I am trying to calibrate my soundcard to use with REW. I have the fast track ultra. I am not sure how to properly plug everything in the do the calibration. I plugged my speakers in the output 1 and 2 in the back of the audio interface and I have a 1/4 inch cable running from output 3 in the back to microphone input 1 in the front. Is this the correct set up? Should I have phantom power on or off? Thank you for helping me I cant find much on the fast track ultra and I want to make sure I am doing this right.

Also when I plugged it in this way and tried to calibrate the out was at -12 dB. I tried to match up the meter labeled left by turning the main output knob up. the CH 1 knob was turned all the way up and I didn't mess with any settings on the mixer section in the software that came with the audio interface. Every time I would turn the Main output up I would get close but could not get to the -12db output setting. I figured they were supposed to match up. Along with that the sound level was unbearably loud and would cause my speakers to distort. I cant for the life of me figure out what I am doing wrong or right lol. Thank you

Welcome to the Forum, adjamant!

For calibrating the sound card you aren’t supposed to have it hooked up to your playback system. Just run a cable from the sound card’s output to its input for the calibration. You don’t need phantom power, but it’s only available for XLR inputs anyway, not the 1/4” connections you’re using. If all fails and you can’t obtain a calibration, it’s probably no big deal. Decent quality sound cards these days typically have virtually ruler-flat response out of the box, even ones way cheaper than yours.

Regards,
Wayne

Thank you for answering Wayne I appreciate you taking the time to help me. If I avoid the soundcard calibration is there something different I should do. I am trying to test my room using the ECM8000. Also what levels should by audio interface me at to make for proper measurements or does that not matter much?

Here I have attached my rew file of the calibration. I am not sure what this information means exactly but from the first graph I am assuming things went ok. If you don't mind letting me know what you think I would appreciate it. Thank you.
