Bus Compressor
Gain Reduction Meter
A 10-segment LED bargraph meter
indicating the amount of gain reduction.
Due to the scale of the meter, sometimes
you will only want the first few LEDs
flickering to keep compression to
musical levels on the mix bus.
The scale on the gain reduction meter ranges from 2dB to 20dB
of compression.
Compression Ratio
Specified as a ratio of input vs output (in:out), the ratio control
sets how much compression takes place once a signal has
crossed the threshold point set in the sidechain circuitry.
A ratio of 2:1 indicates that when an input signal crosses the
threshold by 2 dB, an increase of only 1 dB would be present at
the output, thus 1 dB of gain reduction would be produced.
Generally, low ratios such as 1.5:1 and 2:1 are
used over the main mix bus, but feel free to
experiment. As the ratio increases, the compressor
acts more like a limiter (10:1 and 20:1) and can be
very useful or powerful on dynamics sources such
as drums or vocals. The soft knee design provides
a gradual entrance to compression from below the
threshold, and is very smooth.
Ratios can be set to:
• 1.2:1 (very gentle)
• 1.5:1
• 2:1
• 4:1
• 10:1
• 20:1
