The input control is not a threshold control. The threshold is set internally, and the input control brings the signal level up to meet the threshold.
It's always best to start with the input at minimum, and bring it up until you see the amount of gain reduction you want on the meter. Then bring up the output to the level you want. Remember, these controls are marked for ATTENUATION. So "0" is the max level (no attenuation) and the infinity symbol is min level (full attenuation).
Typically, with circa +4dBu signal levels, you'll end up with the input knob somewhere between 9 and 11 o' clock, and the output knob somewhere between 12 and 2 o' clock.
Starting with the input maxed would blast the hell out of the input section and give you maximum gain reduction. If you want to start with no gain reduction, the input control must be very low.
You can also always modify the internally set threshold if you feel that you want more input level with less gain reduction.
