"The switches on the MIC 2496 set these to a variety of combinations of 16 or 24 bit and from 38
to 192 kHz."
38K? Do you mean 32K?
And, the MIC2496 does not output 16 bits, no matter where the switches are. Running it into a 16-bit recorder will cause the least significant 8 bits to be truncated, ie. thrown away.
It outputs 24-bit, and then 44.1, 48, 88.2, or 96KHZ, depending on the switch positions. If you want 192KHZ, you'll need to open the unit up and move jumpers around.
