Figure 29: LOW CUT function
All the input channels can be controlled in the "LOW CUT" mode.
Figure 30: Adjustment range for the function
The "LOW CUT" function suppresses low-frequency interference noise. The low cut filter is
designed as a second order high-pass filter. The cut-off frequency can be raised by turning
the rotary knob in a clockwise direction and lowered by turning it counter-clockwise.
The settings range from 0 Hz (no effect) to 150 Hz (severe attenuation). One LED is illuminated
at 0 Hz, while the entire LED ring is illuminated at 150 Hz.
