Each "bug" is a fairly low level IR emitter. They're designed to be "taped" over the IR sensor eye of the equipment to be controlled. The BASE has a much stronger IR emitter, designed to send IR some 25 feet (ie. "spray" a bunch of devices similar to what the actual remote would do. The IR will penetrate and work the devices through glass doors, if that's what your cabinet has. If wood (or some other non-glass substance) doors are what you have you'd need to have a "bug" run from the base to each device being controlled. You can get "double-bug" cords. You can also use "Y" adapters to double the emitter plug ins available. A "Y" and 2 double-bug cords will give you 4 "bugs"/devices controlled.
