Audio recording with very low input in garage BAND using Scarlett 2i2

Hi there,

I am using garage band with an iPad Pro M4. I Connect a Focusrite Scarlett 2i2 with 2 mics ATR 2100 to record voices. When I plug my 2 mics within Scarlett to Garage band, The wave of sound are almost flat. The sound is recording but no waves. It does not happen when I use only 1 micro connected directly to The iPad.

When I to with The Scarlett my input gain is Frozen in The iPad. Havé ion ever get this?

Thanks for your help
