Crown Audio CDi 4|300BL Analog + BLU link input, 4 channel Power Amp

The CDi DriveCore Series is an evolution in amplification, providing an impressive mix of high-performance; rich feature set, and competitive cost. Using technology derived from our flagship Installed Sound amplifier (Crown DriveCore Install series), the CDi DriveCore 4|300BL offers streamlined functionality to work in almost any small/medium sized installation such as restaurants, retail stores, and more. Designed for ease-of-use in a variety of applications, the 4|300BL is a 4-channel amp that includes network control/monitoring, high-level DSP, front-panel interface, and support for driving up to 100Vrms speaker loads without requiring a transformer. The 4|300BL also comes with BLU link, adding the ability to send and receive channels over HARMAN’s digital audio BUS. The entire CDi DriveCore line comes pre-loaded with JBL speaker tunings to help make installations quicker and easier.

Features

• DriveCore Technology – Crown’s proprietary DriveCore technology eliminates hundreds of components within each amplifier, reducing the variability of component values, increasing reliability, resulting in incredible audio fidelity from an efficient design.
• Network Control and Monitoring – Through Harman’s HiQnet Audio Architect software, the CDi DriveCore can be controlled, configured, and monitored through standard TCP/IQ network.
• DSP – On-board Digital Signal Processor in each amplifier allows for custom configuration
• Input Router
• Input Delay – Up to 1000ms
• Input Parametric EQ – 8 band
• Crossover
• Output Parametric EQ – 8 band
• Output Delay – Up to 100ms
• LevelMAX™ Limiter
• BLU link (BL models only) – Both receive and send channels over HARMAN’s 256 channel, fault-tolerant audio BUS, BLU link
• Direct Drive 70/100Vrms Output – Each output channel is capable of provide either 70V or 100V for high impedance applications.
• Front-Panel Interface – Completely configure the amplifier using an intuitive front-panel interface.
• GPIO/AUX Port – Recall presets, mute channels, monitor faults, power on/off the amplifier, and more through a combined GPIO/AUX Port.
