CROWN DCi 2|300 - Two-channel analog power amplifier, 300W @ 4Ω, 70V/100V

CROWN DCi 2|300 – Two-channel analog power amplifier, 300 W @ 4 Ω, 70 V/100 V

The CROWN DCi 2|300 is a high-efficiency, 2U rack-mount installation amplifier designed for commercial and corporate environments requiring low-impedance , constant-voltage (70V/100V) power supplies without external transformers. Featuring DriveCore technology, it delivers 300W continuous per channel into 4Ω and maintains linear response from 20Hz to 20kHz with less than 0.35% harmonic distortion. Its compact design and active PFC -corrected power minimize consumption and heat generation, while front-to-back fan cooling ensures quiet, reliable operation.

Main features

• True rack density: 300W or 600W in 2/4/8-channel configurations in just 2U, optimizing space and infrastructure.
• Constant Direct Drive: 70V and 100V outputs without the need for a transformer, with smaller gauge wiring and higher audio quality.
• Independent Hi-Z/Low-Z selection: Each channel can drive 2–16 Ω loads or constant voltage systems, adapting to the installation design.
• Bridgeable Channels: Mono bridging possible, even in 100V mode, for subwoofer or higher power applications.
• Efficient cooling: Variable speed internal fans maximize heat extraction and minimize noise (≤ 45 dBA @ 1 m).
• Advanced PFC: Universal power supply with power factor correction for lower consumption and heat dissipation.

Product benefits

• Versatile installation: supports both low-impedance speakers and 70V/100V lines without additional equipment.
• Energy savings: DriveCore and PFC efficiency reduce operating costs and thermal stress on racks.
• Continuous reliability: protection circuits against short circuits, no-load and on/off spikes.
• Quiet operation: proportional ventilation and compact design for demanding environments.
• Professional Design: OEM cover with durable metal finish and 15A IEC connector.

Use cases

• Public address and voice evacuation systems in hotels, hospitals, and corporate buildings.
• Background audio and reinforcement in restaurants, stores, auditoriums, and convention centers.
• AV installations in museums, multipurpose spaces, and conference rooms that require cabling flexibility.

Frequently Asked Questions

• How do I activate bridge mode? On the rear panel, select “Bridge” to combine both channels into mono.
• Do I need a transformer for 70V/100V? No; the amplifier delivers constant voltage directly without any intermediate steps.
• What keeps distortion so low? DriveCore technology and an active PFC reduce leakage current and correct harmonic peaks.
