MIX COMPRESSOR/PEAK LIMITER
DYNAMICS ‘In’ Switch – Puts
both compressor and limiter in circuit.
When the dynamics are out, they are hard
bypassed, clearing the signal path of any
unnecessary components.
Threshold – Sets the point at which
compression begins to work. Due to the
soft-knee characteristic of the compressor,
some slight gain reduction is applied
before the threshold level. This gives the
compressor a gentler, more musical
response.
Ratio – Varies the amount of
compression. The numbers on the dial
show the number of decibels that must be
put in above the threshold to get one
more dB out. The greater the number, the
harder the compression. The diagram
below shows how the compressor affects
the input/output ratio at different ratio
settings. The off position allows you to
bypass the compressor whilst leaving the
limiter in place. Dead handy if, heaven
forbid, you’re inserting a compressor of
your own.
Use high ratios with high
thresholds to control rogue
peaks, or low ratios with
low thresholds to apply a more
gentle overall compression.
Attack – The time for which the input
signal must rise above the threshold level
before the compressor takes effect.
