Does AHFX attenuate input signal before it hits effects?

I felt that the AHFX attenuate the input signal of 12db before it hits the effects chain ( even if the unit is set o inactive and whatever the input sensitivity is ) the signal heard at he output seems to be attenuated, as it is not written in the manual, can anyone confirm that there is an attenuation of the input signal, if it dose exist it makes sense because we go into a saturation circuit so it is better to attenuate the signal to have a room for distortion.

there is a menu setting for input sensitivity. you can set it to one of i think 4 options.

yes I already mention that whatever the input sensitivity is : input sensitivity will define if the signal is a line level phono level or eurorack level for example ( low will be for phono, high will be foe eurorack ) but I’m talking about other think is there a systematic attenuation after input sensitivity ?

…don’t have the a+fx in use…

but what u got, is a truu analog circuit AND digital fx circuits…i never really understood this kind of combo…also in the a4…truu analog meets digital send fx…at which point in the overall signal chain happens this adding of any digital makeup fx exactly…?..good question…
what’s the exact converting chain here and where happens the split/add before the physical output…?

FYI one can use AH+ without any digital FX to keep a true analog path, there’s an option for this.

I believe input signal is apparently lowered to offer some headroom / avoid clipping.
As there is a reamp option at the end of the unit, one should be able to compensate any volume loss, even when activating no FX module.

There has to be some AD/DA conversion in the FX chain obviously, and even an audible buffer for the Tape FX.

…thanx for clarification…but that much is already obvious knowledge to me…

i’m not really on the questioning side here, since my heat experience is all without the latest fx+ option anyways…but essence remains, since a4, syntakt and heat fx all work in this analog/digital hybrid scenario…what really happens with this analog path vs/mingle the digital path…
not that much the gainstaging part and distortion headroon but the basic logic/chain of command of converting signal flow and summing it all up again…hmmmm…
really can’t wrap my head around it…

On A4, FX are sent FX so mixed with the analog signal that is left untouched.

I would believe it’s the same for Syntakt, or at least that’s how I understand the slightly more complicated signal flow:

On Analog Heat+FX, the analog “Heat block” is surrounded by 2 digital FX blocks, thus by a DA and AD converters.
