Crown Audio CDi 1000 2-Channel 500W Commercial Amplifier

The Crown Audio CDI1000 is a power amplifier built for permanent installations that demand dependable output and clear reproduction. Each of its two channels delivers up to 500 watts into a 4-ohm load, providing the headroom needed for music playback, paging, and announcements in restaurants, retail spaces, offices, and similar venues.

For distributed audio, the amplifier offers 70-volt and 140-volt constant voltage options, allowing long speaker runs without additional transformers. If a single zone requires higher output, you can switch the unit into bridge-mono mode and combine both channels into one powerful feed.

A steel chassis that is both rugged and lightweight slides neatly into a standard two-rack-unit space, so it integrates cleanly with mixers, processors, and source equipment. Inside, a switch-mode universal power supply accepts global AC voltages and maintains stable performance even when mains power fluctuates.

System tuning happens right at the amplifier. An integrated DSP provides adjustable crossovers, parametric EQ, output limiting, and other essentials. A backlit LCD on the front panel gives direct access to presets and settings, streamlining on-site adjustments without extra hardware.

Protection circuitry monitors temperature, short circuits, and overload conditions, shutting down only the affected channel if a fault occurs. This approach helps keep the rest of the system running while preventing damage, making the CDI1000 a reliable choice for demanding commercial environments.
