Product description 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.
