Welcome
Welcome to the DX7s, the newest member of the growing family of FM digital
synthesizers from Yamaha. Using the industry-standard DX7 as its starting point, the
DX7s offers a number of important new features, such as improved sound quality,
additional FM features, new performance options, and improved controls.
Since there is so much material available on the DX7 family of synthesizers (and on the
theory of FM digital synthesis), this manual will not be an FM tutorial. Instead, it has
been designed to be a “users manual” in the truest sense — its goal is to help you make
music with your new DX7s as quickly as possible.
If you are already familiar with the operation of the original DX7, this manual will help
you make the transition to the DX7s in short order. On the other hand, if this is your first
FM digital instrument, this manual will guide you into the operation of your new
synthesizer with easy-to-follow, step-by-step instructions and explanations.
After you are comfortable with the operation of your new synthesizer, you may want to
explore the fascinating world of FM digital voicing. If so, consult the extensive list of
reference works on FM synthesis listed in the bibliography at the back of this manual.
Tips
The DX7s has been designed for years of trouhle-free use. In order to ensure that it
remains a healthy member of your family
following tips in mind:
of
musical instruments, please keep the
Installation:
When setting up the DX7s in your home or studio, avoid exposure to direct sunlight or
other sources of heat. Environments with excessive dust, cold, dampness, or vibration can
also damage your instrument. Even though the DX7s is electronic, you should treat it with
the same kind of care you would lavish on any other musical instrument.
Also, since the DX7s is electronic, you should make sure not to set it too close to
equipment (such as a television set) that generates electromagnetic fields. Such proximity
could cause both malfunctions in the synthesizer’s digital circuitry and interference noise
in the other unit.
Handling:
The DX7s is sturdy, but it can do without rough handling. Don’t subject it to sudden jolts
(such as dropping it), as this can damage the internal circuitry. If you plan to travel with it,
be sure to use a road case. Also, make sure not to apply excessive force to any of the keys,
buttons, or other controls.
Cleaning:
To clean or dust your DX7s, use nothing more than a clean, slightly damp cloth. Using
chemical solvents will damage the finish, and using too much water may do considerable
damage to the internal circuitry.
AC Power & Other Equipment:
When you are using the DX7s with an amplifier or mixer that has unbalanced outputs,
connect both units to the same AC outlet to avoid hum.
If you use a number of electronic instruments in your setup, you may want to consult an
electrician, who can make sure that your system does not overtax the available power.
AC Power & Down Time:
Whenever the DX7s will not be used for an extended period of time, it is best to protect it
from potential disaster. Electrical storms and other natural or man-made disasters can give
rise to power surges, which may damage the digital circuitry of your DX7s — even if the
power is turned off. Either unplug your instrument when not in use, or invest in power
strips with surge protectors to safeguard all of your electronic equipment.
Service & Your Warranty:
The DX7s contains no user-serviceable parts. Opening it up or tampering with it in any
way will void the warranty, and may also lead you to experience some nasty electrical
shocks. If you have a problem with your instrument, please take it to an authorized
Yamaha service center.
Modifications & Your Warranty:
Unless you are assured to the contrary in writing, you should assume that any
modifications made to your DX7s will void the original product warranty. Therefore, you
should make sure that you receive a warranty (or some other kind of guarantee) from the
person or company that is responsible for the modification.

Getting
Started
Connecting the DX7s
to a single input
amplifier.
You can begin to enjoy your DX7s immediately, without poring through a lot of
complicated electronic theory. All you have to do is take the instrument out of the box and
proceed as follows:
Making Audio Connections
There are three different ways to connect the DX7s to sound reinforcement equipment.
The one you choose will depend on your situation:
you
1. If
have a monophonic (single input) amplifier such as a guitar amp, connect the
DX's output to the amp’s input (using a standard ¼” cable).
Using stereo headphones
with the DX7s.
2. If you are using a multi-channel mixer, connect the DX’s back-panel audio output to
one of your mixer’s inputs (using a ¼” cable).
3. If you are using a set of standard stereo headphones, plug them into the DX’s Phones
output.

The DX’s “welcome” display.
Turning on the DX7s
After you have made the audio connection of your choice, turn the DX7s on by pressing
the power switch located on the right side of the back panel. This is the first display you
will see on the main panel:
After a few seconds, this display will be replaced by the last Play Mode display selected
before the DX7s was turned off:
The DX’s next
initial display.
The LED’s will now display the voice or
performance number that was displayed
when the DX was turned off.
The LCD will now show the voice or
performance name which corresponds to
the number in the LED.

Volume Slider
Setting the Volume Slider
Since the volumes of the various voices differ, start with a setting in the middle of the
slider’s range; adjust later to suit your taste, depending on the voice or voices being
played.

Setting the
ROM Cartridge
Banks
The ROM Cartridge supplied with your DX7s actually contains several sets of data —
called “banks.” These banks can be selected from the front panel. In order to hear all of
the Voice and Performance data, you will need to set the Voice/Performance bank to 2.
Also, certain voices in the DX7s are created using the new fractional scaling feature.
These scalings are stored in bank 3 of the ROM cartridge, so the Fractional Scaling Bank
will need to be set to bank 3. Look at the diagram on the next page and make the
necessary changes before you begin playing.
Inserting the ROM Cartridge
Before you begin to play your DX7s, insert the supplied ROM cartridge into the cartridge
slot:
