ABSTRACT:
When a stereophonic broadcasting signal is interrupted because an electric field has weakened, a pilot signal 1 which designates that the electric field is not strong enough to separate an R-channel signal and an L-channel signal from a signal received by the tuner, is also interrupted. This interruption of the pilot signal changes gains and/or phases which act on an R-channel signal and/or an L-channel signal which are applied to a sound field calibrating system.
