Bass Cut Filter; Enhancer; Input; Expander - Roland BR-900CD Owner's Manual

Mastering Tool Kit Parameter Functions

Bass Cut Filter

This is a filter that cuts unwanted low range noise, such as pops.
On/Off
This setting turns the Bass Cut Filter on/off.
Freq
This sets the frequency containing popping or other undesirable
lower-range noises that you want to cut.

Enhancer

This adds more liveliness to the sound, putting sounds at the
forefront.
On/Off
This parameter turns the enhancer effect on/off.
Sens
This sets the amount of Enhancer that is applied.
Freq
Sets the frequency at which the enhancer effect will begin to be
applied.
Mix Lvl
Sets the volume of the effect sound.

Input

This divides the original sound into three frequency ranges: low,
mid, and high.
Gain
Sets the overall volume level before the signal passes through the
expander/compressor.
Dly Time
This sets the amount of time by which the source input sound is
delayed.
SplitL
This sets the frequency (in the lower range) at which the source
sound is split into three separate ranges.
SplitH
This sets the frequency (in the upper range) at which the source
sound is split into three separate ranges.
106

Expander

This expands the dynamic range at a fixed ratio.
On/Off
OFF, ON
This setting turns the expander on/off.
Lo Thres
20 Hz–2.0 kHz
This sets the volume level at which the lower-range expander goes
into effect.
Lo Ratio
This sets the ratio of increase in output of the lower range when the
input level falls below the Lo threshold level.
Lo Attack
This sets the time it takes for the lower-range expander to go into
OFF, ON
effect once the input level falls below the Lo threshold level.
Lo Release
0–100
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
1.0–10.0 kHz
This sets the volume level at which the midrange expander goes into
effect.
Mid Ratio
-24– +12 dB
This sets the ratio of increase in output of the midrange when the
input level falls below the Middle threshold level.
Mid Attack
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
-24– +12 dB
This sets the time it takes for the midrange expander effect to stop
once the input level exceeds the Middle threshold level.
Hi Thres
0–10 ms
This sets the volume level at which the upper-range expander goes
into effect.
Hi Ratio
20–800 Hz
This sets the ratio of increase in output of the upper range when the
input level falls below the Hi threshold level.
Hi Attack
1.6–16.0 kHz
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
This sets the time it takes for the upper-range expander effect to stop
once the input level exceeds the Hi threshold level.
