Mastering Tool Kit Parameter Functions

Expander

This expands the dynamic range at a fixed ratio.

On/Off	OFF, ON
This setting turns the expander on/off.
Lo Thres	-80–0 dB

This sets the volume level at which the lower-range expander goes into effect.

Lo Ratio 1:1.00–1:16.0, 1:INF

This sets the ratio of increase in output of the lower range when the input level falls below the Lo threshold level.

Lo Attack 0–100 ms

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.

Lo Release 50–5000 ms

This sets the time it takes for the lower-range expander effect to stop once the input level exceeds the Lo threshold level.

Mid Thres -80–0 dB

This sets the volume level at which the midrange expander goes into effect.

Mid Ratio 1:1.00–1:16.0, 1:INF

This sets the ratio of increase in output of the midrange when the input level falls below the Middle threshold level.

Mid Attack 0–100 ms

This sets the time it takes for the midrange expander to go into effect once the input level falls below the Middle threshold level.

Mid Release 50–5000 ms

This sets the time it takes for the midrange expander effect to stop once the input level exceeds the Middle threshold level.

Hi Thres -80–0 dB

This sets the volume level at which the upper-range expander goes into effect.

Hi Ratio 1:1.00–1:16.0, 1:INF

This sets the ratio of increase in output of the upper range when the input level falls below the Hi threshold level.

Hi Attack 0–100 ms

This sets the time it takes for the upper-range expander to go into effect once the input level falls below the Hi threshold level.

Hi Release 50–5000 ms

This sets the time it takes for the upper-range expander effect to stop once the input level exceeds the Hi threshold level.

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 (Mix) level as needed.
