A vehicle audio system includes overhead speakers connected to an audio source through a control circuit. The control circuit effects signal delays, crossover filtering, and equalization. The overhead speakers are connected to the control circuit and are positioned such that they provide strong front staging and desired surrounding ambiance responsive ...

Audio transmission systems are the means by which audio signals are routed, processed, and assigned to the desired monitor and recording output channels. In the early days of electrical recording, rarely more than one or two microphones were used, and the signal routing was to a single output channel. (The terms “line out” and output bus’ are also used
