Also it would be of use to know the circuit schematic for the electronics
feeding the input.
However having said that, I can't see how you can reliably use the MAX197
for sampling voice or anyother signal > half the the Kernel HZ value.
Timing for the sampes will not be accurate enough, even though sampling
one input only, one can get sampling rates of upto 50K samples/sec (If my
memory if correct).
