m-track hub very low sound level on akg k702 with macbook pro

Hello. I bought m-audio m-track hub for my akg k702 to use it on my macbook pro but i was disappointed. the sound from the headphones very low. and beside seems power supply doesnt work? if i plug it or unplugged i'm still having the same sound level. if i plug headphone directly to the computer i even get a higher sound. what am i missing? thanks.

  • Hey Yurttaş,

    Thanks for posting!

    Sorry you're having some trouble with that! It looks like the impedance of those AKG headphones are relatively low so the Hub should not have too much trouble driving them. The power adapter will only be necessary to use the Hub as a USB hub - if you are using it as an audio output device, only the USB connection is necessary.

    I would recommend testing with a different set of headphones just to rule that out. If you continue to have some trouble, it sounds like the output of that Hub might be the problem. Warranty and non-warranty claims cannot be handled here on the forum but I can point you in the right direction! Here are a couple of options that you could choose from:

    • Submit a Warranty or Service Inquiry with our Technical Support team by logging onto the M-Audio Support Page. Select Warranty or Service Inquiry from the drop down menu. This will not require a support code.

    or

    • For faster support, call or email your nearest Support Office or International Distributor. Select your country to find the nearest office.

    Make sure to reference or link to this thread to help out the support team.

    I hope this helps! Let me know if you have any additional questions.
