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.
