Crown Audio 2 – Channel Analog Power Amplifier

Crown DCi21250 DriveCore installation power amplifier

The Crown DCi21250 is part of the DriveCore Install (DCi) Series, a family of professional installation amplifiers designed for high-performance commercial audio applications. Built on Crown’s proprietary DriveCore technology, the amplifier combines advanced Class-D efficiency with robust output capability, offering reliable performance for complex distributed audio environments.

This model delivers 1250 watts of power per channel, providing strong and consistent output suitable for demanding installations. It supports both low-impedance (2–16 ohms) and high-impedance constant voltage systems (70V and 100V), making it highly adaptable for a wide range of speaker configurations. In bridge mono mode, the amplifier is capable of significantly higher output, enabling use in high-power applications such as subwoofers and large-scale sound reinforcement systems.

The DCi series is engineered for maximum installation flexibility. Channel-independent Hi-Z and Lo-Z selection allows each channel to operate independently, enabling mixed system designs within a single amplifier. Additionally, channel pairs can be bridged to increase power output, further extending system design options. This makes the amplifier suitable for everything from small distributed audio zones to high-demand performance environments.

Advanced power factor correction and a universal power supply ensure efficient energy usage across varying electrical conditions, while reducing heat dissipation. The integrated cooling system uses variable-speed fans to maintain optimal thermal performance with minimal noise impact. Designed for integration into professional control systems, the DCi21250 also supports remote on/off functionality for energy-efficient operation. With high rack density, flexible configuration options, and industry-leading efficiency, the Crown DCi21250 provides a powerful and scalable solution for modern installed sound systems.
