<p>An output circuit for balanced amplifiers connected to one terminal of each of two loudspeakers with the other terminal of each loudspeaker connected together to the arm of a double-throw switch to make contact either with a terminal connected to the first terminal of one load to short circuit that load while applying signals from the amplifiers differentially to the other load, or to connect the second terminals of each of the loudspeakers to a common signal output terminal of the amplifiers so that each load is connected across a respective amplifier output circuit.</p> |
