Noisy Phantom Power Alesis I/O Dock II

I have owned this interface for about two months. The phantom power switch when switched "on" to use with a condenser mic is very noisy, crackling sounds, and hiss. I have isolated the inputs and used an out board pre amp to see if the circuitry is ok and "it is" for inputs 1 and 2, The IO Dock 2 pre amps are medium grade to begin with and need to be opened up near or past the 9 oclock position for my dynamic mics sm 57 and EV RE 27. Has anyone else experienced the noise issue with the phantom power for the IO Dock II? It just may be that its pooched and needs to be repaired? Not sure

  • Hello,

    Thanks for posting. 

    Are you using the correct power supply for your IO Dock II? If you're located in the US, you should be using a 12V 2.0 A power supply. The part number is  AL7-10-1215.

    If you're still having problems, you may need to replace the power supply, or service your IO Dock II. For assistance with this, please get in touch with your nearest Support Office. You can find their contact information on that page.

    Hope this helps!

    I have been waiting for an RNA by retailer for over a week for warranty Phantom pwr. should no give any amount of hiss at all
    its directly recorded when doing voice over or vocals and is unacceptable

    I also contacted Alesis just a few moments ago and am expecting a call back.

    all other functions are operating as they should although the pre amps are basic in form and function

  • .... i have noted that the closest support office is in the US however my retailer told me that it is Quebec Canada? i am glad the unit is still somewhat usable as i am beginning to think this could be a long drawn out affair, trying to get an answer,solution or warranty repair. The PA Shop in London ON Canada where i bought the io dock assured me that Alesis is quite responsive and act quickly in getting things done! I hope that is true
    The power supply is a 12v 2.0A Sunny switchable adapter i guess tha
    ts the Canadian version? al other functions on the io dock work fine but as mentioned the pre amps are lacking but that's exceptable for a unit under $300 bucks Canadian
