TX6n/5n/4n Reference Manual 53
Adjusting the Input/Output LevelsOn the TXn amplifiers, the gain / input sensitivity is adjusted by the input level before A/D conversion. The adjust-
able gain range is the same for the TX6n/TX5n/TX4n models. Since the maximum output is different for each
model, the settable range for input sensitivity will differ for each model. The gain and input sensitivity are linked;
you may edit either one.
