DCi 4|300 Four-channel, 300W @ 4Ω Analog Power Amplifier, 70V/100V

DriveCore™ Install (DCi) Series Amplifiers

The DriveCore™ Install (DCi) Series is a full line of high-performance installation amplifiers built on Crown’s proprietary DriveCore technology. Designed, engineered, and manufactured to the highest industry standards, DCi amplifiers give system integrators the advanced features, flexibility, and reliability needed for demanding 21st-century installed sound applications. Compact, versatile, and highly energy-efficient, the DCi Series continues Crown’s long-standing tradition of leadership in professional and commercial amplification.

Features

• True Rack Density – Offers 300W or 600W per channel in 2-, 4-, or 8-channel configurations within a 2RU form factor. More channels in one unit reduce infrastructure requirements, lower operational costs, and provide maximum installation flexibility.

• Direct Drive Constant Voltage – Drives speakers at 70V RMS or 100V RMS without step-up transformers, improving audio quality and efficiency while allowing the use of smaller-gauge wiring.

• Channel-Independent Hi-Z/Low-Z Selection – Each channel can power one or two speakers in low-Z mode, or hundreds of speakers in high-Z mode, providing design flexibility on a per-channel basis.

• Bridgeable Channel Pairs – Channels can be bridged, even in 100V RMS mode, enabling higher-power applications such as subwoofers.

• Remote On/Off Interface – Integrates with control systems for easy power management and energy savings.

• Efficient Cooling Design – Internal fans direct airflow to heat-generating components, maximizing cooling while minimizing noise and wasted energy.

• Advanced Power Factor Correction (PFC) Universal Power Supply – Delivers highly efficient power in nearly any condition, reducing heat and energy dissipation in racks.

The DCi Series amplifiers provide reliable, flexible, and professional-grade performance, making them ideal for modern installed audio systems.
