c/24 and 192 io calibration

[raga2000]

hi,the sound come truth c/24 (mic or instrument)i increase the trim until led clip indicator in c/24 began to flashing(it must be distorted or near the 0db),now send to 192io (via +4 db input or -10db input)and record to audio trac in pt,wave is so thin and also 192io meter show around-6or LOWER!!it means that i cant record any sound in around 0db and all the recorded wave are very thin.in this case i miss my 120db dynamic range of 192io.is there any body knwo about it?
