pin block configuration is also included for additional connectivity options. The attenuation control is managed through a 21 detent potentiometer, allowing precise level adjustments from ∞ to 0dB. The amplifiers’ compact dimensions, 3.5” x 19” x 14.25” (8.75 cm x 47.5 cm x 35.63 cm) or 3.5” x 19” x 19” (8.9 cm x 48.3 cm x 48.3 cm), make them suitable for rack installations in tight spaces. They weigh between 18.8 lbs (8.53 kgs) and 30 lbs (13.6 kgs), depending on the model. The cooling system features a continuously variable speed fan with front-to-back airflow, ensuring efficient heat dissipation and quiet operation, which is essential in various professional settings.

**Network DCi Amplifiers:**
Network-enabled DCi amplifiers include additional features for enhanced control and integration. They come equipped with two RJ-45 connectors for BLU link input, allowing for easy network audio connections. For network monitoring and control, there is an additional RJ-45 connector, enabling remote management and system diagnostics. The amplifiers also feature an RJ-11 connector for General Purpose Input/Output (GPIO) control, offering two inputs and two outputs for versatile system integration and automation.

**Electrical Specifications:**
DCi amplifiers are designed with a universal power supply that accepts a wide range of AC mains voltages, from 100VAC to 240VAC at 50/60Hz (±10%), making them suitable for use in various global regions. The amplifiers are energy-efficient, drawing less than 1W of power in sleep mode, which is ideal for installations that prioritize energy savings. The power connector options include IEC 15A, 20A, and 30A, accommodating different power requirements and ensuring compatibility with various power distribution systems.

Overall, the Crown DriveCore™ Install series amplifiers are a top choice for professional audio installations, offering reliable performance, advanced features, and versatile connectivity options. Their design and engineering excellence make them suitable for a wide range of applications, from commercial installations to high-end professional sound systems.
