AB  - With the imminent reality of multichannel television sound (MTS) braodcasting, there is an urgent need to resolve some of the concerns frequently posed by broadcast engineers with regard to: 1) the spatial qualities of the M/S miking technique, and 2) the practicality of implementing the sum-and-difference (rather than the discrete left/right) mode of transmitting the stereo program signals throughout the broadcast plant. This paper will demonstrate the effective channel separation realized in a real-world situation, by recording on a working television studio set a sound source at various angles about an M/S microphone array, logging and tabulating the signal levels for M (L + R) and S (L - R), and then plotting the resultant signal levels for L and R for each of the angular locations. The authors will then demonstrate that the potential for down-line degradation of the original stereo program is minimized by implementing the sum-and-difference transmission mode.
