Turning the Power On and Off
Power Supply
The KX can be powered from one of the following
two power supplies.
• Power supply from the AC power adaptor
• Power supply from the connected host computer
(USB bus-power)
Connecting the AC Power Adaptor
1.
Make sure that the STANDBY/ON switch of
the KX is in the STANDBY position.
2.
Connect the plug of the power adaptor to
the DC IN terminal on the rear panel.
3.
Plug the power adaptor into a standard
household power outlet.
WARNING
• Use only the included power adaptor (PA-3C or PA-
130) or an equivalent recommended by Yamaha).
Use of a different adaptor may result in equipment
damage, overheating, or fire. In such cases, the
product warranty will be void immediately even within
the effective warranty period.
CAUTION
• Wrap the DC output cable of the adaptor around the
cable clip (as shown below) to prevent accidental
unplugging of the cable during operation. Avoid
tightening the cord more than necessary or pulling on
the cord strongly while it is wrapped around the cable
clip to prevent wear on the cord or possible breakage
of the clip.

Turning the Power On and Off
Using the KX as a USB bus-powered
device
The KX is the bus-powered type device which can
be powered by the host computer connected via a
USB cable. In this case, the AC power adaptor is
not necessary.
1.
Make sure that the STANDBY/ON switch of
the KX is in the STANDBY position.
2.
Connect a computer to the USB TO HOST
connector of the KX by using a USB cable.
3.
Start the computer.
NOTE
· While the KX is turned ON, the computer
connected to the KX via USB cannot enter
the power-saving mode (such as sleep
and suspended) even if you do not
operate the computer for a long time. This
situation vampires the power of the
computer although you do not use the
computer. Especially when the computer
is powered by the battery (not the power
adaptor), make sure that the STANDBY/
ON switch of the KX is in the STANDBY
position to save the power consumption.
· The USB bus-power function can be used
only when connecting the KX to a
computer directly without using a hub or
connecting the KX to a computer via a
self-powered USB hub. This function
cannot be used when connecting the KX
to a computer via a bus-powered USB
hub.
· The USB bus-power function will not work
when using the AC adaptor.
Turning the Power On and Off
1.
Turn the power ON by pressing the
[STANDBY/ON] switch so that this switch is
in the ON position.
2.
Turn the power off by pressing the
[STANDBY/ON] switch again so that this
switch is returned to the STANDBY position.
CAUTION
• Note that a small amount of current continues to flow
while the switch is in the STANDBY position. If you
do not plan to use the KX again for a long while, be
sure to unplug the adaptor from the wall outlet and
unplug the USB cable from the KX.
