Front/rear car radio fader
Although most car radio/casse players produced in the past five years or so are fitted with a front/rear speaker volume control, there are still many about that have no such provision. A simple way of adding this facility is shown in this article, which is the principle on which many car radio faders operate. This arrangement gives a stepped front/rear speaker volume control with step ratios between 4: 1 and 1:4. (Many modern car radios have a continuously variable control, however, Editor).
