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.
 
Turning 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.
