New effects algorithms

Cmp (Compressor)

When a high-level signal is input, this effect restricts the output at a specified ratio.

fig.3-06
Out	Threshold
	1:1
	1:2
	1:INF
	Ratio
	In

Sw (Switch) Off, On

Turns the compressor on/off.

Low Thre (Low threshold) -24–0dB Mid Thre (Middle threshold) -24–0dB High Thre (High threshold) -24–0dB

Specify the level at which the compressor 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 will be restricted when the input level exceeds 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 exceeds the threshold level until the compressor takes 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 falls below the threshold level until the compressor no longer has an effect.

NOTE

The compressor provides threshold (Thre) and Ratio settings that automatically adjust a signal to the optimal level. Since lengthening the attack (Atck) may cause distortion, a -6 dB margin is provided. Adjust the mixer (Mix) level as necessary.

Mix (Mixer)

Adjusts the volume for each of the three frequency bands that were divided.

Low Lvl (Low level) -80–+6dB

Mid Lvl (Middle level) -80–+6dB

High Lvl (High level) -80–+6dB

These adjust, for each band, the volume level of the signal that has passed through the expander (Exp) and compressor (Cmp).

Lmt (Limiter)

This effect restricts excessive input levels.

Sw (Switch) Off, On

Turns the limiter on/off.

Thresh (Threshold) -24–0dB

Specifies the level at which the limiter will begin to operate.

Attack 0–100ms

Adjusts the time from when the input level exceeds the threshold level until when the limiter begins to operate.

Release 50–5,000ms

Adjusts the time from when the input level falls below the threshold level until the limiter no longer has an effect.

Out (Output)

Make settings related to the overall output.

Soft Clip Off, On

This quiets unwanted distortion that occurs when the compressor or limiter effect is applied in an extreme fashion.
