Zoom R20 - Using Compressor, Limiter, and Gate

Using the Comp/Limiter/Gate function
The volume can be adjusted suitably according to input signal levels and unwanted noise can be cut,
making the sound clearer.
• Comp
The compressor reduces level differences between loud and quiet sounds, making the sound clearer.
• Limiter
The limiter can prevent distortion by reducing input signals that have high levels.
• Gate
This cuts input signals with low levels, reducing background noise.

The compressor and limiter lower input signals with high levels according to the parameter adjustments
shown below. The limiter has a stronger effect compared to the compressor. The gate cuts input signals
with low levels according to the parameter adjustments shown below.

Parameter Explanation
Threshold Comp/Limiter: This adjusts the input level that activates the
effect. When the input level exceeds the threshold, the excess
level is compressed with a ratio of 1:4 for Comp and 1:20 for
Limiter.
Gate: This adjusts the input level that deactivates the effect.
Sound below the threshold level will not be output.
