Power Supply
Setting Up
Since the WX5 is a MIDI controller, it must be used with a MIDI tone generator to produce sound. Yamaha recommends the
VL70-m or an MU-series XG tone generator, but just about any MIDI tone generator can be used.
WX-Compatible Tone Generators
When the WX5 is connected to a WX-compatible tone generator such as the VL70-m via the supplied WX cable (the tone
generator must have a WX IN connector) power is supplied to the WX5 via the WX cable and no other power supply is required.
This means that you don’t have an extra cable connected to the instrument, or the extra weight of batteries inside the instru-
ment.
Standard MIDI Tone Generators
When using the WX5 with a standard MIDI tone generator or synthesizer, connection must be made via an optional MIDI cable
(see your music instrument dealer). In this case power must be supplied to the WX5 either from an optional Yamaha PA-3B AC
Adaptor, or a set of six SUM-4 batteries installed in the instrument. See “Power Supply”, below.
The power supply connection or battery installation described in this section is only necessary if you will be
connecting the WX5 to a standard MIDI tone generator via a MIDI cable.
AC Adaptor
Use only a Yamaha PA-3B AC Adaptor to power the
WX5 from a household AC outlet.
1
Connect the DC output cable from the PA-3B to the
DC IN 12V connector on the WX5.
2
Plug the PA-3B into a convenient AC wall outlet.
Batteries
1
Use a coin to unlock the battery cover, then remove
the cover as shown in the illustration.
3
Clip the AC adaptor’s output cable into the cable holder
on the WX5 before clipping a MIDI cable in to the
cable holder.
• Use only a Yamaha PA-3B AC Adaptor to power the
WX5 from a household AC outlet. The use of other AC
adaptors will void the warranty, and possibly damage
the WX5.

Install a complete set of six new SUM-4 batteries, be-
ing sure to orient the polarity of the batteries properly
as in the illustration.
3
Replace and lock the battery cover.
• When the batteries are almost depleted the LED indi-
cators will flash and the sound may become distorted
or reduced in volume. Be sure to replace the batteries
early to minimize sound quality degradation.
• When an AC adaptor is plugged into the WX5 the in-
ternal batteries are automatically disconnected.
• Always replace all six batteries with new ones at the
same time. Never mix new batteries with old ones, and
don’t mix different types of batteries (i.e. standard and
alkaline), or different brands of batteries.
