Installation
4 Korg 1212 I/O
English
IMPORTANT: Within each group (input or output), all of the jumpers
must be set the same way: either all installed, or all removed.
When the jumpers are installed, the level is set to -10 dBV; when they are
removed, the level is set to +4 dBu. The 1212 I/O ships from the factory
with all six jumpers installed, so that both input and output are set to -10.
