An electrical distribution system that provides a modular arrangement for power and signal distribution in a motor vehicle includes a power distribution circuit board connected to a power supply and to at least one electrical load, switch and control circuit boards electrically connected with the power distribution board via fuses or circuit breakers, and signal distribution devices mounted on the switch and control boards for transmitting control signals between the switch and control boards. The power distribution board includes switching devices for electrically coupling the power supply to the electrical load, the control board has a processor for controlling the operation of the switching devices based on signals received via an external connector.

Electrical distribution system

A radio with a tuner and other program sources uses a digital signal processor (DSP) to enhance the audio signal and to generate a stream of digital data including audio data and control data corresponding to loudness functions. A fiber optic data link couples the data stream to a plurality of remote DSP modules each of which drive one or more speakers. Each module contains a user programmed DSP, a digital to analog converter and an amplifier for each associated speaker. The DSP modules are identical except for software parameters which establish a transfer function and a loudness characteristic for each speaker. The same DSP modules and the same speakers can be used in several vehicle types and the system audio performance can be optimized by customizing software for each type of vehicle.
