Crown Audio CDi 1000 Two Channel 500W Power Amplifier

The CDi 1000 is a rugged, lightweight professional power amplifier engineered for installed sound applications where versatility and reliability matter. Its compact 2 RU rack footprint and switch-mode universal power supply make it equally at home in fixed installations or mobile rigs, delivering consistent performance across demanding load conditions.

Power & Load Flexibility

This amplifier handles 2-, 4-, 8-ohm loads and 70V/140V distributed systems with authority. Output spans 275W per channel @ 8Ω, 500W per channel @ 4Ω, 700W per channel @ 2Ω, and up to 1,400W bridge-mono @ 4Ω, giving you the headroom needed for complex speaker configurations without requiring multiple units.

Audio Performance & DSP

A 100 dB signal-to-noise ratio, frequency response of +0/–1 dB from 20 Hz to 20 kHz, and damping factor better than 500 ensure transparent, controlled audio reproduction across the full spectrum. Onboard digital signal processing—including crossovers, EQ filters, delay, and output limiting—plus up to 20 user-defined presets give you deep configuration options without external processors.
