The CA-5100 is a 5 x 100W model, based on the circuit topologies developed for the CA-5200 and other Delta series amplifiers. One large toroidal transformer with three secondary windings provides power supplies for left front and rear, right front and rear, and center channel audio circuits. Features including balanced and single-ended inputs, control and protections circuits are common to those on other Delta series amplifiers.

What's included in the box
