CRO CDi 4|1200BL


Analog + BLU link input, 4 channel, 1200W per output channel


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|1200BL offers streamlined functionality to work in almost any large sized installation such as cinema, houses of worship, hotels, cruise lines, and more.  Designed for ease-of-use in a variety of applications, the 4|1200BL 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|1200BL 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.
