INTRODUCTION
AA EN API VES
Thank you for purchasing this Yamaha PF1500 Electronic Piano. This keyboard
instrument incorporates the following features:
Yamaha's AWM (Advanced Wave Memory) tone genera-
tion system, which digitally processes the sounds of actual
instruments, creating authentic timbres. The AWM sys-
tem compresses data so that more data can be stored in the
piano.
Specially developed keyboard provides an action that is
lighter than that of an acoustic piano, yet sensitive and
natural, so the player who is used to a grand piano can
switch easily to a PF1500 piano.
Velocity sensitivity to allow expressive performance with
subtle variations in tone and volume that respond to the
way you play.
e Full 16-note polyphonic capacity
e. A powerful internal 20W+20W amplifier, with a stereo 2-
way speaker system to reproduce the sounds of an acous-
tic piano with full, rich, and deep tones.
MIDI capability to allow control of and control by other
MIDI instruments (refer to the MIDI OPERATION section
of this manual for more information).
The PF1500 is equipped with a digital reverberation unit
with three programs, enabling performances with ambi-
ence and atmosphere. In addition, this effect may be used
to modify the sounds of external devices (rhythm program-
mers, tone generators or synthesizers) amplified through
the piano.

PRECAUTIONS
pa
Your new PF1500 piano is a fine musical instrument and should. be treated as
such. Though it is ruggediv constructed and offers the reliabilitv of solid-state
circuitrv, handle it with care and common sense. Keep the following points in
mind, and vour piano will give vou vears of reliable service.
e Location
Avoid exposure to direct sunlight or other sources of heat.
Vibration, excessive dust, cold, low or high humiditv can
also cause malfunction.
e Relocation
When moving the piano, unplug the AC power supply and
all other connecting cables to prevent damage to cords and
jacks.
e Handling
Avoid rough handling. Don't drop or subject the piano to
shock as this can damage the internal circuitrv. Applving
excessive force to terminals or controls mav lead to malfunc-
tions. Alwavs remove plugs from sockets or other terminals
bv gripping them directiv, not bv pulling the cord.
e. AC Power Connection
The voltage requirements for vour Vamaha electronic piano
have been set specifically for the mains supply voltage used
in vour area. If vou have anv doubts about voltage suitabil-
itv, please consult vour local Vamaha dealer. If vou intend
to use vour piano in an area with a different voltage, be sure
to use an appropriate convertor.
Disconnect the piano from the AC outlet when not using it
for an extended period of time. Electrical storms (lightning)
can give rise to power surges, damaging digital cicuitrv even
if the power is turned off.
e Cleaning
Do not use abrasive cleaners, waxes, solvents or chemical ®a
dust cloths to clean the cabinet or keys of your piano, as—
these may dull the keys or damage the finish. Use a slightly
damp cloth and a neutral cleanser.
© Service and Modification
The piano contains no user-servicable parts. Opening it or
tampering with it in any way can lead to electrical shock as
well as damage and will void the product warranty. Refer all
servicing to qualified YAMAHA personnel.
e Interference through Electromagnetic Fields
Do not use your piano close to television sets, radio receiv-
ers or other equipment generating electromagnetic fields.
This could cause both malfunctions of the piano’s digital
circuitry as well as interference noise in the other appliance.

MIDI THRU, OUT and IN terminals
MIDI (Musical Instrument Digital Interface) allows the
PF1500 to transmit and receive musical commands to and
from other MIDI-equipped devices. The IN terminal should
be used if the PF1500 is to be controlled by a sequencer (eg
TQ5) or another keyboard, and the OUT terminal for when
the PF1500 is to control another device (eg the tone genera-
tors of the TOS). The THRU terminal echoes the data
received at the IN terminal, and is used when “daisy-
chaining” MIDI devices. See the sectionon MIDI OPERA-
TION for full details.

En
SETTING UP
A TE LETT
The PF1500 has a second set of speakers located on the underside of the
keyboard. Before playing, attach the stand, referring to the separate Assembly
Instructions sheet.
When the keyboard has been placed on the stand, continue with
the following procedure for playing.
1. Plug the AC power cord into an AC outlet.
2. Though the PF1500 has its own internal amplifier/speaker
system, you can also play it through an external sound
system via the LINE OUT (I,II) sockets. The piano’s
output is normally mono, but when the reverb is used, a
stereo signal is output. The SPEAKER switch on the back
panel may be used to turn the internal speakers on and off.
3. For headphone listening, connect a pair of headphones to
the PHONES socket. When headphones are inserted, the
internal speakers are automatically turned off.
4. Tocontrol the piano from an external MIDI device, connect
the MIDI OUT of the MIDI device to the MIDI IN of the
piano. To control an external MIDI device from the piano,
connect the MIDI IN of the MIDI device to the MIDI OUT
of the piano. (Refer to the MIDI OPERATION section for
further details.)
5. The LINE IN sockets can be used for connecting a tape
recorder, synthesizer, drum machine, etc, which can be
listened to through the piano's own internal amplifier and
speakers while you play. The OUTPUT connectors of the
external source should be connected to the LINE IN sockets
on the piano. The level should be adjusted at the external
source.
NOTE:
Never feed speaker-level signals to the piano's LINE IN
sockets - it could cause damage to the piano's internal cir-
cuitry.
Set the music stand in position by pushing it about 5cm (2")
away from the keyboard, and then lifting it back. The exact
position may then be adjusted forwards or backwards.

L..-—— REVERB
Move this slider to the right for more
reverb effect, and to the left for less.
There are three reverberation settings which may be selected:
ROOM, STAGE and HALL. ROOM simulates the reverbera-
tions to be found in a normal sized room. STAGE simulates the
reverberation characteristics of a stage, and HALL provides a
larger, more spacious feeling than ROOM. Once the selection of
reverberation type has been made, the corresponding LED will
light up. The amount of reverberation affecting the piano sound
can be adjusted by means of the Depth slider (pushing it right
adds more reverberation, and pushing it to the left decreases the
effect). Note that any external sound sources connected to the
LINE IN sockets on the PF1500 will also be affected by the
reverberation settings.
PEDALS
The two pedals on the stand of the PF1500 may be used to create sustain and soft
(una corda) or key hold (sostenuto) effects as on an acoustic piano.
USE OF THE SUSTAIN PEDAL
Press the sustain pedal (the right-hand pedal) to sustain all notes
played, up to the 16-note polyphonic limit. Further notes played
will cancel the first notes played, in the order in which they were
played.

For Transposer(F*,~F,)
PITCH CONTROL
This feature allows you to make fine adjustments to the pitch of
the entire instrument in about 3-cent steps (1 cent equals 1/100th
of a semitone). This allows you to match the tuning of the piano
to that of accompanying instruments or tapes.
To raise the pitch, simultaneously hold down the two lowest
white keys and press any key between C3 (Middle C) and B3 (the
B above Middle C). Each press of the key raises the pitch by three
cents.
To lower the pitch, execute the same procedure while holding
down the lowest white key and lowest black key. Tuning can be
adjusted up to a maximum of +51 cents. Thus, when used in
combination with the Transposition function, the piano can be
set to any pitch within a one-octave range.

MIDI APPLICATIONS
1. BASIC MIDI SYSTEM
(PIANO plus YS100 SYNTHESIZER)
In this example, the piano is used to play the Yamaha YS100
Digital Synthesizer, allowing you to add rich orchestral or instru-
mental voices or exciting synth-type voices to the sound of your
piano. Connect the MIDI OUT of your piano to the MIDI IN of
your YS100. The YS100 will respond to your playing as sensi-
tively as does the piano, and you can select whether or not the
Y $100 responds to the piano’s foot pedals. A volume pedal may
be used to independently control the YS100’s volume, which
may be listened to through the piano's internal speakers (using
the LINE IN audio connections on the piano).
PF1500
2. EXPANDED SYNTH SYSTEM
(PIANO plus TQS plus RX8)
This svstem, using the TQS tone generator/sequencer, allows
you not only to add other voices and percussion accompaniments
to the piano’s voice, but to record and play back multi-part music
on the TQS Digital Tone Generator/Sequencer, which controls
its own and the piano's voices as well as synchronizing the RX8.
The piano's Omni function should be turned off, to avoid receiv-
ing data on unwanted MIDI channels. The RX8 can be pro-
grammed to add full rhythm and percussion parts to songs, kept
in perfect time by the TQ5’s sequencer section.

3. FULL MIDI SEQUENCER SYSTEM
(PIANO, QXSFD, TX81Z and RX8)
Using this high-potential MIDI system, full professional-quality
musical performances can be created, stored on diskette and
replayed using the QX5FD to control all the other components of
the system. Different parts can be recorded on separate tracks of
the QXSFD, and replayed on different MIDI channels for full
multi-timbral polyphonic performances. In addition, with the
QXSFD, transposition, tempo changes within pieces, and full
editing functions on recorded performances are all possible. The
TX81Z can be played from the piano keyboard to give combina-
tions of up to eight sounds simultaneously with 8-note polyph-
ony, so the resources of a full digital orchestra and/or synth
effects are at your fingertips. To round off the system, the
incredibly versatile and realistic RX8 rhythm programmer is
used to add sparkling drums and percussion to the music.

SPECIAL MESSAGE SECTION
ELECTROMAGNETIC INTERFERENCE (RFi): Your Yamaha
Digital Musical Instrument Product has been type tested and
found to comply with all applicable regulations. However,
if it is installed in the immediate proximity of other electronic
devices, some form of interference may occur. For additional
RFI information see the FCC information section located in
this manual.
IMPORTANT NOTICE: This product has been tested and
approved by independent safety testing laboratories in order
that you may be sure that when it is properly installed and
used in its normal and customary manner, all foreseeable
risks have been eliminated. DO NOT modify this unit or
commission others to do so unless specifically authorized
by Yamaha. Product performance and/or safety standards
may be diminished. Claims filed under the expressed war-
ranty may be denied if the unit is/has been modified. Implied
warranties may also be affected.
SPECIFICATIONS SUBJECT TO CHANGE: The information
contained in this manual is believed to be correct at the time
of printing. Yamaha reserves the right to change or modify
specifications at any time without notice or obligation to
update existing units.
NOTICE: Service charges incurred due to a lack of know-
ledge relating to how a function or effect works (when the
unit is operating as designed), are not covered by the
manufacturer’s warranty. Please study this manual carefully
before requesting service.
STATIC ELECTRICITY CAUTION: Some Yamaha Digital
Musical Instrument products have modules that plug into the
unit to perform various functions. The contents of a plug-in
module can be altered/damaged by static electricity dis-
charges. Static electricity build-ups are more likely to occur
during cold winter months (or in areas with very dry cli-
mates) when the natural humidity is low. To avoid possible
damage to the plug-in module, touch any metal object ( a
metal desk lamp, a door knob, etc.) before handling the
module. If static electricity is a problem in your area, you
may want to have your carpet treated with a substance that
reduces static electricity build-up. See your local carpet
retailer for professional advice that relates to your specific
situation.

FCC INFORMATION
While the following statements are provided to comply
with FCC Regulations in the United States, the cor-
rective measures listed below are applicable world-
wide.
This series of Yamaha professional music equipment
uses frequencies that appear in the radio frequency
range and if installed in the immediate proximity of
some types of audio or video devices (within three
meters), interference may occur. This series of Yamaha
professional music equipment has been type tested
and found to comply with the specifications set for
a class B computing device in accordance with those
specifications tisted in subpart J of part 15 of the FCC
rules. These rules are designed to provide a reasonable
measure of protection against such interference.
However, this does not guarantee that interference
will not occur. If your professional music equipment
should be suspected of causing interference with other
electronic devices, verification can be made by turning
your professional music equipment off and on. If the
interference continues when your equipment is off,
the equipment is not the source of interference. If your
equipment does appear to be the source of the inter-
ference, you should try to correct the situation by using
one or more of the following measures:
Relocate either the equipment or the electronic device
that is being affected by the interference. Utilize power
outlets for the professional music equipment and the
device being affected that are on different branch
(circuit breaker or fuse) circuits, or install AC line
filters.
In the case of radio or TV interference, relocate the
antenna or, if the antenna lead-in is 300 ohm ribbon
lead, change the lead-in to a co-axial type cable.
If these corrective measures do not produce satisfac-
tory results, please contact your authorized Yamaha
professional products dealer for suggestions and/or
corrective measures.
H you cannot locate a franchised Yamaha professional
products dealer in your general area contact the
Electronic Service Department, Yamaha Corporation
of America, 6600 Orangethorpe Ave., Buena Park,
CA 90620, U.S.A.
If for any reason, you should need additional infor-
mation relating to radio or TV interference, you may
find a booklet prepared by the Federal Communi-
cations Commission helpful:
“How to Identify and Resolve Radio — TV Interference
Problems”. This booklet is available from the U.S.
