ABSTRACT:
A multiple output transformer network for a high-fidelity sound reproducing system which includes a high-frequency speaker and a low-frequency speaker, first and second output transformers, a high frequency by-pass filter coupling the secondary of the first output transformer to the high frequency speaker, and a low-frequency by-pass filter coupling the secondary of the second transformer to the second speaker, all mounted in a remote speaker unit. The by-pass filters have predetermined crossover characteristics. The primary windings of the transformers are connected to the output amplifier of the sound reproducing equipment by first and second extension leads.
