Bass Cut Filter; Enhancer; Input; Expander - Boss BR-1180 Owner's Manual

High Q
Sets the frequency response curve steepness for the upper
range's center frequency. (*1)
Output Level
Sets the overall volume level after equalization.
(*1) The Low Q/Hi Q setting is disabled when "SHELVNG"
(shelving type equalization) is selected for the Low Type or
High Type.

Bass Cut Filter

This is a filter that cuts unwanted low range noise, such as
pops.
Effect On/Off
This setting turns the Bass Cut Filter on/off.
Cut Off Freq
This sets the frequency containing popping or other
undesirable lower-range noises that you want to cut.

Enhancer

This adds more liveliness to the sound, putting sounds at the
forefront.
Effect On/Off
This parameter turns the enhancer effect on/off.
Sensitivity
This sets the amount of Enhancer that is applied.
Frequency
Sets the frequency at which the enhancer effect will begin to
be applied.
Mix Level
Sets the volume of the effect sound.

Input

This divides the original sound into three frequency ranges:
low, mid, and high.
Input Gain
Sets the overall volume level before the signal passes through
the expander/compressor.
Delay Time
This sets the amount of time by which the source input
sound is delayed.
Split Freq L
This sets the frequency (in the lower range) at which the
source sound is split into three separate ranges.
Split Freq H
This sets the frequency (in the upper range) at which the
source sound is split into three separate ranges.

Expander

This expands the dynamic range at a fixed ratio.
Effect On/Off
This setting turns the expander on/off.
ExpL: Thres
This sets the volume level at which the lower-range expander
goes into effect.
ExpL: Ratio
This sets the ratio of increase in output of the lower range
when the input level falls below the Lo threshold level.
ExpL: Attack
This sets the time it takes for the lower-range expander to go
into effect once the input level falls below the Lo threshold
level.
ExpL: Release
This sets the time it takes for the lower-range expander effect
to stop once the input level exceeds the Lo threshold level.
ExpM: Thres
This sets the volume level at which the midrange expander
goes into effect.
ExpM: Ratio
This sets the ratio of increase in output of the midrange when
the input level falls below the Middle threshold level.
