22Mastering Tools parameter list

●COMP (Compressor) *2: Compressor the entire output signals when the input volume exceeds a specified value.

Effect On/Off (Effect On/Off) OFF, ON This parameter turns the compressor effects on/off.
Low Threshold (Low Threshold) -24–0 dB This parameter sets the volume at which the compressor for the low
frequency band starts working.
Mid Threshold (Middle Threshold) -24–0 dB This parameter sets the volume at which the compressor for the middle
frequency band starts working.
Hi Threshold (High Threshold) -24–0 dB This parameter sets the volume at which the compressor for the high
frequency band starts working.
Low Ratio (Low Ratio) 1:1.0–1:16.0, 1:INF This parameter sets the ratio at which the output in the low frequency band
is suppressed when the input level has exceeded the low threshold level.
Mid Ratio (Middle Ratio) 1:1.0–1:16.0, 1:INF
This parameter sets the ratio at which the output in the middle frequency band
is suppressed when the input level has exceeded the middle threshold level.
High Ratio (High Ratio) 1:1.0–1:16.0, 1:INF
This parameter sets the ratio at which the output in the High frequency band is
suppressed when the input level has exceeded the High threshold level.
Low Attack (Low Attack) 0–100 ms
This parameter sets the time until when the low frequency band compressor
starts working after the input level has exceeded the low threshold level.
Mid Attack (Middle Attack) 0–100 ms
This parameter sets the time until when the middle frequency band compressor
starts working after the input level has exceeded the middle threshold level.
High Attack (High Attack) 0–100 ms
This parameter sets the time until when the High frequency band compressor
starts working after the input level has exceeded the High threshold level.
Low Release (Low Release) 50–5000 ms
This parameter sets the time until when the low frequency band compressor
stops working after the input level has dropped below the low threshold level.
Mid Release (Middle Release) 50–5000 ms

This parameter sets the time until when the middle frequency band compressor

stops working after the input level has dropped below the middle threshold level.

High Release (High Release) 50–5000 ms
This parameter sets the time until when the High frequency band compressor
stops working after the input level has dropped below the High threshold level.

●MIX (Mixer): Adjust the volume of the low, mid, and high frequency ranges, and mix them.

Low Level (Low Level) -80–+6 dB This parameter sets the volume in the low frequency band after passing
through the expander and compressor.
Mid Level (Middle Level) -80–+6 dB This parameter sets the middle frequency band volume after passing
through the expander and compressor.
High Level (High Level) -80–+6 dB This parameter sets the volume in the High frequency band after passing
through the expander and compressor.

●LMT (Limiter): Prevents distortion by suppressing signals at High levels.

Effect On/Off (Effect On/Off) OFF, ON This parameter turns the limiter effects on/off.
Threshold (Threshold) -24–0 dB This parameter sets the volume at which the limiter starts working.
Attack (Attack) 0–100 ms This parameter sets the time until when the limiter starts working after the
input level has exceeded threshold level.
Release (Release) 50–5000 ms This parameter sets the time until when the limiter stops working after the
input level drops below the threshold level.

●OUT (Output): Provides settings concerning overall output.

Level (Level) -80– +6 dB This parameter sets the overall volume after passing through the limiter.
Soft Clip (Soft Clip) OFF, ON By turning this ON, suppresses conspicuous distortion that may occur
when the effect of compressor/limiter has been applied excessively.
Dither (Dither) OFF, 8–24 bit This parameter smooths the transition where the sound disappears.
*1 If “Low Type” or “High Type” is set to “SHELV” (Shelving Type), the setting for “Lo Q “or “High Q” is invalid.
*2 With Compressor (COMP), the level is automatically adjusted to the optimal with the settings for “Threshold” and “Ratio”. Setting
“Attack” to a relatively long time may cause distortion. For this reason, a margin of -6 dB is provided. Adjust the Mixer (MIX) level as
required.
