Power Supply
The KX can be powered from one of the following
two sources.
• 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 connector 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. Doing so will also
immediately void the product warranty, even if the
effective warranty period has not expired.
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.
Using the KX as a USB bus-powered
device
The KX is a 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.
Tur ning the Power On and
Off
1.
Turn the power ON by pressing the
[STANDBY/ON] switch to set it to the ON
position.
2.
Turn the power off by pressing the
[STANDBY/ON] switch again to set it 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.

NOTE
· While the KX is turned ON, the Macintosh
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. When connected in this
condition, the KX continues to draw power
from the computer, even if you are not
using it. Particularly when the computer is
under battery power, you should make
sure to set the STANDBY/ON switch of
the KX to STANDBY in order to save
power and avoid draining the computer’s
battery.
· 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.
