Crown CT 875 ComTech DriveCore Amplifier

The CT 875 carries 8 channels of 75 W and cools by convection, so there is no fan to clog, whine, or fail in a rack that sits inside a occupied room. Crown's DriveCore output stage folds the drive circuitry into the power stage, which is what lets this much channel count fit a chassis this shallow.

Flexible input routing lets one source feed several outputs, useful when a paging or background-music signal has to land on multiple zones. A universal power supply covers whatever mains the building provides, and integrated life-safety features suit it to installs that have to keep working when the rest does not.
