Operation Manual
Turning the Power On and Off
Power Supply
To make the CC121 active, connect the CC121 to
your computer via a USB cable so that the power
can be supplied from the computer to the CC121. To
activate the motorized touch-sensitive fader, you'll
need to also connect the AC power adaptor to the
CC121 and a proper AC outlet. Instructions for these
connections are given here.
IMPORTANT
Connecting the power adaptor to the CC121 and
turning on the power does not supply the CC121 with
necessary power; the power adaptor is merely an
auxiliary power source for the motorized fader.
1
Make sure that the [STANDBY/ON] switch on
the rear panel is in the STANDBY position.
2
Connect the USB TO HOST terminal on the
rear panel to the computer by using a USB
cable.
Now you are ready to turn on the power. When
you want to activate the fader as the touch-sen-
sitive motorized fader, go to step 3.
CAUTION
• While the CC121 is turned ON, a Mac computer
connected to the CC121 via USB cannot enter the
power-saving mode (such as sleep and sus-
pended) even if you do not operate the computer
for a long time. When connected in this condition,
the CC121 continues to draw power from the com-
puter, 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
CC121 to STANDBY in order to save power and
avoid draining the computer’s battery.
NOTE
· The USB bus-power function can be used only when
connecting the CC121 to a computer directly (without
using a hub) or when connecting the CC121 to a
computer via a self-powered USB hub. This function
cannot be used when connecting the CC121 to a
computer via a bus-powered USB hub.
3
Connect the power adaptor’s DC cable to the
[DC IN] jack on the rear panel of the CC121.
4
Securely connect the power adaptor to 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.
• Wrap the DC output cable of the adaptor around
the cable clip (as shown below) to prevent acciden-
tal 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.
NOTE
· You can connect or disconnect the AC power adaptor
to/from the CC121 while the [STANDBY/ON] switch is
set to ON.
