CROWN CDi 2000 - Two-channel power amplifier, 800W @ 4Ω, 70V/140V

CROWN CDi 2000 – Two-channel power amplifier, 800 W @ 4 Ω, 70 V/140 V

The CROWN CDi 2000 is a professional 2U rackmount amplifier delivering 800W per channel into 4Ω and supporting both 70V and 140V constant voltage systems without the need for external transformers. Based on the robust CDi Series, it features a universal switching power supply with active PFC for maximum energy efficiency and an integrated DSP with LevelMAX™ crossovers, EQs, delays, and limiters configurable from its intuitive front-facing LCD display or via HiQnet™ over TCP/IP for remote monitoring and control. Lightweight, reliable, and sounding faithful, the CDi 2000 is ideal for commercial, corporate, and hospitality environments where performance and ease of setup are required.

Main features

• Output power: 800 W @ 4 Ω; 475W @ 8Ω; 1000W bridged @ 4Ω; 800W@70V; 800W @ 140V
• Integrated DSP: crossovers, parametric EQ, delays (input 0–1000 ms, output 0–100 ms) and LevelMAX™ limiters
• Front display: Backlit LCD with push-button navigation for quick adjustment
• Inputs/Outputs: Balanced Phoenix input; 2–8 Ω and 70/140 V barrier output
• Advanced protections: against short circuits, overload, DC, overheating and internal failures
• Network control: HiQnet™ Audio Architect for monitoring, control and preset backup
• Lightweight chassis: 2U rack space, robust construction and reduced weight for versatile installations

Product benefits

• Precise sound: low noise and distortion for clear music and vocal reproduction
• Quick installation: DSP presets and LCD display simplify commissioning
• Total flexibility: dual and bridged modes, 2–16 Ω loads, and transformerless constant voltage
• Energy efficiency: switching power supply with active PFC reduces consumption and dissipated heat
• Remote control: adjust all parameters via HiQnet™ on a TCP/IP network

Use cases

• Ambient sound and paging systems in restaurants, shops, and offices
• Sound reinforcement in auditoriums, conference rooms and convention centers
• Public address and voice evacuation systems in hotels and hospitals

Frequently Asked Questions

• How do I configure it in bridge mode? Select “Bridge” from the DSP menu or via HiQnet™ to achieve up to 1000 W at 4 Ω.
• Do you need a transformer for 70V/140V? No; it operates at native constant voltage without additional hardware.
• Can user memory be stored? Yes; up to 20 user-defined presets can be stored in the DSP.
