Crown CDi 4|300 Analog Input, 4-Channel, 300W Amplifier
Overview
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|300 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|300 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 entire CDi DriveCore line comes pre-loaded with JBL speaker tunings to help make installations quicker and easier.
Feature
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 and includes these integrated features:
- Input Router
- Input Delay – Up to 1000ms
- Input Parametric EQ – 8 band
- Crossover • Output Parametric EQ – 8 band
- Output Delay – Up to 100ms
- LevelMAXâ„¢ Limiter
- Direct Drive 70/100Vrms Output – Each output channel is capable of providing 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.
- Pre-loaded Speaker Tunings – For quicker and easier setup and installation.
- BLU link (BL models only) – Both receive and send channels over HARMAN’s 256 channel, fault-tolerant audio BUS, BLU link.
