About Crown Audio CDi 4|300BL

Discover the CDi DriveCore Series 4-Channel 300W Professional Power Amplifier, a pinnacle of audio amplification that blends high-performance capabilities with a rich feature set, all at a competitive cost. Drawing on the advanced technology of our flagship Crown DriveCore Install series, the CDi DriveCore 4|300BL is engineered to excel in a wide range of small to medium-sized installations, including restaurants, retail stores, and beyond.

This professional-grade amplifier is designed for seamless integration and ease of use across various applications. As a 4-channel amplifier, it boasts network control and monitoring, high-level digital signal processing (DSP), and a user-friendly front-panel interface. It is adept at driving up to 100Vrms speaker loads directly, eliminating the need for transformers and simplifying the setup process.

The inclusion of BLU link technology enhances this amplifier's capabilities, allowing it to send and receive audio channels over HARMAN's robust digital audio BUS, ensuring seamless network audio compatibility and integration with other audio devices and systems.

Crown's proprietary DriveCore technology is at the heart of the CDi DriveCore 4|300BL, significantly reducing the number of components within the amplifier. This not only increases reliability but also ensures exceptional audio fidelity through an efficient and streamlined design.

With Harman's HiQnet Audio Architect software, users gain unparalleled control over the CDi DriveCore, with the ability to configure and monitor the system through a standard TCP/IQ network. The onboard DSP in each amplifier allows for custom configurations and includes a suite of integrated features such as input routing, input delay up to 1000ms, 8-band input parametric EQ, crossover functions, 8-band output parametric EQ, output delay up to 100ms, and the LevelMAX Limiter for optimal sound management.

Each output channel of the CDi DriveCore 4|300BL can provide either 70V or 100V, catering to high impedance applications with ease. The front-panel interface offers complete configuration of the amplifier, while the combined GPIO/AUX Port allows for recalling presets, muting channels, monitoring faults, and power cycling with convenience.

Pre-loaded with JBL speaker tunings, this amplifier is designed to streamline installations, making the setup process quicker and easier for users. The CDi DriveCore Series 4-Channel 300W Professional Power Amplifier is not just powerful and advanced; it is also a durable and high-quality solution for professional audio systems that demand the best in sound reproduction and system integration.
