Crown CDi 1000 Two-Channel Power Amplifier

The Crown CDi 1000 is a two-channel power amplifier built for the demands of installed sound, where reliability and set-it-and-forget-it operation are paramount. Delivering 500 watts per channel into 4-ohm loads, it handles everything from background music systems to moderate-volume speech reinforcement with ease. Its support for 2-ohm, 4-ohm, 8-ohm, 70V, and 140V outputs means a single amplifier model can serve low-impedance direct-connected speakers or distributed ceiling speaker systems, simplifying inventory and system design for integrators.

What sets the CDi 1000 apart from basic power amplifiers is its integrated digital signal processing. The onboard DSP includes crossover filters, parametric EQ, signal delay, and output limiting — tools that would otherwise require separate outboard gear. Up to 20 user presets can be stored and recalled from the front-panel LCD, making it straightforward to switch configurations for different events or zones. The switch-mode universal power supply keeps the unit at a manageable 22 pounds while delivering consistent performance, and the steel-and-aluminum construction ensures long-term durability in rack-mounted installations.
