Vehicle power amplifier and voltage supply thereof

摘要

A voltage supply for a vehicle power amplifier having an audio property compensation function. The voltage supply includes means for setting the voltage supply to a first mode when its power is turned on, and means for setting the voltage supply to a second mode when its power is tuned on after setting on/off operation of compensation functions and associated adjustment values in the first mode and turning the power off, wherein the first mode is to supply voltage only to a unit for setting the compensation functions and values, and the second mode is to supply power to the entire vehicle power amplifier.
