Sound system switching device, esp. for car stereo equipment

摘要

The switching device (3) is controlled by a microprocessor (5) and coupled to a set of low frequency amplifiers (4). The switching device simultaneously enables a connection to all low frequency signal sources of the audio devices (radio, cassette, CD, MD, external device), or just individual low frequency signal sources, as well as a connection to all audio outputs or just individual outputs. The distribution of the individual low frequency signal sources of the audio devices at the audio outputs is selectable via a switch on the operating panel which activates the microprocessor. A menu or several buttons may be provided on the operating panel.
