Crown CDI4X300BL – 4-Channel 300W DriveCore Amplifier with BLU link
Product Overview
The Crown CDI4X300BL is a four-channel, 300-watt-per-channel CDi DriveCore Series amplifier with integrated BLU link digital audio networking, designed for commercial AV installations using Harman's BLU link audio-over-Cat infrastructure. The BLU link interface enables lossless digital audio transport between the CDI4X300BL and compatible BSS Audio signal processors over standard Cat cable, making it a natural specification for AV integrators deploying Harman BSS-based processing with Crown amplification in conference centers, houses of worship, and commercial facilities.
Product Description
The CDI4X300BL delivers 300 watts per channel into 4 ohms across all four channels with 70V and 100V constant-voltage output support. The integrated BLU link interface provides 256-channel digital audio transport at up to 96kHz/24-bit resolution over a single shielded Cat cable, eliminating multi-core analog runs between the BSS processor and the amplifier. Crown's proprietary DriveCore IC integrates driver and output stages for thermal efficiency in permanent rack installations. The amplifier includes comprehensive DC, thermal, and short-circuit protection on all four channels.

Frequently Asked Questions
- What BSS Audio processors are compatible with BLU link?
- BLU link is compatible with BSS Audio Soundweb London processors including the BLU-800, BLU-806, BLU-DAN, and other BLU link-enabled BSS devices. Consult the Harman BSS Audio compatibility list for current supported models.
- Does BLU link require special cabling?
- BLU link uses shielded Cat5e or Cat6 cable. Standard unshielded Cat cable is not recommended for BLU link connections in commercial installations.
- Can the CDI4X300BL be used without BLU link?
- The CDI4X300BL includes analog XLR inputs that can be used when BLU link is not required, though the amplifier is primarily specified for BSS BLU link-enabled system architectures.
