What kind of input voltage range to the ADAT are we talking about? If I
wanted to use a +/-10 volt range (or 0-10 volt) do I need a divide by 10
into the ADAT and gain of 10 on the ADAT output?

I mean, what is the native voltage range of the ADAT recorder?

Thanks again for a valuable piece of information.

Hi Grant:

The original (black face) ADAT can accommodate +/- 5 volts, so you would
divide by 2 at the input, and amplify the output by a factor of 2 to allow
+/- 10 volt signals.  The Pangolin board used to modify the ADAT XT has on
board attenuators and opamps to perform the required level changes, because
the ADAT XT internally has a 0 to +5 volts signal range.

I'm going by memory on the signal levels, I'll try to double check this
information in the next day or so.
