Crown Audio CDI1000

Overview

The Crown Audio CDI1000 is a 2-channel commercial power amplifier designed for permanent installations that require reliable and clear audio output. Each channel delivers up to 500 watts into a 4-ohm load, making it suitable for music playback, paging, and announcements in environments such as restaurants, retail spaces, and offices. Its flexible voltage options and robust build ensure consistent performance in demanding commercial settings.

Key features

• Provides 500 watts per channel at 4 ohms, offering ample headroom for clear and powerful sound.
• Selectable 70-volt and 140-volt constant voltage outputs support long speaker runs without the need for additional transformers.
• Bridge-mono mode combines both channels into a single, higher-output feed for zones requiring more power.
• Integrated digital signal processing (DSP) includes adjustable crossovers, parametric equalization, and output limiting for precise system tuning.
• Backlit LCD on the front panel allows quick access to presets and settings, simplifying on-site adjustments without extra equipment.
• Rugged yet lightweight steel chassis fits neatly into a standard two-rack-unit space, facilitating clean integration with other audio gear.
• Switch-mode universal power supply accepts global AC voltages and maintains stable operation even with fluctuating mains power.
• Advanced protection circuitry monitors temperature, short circuits, and overloads, shutting down only the affected channel to keep the rest of the system running safely.

Key specs

• Power output: 500 W per channel at 4 ohms
• Channels: 2 (stereo) with bridge-mono capability
• Voltage options: 70 V and 140 V constant voltage outputs
• Chassis size: 2 rack units
• Power supply: Switch-mode universal, compatible with global AC voltages

Connectivity and compatibility

The amplifier is designed to integrate seamlessly into commercial audio systems, supporting both low-impedance and constant voltage speaker configurations. Its flexible output options make it compatible with a wide range of distributed audio setups, allowing installers to tailor the system to the venue’s specific needs. The bridge-mono mode further extends its versatility by providing a higher power output option for single-zone applications.

Performance and reliability

Built to withstand the rigors of commercial use, the CDI1000 features a steel chassis that balances durability with manageable weight. The universal power supply ensures consistent performance worldwide, while the integrated DSP allows fine-tuning of audio parameters directly at the amplifier. Protection features minimize downtime by isolating faults to individual channels, helping maintain system operation during unexpected conditions.

Ideal uses and environments

This amplifier is well suited to venues that require dependable, high-quality audio distribution such as restaurants, retail stores, offices, and other commercial spaces. Its ability to handle both music and paging makes it a versatile choice for environments where clear announcements and background music are essential. The compact rack size and straightforward controls also make it a practical option for professional installers and system integrators.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
