About Crown Audio CDI 4X300

A pinnacle of audio amplification, the CDi 4X300BL DriveCore Series 4-Channel Power Amplifier embodies a powerful fusion of high-quality performance, advanced features, and cost-effectiveness. Drawing on the elite technology of Crown Audio's flagship DriveCore Install series, this robust amplifier is engineered to excel in a myriad of environments, from the intimate acoustics of restaurants to the dynamic demands of retail spaces.

The CDi 4X300BL is not just an amplifier; it's a comprehensive audio solution offering four channels, each delivering a potent 300 watts into 8 ohms. Its built-in digital signal processor (DSP) provides granular audio control, enabling precise equalization, compression, and delay adjustments to fine-tune the listening experience. The inclusion of Class 2 wiring facilitates extended cable runs, enhancing installation flexibility and making it ideal for both 70V and 100V applications.

Network control and monitoring are seamless through HARMAN's HiQnet Audio Architect software, allowing for sophisticated configuration and real-time oversight via a standard TCP/IQ network. The BLU link feature, exclusive to BL models, ensures robust, fault-tolerant audio BUS communication across 256 channels, streamlining the integration of multiple audio sources and outputs.

The DriveCore Technology at the heart of the CDi 4X300BL is Crown's proprietary innovation, significantly reducing the internal component count, which in turn minimizes variability and boosts reliability. This leads to unparalleled audio fidelity from an impressively efficient design.

Each channel of the CDi 4X300BL is capable of direct drive to 70V or 100V outputs, catering to high impedance applications without the need for transformers. The front-panel interface offers intuitive configuration, while the combined GPIO/AUX Port allows for preset recall, channel muting, fault monitoring, and amplifier power control.

To expedite installation and ensure optimal performance, the CDi DriveCore series comes pre-loaded with JBL speaker tunings, compatible with a wide range of speaker configurations. This amplifier is a testament to Crown Audio's commitment to producing durable, efficient, and high-performing audio equipment, making it an excellent choice for professional audio systems in live sound, installed sound, and recording studio settings.
