Description
The CA-4000 tops our CA Series: a two-channel power amplifier built to run stage subwoofers and full-range cabinets hard, night after night. Each channel delivers 1600 W into 4 Ω, rising to 2800 W when bridged into a single load.
Rear-panel switches select stereo, bridge or parallel operation, and a built-in low-cut / subwoofer filter with adjustable frequency lets you split a system without outboard processing. Protect, Clip, Active and Status lights for each channel on the front panel make it easy to see what the amp is doing from the mixing position.
