Crown CDI-4000
Product Description
Crown CDi Series amplifiers are professional tools designed and built for installed sound applications. The series includes three models which are identical except for output power: CDi 1000, CDi 2000, and CDi 4000. All are rugged and lightweight, and offer unmatched value in their class.
* Extremely versatile; rated for 2-, 4-, 8-ohm loads and 70V and 140V outputs. * Switch-mode universal power supply. * Intuitive front-panel LCD screen for quick, easy configuration. * Onboard digital signal processing includes crossovers, EQ filters, delay, and output limiting. * Up to 20 user defined DSP presets are available. Specifications Frequency Response (at 1 watt into 4 ohms, 20Hz - 20 kHz) +0/–1 dB Signal to Noise Ratio (below rated 8-ohm power at 1 kHz, A-weighted) 100 dB Damping Factor (8 ohm): 20 Hz to 400 Hz > 500 Input Stage Input is electronically balanced and employs precision 1% resistors AC Line Current CDi 1000: 11.50A, CDi 2000: 11.93A, CDi 4000: 11.75A At idle: Draws no more than 45 watts.
