120Hz to Full
Sets the frequency above which a low–pass filter attenuates both the reverberation and the early reflections. The overall low–pass filtering is actually a combination of the parameters High Frequency and High Shelf (HIS). This parameter is important for creating a realistic and natural reverberation. Typical values are 2kHz to 4kHz.
This is a continuous parameter on LX480, which interpolates between the discrete values found on the original hardware.
