8Advanced Power Factor Correction (PFC) Universal Power Supply
The DCi 41250 Four-Channel Analog Power Amplifier from Crown Audio is a four-channel high-performance power amplifier from the DriveCore Install Analog Series which delivers 1250W of power at 4 ohms. It is recommended for installed sound, cinema, and recording broadcast.
True Rack Density
Four channels in one 2RU box allow smaller infrastructure rooms that can reduce operational costs while giving you installation flexibility.
Direct Drive Constant Voltage
The DCi 41250 helps economize by using smaller gauge wiring to drive the speakers using either 70 or 100 Vrms. DCi produces audio quality efficiently without a step-up transformer at the output.
Channel Independent Hi-Z/Low-Z Selection
Drive either one or two speakers in low-Z mode, or multiple speakers in high-Z mode (70 or 100 Vrms). DCi powers all loads on a channel-by-channel basis.
Bridgeable Channel Pairs
DCi Series' channels are bridgeable, even in 100Vrms mode, which allows 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 turn it on and off.
Efficient Cooling Design
Efficient internal cooling fans provide airflow to the 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 power supply is designed to keep down the amount of power being dissipated and the amount of heat building up in your racks.
