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 operation over a standard TCP/IQ network. The rear panel includes terminal block inputs and barrier strip outputs. he Crown CDi 2000 Two Channel Commercial Amplifier is a rugged, lightweight commercial power amplifier designed for dual-channel or bridge-mono operation in installed audio applications such as restaurants, retail stores, warehouses, offices, and more. The CDi 2000 provides accurate, uncolored sound with low distortion for excellent music and vocal reproduction. It delivers 800W per channel at 4 Ohms, and supports multiple low-impedance configurations, as well as 70V and 140V constant-voltage systems. The switch-mode universal power supply enables safe operation across the globe. Advanced protection circuitry guards against shorted outputs, open circuits, DC, mismatched loads, general overheating, high-frequency overloads and internal faults. The CDi 2000 also has integrated DSP presets for adjustable crossover frequencies, EQ, limiting, compression, delay, and a subharmonic synthesizer. A backlit LCD displays relevant information. The removable Euroblock inputs and barrier strip outputs accommodate a variety of system setups.
