Connections
Connections must be made with the power turned
off. Please be aware that careless operation may
damage your speaker system or cause malfunctions.
1. Connecting the power cable
1. Turn off the power of the OASYS.
2. First connect the included power cable to the
OASYS’ rear panel AC power inlet.
If your power cable uses a separate ground wire,
you must connect this ground wire before inserting
the plug into the AC outlet. When disconnecting,
you must first disconnect the plug before you
disconnect the ground wire. If you are unsure of
how to make connections, please contact Korg
customer service.
Make sure that your AC outlet is the correct voltage
for your instrument.
2. Analog audio output connections
Here’s how to connect the OASYS to your analog amp
or mixer.
If you’ve connected a stereo audio amp, be aware
that playing at high volume may damage your
speaker system. Be careful not to raise the volume
excessively.

If a passive type guitar (a guitar
without an internal preamp) is
connected, it will not be possible
to sample at an appropriate
level due to the impedance
mismatch. Such instruments must
be connected via a preamp or
effect unit.
If you are using a condenser
mic that requires phantom
power, turn the PHANTOM
POWER switch ON.
WARNING: Never connect an
unbalanced instrument,
device, or mic to the XLR jack
if phantom power is turned
on.
