Surround Decoder.

Seven built-in channels of amplification on the DSP-A2070 mean that no additional

amplifiers are required to enjoy advanced digital sound field processing.

Rather than tell you about the wonders of digital sound field processing, however, let’s get

right down to the business of setting up the system and trying out its many capabilities.

Please read this operation manual carefully and store it in a safe place for later reference.

1-1. GETTING STARTED

Unpacking

If you haven’t already done so, carefully remove this unit and its

accessories from the box and wrapping material. You should find the

unit itself and the following accessories.

Installing the Remote Control Unit Batteries

Since the remote control unit will be used for many of this unit’s

control operations, you should begin by installing the supplied

batteries.

1. Turn the remote control unit over and slide the battery

compartment cover downward in the direction of the arrow.

2. Insert the batteries (LR6, AA, UM-3 type), being careful to align

them with the polarity markings on the inside of the battery

compartment.

3. Close the battery compartment cover.

SETUP & ADJUSTMENT

Batteries User program sheets

●

When you notice that remote control operation has become

erratic, or the distance from which the remote control will function

has decreased, it’s time to replace the batteries. Always replace

all batteries at the same time.

●

Make sure that the YPC/USER/LEARN switch on the remote

control unit is set to the YPC or USER position for normal

operation.

●

This remote control uses an advanced, highly directional infrared

beam. Be sure to aim the remote control directly at the remote

control sensor on the main unit when operating.

Remote control transmitter operation range

Notes

●

There should be no large obstacles between the remote

control transmitter and the main unit.

●

If the remote control sensor is directly illuminated by strong

lighting (especially an inverter type of fluorescent lamp etc.),

it might cause the remote control transmitter to work

incorrectly. In this case, reposition the main unit to avoid

direct lighting.

Digital Sound Field Processing

What is it that makes live music so good? Today’s advanced

sound reproduction technology lets you get extremely close to the

sound of a live performance, but chances are you’ll 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 you’ll feel all the sound of a live concert. What’s more, our

technicians, armed with sophisticated measuring equipment, have

even made it possible to capture the acoustics of a variety of actual

concert halls, jazz clubs, theaters, etc. from around the world, to

allow you to accurately recreate any one of these live performance

environments, all in your own home.

Dolby Pro Logic Surround

The Dolby Pro Logic Surround Decoder program lets you

experience the dramatic realism and impact of 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 channel separation for a much higher degree of realism than

the “passive” Dolby Surround circuits found in today’s typical home

audio/video equipment. Dolby Pro Logic Surround provides a true

center channel, so that 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 the action

on the screen while experiencing good stereo imaging.

This Dolby Pro Logic Surround Decoder employs a digital signal

processing system. This system improves the stability of sound at

each channel and crosstalk between channels, so that positioning of

sounds around the room is more accurate compared with

conventional analog signal processing systems.

In addition, this unit features a built-in automatic input balance

control. This always assures you the best performance without

manual adjustment.

Manufactured under license from Dolby Laboratories Licensing

Corporation. Additionally licensed under one or more of the

following patents: U.S. number 3,950,590; Canadian numbers

1,004,603 and 1,037,877. “Dolby”, “Pro Logic”, and the double-D

symbol are trademarks of Dolby Laboratories Licensing

Corporation.

Dolby Pro Logic Surround + DSP

You can also enjoy Dolby Pro Logic with two modes of Digital

Sound field processing. These combinations expand the surround

effect. One is the “ENHANCED” Dolby Pro Logic Surround, which

recreates the surround effect of the 35 mm film movie theater. The

other is the sound field program “MOVIE THEATER”, which recreates

the listening experience of a 70 mm film theater.

Directional Enhancement Circuit + DSP

The YAMAHA directional enhancement (DIR. ENHANCEMENT)

circuit expands and focuses the digital sound field.

This effect puts you in the midst of the action, while centering and

focusing your attention to the screen. This circuit is available on

Sound Field programs “CONCERT VIDEO” and “TV THEATER”.

Setting Up Your Speaker System

This unit has been designed to provide the best sound field

quality with a full seven-speaker system setup, using two extra pairs

of effect speakers to generate the sound field plus one center

speaker for dialog, when using Dolby Pro Logic Surround decoding.

We therefore recommend that you use a seven-speaker setup. A

four-speaker system using only one pair of effect speakers for the

sound field will still provide impressive ambience and effects,

however, and may be a good way to begin with this unit. You can

always upgrade to the full seven speaker system later. In the 4 or 5

speaker system, the Digital Sound Field Processing is still

performed, but the main speakers are used for both the main

channels and the front effect channels.

Use of the Center Dialog Speaker Is Recommended

With digital sound field programs No. 7 through No. 12, by using

either the Directional Enhancement circuit or the Dolby Pro Logic

decoder, decoded signals will be output from the center channel.

Therefore, if you want to upgrade the Audio/Video home theater

system, it is recommended to use the center speaker unit.

If for some reason it is not practical to use a center speaker, it is

possible to enjoy movie viewing without it. Best results, however, are

obtained with the full system.

It is also possible to further expand your system with the addition

of a subwoofer and amplifier. You may wish to choose the

convenience of a Yamaha Active Servo Processing Sub Woofer

System, which has its own built-in power amp.

Four Possible Types of Speaker System Configurations Recommended

4 Speaker System

Simplest system.

You can enjoy widely diffused sound by

only adding two additional speaker units

at the rear.

FRONT MIX switch—Set to ON.

(See page 13.)

Center Mode—Set to PHNTM.

(See page 26.)

5 Speaker System

Good for Audio/Video sources and

Dolby Pro Logic Surround.

With sound field programs No. 7

through No. 12, which utilize the center

speaker effect, more precise center

localization can be obtained.

FRONT MIX switch—Set to ON.

(See page 13.)

Center Mode—Set to NRML or WD.

(See page 26.)

6 Speaker System

Good for sound fields from 2-channel

stereo sources.

With sound field programs No. 1

through No. 6, a sound effect matching

that of a 7-speaker system can be

obtained. The addition of front left and

right effect speakers produces a more

effective sound field.

FRONT MIX switch—Set to OFF.

(See page 13.)

Center Mode—Set to PHNTM.

(See page 26.)

7 Speaker System

This is the recommended speaker

system, providing the best sound

effects.

With sound field programs No. 1

through No. 6, using both sets of effect

speakers (front and rear), reproduces

the most effective sound field. With the

sound field programs No. 7 through No.

12, the center speaker provides precise

center localization.

FRONT MIX switch—Set to OFF.

(See page 13.)

Center Mode—Set to NRML or WD.

(See page 26.)

Speakers and Speaker Placement

Your full seven-speaker system will require three speaker pairs:

the MAIN SPEAKERS (your normal stereo speakers), the FRONT

EFFECT SPEAKERS, and the REAR EFFECT SPEAKERS, plus the

CENTER SPEAKER. You may also be using a subwoofer.

You will probably use your present stereo speakers as the MAIN

SPEAKER pair. The front effect, rear effect do not need to be equal

with the MAIN SPEAKERS, although the center speaker should be

as close as possible. They should have enough power handling

capacity to accept the maximum output of the DSP system or the

external amps that will drive them.

Place the MAIN SPEAKERS in the normal position.

Place the FRONT EFFECT SPEAKERS further apart than the

MAIN SPEAKERS, on either side of and a few feet behind and above

the MAIN SPEAKER pair.

Place the REAR EFFECT SPEAKERS behind your listening

position. They should be nearly six feet up from the floor.

Place the CENTER SPEAKER precisely between the two MAIN

SPEAKERS. (To avoid interference, keep the speaker above or

below the television monitor, or use a magnetically shielded speaker.)

If using a SUBWOOFER, such as a Yamaha Active Servo Sub-

woofer System, the position of the speaker is not so critical because

low bass tones are not highly directional.

NOTE: The Yamaha NS-C90 speaker, available in some countries, is

an ideal choice for the center speaker.

CONNECTING THE MAIN SPEAKERS TO THIS UNIT

Connect the MAIN speakers to the MAIN speaker output

terminals of this unit. Make sure that the jumper bars between the

MAIN OUT and MAIN IN jacks on the rear panel are in place. It is

also possible to use an external power amplifier if more power is

desired. In this case, remove the jumper bars and connect the MAIN

OUT jacks to the INPUT jacks of a stereo power amplifier with a

stereo pin cable—making sure to connect the left and right channels

correctly. Connect the MAIN speakers to the speaker output

terminals of the power amplifier.

NOTE: If an external amplifier is used for the main speakers, it is

recommended to use the MAIN speaker terminals of this unit for the

rear effect speakers.

Connect the REAR EFFECT OUT jacks to the MAIN IN jacks with

the pin cord. This combination is highly upgraded and ideal for the

division of sound quality, because the rear channel output of the

Audio/Video system is equally important as the center channel.

CONNECTING THE EFFECT SPEAKERS TO THIS

UNIT

Connect the FRONT effect speakers to the FRONT effect

speaker output terminals of this unit.

If the FRONT effect speakers are not used, the FRONT MIX

switch should be set to “ON”.

Connect the REAR effect speakers to the REAR effect speaker

output terminals of this unit.

Connect the CENTER speaker to the CENTER speaker output

terminals. If you will be using one CENTER speaker, connect it to

either the A or B terminals and set the CENTER speaker impedance

switch to “A or B” (bottom position). If using two CENTER speakers,

connect them to the A and B terminals, and set the switch to “A + B”

(top position). If, however, you will not be using a CENTER speaker,

be sure to set the Center Mode to “PHNTM” (phantom). (See page

25.)

NOTE: The speaker connections above are fine for most

applications. If for some reason, however, you wish to use an

external power amp for any or all of the effect channels, connect the

line level output jack(s) for each channel to the INPUT jacks of the

external amp and connect the corresponding speaker pair to the

ADDING A SUBWOOFER

You may wish to add a subwoofer to reinforce the bass

frequencies.

This unit provides line-level subwoofer outputs, which contain only

the frequencies under 200 Hz from the main and center channels. If

you use one subwoofer, connect the MONO LOW PASS jack to the

INPUT jack of the subwoofer amplifier, and connect the speaker

terminals of the subwoofer amplifier to the subwoofer.

If you wish to obtain more presence in your listening room, the

use of two subwoofers is recommended. To connect two subwoofers

to this unit, connect the “left” SPLIT LOW PASS jack to the INPUT

jack of the amplifier driving the left subwoofer, and the “right” SPLIT

LOW PASS jack to the INPUT jack of the amplifier driving the right

subwoofer, and then connect each subwoofer to the corresponding

amplifier.

With some subwoofers, including the Yamaha Active Servo

Processing Subwoofer System, the amplifier and subwoofer are in

the same unit.

CONNECTING SPEAKER SYSTEMS

Connect the SPEAKERS terminals to your speakers with wire of

the proper gauge, cut as short as possible. If the connections are

faulty, no sound will be heard from the speakers. Make sure that the

polarity of the speaker wires is correct, that is, + and – markings are

observed. If these wires are reversed, the sound will be unnatural

and will lack bass. Do not let the bare speaker wires touch each

other or any other metal part as this could damage this unit and/or

speakers.

Red: positive (+)

Black: negative (–)

1 Unscrew the knob.

2 Insert the bare wire.

3 Tighten the knob and

secure the wire.

NOTE: Use speakers with the specified impedance shown on the

rear of this unit.

NOTE: Banana Plug connections are also possible (except for

Scandinavian models). Simply insert the Banana Plug connector into

the corresponding terminal.
