Abstract

PURPOSE:To remove cross talk during double sound broadcast reception by opening a switch circuit for wide effect when a control channel signal shows double sound broadcast. CONSTITUTION:During stereo broadcast reception, analog switches 10 and 11 are both closed to feed a 1st channel signal back to a transmission line for a 2nd channel signal and the 2nd channel signal back to that for the 1st channel signal as much as fixed values respectively, thereby displaying wide effect. During double sound broadcast reception, on the other hand, analog switches 10 and 11 are opened to stop cross talk from appearing on party-side channel transmission lines through impedance circuits 12 and 13.
