As the below drawing, when switch is OFF, the limit is off,
the limit circuit is out of work, if input signal is too strong,
output can cause clip distortion and also raise overload on
loudspeaker
As the below drawing, when the switch is ON, the limit is
on, if the input signal is too strong, the limit circuit can
control the gain and reduce the distortion, also control the
average output power, but it does not affect peak power,
protect the loudspeaker and assure the dynamic of music.
Note: Please set to "ON" position when using.
When LF cutting is at 50Hz,it equals discrete a 50Hz
high pass filter on input, the signal lower than 50Hz will
be accordingly attenuated, then can reduce the
noneffective swing and lower the distortion.
Like the right drawing:
When LF cutting is at 25Hz, it equals discrete a 25Hz
high pass filter on input circuit, it just attenuate the signal
lower than 25Hz.
Like the right drawing:
