Crown CDi 4000 Install Amplifier

The CDi 4000 runs 1200 W per channel at 4 ohms with the same 70V/140V constant-voltage switching as the rest of the CDi line, sized for a large distributed system: a big-box retail floor, a stadium concourse, or a campus paging network with a heavy speaker tap load. Onboard crossovers, EQ, delay, and output limiting cover system tuning with up to 20 user-defined presets.

A front-panel LCD screen configures the amp without a laptop, and balanced or unbalanced inputs bring in a house mixer or a central paging source directly. The 2RU chassis and switch-mode power supply keep it install-rack friendly at a power level that would otherwise need a bigger box.
