The DCI4300 DriveCore Install Series Analog Amplifier from Crown Audio is based on the Harman DriveCore technology, featuring PWM technology using Class D amplifier topologies.
The DCI4300 amplifier is designed, engineered, and manufactured to the industry’s high quality standards, and provides system integrators with great features and flexibility. The DCI4300 is versatile, compact, and energy-efficient.
True Rack Density
Power points of 600W in 2-channel configuration, in a 2RU form factor. More channels in one box allow smaller infrastructure rooms that can reduce operational costs while giving you installation flexibility.
Direct Drive Constant Voltage
Smaller gauge wiring drives the speakers using either 70Vrms or 100Vrms. With no need for a step-up transformer at the output, the DCI2600 efficiently produces high audio quality.
Channel Independent Hi-Z/Low-Z Selection
Drive either 1 or 2 speakers in Low-Z mode or literally hundreds of speakers in High-Z mode (70Vrms or100Vrms). This means better design flexibility since the DCI4300 powers all loads on a channel-by-channel basis.
Bridgeable Channel Pairs
The DCI4300 channels are bridgeable, even in 100Vrms mode, which means enhanced 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 advanced power supply in an installation amplifier delivers power more efficiently in almost any condition, resulting in less power dissipated and less heat in your racks.
70Vrms or 100Vrms Direct Drive Operation that is critical in running long speaker runs over a smaller wire
Bridgeable channel pairs even in 100Vrms operation
Next generation power factor correction universal power supply for maximum efficiency across a variety of voltages
Power saving features to minimize the end user's power consumption as much as possible
