Description
Crown Audio CDi 1000 Two Channel 500W Power Amplifier
The CDi 1000 is a rugged, lightweight professional power amplifier built for the demands of live sound and installed applications where versatility and reliability are non-negotiable. Its compact 2 RU rack footprint and switch-mode universal power supply make it equally suited to fixed installations or touring rigs, delivering consistent, transparent power across demanding load conditions night after night.
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. Play whatever load you're thrown on stage and trust the amp to perform.
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—your tone gets through clean and uncolored. 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, keeping your rig lean and your setup reliable.
