The 300WCrown Audio CDi 4|300 4-Channel DriveCore Series Power Amplifierutilizes technology derived from the flagship Crown DriveCore Install series amplifiers, providing an impressive mix of high-performance, rich feature set, and competitive cost. The CDi DriveCore 4|300 offers streamlined functionality for most small- to medium-sized installation such as restaurants, retail stores, and more.
The DriveCore integrated circuit eliminates hundreds of components within the amplifier, reducing the variability of component values and increasing reliability, resulting in remarkable audio fidelity from an efficient design. The 4-channel amplifier is simple to use and includes a network control & monitoring, an advanced DSP circuit, and an easy-to-use, front-panel interface.
The amplifier is capable of driving up to 100Vrms speaker loads without requiring a transformer and comes pre-loaded with JBL speaker tunings to help make installations quicker and easier. The CDi 4|300 features an Ethernet port for using HARMAN’s HiQnet Audio Architect software for configuration and outputs.
