What do you all think regarding the Omega (relative to the Fisher F5) implementing the threshold into the sensitivity control?
I am confused on something regarding this. In the post below M. Hillis says the gain is from 1 to 70 and above 70 the threshold kicks in. Does the gain still increase after 70 or is it just the threshold that is increasing? (I've seen people post the latter). BTW - My Omega runs very quiet at even 99 sensitivity most of the time so I'm a bit perplexed by the term "threshold" here as I thought threshold was a hum and not just boosting weak audio signals. I imagine testing would need to be done to verify this.
This post taken from Mike Hillis goes into the details: Full F5 vs. Omega Post Interesting post btw. He favors the F5 so it's biased but there is still lots of good info on the Omega 8000. Here is part II F5 vs Omega 8000 part II

Mike Hillis said:The Omega manual states that the Sensitivity control combines the Gain and threshold controls into one rotary dial. There is no independent threshold control on the Omega. The Gain settings are located in the range of 1 through 70 and settings above 70 through 99 activate the threshold settings. The threshold range of the Sensitivity setting increases the audio output making the weaker signals easier louder and easier to hear much like the +1 through +9 Threshold settings on the F5. This has its pluses and minuses. For one thing, the gain setting has a finer adjustment range and the high gain settings are very sensitive. If you can get this high in the field, moving up into the threshold range will give you an increased audio output on the weaker signals. The bad thing is that not only are all signals multiplied by the high gain settings to get here in the first place, they are also made louder by the threshold feature. The stability enjoyed by the F5 combinations are not available on the Omega. It is still as sensitive, just not as adaptable. Stop and think about this. Before I can use the threshold feature of the Sensitivity control I have to max out the Gain setting. There is no flexibility. I only have a on or off arrangement. The added benefits of the threshold are only available if I can max out the gain. Second, I can only increase the threshold settings. I cant decrease them. Additionally, there is no sensitivity control for the all metal auto tune mode on the Omega. In the all metal mode, The sensitivity control now becomes a Threshold control. Raising the sensitivity settings increase the audio volume of the threshold hum, high sensitivity setting = very loud hum.
