The CDi Series of Crown amplifiers are professional tools designed and built for
installed sound applications. CDi stands for Contractor Digital Intelligence. The series includes two models which are identical except for output power: CDi 1000 and
CDi 2000. Both are rugged and lightweight, and offer unmatched value in their class.

CDi Series amplifiers feature an LCD screen with DSP speaker presets for crossover frequencies, EQ, limiting, compression, delay, and a subharmonic synthesizer. Other features include a switch-mode universal power supply, useful function indicators, proportional-speed fan-assisted cooling, removable Phoenix-style inputs, barrier strip outputs for low-Z or 70V/140V loads, short-circuit protection and more.

Features
Accurate, uncolored sound with very low distortion for the best in music and voice reproduction
Advanced protection circuitry guards against: shorted outputs, open circuits, DC, mismatched loads, general overheating, high-frequency overloads and internal faults
Extremely versatile, handling a wide range of speaker impedances and outputs
Switch-mode universal power supply
Integrated DSP with LCD front panel display
Speaker presets for crossover frequencies, EQ, limiting, compression, delay, and subharmonic synthesis
All products fill 2U rack spaces and weigh under 19 pounds
Barrier strip outputs for low-Z or 70V/140V loads, removable Phoenix-style inputs
Three-Year, No-Fault, Fully Transferable Warranty completely protects your investment and guarantees its specifications.
