Inputs 1 and 2 on K-Mix are XLR/TRS combo jacks, allowing for microphones to be connected via XLR
connectors, and Hi-Z instrument / line level devices to be connected via 1/4” TRS connectors.

K-Mix provides full phantom power functionality for inputs 1 and 2.
• Phantom power can be enabled/disabled individually for input channels 1 and 2, directly from the
K-Mix hardware or via the K-Mix Editor .
• Phantom power voltage levels can be set to 48V (default) or +12V.

In addition to line level signals, K-Mix inputs 3–8 are capable of receiving phono level audio signals.
• Inputs 3–8 each have their own line/phono switch that is accessible from the K-Mix Editor . By default
these are set to “Line”.
• In order to properly accept a phono level signal, the line/phono switch must be switched to “Phono”
for each channel you would like to use with a phono level signal.
When plugging a line level signal into inputs 1 and 2, the signal will run through
K-Mix’s µPre™ preamps; it is possible the signal will run a little “hot”. If this is the case
then it is recommended you adjust the trim levels to reduce the amount of signal
coming into K-Mix.
