Check the listing for details. IK Multimedia AXE I/O USB Audio Interface - Black. Condition: Used. Listed at 150.00 USD. Used IK Multimedia AXE I/O Audio USB Interface for sale. Has been used in a smoke-free home studio. Was purchased from a previous owner - he did not remove the device from his IK Multimedia account, so the control software cannot be downloaded and used. However, the control software is not necessary to utilize the device - controls can be done with the hardware itself and I never had any problems not having the control software. I loved this device - one of the best interfaces I've owned, but I am downsizing my home studio. All functions worked properly when last used. Thank you for checking it out!
