Boss Audio Systems BR-900CD owner manual Bass Cut Filter, Input, Expander, 106

Mastering Tool Kit Parameter Functions

Bass Cut Filter

This is a filter that cuts unwanted low range noise, such as pops.

On/Off OFF, ON

This setting turns the Bass Cut Filter on/off.

Freq 20 Hz–2.0 kHz

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 OFF, ON

This parameter turns the enhancer effect on/off.

Sens 0–100

This sets the amount of Enhancer that is applied.

Freq 1.0–10.0 kHz

Sets the frequency at which the enhancer effect will begin to be applied.

Mix Lvl -24– +12 dB

Sets the volume of the effect sound.

Input

This divides the original sound into three frequency ranges: low, mid, and high.

Gain -24– +12 dB

Sets the overall volume level before the signal passes through the expander/compressor.

Dly Time 0–10 ms

This sets the amount of time by which the source input sound is delayed.

SplitL 20–800 Hz

This sets the frequency (in the lower range) at which the source sound is split into three separate ranges.

SplitH 1.6–16.0 kHz

This sets the frequency (in the upper range) at which the source sound is split into three separate ranges.

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.
