Output Limiter
This bit disables the output limiter function when set to 1. Can only be disabled when

the AGC compression ratio is 1:1
NoiseGate Threshold
These bits set the threshold level of the noise gate. NoiseGate Threshold is only
functional when the compression ratio is not 1:1
Output Limiter Level
These bits select the output limiter level. Output Power numbers are for 8
