Transmitting a mono–compatible stereo television signal is, and will remain,
critical for broadcasters since most viewers have monaural receivers. The 760A
pattern display and the L+R bar indicate the fitness of your audio for monaural
reception. Figures 2–7 and 2–8 show, respectively, a stereo signal well suited for
monaural reception and a stereo signal unsuited for monaural use due to its large
L=–R (out–of–phase) component.

Routing audio through a complex studio presents many opportunities to
introduce polarity reversals. Any time a polarity reversal occurs, the 760A can
be used to trace the problem back to its source quickly. By introducing a sine
