This tool calculates RCOMP and RGATE from the compression ratio and noise gate level, respectively. The effect on the SSM-2167 transfer function is graphed below. Conversely, the compression ratio and noise gate levels can be determined for a given RCOMP and RGATE.
- Select the series of part you are using (SSM2167-1 or -2).
- Select either the Compression Resistor (between 0-175), or the Compression
Ratio (From 1 to 10).
- Select either the Gate Resistor (between 0-5000), or the Noise Gate
Level (-40 to -55).
The transfer characteristic for the selected resistors is shown in red, with a 1:1 linear characteristic shown for reference in green. The chart is log-log.
