Model CA1250 Page:5 Features and Functions AC Mains. The CA1250 comes configured to connect to 110V-120V/60Hz mains. For use with 220V-240V/50Hz mains set the rear panel Voltage Select switch to220V-240V (also, replace the T10.0AL/250V fuse with a T5.0AL/250V fuse). Front Panel 1.
4-ohm load would therefore be 2-ohms to a bridged amp and if the amplifier isn’t designed to run Safely into such a low impedance (which the CA1250 is not) damage may occur to the amplifier.

(Note: use only one type of source). For Bus outputs: These RCA connectors are simply in parallel with the Bus Inputs and enable you to interconnect the CA1250 with another CA1250 or amplifier. ( Note: only the Input Bus signals will be patched to Output).
Physical location and mounting 1. The CA1250 is convection cooled. That is, it depends on the natural free flow of air up through the slot perforations in the bottom plate, over the internal heat dissipating fins, then out the top cover, for adequate cooling.
