If you’re using K-Mix’s audio interface capabilities to send audio to/from a computer, all audio travelling
over USB will stop while the disconnect occurs. The audio device will briefly disappear from your DAW or
other audio software, which could cause issues; you may have to restart your DAW to get things back in
working order.
It’s possible that there may be other computers that exhibit this issue, but we have only encountered it
when using Mac Minis.

If this issue affects you, there are a couple of potential solutions:
• Try a powered USB hub, preferably a USB 3.0 hub. This generally eliminates the issue completely.
• Try a different USB port on your computer. In our tests we have noticed that the connection drop will
occur on certain USB ports, but moving K-Mix to another port makes the problem disappear. There are
a number of reports of this behavior with other USB devices from other Mac Mini owners.
• If your microphone can get by with +12V phantom power, try using +12V on your K-Mix. The smaller
power requirements for +12V (as opposed to +48V) don’t put as much strain on the Mac Mini’s USB
port while power is ramping up, causing the connection issue to disappear. You can switch your
K-Mix’s phantom power voltage from the mixer itself or the K-Mix Editor .

The Audio MIDI Setup application on Mac OS X allows you to rename MIDI devices, a cool feature that can
help distinguish between multiple copies of the same device.
While it is a cool feature, it is not recommended that you rename your K-Mix if you want to use it in conjunction
with the K-Mix Editor.
Renaming K-Mix in the MIDI Studio section of Audio MIDI Setup will make it impossible for a connection to be
established between K-Mix and the K-Mix Editor. The editor looks for a device named “K-Mix” to establish a
connection; if K-Mix has been renamed, a connection can’t happen.
If, however, you do not plan on using the K-Mix Editor, feel free to name your K-Mix whatever you like!

If your computer is running Mavericks or Yosemite (Mac OS 10.9 or 10.10) it is possible your K-Mix will not be
recognized by the computer and make a proper connection. This is due to a bug in the operating system that
typically appears when using a class-compliant USB audio/MIDI device (like K-Mix). When this bug appears it
can lead to connectivity issues with the K-Mix Editor and other audio software.
Luckily, there is a fix for this issue.
To get your K-Mix recognized by the operating system:
1. Open Audio MIDI Setup (located in the Applications/Utilities folder).
2. View the MIDI devices window by clicking Window in the menu bar at the top of the screen and selecting
Show MIDI Window (this may be named “Show MIDI Studio” depending on the operating system). A
window with all recognized MIDI devices will appear.
3. Click the Configuration drop-down menu and select New Configuration .
