Panel logos
The logos printed on the PSR-550 panel indicate standards/
formats it supports and special features it includes.
GM System Level 1
“GM System Level 1” is an addition to the MIDI standard
which guarantees that any data conforming to the standard will
play accurately on any GM-compatible tone generator or
synthesizer from any manufacturer.
XG
XG is a new Yamaha MIDI specification which significantly
expands and improves on the GM System Level 1 standard
with greater voice handling capacity, expressive control and
effect capability while retaining full compatibility with GM.
By using the PSR-550’s XG voices, it is possible to record
XG-compatible song files.
DOC
The DOC voice allocation format provides data playback
compatibility with a wide range of Yamaha instruments and
MIDI devices, including the Clavinova series.
Style File Format
The Style File Format — SFF — is Yamaha’s original style
file format which uses a unique conversion system to provide
high-quality automatic accompaniment based on a wide range
of chord types. The PSR-550 uses the SFF internally, reads
optional SFF style disks, and creates SFF styles using the
Style Recording feature.
Music stand
The PSR-550 is supplied with a music stand that can be attached
to the instrument by inserting it into the slot at the rear of the
control panel.
The sustain function lets you produce a natural
sustain as you play by pressing a footswitch. Plug
an optional Yamaha FC4 or FC5 footswitch into
this jack and use it to switch sustain on and off.
The footswitch connected to this jack can also be
set to replicate the functions of some panel buttons,
doing things like starting and stopping accompaniment (page 121).
• Be sure that you do not press the footswitch while turning the power
on. If you do, the ON/OFF status of the footswitch will be reversed.
• When the sustain or sostenuto pedal functions are being used
(page 121), some voices may sound continuously or have a long
decay after the notes have been released while the pedal is held.

Setting Up
This section contains information about setting up your PSR-550 and preparing to play.
Be sure to go through this section carefully before turning the power on.
Power supply connections
Although the PSR-550 will run either from an optional AC adaptor or batteries, Yamaha recommends use of the
more environmentally safe AC adaptor. Follow the instructions below according to the power source you intend
to use.
■ Using An Optional AC Power Adaptor
1
Make sure that the STANDBY/ON switch
of the PSR-550 is set to STANDBY.
CAUTION
• Never interrupt the power
supply (e.g. remove the
batteries or unplug the AC
adaptor) during any PSR-550
record operation! Doing so
can result in a loss of data.
2
Connect the AC adaptor (PA-6 or other
adaptor specifically recommended by
Yamaha) to the power supply jack.
3
Plug the AC adaptor into an AC outlet.
When turning the power OFF, simply reverse
the procedure.
■ Using Batteries
For battery operation the PSR-550 requires six 1.5V “D” size, R20P (LR20) or
equivalent batteries. When the batteries need to be replaced, “Battery Low” may
appear on top of the display, the volume may be reduced, the sound may be
distorted, and other problems may occur. When this happens, turn the power off
and replace the batteries.
Replace the batteries as follows:
1
Open the battery compartment
cover located on the instrument’s
bottom panel.
2
Insert the six new batteries, being
careful to follow the polarity
markings on the inside of the
compartment.
WARNING
• Use ONLY a Yamaha PA-6 AC
Power Adaptor (or other
adaptor specifically recommended by Yamaha) to power
your instrument from the AC
mains. The use of other
adaptors may result in
irreparable damage to both
the adaptor and the PSR-550.
• Unplug the AC Power Adaptor
when not using the PSR-550,
or during electrical storms.
CAUTION
• When the batteries run down,
replace them with a complete
set of six new batteries.
NEVER mix old and new
batteries.
• Do not use different kinds of
batteries (e.g. alkaline and
manganese) at the same time.
• If the instrument is not to be
in use for a long time, remove
the batteries from it, in order
to prevent possible fluid
leakage from the battery.
• Plugging or unplugging the
AC power adaptor while the
batteries are installed will
reset the PSR-550 to the
defaults.
3
Replace the compartment cover,
making sure that it locks firmly in
place.
Important Notes on Battery Use
• Since the PSR-550 consumes a considerable amount of power,
Yamaha recommends the use of an AC power adaptor rather than
batteries. The batteries should be considered an auxiliary power
source for data backup.
• The floppy disk drive, in particular, uses a large amount of power, so
it is important to always use an AC power adaptor when performing
disk-intensive operations such as song recording/playback or data
12
load/save. If you attempt to use battery power for these operations
and the batteries do fail, you will lose not only the data you’re
recording or saving, but also other data in internal memory including
user styles, user pads, registration memory, etc.
• Taking the above precautions into consideration, always use an AC
power adaptor when using the PSR-550 for an important performance or when creating important data.

Basic Operation
This section introduces you to the basic operations common to the various functions of the PSR-550.
In particular, you’ll learn how to use the menu/message display at the center of the front panel.
• Calling up the Operation Displays .....................................................................page 17
• How to read the Menu/message display and the “Easy Navigator” ................... page 18
• Menu Selection.................................................................................................. page 19
• FUNCTION button ............................................ page 118
• DISK LOAD button............................................. page 62
• DISK SAVE button ............................................. page 60
• DISK UTILITY button ................................. pages 64, 67
Pressing one of these buttons instantly calls up the relevant display for the selected
function.
See the function tree chart for details (page 22).
If you’ve selected several different functions’ displays in succession, you can “retrace
your steps” and revisit each display by using the [BACK] and [NEXT] buttons at the
left side of the display. Of course you can also directly select the desired displays by
pressing the appropriate buttons (as listed above).
How to leave the current display
As shown in the function tree chart (page 22), there is a wide varierty of functions on
the PSR-550, each with its own corresponding display. In order to leave the display of
each function press the [EXIT] button.
Since the PSR-550 has so many different displays, you may occasionally find yourself
confused as to which operation’s display is currently shown. If this happens, you can
return to “home base” by pressing the [EXIT] button several times. This returns the
PSR-550 to the default display — the same display that appears when the power is
turned on.

In this case you can also select the voice by using the data dial or the [+/YES]/[-/NO]
buttons as above; you can also input the voice number directly by using the number
buttons [1]-[0] (see the next page).

Basic Operation
Changing (Editing) Values
This section shows you how to set numeric values on the PSR-550, such as voice
number, song/style number and various parameters. Input the values by using the
number buttons [1]-[0] or the [+/YES]/[-/NO] buttons.
Number buttons [1]-[0]
described below.
Rotating the data dial
to the right (clockwise)
increases the value,
while rotating it to the
left (counter-clockwise) decreases it.
Pressing the [+/YES] button increases the displayed
value by 1. Pressing the [-/NO] button decreases the
displayed value by 1. Pressing and holding either button
causes a continuous increase and decrease.
For items that have initial default values, pressing the [+/
YES] and the [-/NO] buttons together at the same time
will return the setting to the initial value.
Numeric entry
The explanations here apply only to numbers that have a maximum of three digits,
such as those for voices and styles.
• Entering one- or two-digit numbers
One- or two-digit voice numbers can be entered with leading zeroes: e.g. “12” can be
entered as “012” by pressing the [0], [1] and [2] buttons in sequence.
• One- or two-digit numbers
can also be entered without
leading zeroes.
To select number “12”, for
example, simply press the [1]
button and then the [2]
button. The bars below the
number on the display will
flash for a few seconds, and
then disappear when the
selected number has been
recognized by the PSR-550.
• Entering three-digit numbers
The number buttons can be used to directly enter the number of the desired voice,
thereby immediately selecting that voice without having to step through a number of
other voices. To select number 106, for example, press the [1], [0] and [6] number
buttons in sequence.

Naming
The allows you to create your own original data such as songs, styles and registration
memory settings. You can also freely name the data as desired.
The following data types can be named.
The example display below appears when naming a song on a floppy disk (page 90).
–Nam=xxxxxxxx
Cursor
To enter an original name, use the keyboard.
Letters and characters are marked
above the corresponding keys.
Basic Operation
C1
Entering a characterEach key on the keyboard enters a different character, as
marked directly above the ke y.
Moving the cursorThe A#5 and B5 keys move the cursor backward and
forward within the file name.
Entering a lower-case characterThe C1 key functions as a shift key that shifts between
lower- and upper-case characters: hold the Shift key
while pressing a character key to enter the lower-case
character.
DeleteThe Delete key (C6) deletes the character at the cursor
position.
Direct Access
By using the [DIRECT ACCESS] button, you can instantly call up the desired display.
For example, pressing the [DIRECT ACCESS] button and press the
[REGISTRARTION MEMORY] button automatically selects the display for inputting the Registration Memory bank name.
• Lowercase letters cannot be
used for disk file names.
