Vox Jam Installationshandbuch Seite 9

If you're using the JamVOX Monitor with other software that supports CoreAudio or ASIO,
connect the output jacks of your synthesizer, other electronic instrument, or audio source to
these jacks.
NOTE The JamVOX Monitor gives priority to the front panel input jacks. These rear panel
input jacks cannot be used if a guitar or mic is connected to the front panel input
jacks. If you want to use these jacks, disconnect your guitar and mic from the front
panel input jacks.
