The control matrix can be used to multiply the input by a factor of -20 to 20 with an increment of 0.1 (-10, 10), or 1 [-20, 10]∪[10, 20]. This can be effectively used to apply input gain, or invert the input.
For instance, the signal can be scaled down by setting the first element in the Control matrix to 0.1. As a result, the 49.992 mV input signal is reduced to 5.0794 mV by the Control matrix.
Additionally, the signal can be reversed and scaled to -499.992 mV by setting the Control matrix to -10.
