Roland VS-1680 owner manual BCut Bass-cut filter, Enh Enhancer, Input, Exp Expander

New effects algorithms

BCut (Bass-cut filter)	fig.3-04
This removes unwanted low-frequency components, such as	Level	L-SplitP	H-SplitP
pop noise.
Sw (Switch) Off, On	Low	Mid	High

Turns the bass-cut filter on/off.

Freq (Frequency) Thru, 20–2,000Hz Freq

Adjusts the cutoff frequency of the bass-cut filter.

Enh (Enhancer)

This effect adds a phase-shifted signal to the original signal, enhancing the presence of the sound, and bringing it to the foreground.

Sw (Switch) Off, On

Turns the enhancer on/off.

Sens (Sensitivity) 0–100

Adjusts the degree to which the enhancer will respond to the volume of the input signal.

Freq (Frequency) 1.0–10.0kHz

Adjusts the frequency at which the enhancer will begin to take effect. The effect is applied at frequencies above the specified value.

MixLvl (Mix level) -24–+12dB

Adjusts the amount of effect sound that will be added to the original sound.

In (Input)

The input signal is divided into three parts by frequency band.

InputG (Input gain) -24–+12dB

Adjusts the overall volume level of the signal before it enters the expander (Exp) and compressor (Cmp).

D-Time (Detect time) 0–10ms

If the original signal is slightly delayed before being input, the expander/compressor will be able to use more processing time, and can adjust the level more appropriately. Adjusts the time by which the original signal is delayed. The output signal from the Mastering Tool Kit is delayed by the time set here.

L-SplitP (Low split point) 20–800Hz H-SplitP (High split point) 1.6–16kHz

Specify the frequencies at which the original signal will be split into three parts.

Exp (Expander)

This effect restricts the output by a specific ratio when low- level signals are input.

Out	Threshold
1:1	1:2	In
Ratio

Sw (Switch) Off, On

Turns the expander on/off.

Low Thre (Low threshold) -80–0dB Mid Thre (Middle threshold) -80–0dB High Thre (High threshold) -80–0dB

Specify the level at which the expander will begin to take effect.

Low Ratio 1:1–1:16, 1:INF

Mid Ratio 1:1–1:16, 1:INF

High Ratio 1:1–1:16, 1:INF

Adjust the ratio by which the output is restricted when the input level is below the threshold level.

Low Atck (Low attack) 0–100ms Mid Atck (Middle attack) 0–100ms High Atck (High attack) 0–100ms

Adjust the time from when the input level falls below the threshold level until the expander begins to take effect.

Low Rel (Low release) 50–5,000ms Mid Rel (Middle release) 50–5,000ms High Rel (High release) 50–5,000ms

Adjust the time from when the input level exceeds the

threshold level until the expander effect is bypassed.
