What is the difference between the soft saturation on the Lavry Gold MK II versus the Lavry Blue "A" Saturation?

Th gold MKII has 2 settings for digital soft sat.
The LavryBlue AD has one setting of digital and one setting for analog sat.

Analog soft sat is done BEFORE the signal gets to the converter. It lowers the the analog peaks when one overdrives an AD with too much analog signal.

Digital soft sat is done AFTER the conversion - so it is done in the digital domain. The idea is to boost the amplitude by say 6dB, making the sound louder. One can, of course, boost a -50dB by 6dB to get -44dB. You can boost a -20dB to be -14dB... But you can not boost say a -3dB by 6dB, because that "goes over" zero dB (zero is the max). Therefore, the digital soft sat reduces the amplitude boost when you have high value peaks, just like an analog tape would.

Hi Dan,

Do the digital soft sat circuits act like tape and compress the signal when driving it? And are there harmonics as a result of over-driving the circuit?

Apologies if this question has been answered before.

The digital soft saturation is algorithmic, and it is an emulation of a tape.
Any time you deviate from a perfect linearity, you "end up with harmonics". That includes analog tape, tubes or any gear and software that "colors" the sounds  

Analog sat, digital sat and the rest of makes you "deviate" from the original sound, going against transparency. The analog sat is a compromise - protection against signal overdrive. The digital sat makes the sound louder, and some people like the sonic impact of the harmonics, depending on the music.
