Crown DCi 4|300 4-Channel 300W At 4ohms, 70V Amplifier

The DCI 4/300 DriveCore Install Analog Series from Crown Audio is a 4-channel amplifier capable of producing 300 watts of output per channel and works with 2, 4, 8, and 16 Ohms or 70 or 100 Vrms. Channels can be bridged for powering higher power applications such as a subwoofer. The 4/300 also has channel-independent high- or low-impedance output that is selectable from the rear-panel DIP switches. This allows you to integrate the amplifier into a variety of different setups. Each of its 4 channels additionally features independent attenuators with an attenuation range from 0 to -80 dB.

The Crown Audio DCI 4/300 DriveCore Install Analog Series amplifier sets a new standard in professional installed sound systems. Featuring four channels of 300W output each, this versatile Class-D amplifier supports 2, 4, 8, 16 Ohm loads and 70V/100V constant voltage outputs, making it ideal for commercial audio, performance venues, houses of worship, and educational facilities.

Thanks to Crown’s patented DriveCore technology, the DCI 4/300 delivers consistent, high-fidelity audio with minimal distortion and superior energy efficiency. Each channel includes independent level controls and selectable high- or low-impedance modes for maximum installation flexibility. The unit’s advanced PFC universal power supply ensures optimal performance across 100–240 VAC, while its efficient cooling system minimizes noise and heat.

The amplifier’s auto-standby PowerSave mode, bridgeable channels, and remote on/off interface provide smart control options that reduce operational costs and simplify integration into automation systems.

Whether you’re powering distributed speakers or high-demand subwoofers, the Crown DCI 4/300 delivers superior performance, flexibility, and reliability in a compact 2U rackmount design.y

Crown DCi 4|300 Features

• TRUE RACK DENSITY – Power points of 300W or 600W in 2-/4-/8-channel configurations – all in a 2 Rack Unit form factor. More channels in one box allow smaller infrastructure rooms that can reduce operational costs while giving you the utmost in installation flexibility.
• DIRECT DRIVE CONSTANT VOLTAGE – Save money by using smaller gauge wiring to drive the speakers using either 70V rms or 100Vrms. With no need for a step-up transformer at the output, the DCi produces higher audio quality much more efficiently.
• CHANNEL INDEPENDENT HI-Z/LOW-Z SELECTION – Drive either one or two speakers in low-Z mode, or literally hundreds of speakers in high-Z mode (70Vrms or 100Vrms). This means better design flexibility since DCi powers all loads on a channel-by-channel basis.
• BRIDGEABLE CHANNEL PAIRS – Unlike amps from other manufacturers, the DCi Series channels are bridgeable – even in 100Vrms mode – which means even more adaptability for higher power applications such as subwoofers.
• REMOTE ON/OFF INTERFACE – Save power by integrating the amplifier into a control system so you can easily turn it on and off.
• EFFICIENT COOLING DESIGN – Highly efficient internal cooling fans provide airflow to the most heat-generating parts. Incorporating the fans into the amplifier brick design maximizes cooling while minimizing wasted energy and noise.
• ADVANCED POWER FACTOR CORRECTION (PFC) UNIVERSAL POWER SUPPLY – The most advanced power supply in an installation amplifier delivers power more efficiently in almost any condition than anyone else, resulting in less power dissipated and less heat in your racks.
