III and FM3 or FM9 and FM3?

[francis]

Where did you get this information from?

There is also a secret sauceIV in the fm3 instrument input. This is specified on page 2 of the fm3 manual.

I think what AlGrenadine was trying to say was that the input variable/auto impedance function is not present in FM3. (FM3 = 1 Mohm fixed input impedance)
