Algorithm List
Dual Compressor/Limiter
Compressors suppress signals at High levels. Limiter is used to control excessive input. Each of the above is used to prevent sound
distortion or to control dynamics.
fig.08-40
Input A is input into the L-channel side of the effect. Therefore, it is required to insert and connect “Lch” of the effect to the channel handling Input A. Similarly,
Input B is input into the R-channel side of the effect. Insert and connect “Rch” of the effect to the channel handling Input B.
Parameter (full name) Setting Function
CmpA, CmpB (Compressor): Compresses the entire output signals when the input volume has exceeded a preset value.
(Limiter): Suppresses the volume of the section where the input volume has exceeded the preset value.
Sw (Switch) On, Off Turns the compressor/limiter on or off.
Thrsh (Threshold Level) -60 - 0 dB Sets the level at which the compressor/limiter starts taking effect.
Ratio (Ratio) 1.5:1, 2:1, 4:1, 100:1 Sets the compression ratio applied when threshold level (Thresh) is exceeded.
Attack (Attack Time) 0–100 Sets the time from when the input level exceeds the threshold level to when the effect begins to
apply.
Release (Release Time) 0–100 Sets the time from when the input level drops below the threshold level to when the effect ceases
to apply.
Level (Output Level) -60–12 dB Sets the volume of the compressor/limiter sound.
Detect (Detect In) A, B, Link Selects Input A or B for controlling compressor/limiter. Set this to “Link” for controlling by the
input at a greater level.
NS (Noise Suppressor): Mutes noise in the silent mode.
Sw (Switch) On, Off Turns the noise suppressor on or off.
Thresh (Threshold) 0–100 Sets the level to start muting noise.
Release (Release) 0–100 Sets the time over which the volume will drop to 0 after the noise starts being muted.
Detect (Detect In) A, B, Link Selects the input (Input A/Input B) for controlling Noise Suppressor. Set this to “Link” for
controlling by the input at a greater level.

Difference between Compressor and Limiter
Behaviors of Compressor and Limiter are very similar. Both of them compress the entire output signals if input signals exceed
a certain level (threshold level), according to the input level.
Compressor automatically drops the amplitude to suppress all levels in the exceeding section. Limiter suppresses only the
maximum level of input signals.
●
Using as Limiter
• Threshold Level (Thresh): Relatively High
• Ratio (Ratio): 100:1
• Attack Time (Attack): Relatively short
• Release Time (Release): Relatively short
● Using as Compressor
• Threshold Level (Thresh): A level that does not cause distortion of output sounds.
• Ratio (Ratio): 1.5:1, 2:1, 4:1
• Attack Time (Attack): Adjusted according to the input sound type.
• Release Time (Release): Adjusted according to the input sound type.
