Hey all,
Picked up and Audient ID4MKII to do some FR measurements for a Nelson Pass diy (active biamp) xo and full range EQ project and a pair of Altec Model 14s.
I've got a driverack PA2 and used that to determine my needed simplistic filters and have determined & built the needed circuits for the EQ and xo. I then went to an xkitz solution, which convinced me getting DSP out of the picture (& I can't affort Accuphase df-55 or xilica, lol) is a must, but needed an external parametric EQ, which I want to get out of the signal chain, just because I want to reduce the hardware footprint for adding a large nakamichi deck to the rack.
However, now I need to take measurements to first adjust the xo high and low SPL levels and then tweak the EQ circuits. (3 simple filters - baffle step correction, flattening a midrange peak and a high lift)
Soo with that long winded intro... my question is on getting the audio interface dialed in/calibrated, specifically the loopback test.
Any reason I can't use a TS male to male cable from one of the audio interfaces speaker out (line level) into the microphone in?
Reason I'm asking is that in a previous question on another site, someone had recommended using the instrument input, instead of the mic input, which I don't understand the logic behind, because it's a FET input designed to color the sound, which seems counterproductive and opposed to the intent of the calibration process.
I tried to do this in the digital domain using the audient's digital loopback feature, but this doesn't seem to work as the gain from input is too low for some reason to match up to the output, perhaps because it's digital and the way REW works or maybe config issues, but I don't know.

Link to the thread that has me a bit confused.

REW + USB interface loopback question
Hi All, I am trying to setup my USB interface to allow loopback as time reference with REW. I have Audient iD4 mk1 and I wonder if it is possible to set it up with analogue cable connecting some inputs and outputs to achieve analogue loopback to be used as time reference for REW and measuring...
