I just test your words - NOT like you said !
I have +15 pre-amp , so you said to set gating to -15db and turn OFF that option ! Well, red bar for the Gate is NOT act like my settings !
So i again will say : NOT right !
If your words were right, then if i set gating (without the option) to +15db , AGC must act like it`s now , but again is NOT.
If it must be like it`s now at my place - gating must be up to +40 , so i can set it 20+ db to compensate only the pre-amp. But gating is only to +21.
Then what will be if i set preamp to +30 or 40 ? From where to get this gating level then ?
I think you misunderstood me.
When your preamp is +15, gating Level at "x" in your preset with this option ON (based on Level before preamp), you will get the same gating behavior when you Switch this option to OFF and increase your gating Level by 15dB, to "x + 15".
When the gating circuit measures AFTER preamp, the measured Level is higher (in your case 15dB) than when it measures before. And cause the Level difference is static (determined by the preamp slider) you can compensate it by the gate threshold.
Other description:
A sports commentator (right word?
) with ambience from the Stadion:
Levels before preamp:
Commentator: -15dB
Ambience: -25dB
Levels after preamp, set to +10:
Commentator: -5dB
Ambience: -15dB
You want to use the gate to prevent ambient noise raising by the AGC in speech pauses.
When you set gate threshold to -20, it will close on speech pauses when this switch is on, but not when it's off.
But it will also close when switched off when you set it to -10.
That's why you don't Need this Switch.
