Step IV. Match the High-pass and Low-pass Filter Levels

This section explains how, once the programmable electronic crossover has been configured, to match the high-pass and low-pass filter levels using the Master Reference Subwoofer’s built-in noise generator.

Step A describes muting the low-pass filter while adjusting the high-pass flter level. Step B describes muting the high-pass filter while adjusting the low-pass filter level.
