Crown CDi1000 2-Channel Amplifier for Installed Sound Applications 70V / 140V

Description

Crown CDi 1000 Two-Channel Commercial Amplifier 500W/Channel at 4 Ohms CDi1000
The 2 RU rack-mountable Crown Audio CDi 1000 is a rugged, lightweight commercial power amplifier designed for dual-channel or bridge-mono operation in installed audio applications such as restaurants, retail stores, warehouses, offices, and more. The CDi 1000 provides accurate, uncolored sound with low distortion for excellent music and vocal reproduction. It delivers 500W per channel at 4 Ohms, and supports multiple low-impedance configurations, as well as 70V and 140V constant-voltage systems. The switch-mode universal power supply enables safe operation across the globe.
Advanced protection circuitry guards against shorted outputs, open circuits, DC, mismatched loads, general overheating, high-frequency overloads and internal faults. The CDi 1000 also has integrated DSP presets for adjustable crossover frequencies, EQ, limiting, compression, delay, and a subharmonic synthesizer. A backlit LCD displays relevant information. The removable Euroblock inputs and barrier strip outputs accommodate a variety of system setups.
