BEFORE YOU BEGIN

Power Supply

Your PSR-300M will run either from a supplied power adap
tor or optional batteries. Follow the instructions below accord
ing to the power source you intend to use.

Using the supplied AC Power Adaptor

Plug the DC output cable firom the supplied Yamaha PA-3
AC Power Adaptor into the DC IN jack on the rear panel of the
PSR-3CX)M, then plug the AC Power Adaptor into a convenient
wall AC power socket.

The internal batteries are automatically disconnected when an
AC Power Adaptor is used. Disconnect the AC Power Adaptor
when not using your PSR-300M.

Jse the supplied Yamaha PA-3 AC Power Adaptor (also PA-4 or PA-

40 can be used) to power your instrument from the AC mains. Other
adaptors may cause serious damage to your PSR-300M.

Using BatteriOS (sold separately)

Six 1.5V D size (SUM-1 or R-20) or equivalent batteries
must first be installed in the battery compartment.

• Before replacing the batteries, make sure that the power is turned off.

During battery replacement the memory will be backed up for approxi
mately 1 minute.

1. Open the battery compartment cover located on the instru

ment’s bottom panel.

2.

Insert the six batteries, being careful to follow the polarity
markings on the cabinet.

3.

Replace the compartment cover, making sure that it locks
firmly in place.

Setting Up the Music Stand

Insert the bottom edge of the music stand into the slot

located at the rear of the PSR-300M control panel.

Maintenance

• Location

Avoid exposure to direct sunlight or other sources of heat.
Never leave it inside a car where it can get very hot. It may
cause discoloration or deformation. Vibration, excessive
dust, cold, low or high humidity can also cause malfunction.

• Handling

Avoid rough handling. Don’t drop or jolt the PSR-3(XJM as
this can damage the internal circuitry. Pressing too hard on
keys or controls may lead to malfunctions. When cords are
plugged into the rear panel jacks, pay particular attention not
to apply excessive force to them since this may damage the
terminals.

• Cleaning

Clean the exterior with a soft, dry cloth. Using chemical
solvents will damage the finish.

Caution:

1. When the batteries run down, replace them with a complete

set of six new batteries. NEVER mix old and new batteries.

2. Do not use different kinds of batteries at the same time.

3. In case electrolyte has leaked into the battery compartment,

wipe it off completely before installing new batteries.

4. To prevent possible damage due to battery leakage, remove
the batteries from the instrument if it is not to be used for an

extended period of time.

Auto Power OFF

To prevent unnecessary battery drainage, the PSR-300M
features an Auto Power OFF function that automatically turns
the power OFF if the instrument is not used for approximately

10 minutes.

The Auto Power OFF function docs not operate when the
PSR-300M is powered from the supplied AC Power Adaptor, as
described above.

• Interference Through Electromagnetic Fields

Do not use your PSR-3(X)M close to television sets or other
equipment receiving electromagnetic signals as this could
cause interference noise in the other appliance.

• Service and Modifications

Your PSR-300M contains no user serviceable parts. Open
ing it or tampering with it in any way can lead to electrical
shock as well as damage. Refer all servicing to qualified
YAMAHA personnel.

YAMAHA is NOT responsible for damage caused by improper use.

® DC IN Jack

The DC output cord from the supplied Yamaha PA-3
AC Power Adaptor should be plugged in here when the
PSR-300M is to be powered from the AC mains supply
(refer to “Power Supply” on page 1 for more details).

® HEADPHONES/AUX, OUT Jack

A standard pair of stereo headphones can be plugged in
here for private practice or late-night playing. The internal
speaker system is automatically shut off when a pair of
headphones is plugged into the HEADPHONES jack. The
HEADPHONES/AUX. OUT jack can also be used to de
liver the output of the PSR-300M to a keyboard amplifier,
stereo sound system, mixing console or tape recorder.

MIDI IN and OUT Connectors

The MIDI IN connector receives MIDI data from an

external MIDI device which can be used to control the
PSR-300M. The MIDI OUT connector transmits MIDI
data generated by the PSR-300M (e.g. note and velocity
data produced by playing the keyboard).

More details on MIDI are given in “MOVING UP TO

MIDI” on page 14.

• Note that the PSR-300M‘s keyboard is “touch response" — tfiat
is, you can control the loudness of the sound to a certain
degree according to how hard you play the keys. The degree of
touch sensitivity is different for each voice.

• The PSR-300M features a maximum polyphony of 28-notes
(depending in some cases on the selected voice), so up to 28
notes can be played simultaneously, including extra notes
played when the automatic accompaniment, split, or dual voice
features of this instrument are used. “Full” will appear on the

AUTO HARMONY

THE CHORD MEMORY

This sophisticated feature automatically adds appropriate
harmony notes to a melody you play on the keyboard. You can
choose from 5 different types of harmony.

• Only a single note can be played at a time on the keyboard (or the

right-hand section of the keyboard when in the SPLIT mode) when
the AUTO HARMONY feature is used.

1. Use the [AUTO HARMONY] buttons to select a harmony
type between *‘01” and “05.”

The first time the AUTO HARMONY [A] or [T] but

ton is pressed the current harmony type number will
appear on the MULTI DISPLAY. While the current har
mony type is still showing on the display, press the AUTO
HARMONY [A] button briefly to increment (increase by
one) the harmony type number, or the [T] button to dec­rement (decrease by one) the harmony type number. Hold
ing either button causes continuous incrementing or
decrementing. The selected harmony type number will be
shown on the MULTI DISPLAY while the [AUTO HAR
MONY] [A] or [T] button is pressed (the letter “H” will
appear before the harmony type number).

2. Play.

• In the SINGLE FINGER or FINGERED mode, the left-hand

chords determine the harmony notes that will be applied to the
right-hand melody.

• In the NORMAL mode, all harmony is based on a C major

chord.

• If AUTO HARMONY is used at the same time as the SPLIT

feature (see page 6), harmony will be not be applied to the left­hand voice. Left-hand chord fingerings are used to determine
the harmony applied to the right-hand voice. Usable fingerings
are the same as for the FINGERED mode,

• If AUTO HARMONY is used at the same time as the DUAL

feature (see page 5), harmony will be not be applied to the

second “dual" voice.

• if the synchro start mode is turned off by pressing the

[SYNCHRO START/ENDING] button prior to playing, right-hand
melody and harmony without accompaniment can be produced

— but the left-hand chords will still have to be fingered to pro
duce the appropriate harmony.

The PSR-300M CHORD MEMORY allows you to “record”

and play back chord sequences created using the Auto Accom
paniment feature. You can record a complete accompaniment
part, for example, and then play along with it using both hands
— you’re free to use the entire keyboard for your performance

rather than being limited to only the upper keyboard area.

The CHORD MEMORY also has three separate “banks”
that can be used to record different accompaniments. The
banks can be “chained” — i.e. they will play back in any
specified order. This allows you to record a verse and chorus
in different banks, for example, then “chain” them in the de
sired order for playback.

• Chord sequences containing a maximum of 60 different chords can

be recorded in each bank.

• Material recorded using the CHORD MEMORY is retained in

memory even when the POWER switch is turned OFF (if batteries
are present).

1. Pick out an accompaniment style that is appropriate for

the type of music you want to record.

2. Press the [BANK 1], [BANK 2], or [BANK 3] button

while holding the CHORD MEMORY [REC] button. This
engages the “record ready” mode for the selected bank.
The bank indicator will flash, the metronome will sound,
and the three dots along the bottom of the MULTI DIS
PLAY will flash at the currently selected tempo. Press the

[REC] button again if you want to disengage the record

ready mode and perform some other function.

If the NORMAL or SPLIT mode is selected, the FIN

MOVING UP TO MIDI

MIDI, the Musical Instrument Digital Interface, is a world­standard communication interface that allows MIDI-compat
ible musical instruments and equipment to share musical infor
mation and control one another. This makes it possible to cre

ate “systems” of MIDI instruments and equipment that offer

far greater versatility and control than is available with iso
lated instruments.

The PSR-300M MIDI Connectors

The PSR-300M MIDI IN connector receives MIDI data
from an external MIDI device which can be used to control the

PSR-300M. The MIDI OUT connector transmits MIDI data

generated by the PSR-300M (e.g. note and velocity data pro
duced by playing the keyboard).

Simple MIDI Control

Most MIDI keyboards (including the PSR-300M, of course)
transmit note and velocity (touch response) information via the
MIDI OUT connector whenever a note is played on the key
board. If the MIDI OUT connector is connected to the MIDI
IN connector of a second keyboard (synthesizer, etc.) or a tone
generator (essentially a synthesizer with no keyboard), the
second keyboard or tone generator will respond precisely to
notes played on the original transmitting keyboard. The result
is that you can effectively play two instruments at once, pro
viding thick multi-instrument sounds. The PSR-300M also
transmits “program change” data when one of its voices is
selected. Depending on how the receiving device is set up, the
corresponding voice will be automatically selected on the
receiving keyboard or tone generator whenever a voice is se
lected on thePSR-300M.

The PSR-300M is capable of receiving the same MIDI data,
so a second MIDI keyboard connected to the PSR-300M MIDI
IN connector can be used to remotely play the PSR-300M and
select voices as required.

14

MIDI Sequence Recording

The same type of musical information transfer described
above is used for MIDI sequence recording, A MIDI sequence
recorder can be used to *Tecord” MIDI data received from a
PSR-300M, for example. When the recorded data is played
back, the PSR-300M automatically “plays” the recorded per
formance in precise detail.

Functions

The Remote Control Mode

The Remote Control mode should be used when the PSR-

300M is to be connected to a second keyboard which it is to
control. If the PSR-300M is being used as the receiving de
vice, it can be played from an external keyboard while the
panel controls — including auto accompaniment — operate
normally.

• If the TEMPO [A] or [T] button is pressed during external sync
mode is engaged, "EC" (External Clock) will appear on the
display.

• External synchronization Is automatically selected when MIDI
clock is received. If the external MIDI clock data is not received,
internal clock operation is automatically resumed.

• Velocity sensitivity is dependent on the selected voice.

• Refer to the Remote Control Mode “MIDI
Implementation Chart” on page 34 for more details.

Remote Control Mode Transmission

The following points apply to MIDI data transmitted by

the PSR-300M in the Remote Control mode.

• Transmitted note numbers are not affected by the Transpose
setting.

• In the NORMAL or SPLIT mode, all keyboard data is transmitted
via the specified MIDI transmit channel. When the FINGERED or
SINGLE FINGER mode is used, only MIDI data corresponding to
notes played on the right-hand section of the keyboard is
transmitted via the MIDI OUT connector on the specified MID!
transmit channel.

Remote Control Mode Reception

The following points apply to MIDI data received by the

PSR-300M in the Remote Conlrol mode.

• MIDI start messages control PSR-300M rhythm, chord memory

record start, and chain play start in the same way as the panel
[START/STOPl button.

• MIDI stop messages have the same effect as pressing the panel

[START/STOPl button when a function is running.

• OMNI ON means that reception can occur simultaneously on all

available channels (1 through 16). When a single receive channel
is selected, reception only occurs on the specified channel.

• In addition to note and velocity data, the PSR-300M responds to

program change, sustain ON/OFF, start, stop, and MIDI clock
messages.

• Transpose settings affect received MIDI note numbers.

• A MIDI START message is transmitted whenever the rhythm or
accompaniment Is started, and a MIDI STOP message is
transmitted whenever the rhythm or accompaniment is stopped.
The same applies to demo and chord memory start/stop
operations.

• Accompaniment style, demo, chord memory, and transpose data
is not transmitted.

*Refer to the Remote Control Mode “MIDI

Implementation Chart” on page 34 for more details.

The Multi Mode

The Multi mode should be used when the PSR-300M is to

be used as a tone generator, for example, receiving data from a

second MIDI device (such as a sequencer). In this mode the
PSR-300M can receive on multiple MIDI channels, each chan
nel corresponding to a different voice. The PSR-300M panel
controls will not function when the Multi mode is selected.

Multi Mode Selection

If the Remote Control mode is currently selected, the
Multi mode can be re-selected by pressing the numeric
VOICE/STYLE [0] button while holding the CHORD
MEMORY [REC] button. “I J” will appear on the display.

___

Multi Mode Reception

In the Multi mode the PSR-300M functions as a multi­timbre tone generator, allowing different voices to played
on all 16 MIDI channels (channel 16 is reserved for rhythm
only). Since the PSR-300M employs the Yamaha Dynamic
Voice Allocation system, it is not necessary to specify the
number of notes that can be played via each channel. A
maximum of 28 notes can be played simultaneously via all

channels.

• MIDI note and velocity messages received on a MIDI channel will

affect only the voice selected for that channel.

• Velocity sensitivity for each voice is set to a dynamic range of 48

dB linear.

• SUSTAIN ON/OFF messages are ignored.

• A program change number will select the voice controlled via the
channel on which it is received. The new voice number is shown
on the display for approximately 2 seconds. The program change

number is the same as the voice number (00 — 99).

• Program change messages on channel 16 are ignored.

• MIDI start, stop, and clock data will be ignored.

• Refer to the Multi Mode “MIDI Implementation Chart” on
page 35 for more details.

Multi Mode Transmission

The default transmit channel in the Multi mode is the
same as that in the Remote Control mode, and can be set
via the same procedure (see below). The transmitted data is
also the same as in the Remote Control mode, except that
no MIDI start/stop message transmission occurs.

• Keyboard note ON/OFF data is transmitted via the specified MIDI

transmit channel, but the internal tone generator does not sound
(LOCAL OFF).

• The transmitted note numbers are not affected by the instrument’s

TRANSPOSE setting.

• When a new voice is selected, the corresponding MIDI program

change message is transmitted on the specified MIDI transmit
channel. The internal voice assigned to that transmit channel will
also change accordingly. The program change number is the
same as the voice number.

• The channel-16 program change number will not be transmitted.

TROUBLESHOOTING

Something not working as it should? In many cases what
appears to be a malfunction can be traced to a simple error that
can be remedied immediately. Before assuming that your
PSR-300M is faulty, please check the following points.

1. PROBLEM

■ The PSR-300M speakers produce a “pop” sound when
ever the power is turned ON or OFF.

CHECK

• This is normal and is no cause for alarm.

2. PROBLEM

• No sound.

CHECK

• Are the MASTER VOLUME control and accompani
ment volume levels turned up high enough?

3. PROBLEM

• Rhythm won’t start or no rhythm sound.

CHECK

• Is the accompaniment volume turned up high enough?

• Are you sure you pressed the START button?

• Perhaps the PSR-300M is in the SYNCHRO START
mode, so all you have to do is start playing.

4. PROBLEM

• Auto accompaniment won’t function. No lower key

board sound.

CHECK

• Auto accompaniment won’t function if the FINGERED
mode is selected and you’re using SINGLE FINGER
type fingering or improper chord fingering.

• Are you sure you’re playing in the left-hand section of
the keyboard when the FINGERED or SINGLE FIN
GER mode is selected?

• The left-hand section of the keyboard will produce no
sound if synchro start is disengaged in the FINGERED
or SINGLE FINGER mode.

5. PROBLEM

• The accompaniment key changes while you’re playing.

CHECK

• Perhaps you accidentally pressed a key in the left-hand
range.

6. PROBLEM

• Auto accompaniment chords don’t seem to change prop
erly.

CHECK

• Arc you playing chords that the PSR-300M can recog
nize (see fingering chart on page 19)?

7. PROBLEM

• The sound is distorted or intermittent.

CHECK

• In this case, your batteries are probably flat and need
replacement.

17

TROUBLESHOOTING

SPECIFiaTIONS

8. PROBLEM

• Sustain produces little or no effect.

CHECK

• The sustain effect may not sound as deep as it normally
does when used during accompaniment or demo
