CROWN DCi 8|300 - Eight-channel analog power amplifier, 300W @ 4Ω, 70V/100V

CROWN DCi 8|300 – Eight-channel analog power amplifier, 300 W @ 4 Ω, 70 V/100 V

The CROWN DCi 8|300 is part of Crown’s DriveCore™ Install Series, offering eight independent 300W per channel into 4Ω with 300W direct output at 70V and 100V without external transformers. Its 2U rack form factor maximizes installation density ( True Rack Density ), allowing more channels in less space and reducing infrastructure costs. With universal power supply and active power factor correction (PFC), and variable speed forced cooling, it ensures maximum efficiency and reliability in commercial and professional environments.

Main features

• True Rack Density: eight 300W channels in just 2U height.
• Direct constant voltage: 300W at 70V/100V without the need for a step-up transformer.
• Independent Hi-Z/Lo-Z selection: channel by channel, 2 Ω–16 Ω or 70 V/100 V.
• Bridgeable Channels: Configurable channel pairs even in 100V mode for subwoofers.
• Balanced analog inputs: automatic priority switching between two sources.
• Remote On/Off Interface: for integration into external control systems.
• Efficient cooling: front-to-back fans in the amplifier block are quiet and energy-efficient.
• Universal power supply with advanced PFC: 100–240 VAC, 50/60 Hz, reduces thermal dissipation.

Product benefits

• Installation flexibility: high channel count in a compact rack, ideal for control rooms and small AV cabinets.
• Savings on wiring: direct constant voltage allows the use of smaller section cables over long distances.
• High reliability: Passive signal design and active PFC minimize failures and overheating.
• Sound adaptability: bridgeable outputs and impedance selection for various speaker configurations.
• Comprehensive management: input priority and remote control facilitate automation and monitoring.

Use cases

• Zone-based sound reinforcement in hotels, shopping centers, and airports.
• Corporate AV installations and auditoriums with multiple audio sources.
• Public address and background music systems in theaters, conference rooms, and educational centers.

Frequently Asked Questions

• How do you select Hi-Z or Lo-Z? Via rear DIP switches, channel by channel.
• Do you need transformers for 70V/100V? No; the constant voltage output is direct.
• Can channels be bridged? Yes; channel pairs can even be bridged in 100 V mode for higher power.
• Does it require DSP configuration? It doesn't include integrated DSP; it's a simplified analog version.
