Description
Crown CDi4x300BL 4x300W Power Amplifier with BLU link
The Crown CDi4x300BL is a compact four-channel power amplifier built for live sound reinforcement, venue installations, and touring applications where reliability and control matter. Its lightweight DriveCore design delivers 300 watts per channel at 4 ohms with minimal footprint, making it practical for rigs where space is tight and dependability is non-negotiable. Network-controllable via BLU link digital audio bus, this amp integrates seamlessly into modern HARMAN ecosystems for remote monitoring and management during shows and events.
Power & Connectivity
Rated at 300 watts per channel across four channels, the CDi4x300BL handles both standard and high-impedance loads with 70V and 100V output capability, eliminating the need for external transformers in most live and installed setups. BLU link connectivity allows bidirectional digital audio transmission and network control, letting you monitor and adjust amplifier status and routing from your mixing console, a laptop, or any connected control device on the audio network—essential when you're running sound from a crowded stage or FOH position.
Onboard Processing & Integration
Built-in DSP provides parametric EQ, crossover, and limiting functions directly in the amplifier, reducing the number of external processors needed in your chain. Pre-loaded JBL speaker tunings allow instant optimization for compatible loudspeaker systems, while front-panel and network interfaces give you full control over channel routing, gain, and processing parameters on the fly—crucial for adapting to different venues without reprogramming.
