About The Crown CDi 1000 DSP Power Amplifier
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, uncoloured 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.
Our Take
The Crown CDi 1000 is a versatile, powerful amplifier that can be used in just about any home, commercial or professional setting. It provides accurate, uncoloured sound with solid power to drive speakers well. The amplifier is rated for 2, 4 or 8 Ohm loads and 70V and 140V output, so you have plenty of configuration options. The CDi 1000 can drive speakers in a stereo arrangement, or provide bridged mono power as well.
The CDi 1000 gives you a wide range of DSP settings for shaping your sound from the rack. It's got six parametric filters per channel for the input EQ, plus high and low pass crossovers. Eight more parametric EQ filters per channel can be applied post-crossover, giving you the ability to carefully control just about any speaker setup. Adjustable time delay lets you dial in well-synced sound in distributed audio systems covering large spaces. And the CDi 1000's 19 user presets let you save all your DSP settings for quick and convenient recall.
