Bass Cut Filter; Enhancer; Input; Expander - Boss BR-1200CD Owner's Manual

Mastering Tool Kit parameter functions

Bass Cut Filter

This filter cuts out vocal pop and other unwanted low-band
noise.
On/Off
This setting turns the Bass Cut Filter on or off.
Cut Off Freq
This parameter sets the frequency below which vocal pop and other
undesirable lower-range noises will be filtered out.

Enhancer

This effect makes a sound livelier, and thus, more present in the mix.
On/Off
This parameter turns the enhancer on or off.
Sensitivity
Sets the degree to which the enhancer is to be applied.
Frequency
Sets the frequency at which the enhancer will begin to affect the sound.
Mix Level
Sets the volume of the effect sound.

Input

This effect divides the original sound into three frequency
bands—namely, low, middle, and high.
Input Gain
Sets the overall volume level before the signal passes through the
expander/compressor.
Delay Time
This parameter sets the amount of time by which the input sound is delayed.
Split Freq L
Sets the low-band frequency at which the source sound is split into
low and middle bands.
Split Freq H
Sets the upper-band frequency at which the source sound is split into
middle and high bands.

Expander

This effect expands the dynamic range at a fixed ratio.
On/Off
This setting turns the expander on or off.
ExpL: Thres
This parameter sets the volume level at which the low-band
expander begins to affect the sound.
ExpL: Ratio
Sets the ratio for output increase in the low band when the input
level falls below the Lo threshold.
ExpL: Attack
Sets the time it takes for the low-band expander to start affecting the
sound once the input level falls below the Lo threshold.
ExpL: Release
Sets the time it takes for the low-band expander to stop affecting the
sound once the input level rises above the Lo threshold.
ExpM: Thres
This sets the volume level at which the midrange expander goes into
effect.
ExpM: Ratio
This parameter sets the volume level at which the middle-band
expander begins to affect the sound.
ExpM: Attack
Sets the time it takes for the middle-band expander to start affecting
the sound once the input level falls below the Middle threshold.
ExpM: Release
Sets the time it takes for the middle-band expander to stop affecting
the sound once the input level rises above the Middle threshold.
ExpH: Thres
This parameter sets the volume level at which the high-band
expander begins to affect the sound.
ExpH: Ratio
Sets the ratio for output increase in the high band when the input
level falls below the Hi threshold.
ExpH: Attack
Sets the time it takes for the high-band expander to start affecting the
sound once the input level falls below the Hi threshold.
ExpH: Release
Sets the time it takes for the high-band expander to stop affecting the
sound once the input level rises above the Hi threshold.
