Mastering Tool Kit Parameter Functions
Section 3
Compressor
This compresses the overall output signal when the input volume
level exceeds a set value.
On/Off OFF, ON
This parameter turns the compressor effect on/off.
Lo Thres -24–0 dB
This sets the volume level at which the lower-range compressor goes
into effect.
Lo Ratio 1:1.00–1:16.0, 1:INF
This sets the ratio of suppression of the lower-range output when the
input level exceeds the Lo threshold level.
Lo Attack 0–100 ms
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 50–5000 ms
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 -24–0 dB
This sets the volume level at which the midrange compressor goes
into effect.
Mid Ratio 1:1.00–1:16.0, 1:INF
This sets the ratio of suppression of the midrange output when the
input level exceeds the Middle threshold level.
Mid Attack 0–100 ms
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 50–5000 ms
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 -24–0 dB
This sets the volume level at which the upper-range compressor goes
into effect.
Hi Ratio 1:1.00–1:16.0, 1:INF
This sets the ratio of suppression of the upper-range output when
the input level exceeds the Hi threshold level.
Hi Attack 0–100 ms
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 50–5000 ms
This sets the time it takes for the upper-range compressor effect to
stop once the input level falls below the Hi threshold level.
* 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 -80– +6 dB
Sets the volume level of the lower range after the signal passes
through the expander and compressor.
Mid Level -80– +6 dB
Sets the volume level of the midrange after the signal passes through
the expander and compressor.
Hi Level -80– +6 dB
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 OFF, ON
Sets the limiter to ON or OFF.
Thres -24–0 dB
Adjust this as appropriate for the input signal from your bass.
Attack 0–100 ms
This sets the time it takes for the limiter to go into effect once the
input level exceeds the threshold level.
Release 50–5000 ms
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 -80– +6 dB
Sets the volume level of the overall sound after the signal passes
through the limiter.
Soft Clip Off, On
This suppresses noticeable distortion occurring with heavy use of
the compressor/limiter effect.
Dither OFF, 24–8 BIT
This prevents the action of muting sounds from being too noticeable.
