Eliminating the Loop
As a first step, always connect your devices to the same power outlet (e.g., with a multi-
outlet power strip). Assuming that you have connected your audio interface, the next trouble-
shooting step is to disconnect all devices that you are not currently using, but not the ampli-
fier and/or speakers. This also applies to other peripheral devices you may have connected to
your computer (external data storage, CD recorders and especially radio or television cables).
In case the ground loop disappeared, you can add the devices one after another to identify
which device is responsible.
• You can test whether the amplifier or powered monitors create the ground loop. Moni-
tor your audio signal from the headphones output of the KOMPLETE AUDIO 6. The
amplifier / powered monitors need to be physically disconnected from the KOMPLETE
AUDIO 6 for that. In case the ground loop is not audible on the headphones, you need
to lift the ground on your amplifier or the powered speakers. Contact the manufacturer
of your amplifier/speakers before lifting the ground to find out if ground lifting is sup-
ported on your device.
• On laptops, low quality power supplies often lead to ground loop noise. Run your
laptop on its battery to see if the ground loop disappears. In case the ground loop dis-
appears, you need to lift the ground on your laptop. Contact the manufacturer of your
laptop before lifting the ground to find out if ground lifting is supported on your device.
• On desktop computers, the computer monitor (screen) might cause the ground loop.
Turn your monitor off and disconnect its power supply while you hear the ground
loop. In case the ground loop disappears, you need to lift the ground on your monitor.
Contact the manufacturer of your monitor before lifting the ground to find out if ground
lifting is supported on your device.

Physically Re-configuring the KOMPLETE AUDIO 6
Connect the KOMPLETE AUDIO 6 to another USB port on your computer. Try all USB ports
on your computer until you find the one that works best.
8.6
Check your IRQs (Windows only)
IRQ stands for Interrupt Request. This is the way in which Windows allocates resources to
the various devices and ports in your system. If your KOMPLETE AUDIO 6 is on a port that
shares an IRQ with other devices, you may have an IRQ conflict. Please refer to the Knowl-
edge Base on the Native Instruments website and contact support.
