The transistors are valves which let the central pool of current flow from the power supply to the speaker behind them. So one pool of power, but multiple outlets. If you open all the valves at the same time the single power supply may not be able to feed them all.

The newer receivers with assignable channels, just have multiple speaker connectors behind one output device. A relay selects which connector gets the power.
