Crown Audio DCI 4/300 DriveCore Install Analog Series 4-Channel Power Amplifier

Crown Audio DCI 4/300 DriveCore Install Analog Series  4-Channel Power Amplifier

The Crown DCI 4/300 is a high-performance 4-channel installation amplifier delivering 300 watts per channel into 2, 4, 8, or 16 ohms, as well as 70V and 100V constant-voltage systems. Its flexible design allows each channel to operate independently in Hi-Z or Low-Z mode via rear-panel DIP switches, and channels can be bridged for high-power applications such as driving subwoofers.

Each of the four channels includes an independent attenuator (0 to –80 dB), and the front panel provides clear status indicators for level/signal, ready, clip, thermal, and fault conditions—making system monitoring quick and intuitive. The 4/300 also integrates easily with control systems, offering remote power on/off and an energy-saving sleep mode when no audio is detected. It fits a standard 2U rack space and ships with wiring connectors and an IEC power cord.

Built on Crown’s proprietary DriveCore technology, the DCI series uses next-generation Class-D topologies and advanced PWM design to deliver clean, efficient, and reliable power. Its constant-voltage direct-drive capability eliminates the need for step-up transformers, ensuring higher audio fidelity. Crown’s “Minimum Guaranteed Power Ratings” ensure the amplifier consistently meets or exceeds its published specifications.
