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.
3 – Precautions Precautions Warnings Cautions 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.

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.
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.
7 – Using the display 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.
8 – Using the display – The notch filter, and HPF and LPF indicators The notch filter, and HPF and LPF indicators NOTCH 1 2 3 4 HPF LPF The small round LEDs above each notch and filter selector indicate whether or not the corresponding notch or filter is active (turned on). If the indicator is on, the notch or filter is active. To turn a specific notch or filter on or off while in an equalizer, sweep or notch screen, it must first be selected for editing.
9 – Utilities Utilities The [UTILITY] key allows you to set up various system parameters for the unit. Repeated presses of the key will cycle you through the following modes. You can also use the [%] and [%] keys to cycle through these parameters (but this will not return to the equalization setting display): The [UTILITY] key will be lit for all these displays SYSTEM SET UP TITLE EDIT BULK DUMP Y-485 NETWORK Equalization setting display Y-485 COMM.
10 – Utilities – BULK DUMP BULK DUMP Three parameters are available here: Use the F encoder to select whether bulk dump operations will take place through the MIDI or Y-485 connections. Use the G encoder to select what kind of data will be dumped. You can choose between: ALL DATA (all memory areas will be dumped), SYSTEM (the parameters you set up in the UTILITY menus will be dumped), MEMORY (a single memory area, or all memory areas will be dumped), and BANK (the Program Change tables).
11 – Utilities – Y-485 COMM. I/O Y-485 COMM. I/O Only one parameter is available here: the data which will be recognized by the unit over the Y-485 network. There are three values, selectable with the F encoder: OFF, PGM CHANGE and ALL. When OFF, no Y-485 messages will be recognized by the unit, when PGM CHANGE, only Program Change messages will be recognized by the unit, and when ALL, any data coming over the Y-485 interface will be recognized.
12 – Utilities – MIDI CONTROL MIDI CONTROL The unit will respond to MIDI Program Change messages sent from a master keyboard, sequencer or other device. It may be useful to remap program change settings so that a Program Change message of 2, for instance, selects memory area 40. There are four “banks” of Program Change tables available – A through D. Use the [L/<] and [R/>] keys to select which bank will be edited.
13 – TUTORIAL TUTORIAL In this section we will go over the setting up of the YDG2030, from the graphic equalizer and the filters, to the delay and input attenuation. The information is presented as a tutorial— from it, you should be able to pick up the techniques necessary to make settings for any situation. Finding a suitable memory area in which to store the setting This may be an existing equalization setting which you wish to alter, or a completely new setting that you wish to create from scratch.
14 – TUTORIAL – Linking the L and R channels 4 Press the [DISPLAY] key to return to the equalization screen. NOTE This operation will clear the entire contents of the current memory area. Don’t do this to settings you wish to keep. Linking the L and R channels Frequently you will want to set up the L and R channels identically (at least for most of the settings), and then tweak the L and R channels separately. Linking the channels is the way to achieve this.
15 – TUTORIAL – Using the sweep function 4 Once you have created the desired settings, don’t forget to store them inside one of the memory areas, so you can use them again at a later time. Using the sweep function The sweep function allows you to move a given gain cut or boost through a number of different frequencies quickly and easily.
16 – TUTORIAL – Using the notch filters, and the HPF and LPF Example II: “Tuning” a room One method of “tuning” a room (compensating for dead and live frequencies) with a conventional graphic equalizer is to move the faders up and down one at a time while putting white noise through the sound system. Then, if “ringing” is heard at any particular frequency, you can reduce the gain of that frequency. Likewise, if a particular frequency seems to get lost, you can increase its gain.
17 – TUTORIAL – Using the notch filters, and the HPF and LPF II. Editing the filters graphically 1 Press the [DISPLAY] key until you see a screen similar to the one here. (It comes immediately after the SWEEP screen.) The actual settings on your screen will probably be different to the ones shown here. 2 To select a filter for editing (if it’s not already selected), press one of the notch or filter selectors.
18 – TUTORIAL – Setting up the input level, attenuation and delay Setting up the input level, attenuation and delay I. Input level and input attenuation There are two operations on the YDG2030 that affect the input level—the input level control in the analog domain (pre A/D converters), and the attenuation parameter (INP.ATT) in the digital domain (post A/D converters).
19 – Specifications Specifications 20Hz to 20kHz 0 ±1, 0dB Frequency response Dynamic range Emphasis ON typical, 110dB > 104dB Emphasis OFF typical, 106dB > 100dB Hum and noise Distortion Inputs Outputs A/D and D/A convertors Emphasis ON < -80dBm Emphasis OFF <-76dBm (max level, Emphasis ON) < 0.007% (max level, Emphasis OFF) <0.
