CROWN CDi 4|1200BL - Analog input amplifier + Blu Link, 4 channels, 1200W per output channel

CROWN CDi 4|1200BL – Analog input amplifier + BLU Link™, 4 channels, 1,200 W per channel

The CROWN CDi 4|1200BL is a high-power installation amplifier designed for large-scale environments (cinemas, houses of worship, hotels, cruise ships, auditoriums). It delivers 1,200 W continuous per channel into 4 Ω and can drive loads up to 100 Vrms without an external transformer. It features exclusive DriveCore™ technology for over 90% efficiency, a powerful DSP with pre-configured JBL presets, and HARMAN's BLU Link™ digital bus, which allows up to 256 channels of audio to be sent and received at low latency over Cat5e cable. A front-facing interface with LCD display and dedicated buttons, along with HiQnet™ TCP/IP remote monitoring and control, make setup and parameter adjustment (input router, delays, parametric EQs, crossover, LevelMAX™ limiters) quick and easy. The universal power supply with active PFC and variable speed forced cooling ensures reliable and quiet operation in critical applications.

Product benefits

• Power and density: 4 channels of 1,200 W in just 2 U of rack space free up space for more equipment.
• Quick setup: JBL presets and BLU Link™ make setup quick without any transformers.
• Centralized control: remote monitoring and adjustment from HiQnet™ and Audio Architect.
• Custom tuning: Full DSP to optimize response and dynamics in each room.
• Efficiency and reliability: DriveCore™ and active PFC minimize consumption and heat, and variable cooling reduces noise.

Use cases

• Sound reinforcement for large cinemas and auditoriums with multiple zones and limited racks.
• Public address and voice evacuation systems in hotels, airports, and leisure venues.
• AV installations in temples, convention centers and cruise ships with network control.

Frequently Asked Questions

• Do you need transformers for 100 V? No; it delivers high native voltage without external transformers.
• How do I adjust the DSP presets? From the front display or via HiQnet™ Audio Architect.
• What is the latency of BLU Link™? Less than 1 ms, ideal for precise synchronization on long runs.
