ABSTRACT:
A vehicle radio having a microprocessor based control has bass and treble tone controls and a fade control to produce digital settings. A tone adjusting arrangement compensates for the effect of fade change on perceived tone or frequency response. Tables of compensation values stored in a ROM and addressed by fade settings are used to change the nominal tone settings. The tone setting combined with the compensation value provides an adjusted or compensated tone value to maintain a consistent tone when fade is adjusted.
