Pole/Zero Matching and “Wrap Around”
When the monitor output is processing large signals, the output may “wrap around” as
the signal reaches the maximum level. Often a clamp box such as the LB1502 can still
be used to make the pole zero adjustment (see Figure 31, where the gain has been ad-
justed to produce “wrap around”).
