To use the SCM268 with a Blonder Tongue modulator MAVM-860 do I set the mic/line out to line level due to the mavm having a RCA inputjack? Also,there is going to be a need for future internal television systems of a situation in which there is going to be a single forward channel to output a switchable video signal between two each return channels. if using the SCM268, with a video selector, whereas, two voices can be heard while a single video source is selceted, how can both locations here each other and yet not create back feed on the system?Please provide the electrical specifications for the Blonder Tongue modulator MAVM-860 RCA input jack: required signal level, and impedance.
The SCM268 will not work for your second scenario. You require a video/audio switcher with audio follow video capability. Shure does not make such a product. Radio Shack offers simple video/audio switchers.
