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.

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.

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.
