2 – Congratulations –
Congratulations
Your new YDG2030 Digital Graphic Equalizer uses the most advanced Yamaha digital signal processing to provide extremely precise, stable equalization.
As well as a stereo 30 band graphic equalizer, YDG2030 Digital Graphic Equalizer has a high
and low pass filter, and 4 notch filters which can be used to selectively “knock out” specific
frequencies.Furthermore, the unit can operate at either 6 or 12dB cut/boost.
If you are used to using conventional analog graphic equalizers with sliders, you will find
the YDG2030 very easy to use. Selecting “sliders” and “moving” them are simple operations
performed with rotary encoders on the front panel. With a multi-function LCD screen, you
can see at a glance exactly which “slider”, or notch filter you are moving. Or if you prefer,
you can change to a purely numeric display for the notch filter parameters.
One of the biggest advantages of Yamaha digital equalizers (apart from their stunning 20 bit
sound) is the ability to store the equalizer settings you create for instant recall. The YDG2030
has the ability to store 40 different settings in this way, avoiding the need to completely
reconfigure the sliders every time the unit has to be used for a different purpose, or in
another environment.
In order to satisfy the most demanding needs of music professionals, the YDG2030 is able to
be controlled not only by MIDI, but also by the new standard Y-485 interface. This allows for
the fastest possible system configuration, without having to use up an extra MIDI channel to
send program changes.
We urge you to read this manual carefully before using this unit, in order to fully appreciate,
and be able to take advantage of, the many advanced features it offers.

Precautions
3 – Precautions
Warnings
1. Connect this unit’s power cord only to an AC
outlet of the type stated in this Owner’s Manual or as marked on the unit. Failure to do so is
a fire and electrical shock hazard.
2. Do not allow water to enter this unit or allow
the unit to become wet. Fire or electrical shock
may result.
3. Do not place heavy objects, including this unit,
on top of the power cord. A damaged power
cord is a fire and electrical shock hazard. In
particular, be careful not to place heavy objects
on a power cord covered by a carpet.
4. Do not place a container with liquid or small
metal objects on top of this unit. Liquid or
metal objects inside this unit are a fire and electrical shock hazard.
5. Do not remove the unit’s cover. You could
receive an electrical shock. If you think internal
inspection, maintenance, or repair is necessary,
contact your dealer.
6. Do not modify the unit. Doing so is a fire and
electrical shock hazard.
7. If lightning begins to occur, turn off the power
switch of the unit as soon as possible, and
unplug the power cable plug from the electrical
outlet.
If there is a possibility of lightning, do not
touch the power cable plug if it is still connected. Doing so may be an electrical shock
hazard.
8. If the power cord is damaged (i.e., cut or a bare
wire is exposed), ask your dealer for a replacement. Using the unit with a damaged power
cord is a fire and electrical shock hazard.
9. If you notice any abnormality, such as smoke,
odor, or noise, or if a foreign object or liquid
gets inside the unit, turn it off immediately.
Remove the power cord from the AC outlet.
Consult your dealer for repair. Using the unit
in this condition is a fire and electrical shock
hazard.
10. Should this unit be dropped or the cabinet be
damaged, turn the power switch off, remove
the power plug from the AC outlet, and contact
your dealer. If you continue using the unit
without heeding this instruction, fire or electrical shock may result.
Cautions
1. Keep this unit away from the following locations:
Locations exposed to oil splashes or steam,
such as near cooking stoves, humidifiers, etc.
Unstable surfaces, such as a wobbly table or
slope.
Locations exposed to excessive heat, such as
inside a car with all the windows closed, or
places that receive direct sunlight.
Locations subject to excessive humidity or
dust accumulation.
2. Do not place the power cord close to a heater. It
may melt, causing fire or electrical shock.
3. Hold the power cord plug when disconnecting
it from an AC outlet. Never pull the cord. A
damaged power cord is a potential fire and

unit. Use the correct connecting cables and connect as specified.
Always lower the volume control to minimum
before turning on the power to this unit. A sudden blast of sound may damage your hearing.
7. Do not output distorted sounds for long periods of time, as this will cause the speaker to
heat up, leading to a fire hazard.
8. If you know you will not use this unit for a
long period of time, such as when going on
vacation, remove the power plug from the AC
outlet. Leaving it connected is a potential fire
hazard.
9. To prevent electrical shock when cleaning the
unit, remove the power plug from the AC outlet.
10. The inside of the unit should be cleaned periodically. Dust accumulation inside the unit
may cause malfunction and is a potential fire
hazard. Consult your dealer for information
about cleaning.
Backup battery
The unit contains a long-life lithium battery which maintains the contents of the buffer and user
memory locations even when the unit is off. With normal use, the battery should last approximately 5
years. If the battery voltage falls below a certain level, a “***WARNING*** LOW BATTERY” message
will appear on the screen when the power is turned on. If this occurs, have the battery replaced by at
a qualified Yamaha service center. Do not attempt to replace the battery yourself!

1 Y-485 – these bi-directional connectors are used to connect the unit on a network “chain”
using the Y-485 control protocol. They do not carry audio signals. When making a Y-485
connection, either terminal may be used for IN or OUT.
Please use digital audio cable (impedance 90 ~ 120 Ω shield type equilibrium transmission cable) for connection with periphery equipment.
Using general analog audio cable (impedance 40 ~ 50 Ω shield type equilibrium transmission cable) could cause trouble such as signal reflection due to mismatching impedance and transmission waveform turbulence.
Waveform turbulence is especially noticeable with long cables, and with multi cable
longer than 10 meters.
If the length of the cable is longer than 100 meters, it is recommended that it should be
terminated with a resistor matching the impedance of the cable (connect a resistor of
approx. 100 Ω between Pin 2 and Pin 3).
2 MIDI IN, OUT and THRU – these terminals are used for MIDI control of the unit. IN is
used to receive MIDI data, THRU passes along information received at the IN terminal,
and OUT transmits data originated by the unit.
3 OUTPUT (L, R) – these balanced XLR-type connectors output the signal from the unit.
4 INPUT (L, R) – these balanced XLR-type connectors are used to input signals to the unit.
5 Level switches – both the input and output connectors may be set to nominal levels of
+4dB or -20dB. When connecting other equipment, refer to the specifications of the other
units to match the signal levels correctly.
YDG2030
6 – Memory areas
Memory areas
How the memories are arranged in the YDG2030
The unit contains 40 memory areas which contain equalization settings, all of which are
user-programmable. This allows you to set up and store frequently-used equalization settings which you can recall at any time. These settings can be stored to a mass-storage device
(MIDI data file system or personal computer system) either through the MIDI interface, or
the Y-485 connectors (see the section on “Utilities” for full details of this).
Recalling an equalization setting
Use the MEMORY [^] and [%] keys to display the name of the setting you want to recall. The
name (set in UTILITY mode) is shown in the middle of the display, and the memory number
flashes on the LED display.
Press the [RECALL] key.
If you had not made any changes to the previous setting, the new setting will be displayed
immediately.
If you had made changes to the previous setting without storing them, the unit will flash
“RECALL OK?” in the center of the screen. If you really want to recall this setting, press the
[RECALL] key again (while this message is flashing, you can use the MEMORY [^] and [%]
keys to select another setting to be recalled). If you press the [RECALL] key, the number in the
LED will stop flashing, and the screen will show the equalization curve for this setting. If
you have made a mistake in selecting the setting or pressing the [RECALL] key in the first
place, and do not want to recall the setting, press any key except the [RECALL] key.
Remember that the equalization curve shown will be for either the left or the right channel,
depending on whether the [L/<] or [R/>] key is lit.
Storing an equalization setting
When you have edited a setting, you use the MEMORY [^] and [%] keys to select a memory
area where you want to store the setting (if the memory area you are editing is the area
where you want to store the setting, you do not need to press the [^] and [%] keys). As you
step through the memory areas, the name of each one will be displayed in the center of the
screen.
When you have selected the area, press the [STORE] key to write these settings into memory.
The unit will flash “STORE OK?” in the center of the screen. Press the [STORE] key again to
confirm the store, or any other key to cancel the store.
A note on software protection
You can protect the settings against accidental key-presses, etc., by using the UTILITY software protection (see “SOFTWARE PROTECT” on page 11). If protection is set to ON, then
any attempt to store or recall settings using the methods described above will result in the
message “ERR ** NOW PROTECT” being shown on the screen. The 2-digit LED will start to
flash if you attempt to recall, store or modify a setting with protection on, as an additional
warning. If you get the “ERR ** NOW PROTECT” message when trying to perform any
operations with protection on, press any key to stop the LED flashing. “ERR ** NOW PROTECT” will disappear from the screen.
YDG2030
Using the display
The [DISPLAY]key
Using the large LCD screen, your YDG2030 has several different ways of displaying settings, and being able to edit them. These different modes are accessed with the [DISPLAY] key,
as shown:
Press the [DISPLAY] key to change from one display to the next.
NOTE
Only one channel can be displayed on the screen at a time.
7 – Using the display
Guide to the screen displays:
The [L/<] and [R/>] keys
Each of the above displays can show either the settings for the left channel, or the settings
for the right channel. To select which channel will be displayed, press the [L/<] or [R/>] key.
The LED on the corresponding key will light up, the display will change to show the new
channel, and either R or L will appear in the top left of the screen.
Linking channels
In order to change both the L and R channels at the same time, the L and R channels must be
linked. When the channels are linked, making any changes to one channel will also affect the
other. Existing parameters from one channel will not be copied to the other channel, unless
they are altered while the channels are linked.
To link the channels, press one of the two channel keys (either [L/<] or [R/>]), and while holding it down, press the other one. Because the screen can only show one channel at a time,
only the settings of the first channel you pressed will be displayed, and the LED on that key
will light. The settings of the other channel will not be displayed, and its LED will blink.
