PROFILE OF THIS UNIT

You are the proud owner of Yamaha DSP-E390 an extremely sophisticated audio component. The Digital Sound Field Processor (DSP) built into this unit takes full advantage of Yamahas undisputed leadership in the field of digital audio processing to bring you a whole new world of listening experiences. Follow the instructions in this manual carefully when setting up your system, and this unit will sonically transform your room into a totally new listening environment movie theater, concert hall, and so on. In addition, you get incredible realism from Dolby Surround-encoded video sources using the built-in Dolby Pro Logic Surround Decoder. Please read this operation manual carefully and store it in a safe place for later reference.
Digital Sound Field Processing
What is it that makes live music so good? Todays advanced sound reproduction technology lets you get extremely close to the sound of a live performance, but chances are youll still notice something missing: the acoustic environment of the live concert hall. Extensive research into the exact nature of the sonic reflections that create the ambience of a large hall has made it possible for Yamaha engineers to bring you this same sound in your own listening room, so youll feel all the sound of a live concert. Furthermore, our technicians, armed with sophisticated measuring equipment, have even made it possible to capture the acoustics of a variety of venues such as an actual concert hall, theater, etc. to allow you to accurately recreate one of several live performance environments in your own home.

Dolby Pro Logic Surround

The Dolby Pro Logic Surround Decoder program lets you experience the dramatic realism and impact of a Dolby Surround movie theater sound in your own home. Dolby Pro Logic gets its name from its professional-grade steering logic circuitry, which provides greater effective front and rear channel separation for a much higher degree of realism than the passive Dolby Surround circuits found in less sophisticated home audio/video equipment. Dolby Pro Logic Surround provides a true center channel, so there are four independent channels, unlike passive Dolby Surround which has in effect only three channels: left, right, and rear. This center channel allows listeners seated in even less-than-ideal positions to hear the dialog originating from action on the screen while getting a stereo effect as well. This Dolby Pro Logic Surround Decoder employs a digital signal processing system. This system increases sound stability at each channel and minimizes crosstalk between channels compared to conventional analog Dolby signal processing. In addition, this unit features a built-in automatic input balance control. This circuit always presents you the best surround conditions without performing manual adjustments.

Dolby Pro Logic Surround + DSP
You can also enjoy a combination of Dolby Pro Logic Surround and DSP in the sound field program PRO LOGIC ENHANCED. It recreates the surround effect of a movie theater, effectively duplicating its multiple surround loudspeaker system, completely surrounding the listener with the sounds of the action taking place on the screen.

SPEAKER SETUP

SPEAKERS TO BE USED
This unit is designed to provide the best sound-field quality with a 5 speaker configuration. The most effective speakers to use with this unit are front speakers, rear speakers and a center speaker. You may omit the center speaker. (Refer to the 4-Speaker Configuration shown below.) The front speakers are used for the main source sound plus the effect sounds. They will probably be the speakers from your present stereo system. The rear speakers are used for the effect and surround sounds, and the center speaker is for the center sounds (dialog etc.) within the Dolby Surround encoded programs. The center speaker needs to be equal in power to the front speakers, although the rear speakers should not be equal. However, all the speakers should have high enough power handling to accept the maximum output of this unit.

SPEAKER CONFIGURATION

5-Speaker Configuration
This configuration is the most effective and recommended one. In this configuration, the center speaker is necessary as well as the rear speakers. If the digital sound field program DOLBY PRO LOGIC or DOLBY PRO LOGIC ENHANCED is selected, conversations will be output from the center speaker and the ambience will be excellent. q Set the center channel mode to the NORMAL or WIDE position. (For details, refer to page 10.) Front L Center Front R

4-Speaker Configuration

The center speaker is not used in this configuration. If the digital sound field program DOLBY PRO LOGIC or DOLBY PRO LOGIC ENHANCED is selected, the center sound is output from the left and the right front speakers. However, the sound effect of other programs can be the same as that of the 5-speaker configuration. q Be sure to set the center channel mode to the PHANTOM position. (For details, refer to page 10.) Front L Front R

Notes q Once you have completed these adjustments, you can adjust whole sound level on your audio system by using the VOLUME control (or the MASTER VOLUME keys on the remote control transmitter). q If you use external power amplifiers, their volume controls may also be adjusted to achieve proper balance. q In step 8, if the center channel mode is in the PHANTOM position, the sound output level of the center speaker cannot be adjusted. This is because in this mode, the center sound is automatically output from the left and right front speakers. q If there is insufficient sound output from the center and rear speakers, you may decrease the front channel output level by setting the FRONT LEVEL switch on the rear panel to 10 dB.
USING DIGITAL SOUND FIELD PROCESSOR (DSP)
This unit incorporates a sophisticated, multi-program digital sound field processor, which allows you to expand and shape the audio sound field from both the audio and video sources, for a theater-like experience in the listening/viewing room. This digital sound field processor has 6 programs; 4 programs for digital sound field processing and 2 programs for the Dolby Pro Logic Surround sound system (DOLBY PRO LOGIC and DOLBY PRO LOGIC ENHANCED). You can create an excellent audio sound field by selecting the suitable program and adding desired adjustments. In addition, when the DOLBY PRO LOGIC or DOLBY PRO LOGIC ENHANCED program is selected, the built-in automatic input balance control functions. This presents you the best surround condition without manual adjustment.

Description of Each Sound Field Program
The following list gives brief descriptions of the sound fields produced by each of the DSP programs. Keep in mind that most of these are precise digital recreations of actual acoustic environments. The data for them was recorded at the locations described using sophisticated sound field measurement equipment. Note The channel level balance between the left rear effect speaker and the right rear effect speaker may vary depending on the sound field you are listening to. This is due to the fact that most of these sound field recreations are actual acoustic environments. PROGRAM FEATURE This program is effective for playback of sources encoded with Dolby Surround. The employment of the digital signal processing system improves crosstalk and transfers the sound source more smoothly and precisely, compared to the conventional type. A stable movie sound field is recreated. This program is effective for playback of sources encoded with Dolby Surround. Enhancing the Normal Dolby Pro Logic, the DSP technology simulates the multi-surround speaker systems of a 35 mm film theater, thus widening the surrounded-sound field with greater presence. This program is effective for music videos and gives excellent depth and clarity for vocals. For opera, the orchestra and stage are ideally recreated, letting you feel as if you were in an actual concert hall. This program is designed specifically to enhance mono source programs. Compared to a strictly mono setting, the sound image created in this mode is wider and slightly forward of the speaker pair, lending an immediacy to the overall sound. It is particularly effective when used with old mono movies, news broadcasts and dialog. This program is suitable for rock music. A big, powerful sound is reproduced lively and dynamically. In this program, the center seems deep behind the front speaker pair, creating an expansive, large hall ambience.

PRO LOGIC ENHANCED

ROCK CONCERT CONCERT HALL
Description of Dolby Pro Logic Surround
DOLBY PRO LOGIC SURROUND: This unit employs the Dolby Pro Logic Surround system. This system is similar to professional Dolby Stereo decoders used in movie theaters. By employing a four-channel system, the Dolby Pro Logic Surround system divides the input signals into four levels: the left and right main channels, the center channel (to characterize dialog), and the rear surround-sound channels (to characterize sound effects, background noise and other ambient noise). Dolby Surround is encoded on the sound track of commercially available video cassettes and video discs as well. When you play a source encoded with Dolby Surround on your home video system, the Dolby Pro Logic Surround system in this unit decodes the signal and feeds the surround-sound effects. The Dolby Pro Logic Surround mode may not be always effective on video sources not encoded with Dolby Surround.

When CONCERT VIDEO, MONO MOVIE, ROCK CONCERT or CONCERT HALL is selected, no sound is heard from the center speaker.
Adjustment of the CENTER LEVEL
If desired, you can adjust the sound output level of the center speaker even if the output level is already set in SPEAKER BALANCE ADJUSTMENT on page 11.
If the digital sound field program CONCERT VIDEO, MONO MOVIE, ROCK CONCERT or CONCERT HALL is selected, this adjustment is useless. Once the output level is adjusted, the level value will be the same in the DOLBY PRO LOGIC and DOLBY PRO LOGIC ENHANCED programs. If no program is used, this adjustment is useless.
Adjustment of the REAR LEVEL
If desired, you can adjust the sound output level of the rear speakers even if the output level is already set in SPEAKER BALANCE ADJUSTMENT on page 11.
Once the output level is adjusted, the level value will be the same in all the digital sound field programs. If no program is used, this adjustment is useless.

Adjustment of DELAY TIME

You can adjust the time difference between the beginning of the source sound and the beginning of the effect sound with the DELAY TIME keys. The DELAY TIME keys are effective with all programs. By applying more or less delay, sound effects, background noise, and ambient noise coming at you from the rear speakers can be enhanced or subdued for extra effect. 1. : from 15 to 30 milliseconds (Preset value: 20 milliseconds) 2. PRO LOGIC : from 15 to 30 milliseconds ENHANCED (Preset value: 20 milliseconds) 3. CONCERT VIDEO : from 1 to 100 milliseconds (Preset value: 25 milliseconds) 4. MONO MOVIE : from 1 to 100 milliseconds (Preset value: 25 milliseconds) 5. ROCK CONCERT : from 1 to 100 milliseconds (Preset value: 15 milliseconds) 6. CONCERT HALL : from 1 to 100 milliseconds (Preset value: 30 milliseconds) PRO LOGIC
By continuously pressing + or key, the value changes continuously. However, the value stops changing momentarily at the preset point.

Adjustable

Notes q Adding too much delay will cause an unnatural effect with some sources. Experiment with the DELAY TIME keys to create the effect that you find most suitable.
The values of the DELAY TIME you set the last time will remain memorized even when the power of this unit is off. However, if the power cord is kept disconnected for more than one week, these values will be automatically changed back to the original factory settings.
