Bass Cut Filter
This is a filter that cuts unwanted low range noise, such as pops.
On/Off
OFF, ON
This setting turns the Bass Cut Filter on/off.
Freq
20 Hz–2.0 kHz
This sets the frequency containing popping or other undesirable
lower-range noises that you want to cut.
lower-range noises that you want to cut.
Enhancer
This adds more liveliness to the sound, putting sounds at the
forefront.
forefront.
On/Off
OFF, ON
This parameter turns the enhancer effect on/off.
Sens
0–100
This sets the amount of Enhancer that is applied.
Freq
1.0–10.0 kHz
Sets the frequency at which the enhancer effect will begin to be
applied.
applied.
Mix Lvl
-24– +12 dB
Sets the volume of the effect sound.
Input
This divides the original sound into three frequency ranges: low,
mid, and high.
mid, and high.
Gain
-24– +12 dB

Dly Time
0–10 ms
This sets the amount of time by which the source input sound is
delayed.
