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
Avoid excessive heat, humidity, dust and vibration
Keep the unit away from locations where it is likely to be exposed to high temperatures or
humidity - such as near radiators, stoves, etc. Also avoid locations which are subject to
excessive dirt accumulation or vibration which could cause mechanical damage.
Avoid physical shocks
Strong physical shocks to the unit can cause damage. Handle it with care.
Do not open the unit, or attempt repairs or modifications yourself
This product contains no user-serviceable parts. Refer all maintenance to qualified Yamaha
service personnel. Opening the unit and/or tampering with the internal circuitry will void
the warranty.
Make sure power is off before making or removing connections
Always turn the power OFF prior to connecting or disconnecting cables. This is important
to prevent damage to the unit itself as well as other connected equipment.
3 – Precautions
Handle cables carefully
Always plug and unplug cables - including the AC cord - by gripping the connector, not the
cord.
Clean with a soft dry cloth
Never use solvents such as benzine or thinner to clean the unit. Wipe clean with a soft, dry
cloth.
Always use the correct power source
Make sure that the power source voltage specified on the rear panel matches your local AC
mains supply:
U.S. & Canadian Model: 120V AC, 60Hz
General Model: 230V AC, 50Hz
UK and Australian Model: 240V AC, 50Hz
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!

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 transmis-
sion cable) for connection with periphery equipment.
Using general analog audio cable (impedance 40 ~ 50 Ω shield type equilibrium trans-
mission 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.

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 3). 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 PRO-
TECT” will disappear from the screen.

key
7 – Using the display
Guide to the screen displays:
The
[L/<]
and
[R/>]
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.
