Power Supply
Make sure that the MOTIF-RACK’s [STANDBY/ON]
switch is set to the STANDBY (off) position.
1 Connect one end of the AC cable to the PA-300.
2 Connect the PA-300’s DC plug to the MOTIF-
RACK’s DC IN terminal on the instrument’s rear
panel.
3 Connect the other end (normal AC plug) to the
nearest electrical outlet.
Use only the AC power adaptor supplied with the
MOTIF-RACK or an equivalent recommended by
Yamaha. The use of an inappropriate replacement can
pose a fire and shock hazard!
Make sure your MOTIF-RACK is rated for the AC
voltage supplied in the area in which it is to be used (as
listed on the rear panel). Connecting the unit to the
wrong AC supply can cause serious damage to the
internal circuitry and may even pose a shock hazard!
Even when the switch is in the “STANDBY” position,
electricity is still flowing to the instrument at the
minimum level. When not using the MOTIF-RACK for
an extended period of time, be sure to unplug the AC
power adaptor from the wall AC outlet.
Power-on Procedure
Once you’ve made all the necessary connections (page
15) between your MOTIF-RACK and any other
devices, make sure that all volume settings are turned
down all the way to zero, then turn on the every device
in your setup in the order of MIDI masters (senders),
MIDI slaves (receivers), then audio equipment
(mixers, amplifiers, speakers, etc.). This ensures
smooth signal flow from the first device to the last (first
MIDI, then audio).
n When powering down the setup, first turn down the
volume for each audio device, then switch off each
device in the reverse order (audio devices first, then
MIDI).
Turning on the MOTIF-
RACK
Before you switch your MOTIF-RACK on or off, turn
down the volume of any connected audio equipment.
1 Press the [STANDBY/ON] switch.
After a while, the default display appears (as set in
the Utility parameter, Power On Mode display).
n If the LCD is difficult to read, you may need to adjust
the display contrast. To do this, simultaneously hold
down the [UTILITY] button and turn the data dial.
2 Raise the sound system volume to a reasonable
level.
3 Turn the MOTIF-RACK’s [VOLUME] knob
clockwise to set an appropriate volume level.
