Mastering Tool Kit Parameter Functions
Section 4
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.
