Product Overview
The Crown CDi 4000 is a two-channel commercial install amplifier delivering 1200W per channel at 4 ohms with direct 70V and 140V outputs. Transformerless constant-voltage drive at this power level is what lets one amplifier feed a long line of speakers across a large venue without the weight, cost, or insertion loss of an output transformer.
