Description
Crown Audio CDi 1000 Two Channel 500W Power Amplifier
The CDi 1000 is a compact, efficient professional power amplifier built for studio and mobile recording setups where versatile load handling and rock-solid reliability are essential. Its 2 RU rack footprint and switch-mode universal power supply adapt seamlessly to any studio configuration—from permanent installations to portable session rigs—delivering consistent, transparent amplification across demanding monitoring and playback scenarios.
Power & Load Flexibility
This amplifier handles 2-, 4-, 8-ohm loads and 70V/140V distributed systems, giving studio engineers the flexibility to work with any monitor or speaker topology. Output spans 275W per channel @ 8Ω, 500W per channel @ 4Ω, 700W per channel @ 2Ω, and up to 1,400W bridge-mono @ 4Ω, providing sufficient headroom for complex studio speaker arrays and live monitoring chains without requiring external amplification.
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 reproduction that preserves mix details across the full spectrum. Onboard digital signal processing—including crossovers, EQ filters, delay, and output limiting—plus up to 20 user-defined presets enable precise shaping of your monitoring and playback chain without external processors, streamlining session workflow.
