Compressor; Mixer; Limiter; Output - Boss BR-600 Owner's Manual

Compressor

This compresses the overall output signal when the input
volume level exceeds a set value.
On/Off
This parameter turns the compressor effect on/off.
Lo Thres
This sets the volume level at which the lower-range
compressor goes into effect.
Lo Ratio
This sets the ratio of suppression of the lower-range output
when the input level exceeds the Lo threshold level.
Lo Attack
This sets the time it takes for the lower-range compressor to go
into effect once the input level exceeds the Lo threshold level.
Lo Release
This sets the time it takes for the lower-range compressor
effect to stop once the input level falls below the Lo
threshold level.
Mid Thres
This sets the volume level at which the midrange
compressor goes into effect.
Mid Ratio
This sets the ratio of suppression of the midrange output
when the input level exceeds the Middle threshold level.
Mid Attack
This sets the time it takes for the midrange compressor to go into
effect once the input level exceeds the Middle threshold level.
Mid Release
This sets the time it takes for the midrange compressor
effect to stop once the input level falls below the Middle
threshold level.
Hi Thres
This sets the volume level at which the upper-range
compressor goes into effect.
Hi Ratio
This sets the ratio of suppression of the upper-range output
when the input level exceeds the Hi threshold level.
Hi Attack
This sets the time it takes for the upper-range compressor to go
into effect once the input level exceeds the Hi threshold level.
Hi Release
This sets the time it takes for the upper-range compressor effect
to stop once the input level falls below the Hi threshold level.

Mastering Tool Kit Parameter Functions
* With the compressor, the level is automatically adjusted to the
optimum setting according to the threshold (Thres) and ratio
(Ratio) settings. In addition, since lengthening the attack
(Attack) setting may result in distortion, a buffer (margin) of
-6 dB is provided. Adjust the Mixer level as needed.

Mixer

Adjusts the volume of each frequency band.
Lo Level
Sets the volume level of the lower range after the signal
passes through the expander and compressor.
Mid Level
Sets the volume level of the midrange after the signal passes
through the expander and compressor.
Hi Level
Sets the volume level of the upper range after the signal
passes through the expander and compressor.

Limiter

This suppresses high-level signals to prevent distortion.
On/Off
Sets the limiter to ON or OFF.
Thres
Adjust this as appropriate for the input signal from your bass.
Attack
This sets the time it takes for the limiter to go into effect
once the input level exceeds the threshold level.
Release
Adjusts the time until when the limiter will turn off after the
input level falls below the threshold level.

Output

This makes settings that affect the overall output.
Level
Sets the volume level of the overall sound after the signal
passes through the limiter.
Soft Clip
This suppresses noticeable distortion occurring with heavy
use of the compressor/limiter effect.
Dither
This prevents the action of muting sounds from being too
noticeable.
