Sound Card Calibration unable to reach required level

[MarcusFirby]

Hi all,

I am using the Mackie Onyx Producer 2-2 audio interface, however, when I try to calibrate my sound card with the loopback system, despite having the input level and output level all the way to the maximum, I cannot reach the required -12dbFS "In" level. It is also clipping/distorting at around 75% (of both the input and output), and will only allow me to reach around -60dbFS, with the minimum being -35dbFS.

Is anyone able to help me at all, I've watched countless tutorials, including the ones shown on the REW website and those made by GIK Acoustics, yet I still can't get past the sound card calibration stage.

Any help or suggestions will be greatly appreciated, not too sure why I didn't come to the forum sooner.

Thanks,

Marcus

Make sure the Mix knob is turned all the way to DAW. Soundcard cal uses the input and output that will be used for measuring, so check the loopback connection is on the correct channels. Can you post a screenshot of your REW soundcard preferences?

Hi there, sorry for the late reply.

Here is a screenshot of my preferences page.

My input level and output level are both at the maximum here.

The Windows input volume control shows it is at 25.4%.

It would be pretty odd if your interface couldn't deliver enough output to fully drive the input, looks like the output level on the interface is controlled by the Monitor knob.

John, he's running that interface on a Mac.

Don't you just love it when they want help and don't give you enough information about their _full signal chain_ to have a clue about diagnosing the issues...

Yes, sorry, OS input volume control is at 25.4%.

Yes, sorry, OS input volume control is at 25.4%.

The OS volume is at 100%, how do I turn up the input volume of the operating system?

Edit: I've found it, it was just over 50% so I've turned it up to the max, I will try again with the calibration now.

What other information do you need?

Generally the volume control figure shown in REW matches the volume control you'll find in Audio Midi Setup.

I've managed to get the sound card calibration completed. Thank you everyone.

Sometimes it is just an issue within the computer itself (MacOS input volume) as opposed to what I was doing for the calibration itself.

Thanks!

Lucky you, congratulations! I recently discovered REW and I am impressed!
