Using the Digital Compressor
Limiter
A limiter prevents the signal from exceeding a preset level (threshold).
Signal levels below the threshold will be unaffected.
Set the controls as follows:
Threshold: Above, XX% (where XX is the limit point).
Ratio: >10:1
Attack Time: 1 mS
Release Time: approximately 100 mS
Musical Compression (e.g. Guitar)
This type of compression tries to keep the volume constant, generally
to increase the sustain of the instrument. As the note dies away, the
compressor will boost the level in an effort to keep the level constant.
Set the controls as follows:
Threshold: Center, XX% (where XX is the
compression point).
Ratio: approximately 4:1
Attack Time: 1 mS to 100 mS
Release Time: > 100 mS
Noise Reduction
Noise reduction will reduce low levels even further in the assumption
that low levels are noise.
Set the controls as follows:
Threshold: Below, approx. 30%
Ratio: approximately 0.7:1
Attack Time: approximately 100 mS
Release Time: approximately 100 mS
