Crown CDi 4300BL DriveCore Power Amplifier 1200W + BLU Link 2U *B-STOCK*

Description

Used briefly, fully tested and working.

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.
