Description
The Crown DCi 4|1250 is a high-power four-channel installation amplifier designed for demanding commercial and professional audio applications. Delivering 1250 watts per channel at 4Ω, the amplifier combines exceptional power density, installation flexibility, and energy efficiency in a compact 2RU rackmount chassis. Supporting both low-impedance and 70V/100V distributed audio systems, the DCi 4|1250 features Direct Drive Constant Voltage technology, channel-independent Hi-Z/Low-Z operation, bridgeable outputs, and an advanced Power Factor Correction (PFC) universal power supply. It is an ideal solution for large-scale sound reinforcement, distributed audio systems, and high-power loudspeaker installations.
